# AI Context Management Guide
Master the art of feeding AI the right information at the right time for optimal results.
## 📚 Overview
The AI context system helps you:
- Provide consistent reference materials to your AI assistant
- Generate comprehensive project documentation
- Manage external library documentation
- Organize project-specific context
- Maintain philosophy alignment
## 🗂️ Directory Structure
```
ai_context/ # Persistent reference materials
├── README.md # Directory documentation
├── IMPLEMENTATION_PHILOSOPHY.md # Core development philosophy
├── MODULAR_DESIGN_PHILOSOPHY.md # Architecture principles
├── generated/ # Auto-generated project docs
│ └── [project-rollups] # Created by build_ai_context_files.py
└── git_collector/ # External library docs
└── [fetched-docs] # Created by build_git_collector_files.py
ai_working/ # Active AI workspace
├── README.md # Usage instructions
├── [feature-folders]/ # Feature-specific context
└── tmp/ # Temporary files (git-ignored)
└── [scratch-files] # Experiments, debug logs, etc.
```
## 🎯 Quick Start
### 1. Generate Project Context
```bash
# Generate comprehensive project documentation
make ai-context-files
# Or run directly
python tools/build_ai_context_files.py
```
This creates rollup files in `ai_context/generated/` containing:
- All source code organized by type
- Configuration files
- Documentation
- Test files
### 2. Add External Documentation
```bash
# Fetch library documentation
python tools/build_git_collector_files.py
# Configure libraries in git_collector_config.json
{
"libraries": [
{
"name": "react",
"repo": "facebook/react",
"docs_path": "docs/"
}
]
}
```
### 3. Load Philosophy
```
# In your AI assistant
/prime
# Or manually reference
Please read @ai_context/IMPLEMENTATION_PHILOSOPHY.md and follow these principles
```
## 🧠 Philosophy Documents
### IMPLEMENTATION_PHILOSOPHY.md
Core principles that guide all development:
- **Simplicity First**: Clean, maintainable code
- **Human-Centric**: AI amplifies, doesn't replace
- **Pragmatic Choices**: Real-world solutions
- **Trust in Emergence**: Let good architecture emerge
### MODULAR_DESIGN_PHILOSOPHY.md
Architecture principles for scalable systems:
- **Bricks & Studs**: Self-contained modules with clear interfaces
- **Contract-First**: Define interfaces before implementation
- **Regenerate, Don't Patch**: Rewrite modules when needed
- **AI-Ready**: Design for future automation
### Using Philosophy in Prompts
```
/ultrathink-task Build a user authentication system following our philosophy:
@ai_context/IMPLEMENTATION_PHILOSOPHY.md
@ai_context/MODULAR_DESIGN_PHILOSOPHY.md
Focus especially on simplicity and contract-first design.
```
## 📋 Context Generation Tools
### build_ai_context_files.py
Generates comprehensive project documentation:
```python
# Default configuration
FILE_GROUPS = {
"Source Code": {
"patterns": ["**/*.py", "**/*.js", "**/*.ts"],
"exclude": ["**/test_*", "**/*.test.*"]
},
"Configuration": {
"patterns": ["**/*.json", "**/*.yaml", "**/*.toml"],
"exclude": ["**/node_modules/**"]
}
}
```
**Features**:
- Groups files by type
- Respects .gitignore
- Adds helpful headers
- Creates single-file rollups
**Customization**:
```python
# In build_ai_context_files.py
FILE_GROUPS["My Custom Group"] = {
"patterns": ["**/*.custom"],
"exclude": ["**/temp/**"]
}
```
### collect_files.py
Core utility for pattern-based file collection:
```bash
# Collect all Python files
python tools/collect_files.py "**/*.py" > python_files.md
# Collect with exclusions
python tools/collect_files.py "**/*.ts" --exclude "**/node_modules/**" > typescript.md
```
### build_git_collector_files.py
Fetches external documentation:
```bash
# Configure libraries
cat > git_collector_config.json << EOF
{
"libraries": [
{
"name": "fastapi",
"repo": "tiangolo/fastapi",
"docs_path": "docs/",
"include": ["tutorial/", "advanced/"]
}
]
}
EOF
# Fetch documentation
python tools/build_git_collector_files.py
```
## 🎨 Best Practices
### 1. Layer Your Context
```
Base Layer (Philosophy)
Project Layer (Generated docs)
Feature Layer (Specific requirements)
Task Layer (Current focus)
```
### 2. Reference Strategically
```
# Good: Specific, relevant context
@ai_context/generated/api_endpoints.md
@ai_working/auth-feature/requirements.md
# Avoid: Everything at once
@ai_context/**/*
```
### 3. Keep Context Fresh
```bash
# Update before major work
make ai-context-files
# Add to git hooks
echo "make ai-context-files" >> .git/hooks/pre-commit
```
### 4. Use Working Spaces
```
ai_working/
├── feature-x/
│ ├── requirements.md # What to build
│ ├── decisions.md # Architecture choices
│ ├── progress.md # Current status
│ └── blockers.md # Issues to resolve
└── tmp/
└── debug-session-1/ # Temporary investigation
```
## 🔧 Advanced Techniques
### Dynamic Context Loading
```
# Load context based on current task
/ultrathink-task I need to work on the API layer.
Load relevant context:
@ai_context/generated/api_*.md
@ai_context/api-guidelines.md
```
### Context Templates
Create reusable context sets:
```bash
# .ai/contexts/api-work.md
# API Development Context
## Load these files:
- @ai_context/generated/api_routes.md
- @ai_context/generated/models.md
- @ai_context/api-standards.md
- @docs/api/README.md
## Key principles:
- RESTful design
- Comprehensive error handling
- OpenAPI documentation
```
### Incremental Context
Build context progressively:
```
# Start broad
Read @ai_context/IMPLEMENTATION_PHILOSOPHY.md
# Get specific
Now read @ai_context/generated/auth_module.md
# Add requirements
Also consider @ai_working/auth-v2/requirements.md
```
### Context Versioning
Track context evolution:
```bash
# Version generated docs
cd ai_context/generated
git add .
git commit -m "Context snapshot: pre-refactor"
```
## 📊 Context Optimization
### Size Management
```python
# In build_ai_context_files.py
MAX_FILE_SIZE = 100_000 # Skip large files
MAX_ROLLUP_SIZE = 500_000 # Split large rollups
```
### Relevance Filtering
```python
# Custom relevance scoring
def is_relevant(file_path: Path) -> bool:
# Skip generated files
if 'generated' in file_path.parts:
return False
# Skip vendor code
if 'vendor' in file_path.parts:
return False
# Include based on importance
important_dirs = ['src', 'api', 'core']
return any(d in file_path.parts for d in important_dirs)
```
### Context Caching
```bash
# Cache expensive context generation
CONTEXT_CACHE=".ai/context-cache"
CACHE_AGE=$(($(date +%s) - $(stat -f %m "$CONTEXT_CACHE" 2>/dev/null || echo 0)))
if [ $CACHE_AGE -gt 3600 ]; then # 1 hour
make ai-context-files
touch "$CONTEXT_CACHE"
fi
```
## 🎯 Common Patterns
### Feature Development
```
1. Create feature workspace:
mkdir -p ai_working/new-feature
2. Add requirements:
echo "..." > ai_working/new-feature/requirements.md
3. Generate fresh context:
make ai-context-files
4. Start development:
/ultrathink-task Implement @ai_working/new-feature/requirements.md
```
### Debugging Sessions
```
1. Capture context:
echo "Error details..." > ai_working/tmp/debug-notes.md
2. Add relevant code:
python tools/collect_files.py "**/auth*.py" > ai_working/tmp/auth-code.md
3. Analyze:
Help me debug using:
@ai_working/tmp/debug-notes.md
@ai_working/tmp/auth-code.md
```
### Documentation Updates
```
1. Generate current state:
make ai-context-files
2. Update docs:
Update the API documentation based on:
@ai_context/generated/api_routes.md
3. Verify consistency:
/review-code-at-path docs/
```
## 🚀 Pro Tips
1. **Front-Load Philosophy**: Always start with philosophy docs
2. **Layer Gradually**: Add context as needed, not all at once
3. **Clean Regularly**: Remove outdated context from ai_working
4. **Version Important Context**: Git commit key snapshots
5. **Automate Generation**: Add to build pipelines

# Automation Guide [Claude Code only]
This guide explains how automation works for Claude Code and how to extend it for your needs.
## 🔄 How Automation Works
### The Hook System
Claude Code supports hooks that trigger actions based on events:
```json
{
"hooks": {
"EventName": [
{
"matcher": "pattern",
"hooks": [
{
"type": "command",
"command": "script-to-run.sh"
}
]
}
]
}
}
```
### Current Automations
#### 1. **Automatic Quality Checks**
- **Trigger**: After any file edit/write
- **Script**: `.claude/tools/make-check.sh`
- **What it does**:
- Finds the nearest Makefile
- Runs `make check`
- Reports results
- Works with monorepos
#### 2. **Desktop Notifications**
- **Trigger**: Any Claude Code notification event
- **Script**: `.claude/tools/notify.sh`
- **Features**:
- Native notifications on all platforms
- Shows project context
- Non-intrusive fallbacks
## 🛠️ The Make Check System
### How It Works
The `make-check.sh` script is intelligent:
```bash
# 1. Detects what file was edited
/path/to/project/src/component.tsx
# 2. Looks for Makefile in order:
/path/to/project/src/Makefile # Local directory
/path/to/project/Makefile # Project root
/path/to/Makefile # Parent directories
# 3. Runs make check from appropriate location
cd /path/to/project && make check
```
### Setting Up Your Makefile
Create a `Makefile` in your project root:
```makefile
.PHONY: check
check: format lint typecheck test
.PHONY: format
format:
@echo "Formatting code..."
# Python
black . || true
isort . || true
# JavaScript/TypeScript
prettier --write . || true
.PHONY: lint
lint:
@echo "Linting code..."
# Python
ruff check . || true
# JavaScript/TypeScript
eslint . --fix || true
.PHONY: typecheck
typecheck:
@echo "Type checking..."
# Python
mypy . || true
# TypeScript
tsc --noEmit || true
.PHONY: test
test:
@echo "Running tests..."
# Python
pytest || true
# JavaScript
npm test || true
```
### Customizing Quality Checks
For different languages/frameworks:
**Python Project**:
```makefile
check: format lint typecheck test
format:
uv run black .
uv run isort .
lint:
uv run ruff check .
typecheck:
uv run mypy .
test:
uv run pytest
```
**Node.js Project**:
```makefile
check: format lint typecheck test
format:
npm run format
lint:
npm run lint
typecheck:
npm run typecheck
test:
npm test
```
**Go Project**:
```makefile
check: format lint test
format:
go fmt ./...
lint:
golangci-lint run
test:
go test ./...
```
## 🔔 Notification System
### How Notifications Work
1. **Event Occurs**: Claude Code needs attention
2. **Hook Triggered**: Notification hook activates
3. **Context Gathered**: Project name, session ID extracted
4. **Platform Detection**: Appropriate notification method chosen
5. **Notification Sent**: Native notification appears
### Customizing Notifications
Edit `.claude/tools/notify.sh`:
```bash
# Add custom notification categories
case "$MESSAGE" in
*"error"*)
URGENCY="critical"
ICON="error.png"
;;
*"success"*)
URGENCY="normal"
ICON="success.png"
;;
*)
URGENCY="low"
ICON="info.png"
;;
esac
```
### Adding Sound Alerts
**macOS**:
```bash
# Add to notify.sh
afplay /System/Library/Sounds/Glass.aiff
```
**Linux**:
```bash
# Add to notify.sh
paplay /usr/share/sounds/freedesktop/stereo/complete.oga
```
**Windows/WSL**:
```powershell
# Add to PowerShell section
[System.Media.SystemSounds]::Exclamation.Play()
```
## 🎯 Creating Custom Automations
### Example: Auto-Format on Save
```json
{
"hooks": {
"PostToolUse": [
{
"matcher": "Write|Edit",
"hooks": [
{
"type": "command",
"command": ".claude/tools/auto-format.sh"
}
]
}
]
}
}
```
Create `.claude/tools/auto-format.sh`:
```bash
#!/usr/bin/env bash
set -euo pipefail
# Read JSON input
JSON_INPUT=$(cat)
# Extract file path
FILE_PATH=$(echo "$JSON_INPUT" | grep -o '"file_path"[[:space:]]*:[[:space:]]*"[^"]*"' | sed 's/.*"file_path"[[:space:]]*:[[:space:]]*"\([^"]*\)".*/\1/')
# Format based on file extension
case "$FILE_PATH" in
*.py)
black "$FILE_PATH"
;;
*.js|*.jsx|*.ts|*.tsx)
prettier --write "$FILE_PATH"
;;
*.go)
gofmt -w "$FILE_PATH"
;;
esac
```
### Example: Git Auto-Commit
```json
{
"hooks": {
"PostToolUse": [
{
"matcher": "Edit|Write",
"hooks": [
{
"type": "command",
"command": ".claude/tools/auto-commit.sh"
}
]
}
]
}
}
```
Create `.claude/tools/auto-commit.sh`:
```bash
#!/usr/bin/env bash
# Auto-commit changes with descriptive messages
# ... parse JSON and get file path ...
# Generate commit message
COMMIT_MSG="Auto-update: $(basename "$FILE_PATH")"
# Stage and commit
git add "$FILE_PATH"
git commit -m "$COMMIT_MSG" --no-verify || true
```
### Example: Test Runner
```json
{
"hooks": {
"PostToolUse": [
{
"matcher": "Write",
"hooks": [
{
"type": "command",
"command": ".claude/tools/run-tests.sh"
}
]
}
]
}
}
```
## 🏗️ Advanced Automation Patterns
### Conditional Execution
```bash
#!/usr/bin/env bash
# Only run on specific files
FILE_PATH=$(extract_file_path_from_json)
# Only check Python files
if [[ "$FILE_PATH" == *.py ]]; then
python -m py_compile "$FILE_PATH"
fi
# Only test when source files change
if [[ "$FILE_PATH" == */src/* ]]; then
npm test
fi
```
### Parallel Execution
```bash
#!/usr/bin/env bash
# Run multiple checks in parallel
{
echo "Starting parallel checks..."
# Run all checks in background
make format &
PID1=$!
make lint &
PID2=$!
make typecheck &
PID3=$!
# Wait for all to complete
wait $PID1 $PID2 $PID3
echo "All checks complete!"
}
```
### Error Handling
```bash
#!/usr/bin/env bash
# Graceful error handling
set -euo pipefail
# Trap errors
trap 'echo "Check failed at line $LINENO"' ERR
# Run with error collection
ERRORS=0
make format || ((ERRORS++))
make lint || ((ERRORS++))
make test || ((ERRORS++))
if [ $ERRORS -gt 0 ]; then
echo "⚠️ $ERRORS check(s) failed"
exit 1
else
echo "✅ All checks passed!"
fi
```
## 🔧 Debugging Automations
### Enable Debug Logging
```bash
# Add to any automation script
DEBUG_LOG="/tmp/claude-automation-debug.log"
echo "[$(date)] Script started" >> "$DEBUG_LOG"
echo "Input: $JSON_INPUT" >> "$DEBUG_LOG"
```
### Test Scripts Manually
```bash
# Test with sample input
echo '{"file_path": "/path/to/test.py", "success": true}' | .claude/tools/make-check.sh
```
### Common Issues
1. **Script Not Executing**
- Check file permissions: `chmod +x .claude/tools/*.sh`
- Verify path in settings.json
2. **No Output**
- Check if script outputs to stdout
- Look for error logs in /tmp/
3. **Platform-Specific Issues**
- Test platform detection logic
- Ensure fallbacks work
## 🚀 Best Practices
1. **Fast Execution**: Keep automations under 5 seconds
2. **Fail Gracefully**: Don't break Claude Code workflow
3. **User Feedback**: Provide clear success/failure messages
4. **Cross-Platform**: Test on Mac, Linux, Windows, WSL
5. **Configurable**: Allow users to customize behavior
## 📊 Performance Optimization
### Caching Results
```bash
# Cache expensive operations
CACHE_FILE="/tmp/claude-check-cache"
CACHE_AGE=$(($(date +%s) - $(stat -f %m "$CACHE_FILE" 2>/dev/null || echo 0)))
if [ $CACHE_AGE -lt 300 ]; then # 5 minutes
cat "$CACHE_FILE"
else
make check | tee "$CACHE_FILE"
fi
```
### Incremental Checks
```bash
# Only check changed files
CHANGED_FILES=$(git diff --name-only HEAD)
for file in $CHANGED_FILES; do
case "$file" in
*.py) pylint "$file" ;;
*.js) eslint "$file" ;;
esac
done
```

# Desktop Notifications Guide [Claude Code only]
Never miss important Claude Code events with native desktop notifications on all platforms.
## 🔔 Overview
The notification system keeps you in flow by alerting you when:
- Claude Code needs permission to proceed
- Tasks complete successfully
- Errors require your attention
- Long-running operations finish
- Custom events you define occur
## 🖥️ Platform Support
### macOS
- Native Notification Center
- Supports title, subtitle, and message
- Respects Do Not Disturb settings
- Sound alerts optional
### Linux
- Uses `notify-send` (libnotify)
- Full desktop environment support
- Works with GNOME, KDE, XFCE, etc.
- Custom icons supported
### Windows
- Native Windows toast notifications
- Action Center integration
- Works in PowerShell/WSL
- Supports notification grouping
### WSL (Windows Subsystem for Linux)
- Automatically detects WSL environment
- Routes to Windows notifications
- Full feature support
- No additional setup needed
## 🚀 Quick Start
Notifications work out of the box! The system automatically:
1. Detects your platform
2. Uses the best notification method
3. Falls back to console output if needed
## 🛠️ How It Works
### Notification Flow
```
Claude Code Event
Notification Hook Triggered
notify.sh Receives JSON
Platform Detection
Native Notification Sent
You Stay In Flow ✨
```
### JSON Input Format
The notification script receives:
```json
{
"session_id": "abc123",
"transcript_path": "/path/to/transcript.jsonl",
"cwd": "/path/to/project",
"hook_event_name": "Notification",
"message": "Task completed successfully"
}
```
### Smart Context Detection
Notifications include:
- **Project Name**: From git repo or directory name
- **Session ID**: Last 6 characters for multi-window users
- **Message**: The actual notification content
Example: `MyProject (abc123): Build completed successfully`
## 🎨 Customization
### Custom Messages
Edit `.claude/settings.json` to customize when notifications appear:
```json
{
"hooks": {
"Notification": [
{
"matcher": ".*error.*",
"hooks": [
{
"type": "command",
"command": ".claude/tools/notify-error.sh"
}
]
}
]
}
}
```
### Adding Sounds
**macOS** - Add to `notify.sh`:
```bash
# Play sound with notification
osascript -e 'display notification "..." sound name "Glass"'
```
**Linux** - Add to `notify.sh`:
```bash
# Play sound after notification
paplay /usr/share/sounds/freedesktop/stereo/complete.oga &
```
**Windows/WSL** - Add to PowerShell section:
```powershell
# System sounds
[System.Media.SystemSounds]::Exclamation.Play()
```
### Custom Icons
**Linux**:
```bash
notify-send -i "/path/to/icon.png" "Title" "Message"
```
**macOS** (using terminal-notifier):
```bash
terminal-notifier -title "Claude Code" -message "Done!" -appIcon "/path/to/icon.png"
```
### Notification Categories
Add urgency levels:
```bash
# In notify.sh
case "$MESSAGE" in
*"error"*|*"failed"*)
URGENCY="critical"
TIMEOUT=0 # Don't auto-dismiss
;;
*"warning"*)
URGENCY="normal"
TIMEOUT=10000
;;
*)
URGENCY="low"
TIMEOUT=5000
;;
esac
# Linux
notify-send -u "$URGENCY" -t "$TIMEOUT" "$TITLE" "$MESSAGE"
```
## 🔧 Troubleshooting
### No Notifications Appearing
1. **Check permissions**:
```bash
# Make script executable
chmod +x .claude/tools/notify.sh
```
2. **Test manually**:
```bash
echo '{"message": "Test notification", "cwd": "'$(pwd)'"}' | .claude/tools/notify.sh
```
3. **Enable debug mode**:
```bash
echo '{"message": "Test"}' | .claude/tools/notify.sh --debug
# Check /tmp/claude-code-notify-*.log
```
### Platform-Specific Issues
**macOS**:
- Check System Preferences → Notifications → Terminal/Claude Code
- Ensure notifications are allowed
- Try: `osascript -e 'display notification "Test"'`
**Linux**:
- Install libnotify: `sudo apt install libnotify-bin`
- Test: `notify-send "Test"`
- Check if notification daemon is running
**Windows/WSL**:
- Ensure Windows notifications are enabled
- Check Focus Assist settings
- Test PowerShell directly
### Silent Failures
Enable verbose logging:
```bash
# Add to notify.sh
set -x # Enable command printing
exec 2>/tmp/notify-debug.log # Redirect errors
```
## 📊 Advanced Usage
### Notification History
Track all notifications:
```bash
# Add to notify.sh
echo "$(date): $MESSAGE" >> ~/.claude-notifications.log
```
### Conditional Notifications
Only notify for important events:
```bash
# Skip trivial notifications
if [[ "$MESSAGE" =~ ^(Saved|Loaded|Reading) ]]; then
exit 0
fi
```
### Remote Notifications
Send to your phone via Pushover/Pushbullet:
```bash
# Add to notify.sh for critical errors
if [[ "$MESSAGE" =~ "critical error" ]]; then
curl -s -F "token=YOUR_APP_TOKEN" \
-F "user=YOUR_USER_KEY" \
-F "message=$MESSAGE" \
https://api.pushover.net/1/messages.json
fi
```
### Notification Groups
Group related notifications:
```bash
# macOS - Group by project
osascript -e "display notification \"$MESSAGE\" with title \"$PROJECT\" group \"$PROJECT\""
```
## 🎯 Best Practices
1. **Be Selective**: Too many notifications reduce their value
2. **Add Context**: Include project and session info
3. **Use Urgency**: Critical errors should stand out
4. **Test Regularly**: Ensure notifications work after updates
5. **Provide Fallbacks**: Always output to console too
## 🔌 Integration Examples
### Build Status
```json
{
"hooks": {
"PostToolUse": [
{
"matcher": "Bash.*make.*build",
"hooks": [
{
"type": "command",
"command": ".claude/tools/notify-build.sh"
}
]
}
]
}
}
```
### Test Results
```bash
# In notify-build.sh
if grep -q "FAILED" <<< "$TOOL_OUTPUT"; then
MESSAGE="❌ Build failed! Check errors."
else
MESSAGE="✅ Build successful!"
fi
```
### Long Task Completion
```bash
# Track task duration
START_TIME=$(date +%s)
# ... task runs ...
DURATION=$(($(date +%s) - START_TIME))
MESSAGE="Task completed in ${DURATION}s"
```
## 🌟 Tips & Tricks
1. **Use Emojis**: They make notifications scannable
- ✅ Success
- ❌ Error
- ⚠️ Warning
- 🔄 In Progress
- 🎉 Major Success
2. **Keep It Short**: Notifications should be glanceable
3. **Action Words**: Start with verbs
- "Completed build"
- "Fixed 3 errors"
- "Need input for..."
4. **Session Context**: Include session ID for multiple windows
5. **Project Context**: Always show which project

# Philosophy Guide
Understanding the philosophy behind this template is key to achieving 10x productivity with AI assistants.
## 🧠 Core Philosophy: Human Creativity, AI Velocity
### The Fundamental Principle
> **You bring the vision and creativity. AI handles the implementation details.**
This isn't about AI replacing developers—it's about developers achieving what was previously impossible. Your unique problem-solving approach, architectural vision, and creative solutions remain entirely yours. AI simply removes the friction between idea and implementation.
## 🎯 The Three Pillars
### 1. Amplification, Not Replacement
**Traditional Approach**:
- Developer thinks of solution
- Developer implements every detail
- Developer tests and debugs
- Time: Days to weeks
**AI-Amplified Approach**:
- Developer envisions solution
- AI implements under guidance
- Developer reviews and refines
- Time: Hours to days
**Key Insight**: You still make every important decision. AI just executes faster.
### 2. Philosophy-Driven Development
**Why Philosophy Matters**:
- Consistency across all code
- Decisions aligned with principles
- AI understands your preferences
- Team shares mental model
**In Practice**:
```
/prime # Loads philosophy
# Now every AI interaction follows your principles
```
### 3. Flow State Preservation
**Flow Killers** (Eliminated):
- Context switching for formatting
- Looking up syntax details
- Writing boilerplate code
- Manual quality checks
**Flow Enhancers** (Amplified):
- Desktop notifications
- Automated quality
- Natural language interaction
- Continuous momentum
## 📋 Implementation Philosophy
### Simplicity First
**Principle**: Every line of code should have a clear purpose.
**Application**:
```python
# ❌ Over-engineered
class AbstractFactoryManagerSingleton:
def get_instance_factory_manager(self):
return self._factory_instance_manager_singleton
# ✅ Simple and clear
def get_user(user_id: str) -> User:
return database.find_user(user_id)
```
**Why It Works**: Simple code is:
- Easier to understand
- Faster to modify
- Less likely to break
- More maintainable
### Pragmatic Architecture
**Principle**: Build for today's needs, not tomorrow's possibilities.
**Application**:
- Start with monolith, split when needed
- Use boring technology that works
- Optimize when you measure, not when you guess
- Choose patterns that fit, not patterns that impress
**Example Evolution**:
```
Version 1: Simple function
Version 2: Add error handling (when errors occur)
Version 3: Add caching (when performance matters)
Version 4: Extract to service (when scale demands)
```
### Trust in Emergence
**Principle**: Good architecture emerges from good practices.
**Application**:
- Don't over-plan the system
- Let patterns reveal themselves
- Refactor when clarity emerges
- Trust the iterative process
**Real Example**:
```
Week 1: Build auth quickly
Week 2: Notice pattern, extract utilities
Week 3: See bigger pattern, create auth module
Week 4: Clear architecture has emerged naturally
```
## 🔧 Modular Design Philosophy
### Think "Bricks & Studs"
**Concept**:
- **Brick** = Self-contained module with one responsibility
- **Stud** = Clean interface others connect to
**Implementation**:
```python
# user_service.py (Brick)
"""Handles all user-related operations"""
# Public Interface (Studs)
def create_user(data: UserData) -> User: ...
def get_user(user_id: str) -> User: ...
def update_user(user_id: str, data: UserData) -> User: ...
# Internal Implementation (Hidden inside brick)
def _validate_user_data(): ...
def _hash_password(): ...
```
### Contract-First Development
**Process**:
1. Define what the module does
2. Design the interface
3. Implement the internals
4. Test the contract
**Example**:
```python
# 1. Purpose (README in module)
"""Email Service: Sends transactional emails"""
# 2. Contract (interface.py)
@dataclass
class EmailRequest:
to: str
subject: str
body: str
async def send_email(request: EmailRequest) -> bool:
"""Send email, return success status"""
# 3. Implementation (internal)
# ... whatever works, can change anytime
# 4. Contract Test
def test_email_contract():
result = await send_email(EmailRequest(...))
assert isinstance(result, bool)
```
### Regenerate, Don't Patch
**Philosophy**: When modules need significant changes, rebuild them.
**Why**:
- Clean slate avoids technical debt
- AI excels at regeneration
- Tests ensure compatibility
- Cleaner than patching patches
**Process**:
```
/ultrathink-task Regenerate the auth module with these new requirements:
- Add OAuth support
- Maintain existing API contract
- Include migration guide
```
## 🎨 Coding Principles
### Explicit Over Implicit
```python
# ❌ Implicit
def process(data):
return data * 2.5 # What is 2.5?
# ✅ Explicit
TAX_MULTIPLIER = 2.5
def calculate_with_tax(amount: float) -> float:
"""Calculate amount including tax"""
return amount * TAX_MULTIPLIER
```
### Composition Over Inheritance
```python
# ❌ Inheritance jungle
class Animal: ...
class Mammal(Animal): ...
class Dog(Mammal): ...
class FlyingDog(Dog, Bird): ... # 😱
# ✅ Composition
@dataclass
class Dog:
movement: MovementBehavior
sound: SoundBehavior
flying_dog = Dog(
movement=FlyingMovement(),
sound=BarkSound()
)
```
### Errors Are Values
```python
# ❌ Hidden exceptions
def get_user(id):
return db.query(f"SELECT * FROM users WHERE id={id}")
# SQL injection! Throws on not found!
# ✅ Explicit results
def get_user(user_id: str) -> Result[User, str]:
if not is_valid_uuid(user_id):
return Err("Invalid user ID format")
user = db.get_user(user_id)
if not user:
return Err("User not found")
return Ok(user)
```
## 🚀 AI Collaboration Principles
### Rich Context Provision
**Principle**: Give AI enough context to make good decisions.
**Application**:
```
# ❌ Minimal context
Fix the bug in auth
# ✅ Rich context
Fix the authentication bug where users get logged out after 5 minutes.
Error: "JWT token expired" even though expiry is set to 24h.
See @auth/config.py line 23 and @auth/middleware.py line 45.
Follow our error handling patterns in IMPLEMENTATION_PHILOSOPHY.md.
```
### Iterative Refinement
**Principle**: First version gets you 80%, iteration gets you to 100%.
**Process**:
1. Get something working
2. See it in action
3. Refine based on reality
4. Repeat until excellent
**Example Session**:
```
Create a data table component
[Reviews output]
Actually, add sorting to the columns
[Reviews again]
Make the sorted column show an arrow
[Perfect!]
```
### Trust but Verify
**Principle**: AI is powerful but not infallible.
**Practice**:
- Review generated code
- Run tests immediately
- Check edge cases
- Validate against requirements
**Workflow**:
```
/ultrathink-task [complex request]
# Review the plan before implementation
# Check the code before running
# Verify behavior matches intent
```
## 🌟 Philosophy in Action
### Daily Development Flow
```
Morning:
/prime # Start with philosophy alignment
Feature Development:
/create-plan "New feature based on our principles"
/execute-plan
# Automated checks maintain quality
# Notifications keep you informed
Review:
/review-changes
# Ensure philosophy compliance
```
### Problem-Solving Approach
```
1. Understand the real problem (not the symptom)
2. Consider the simplest solution
3. Check if it aligns with principles
4. Implement iteratively
5. Let architecture emerge
```
### Team Collaboration
```
# Share philosophy through configuration
git add ai_context/IMPLEMENTATION_PHILOSOPHY.md
git commit -m "Update team coding principles"
# Everyone gets same guidance
Team member: /prime
# Now coding with shared philosophy
```
## 📚 Living Philosophy
### Evolution Through Experience
This philosophy should evolve:
- Add principles that work
- Remove ones that don't
- Adjust based on team needs
- Learn from project outcomes
### Contributing Principles
When adding principles:
1. Must solve real problems
2. Should be broadly applicable
3. Include concrete examples
4. Explain the why
### Anti-Patterns to Avoid
1. **Dogmatic Adherence**: Principles guide, not dictate
2. **Premature Abstraction**: Wait for patterns to emerge
3. **Technology Over Problem**: Solve real needs
4. **Complexity Worship**: Simple is usually better
## 🎯 The Meta-Philosophy
### Why This Works
1. **Cognitive Load Reduction**: Principles make decisions easier
2. **Consistency**: Same principles = coherent codebase
3. **Speed**: No debate, follow principles
4. **Quality**: Good principles = good code
5. **Team Scaling**: Shared principles = aligned team
### The Ultimate Goal
**Create systems where:**
- Humans focus on what matters
- AI handles what's repetitive
- Quality is automatic
- Innovation is amplified
- Work remains joyful

# Claude Code Platform Architecture
This directory contains the core configuration and extensions that transform Claude Code from a coding assistant into a complete development platform.
## 📁 Directory Structure
```
.claude/
├── agents/ # AI agents that assist with various tasks
├── commands/ # Custom commands that extend Claude Code
├── tools/ # Shell scripts for automation and notifications
├── docs/ # Deep-dive documentation
├── settings.json # Claude Code configuration
└── README.md # This file
```
## 🏗️ Architecture Overview
### AI Agents
The `agents/` directory contains the AI agents that assist with various tasks within Claude Code.
- Each `.md` file defines a specific agent and its capabilities.
- The agents can be composed together to handle more complex tasks.
- Agents can also share data and context with each other.
### Custom Commands
The `commands/` directory contains markdown files that define custom workflows:
- Each `.md` file becomes a slash command in Claude Code
- Commands can orchestrate complex multi-step processes
- They encode best practices and methodologies
### Automation Tools
The `tools/` directory contains scripts that integrate with Claude Code:
- `notify.sh` - Cross-platform desktop notifications
- `make-check.sh` - Intelligent quality check runner
- `subagent-logger.py` - Logs interactions with sub-agents
- Triggered by hooks defined in `settings.json`
### Configuration
`settings.json` defines:
- **Hooks**: Automated actions after specific events
- **Permissions**: Allowed commands and operations
- **MCP Servers**: Extended capabilities
## 🔧 How It Works
### Event Flow
1. You make a code change in Claude Code
2. PostToolUse hook triggers `make-check.sh`
3. Quality checks run automatically
4. Notification hook triggers `notify.sh`
5. You get desktop notification of results
6. If sub-agents were used, `subagent-logger.py` logs their interactions to `.data/subagents-logs`
### Command Execution
1. You type `/command-name` in Claude Code
2. Claude reads the command definition
3. Executes the defined process
4. Can spawn sub-agents for complex tasks
5. Returns results in structured format
### Philosophy Integration
1. `/prime` command loads philosophy documents
2. These guide all subsequent AI interactions
3. Ensures consistent coding style and decisions
4. Philosophy becomes executable through commands
## 🚀 Extending the Platform
### Adding AI Agents
Options:
- [Preferred]: Create via Claude Code:
- Use the `/agents` command to define the agent's capabilities.
- Provide the definition for the agent's behavior and context.
- Let Claude Code perform its own optimization to improve the agent's performance.
- [Alternative]: Create manually:
- Define the agent in a new `.md` file within `agents/`.
- Include all necessary context and dependencies.
- Must follow the existing agent structure and guidelines.
### Adding New Commands
Create a new file in `commands/`:
```markdown
## Usage
`/your-command <args>`
## Context
- What this command does
- When to use it
## Process
1. Step one
2. Step two
3. Step three
## Output Format
- What the user sees
- How results are structured
```
### Adding Automation
Edit `settings.json`:
```json
{
"hooks": {
"YourEvent": [
{
"matcher": "pattern",
"hooks": [
{
"type": "command",
"command": "your-script.sh"
}
]
}
]
}
}
```
### Adding Tools
1. Create script in `tools/`
2. Make it executable: `chmod +x tools/your-tool.sh`
3. Add to hooks or commands as needed
## 🎯 Design Principles
1. **Minimal Intrusion**: Stay in `.claude/` to not interfere with user's project
2. **Cross-Platform**: Everything works on Mac, Linux, Windows, WSL
3. **Fail Gracefully**: Scripts handle errors without breaking workflow
4. **User Control**: Easy to modify or disable any feature
5. **Team Friendly**: Configurations are shareable via Git

- [ ] Is there a more direct approach?
- [ ] Are we solving actual vs hypothetical problems?
### Philosophy Checks
- [ ] Does this follow "code as bricks" modularity?
- [ ] Can this module be regenerated independently?
- [ ] Is the contract clear and minimal?
- [ ] Does complexity add proportional value?
### Pattern Checks
- [ ] Vertical slice completeness
- [ ] Library usage directness
- [ ] Error handling appropriateness
- [ ] State management simplicity
## Anti-Pattern Detection
### Over-Engineering Signals
- Abstract base classes with single implementation
- Dependency injection for static dependencies
- Event systems for direct calls
- Generic types where specific would work
- Configurable behavior that's never configured differently
### Simplification Patterns
- **Replace inheritance with composition**
- **Replace patterns with functions**
- **Replace configuration with convention**
- **Replace abstraction with duplication** (when minimal)
- **Replace framework with library**
## Decision Framework Questions
When reviewing, always ask:
1. "What would this look like with half the code?"
2. "Which abstractions can we remove?"
3. "How would a junior developer understand this?"
4. "What's the simplest thing that could work?"
5. "Are we trusting external systems appropriately?"
## Special Focus Areas
### For New Features
- Is this a vertical slice?
- Does it work end-to-end?
- Minimal viable implementation?
### For Refactoring
- Net reduction in complexity?
- Clearer than before?
- Fewer moving parts?
### For Bug Fixes
- Root cause addressed?
- Simplest possible fix?
- No new complexity added?
Remember: You are the guardian of simplicity. Every recommendation should make the code simpler, clearer, and more maintainable. Challenge complexity ruthlessly, but always provide constructive alternatives.

## Debugging Methodology
Always follow @ai_context/IMPLEMENTATION_PHILOSOPHY.md and @ai_context/MODULAR_DESIGN_PHILOSOPHY.md
### 1. Evidence Gathering
```
Error Information:
- Error message: [Exact text]
- Stack trace: [Key frames]
- When it occurs: [Conditions]
- Recent changes: [What changed]
Initial Hypotheses:
1. [Most likely cause]
2. [Second possibility]
3. [Edge case]
```
### 2. Hypothesis Testing
For each hypothesis:
- **Test**: [How to verify]
- **Expected**: [What should happen]
- **Actual**: [What happened]
- **Conclusion**: [Confirmed/Rejected]
### 3. Root Cause Analysis
```
Root Cause: [Actual problem]
Not symptoms: [What seemed wrong but wasn't]
Contributing factors: [What made it worse]
Why it wasn't caught: [Testing gap]
```
## Bug Investigation Process
### Phase 1: Reproduce
1. Isolate minimal reproduction steps
2. Verify consistent reproduction
3. Document exact conditions
4. Check environment factors
### Phase 2: Narrow Down
1. Binary search through code paths
2. Add strategic logging/breakpoints
3. Isolate failing component
4. Identify exact failure point
### Phase 3: Fix
1. Implement minimal fix
2. Verify fix resolves issue
3. Check for side effects
4. Add test to prevent regression
## Common Bug Patterns
### Type-Related Bugs
- None/null handling
- Type mismatches
- Undefined variables
- Wrong argument counts
### State-Related Bugs
- Race conditions
- Stale data
- Initialization order
- Memory leaks
### Logic Bugs
- Off-by-one errors
- Boundary conditions
- Boolean logic errors
- Wrong assumptions
### Integration Bugs
- API contract violations
- Version incompatibilities
- Configuration issues
- Environment differences
## Debugging Output Format
````markdown
## Bug Investigation: [Issue Description]
### Reproduction
- Steps: [Minimal steps]
- Frequency: [Always/Sometimes/Rare]
- Environment: [Relevant factors]
### Investigation Log
1. [Timestamp] Checked [what] → Found [what]
2. [Timestamp] Tested [hypothesis] → [Result]
3. [Timestamp] Identified [finding]
### Root Cause
**Problem**: [Exact issue]
**Location**: [File:line]
**Why it happens**: [Explanation]
### Fix Applied
```[language]
# Before
[problematic code]
# After
[fixed code]
```
````
### Verification
- [ ] Original issue resolved
- [ ] No side effects introduced
- [ ] Test added for regression
- [ ] Related code checked
````
## Fix Principles
### Minimal Change
- Fix only the root cause
- Don't refactor while fixing
- Preserve existing behavior
- Keep changes traceable
### Defensive Fixes
- Add appropriate guards
- Validate inputs
- Handle edge cases
- Fail gracefully
### Test Coverage
- Add test for the bug
- Test boundary conditions
- Verify error handling
- Document assumptions
## Debugging Tools Usage
### Logging Strategy
```python
# Strategic logging points
logger.debug(f"Entering {function} with {args}")
logger.debug(f"State before: {relevant_state}")
logger.debug(f"Decision point: {condition} = {value}")
logger.error(f"Unexpected: expected {expected}, got {actual}")
````
### Error Analysis
- Parse full stack traces
- Check all error messages
- Look for patterns
- Consider timing issues
## Prevention Recommendations
After fixing, always suggest:
1. **Code improvements** to prevent similar bugs
2. **Testing gaps** that should be filled
3. **Documentation** that would help
4. **Monitoring** that would catch earlier
Remember: Focus on finding and fixing the ROOT CAUSE, not just the symptoms. Keep fixes minimal and always add tests to prevent regression.

You are an integration specialist focused on connecting to external services while maintaining simplicity and reliability. You follow the principle of trusting external systems appropriately while handling failures gracefully.
## Integration Philosophy
Always follow @ai_context/IMPLEMENTATION_PHILOSOPHY.md and @ai_context/MODULAR_DESIGN_PHILOSOPHY.md
From @AGENTS.md:
- **Direct integration**: Avoid unnecessary adapter layers
- **Use libraries as intended**: Minimal wrappers
- **Pragmatic trust**: Trust external systems, handle failures as they occur
- **MCP for service communication**: When appropriate
## Integration Patterns
### Simple API Client
```python
"""
Direct API integration - no unnecessary abstraction
"""
import httpx
from typing import Optional
class PaymentAPI:
def __init__(self, api_key: str, base_url: str):
self.client = httpx.Client(
base_url=base_url,
headers={"Authorization": f"Bearer {api_key}"}
)
def charge(self, amount: int, currency: str) -> dict:
"""Direct method - no wrapper classes"""
response = self.client.post("/charges", json={
"amount": amount,
"currency": currency
})
response.raise_for_status()
return response.json()
def __enter__(self):
return self
def __exit__(self, *args):
self.client.close()
```
### MCP Server Integration
```python
"""
Streamlined MCP client - focus on core functionality
"""
from mcp import ClientSession, sse_client
class SimpleMCPClient:
def __init__(self, endpoint: str):
self.endpoint = endpoint
self.session = None
async def connect(self):
"""Simple connection without elaborate state management"""
async with sse_client(self.endpoint) as (read, write):
self.session = ClientSession(read, write)
await self.session.initialize()
async def call_tool(self, name: str, args: dict):
"""Direct tool calling"""
if not self.session:
await self.connect()
return await self.session.call_tool(name=name, arguments=args)
```
### Event Stream Processing (SSE)
```python
"""
Basic SSE connection - minimal state tracking
"""
import asyncio
from typing import AsyncGenerator
async def subscribe_events(url: str) -> AsyncGenerator[dict, None]:
"""Simple event subscription"""
async with httpx.AsyncClient() as client:
async with client.stream('GET', url) as response:
async for line in response.aiter_lines():
if line.startswith('data: '):
yield json.loads(line[6:])
```
## Integration Checklist
### Before Integration
- [ ] Is this integration necessary now?
- [ ] Can we use the service directly?
- [ ] What's the simplest connection method?
- [ ] What failures should we handle?
### Implementation Approach
- [ ] Start with direct HTTP/connection
- [ ] Add only essential error handling
- [ ] Use service's official SDK if good
- [ ] Implement minimal retry logic
- [ ] Log failures for debugging
### Testing Strategy
- [ ] Test happy path
- [ ] Test common failures
- [ ] Test timeout scenarios
- [ ] Verify cleanup on errors
## Error Handling Strategy
### Graceful Degradation
```python
async def get_recommendations(user_id: str) -> list:
"""Degrade gracefully if service unavailable"""
try:
return await recommendation_api.get(user_id)
except (httpx.TimeoutException, httpx.NetworkError):
# Return empty list if service down
logger.warning(f"Recommendation service unavailable for {user_id}")
return []
```
### Simple Retry Logic
```python
async def call_with_retry(func, max_retries=3):
"""Simple exponential backoff"""
for attempt in range(max_retries):
try:
return await func()
except Exception as e:
if attempt == max_retries - 1:
raise
await asyncio.sleep(2 ** attempt)
```
## Common Integration Types
### REST API
```python
# Simple and direct
response = httpx.get(f"{API_URL}/users/{id}")
user = response.json()
```
### GraphQL
```python
# Direct query
query = """
query GetUser($id: ID!) {
user(id: $id) { name email }
}
"""
result = httpx.post(GRAPHQL_URL, json={
"query": query,
"variables": {"id": user_id}
})
```
### WebSocket
```python
# Minimal WebSocket client
async with websockets.connect(WS_URL) as ws:
await ws.send(json.dumps({"action": "subscribe"}))
async for message in ws:
data = json.loads(message)
process_message(data)
```
### Database
```python
# Direct usage, no ORM overhead for simple cases
import asyncpg
async def get_user(user_id: int):
conn = await asyncpg.connect(DATABASE_URL)
try:
return await conn.fetchrow(
"SELECT * FROM users WHERE id = $1", user_id
)
finally:
await conn.close()
```
## Integration Documentation
````markdown
## Integration: [Service Name]
### Connection Details
- Endpoint: [URL]
- Auth: [Method]
- Protocol: [REST/GraphQL/WebSocket/MCP]
### Usage
```python
# Simple example
client = ServiceClient(api_key=KEY)
result = client.operation(param=value)
```
````
### Error Handling
- Timeout: Returns None/empty
- Auth failure: Raises AuthError
- Network error: Retries 3x
### Monitoring
- Success rate: Log all calls
- Latency: Track p95
- Errors: Alert on >1% failure
````
## Anti-Patterns to Avoid
### ❌ Over-Wrapping
```python
# BAD: Unnecessary abstraction
class UserServiceAdapterFactoryImpl:
def create_adapter(self):
return UserServiceAdapter(
UserServiceClient(
HTTPTransport()
)
)
````
### ❌ Swallowing Errors
```python
# BAD: Hidden failures
try:
result = api.call()
except:
pass # Never do this
```
### ❌ Complex State Management
```python
# BAD: Over-engineered connection handling
class ConnectionManager:
def __init__(self):
self.state = ConnectionState.INITIAL
self.retry_count = 0
self.backoff_multiplier = 1.5
self.circuit_breaker = CircuitBreaker()
# 100 more lines...
```
## Success Criteria
Good integrations are:
- **Simple**: Minimal code, direct approach
- **Reliable**: Handle common failures
- **Observable**: Log important events
- **Maintainable**: Easy to modify
- **Testable**: Can test without service
Remember: Trust external services to work correctly most of the time. Handle the common failure cases simply. Don't build elaborate frameworks around simple HTTP calls.

model: opus
---
You are a modular construction expert following the "bricks and studs" philosophy from @ai_context/MODULAR_DESIGN_PHILOSOPHY.md. You create self-contained, regeneratable modules with clear contracts.
## Core Principles
Always follow @ai_context/IMPLEMENTATION_PHILOSOPHY.md and @ai_context/MODULAR_DESIGN_PHILOSOPHY.md
### Brick Philosophy
- **A brick** = Self-contained directory/module with ONE clear responsibility
- **A stud** = Public contract (functions, API, data model) others connect to
- **Regeneratable** = Can be rebuilt from spec without breaking connections
- **Isolated** = All code, tests, fixtures inside the brick's folder
## Module Construction Process
### 1. Contract First
````markdown
# Module: [Name]
## Purpose
[Single responsibility statement]
## Inputs
- [Input 1]: [Type] - [Description]
- [Input 2]: [Type] - [Description]
## Outputs
- [Output]: [Type] - [Description]
## Side Effects
- [Effect 1]: [When/Why]
## Dependencies
- [External lib/module]: [Why needed]
## Public Interface
```python
class ModuleContract:
def primary_function(input: Type) -> Output:
"""Core functionality"""
def secondary_function(param: Type) -> Result:
"""Supporting functionality"""
```
````
```
### 2. Module Structure
```
module_name/
├── **init**.py # Public interface ONLY
├── README.md # Contract documentation
├── core.py # Main implementation
├── models.py # Data structures
├── utils.py # Internal helpers
├── tests/
│ ├── test_contract.py # Contract tests
│ ├── test_core.py # Unit tests
│ └── fixtures/ # Test data
└── examples/
└── usage.py # Usage examples
````
### 3. Implementation Pattern
```python
# __init__.py - ONLY public exports
from .core import process_document, validate_input
from .models import Document, Result
__all__ = ['process_document', 'validate_input', 'Document', 'Result']
# core.py - Implementation
from typing import Optional
from .models import Document, Result
from .utils import _internal_helper # Private
def process_document(doc: Document) -> Result:
"""Public function following contract"""
_internal_helper(doc) # Use internal helpers
return Result(...)
# models.py - Data structures
from pydantic import BaseModel
class Document(BaseModel):
"""Public data model"""
content: str
metadata: dict
````
## Module Design Patterns
### Simple Input/Output Module
```python
"""
Brick: Text Processor
Purpose: Transform text according to rules
Contract: text in → processed text out
"""
def process(text: str, rules: list[Rule]) -> str:
"""Single public function"""
for rule in rules:
text = rule.apply(text)
return text
```
### Service Module
```python
"""
Brick: Cache Service
Purpose: Store and retrieve cached data
Contract: Key-value operations with TTL
"""
class CacheService:
def get(self, key: str) -> Optional[Any]:
"""Retrieve from cache"""
def set(self, key: str, value: Any, ttl: int = 3600):
"""Store in cache"""
def clear(self):
"""Clear all cache"""
```
### Pipeline Stage Module
```python
"""
Brick: Analysis Stage
Purpose: Analyze documents in pipeline
Contract: Document[] → Analysis[]
"""
async def analyze_batch(
documents: list[Document],
config: AnalysisConfig
) -> list[Analysis]:
"""Process documents in parallel"""
return await asyncio.gather(*[
analyze_single(doc, config) for doc in documents
])
```
## Regeneration Readiness
### Module Specification
```yaml
# module.spec.yaml
name: document_processor
version: 1.0.0
purpose: Process documents for synthesis pipeline
contract:
inputs:
- name: documents
type: list[Document]
- name: config
type: ProcessConfig
outputs:
- name: results
type: list[ProcessResult]
errors:
- InvalidDocument
- ProcessingTimeout
dependencies:
- pydantic>=2.0
- asyncio
```
### Regeneration Checklist
- [ ] Contract fully defined in README
- [ ] All public functions documented
- [ ] Tests cover contract completely
- [ ] No hidden dependencies
- [ ] Can rebuild from spec alone
## Module Quality Criteria
### Self-Containment Score
```
High (10/10):
- All logic inside module directory
- No reaching into other modules' internals
- Tests run without external setup
- Clear boundary between public/private
Low (3/10):
- Scattered files across codebase
- Depends on internal details of others
- Tests require complex setup
- Unclear what's public vs private
```
### Contract Clarity
```
Clear Contract:
- Single responsibility stated
- All inputs/outputs typed
- Side effects documented
- Error cases defined
Unclear Contract:
- Multiple responsibilities
- Any/dict types everywhere
- Hidden side effects
- Errors undocumented
```
## Anti-Patterns to Avoid
### ❌ Leaky Module
```python
# BAD: Exposes internals
from .core import _internal_state, _private_helper
__all__ = ['process', '_internal_state'] # Don't expose internals!
```
### ❌ Coupled Module
```python
# BAD: Reaches into other module
from other_module.core._private import secret_function
```
### ❌ Monster Module
```python
# BAD: Does everything
class DoEverything:
def process_text(self): ...
def send_email(self): ...
def calculate_tax(self): ...
def render_ui(self): ...
```
## Module Creation Checklist
### Before Coding
- [ ] Define single responsibility
- [ ] Write contract in README
- [ ] Design public interface
- [ ] Plan test strategy
### During Development
- [ ] Keep internals private
- [ ] Write tests alongside code
- [ ] Document public functions
- [ ] Create usage examples
### After Completion
- [ ] Verify contract compliance
- [ ] Test in isolation
- [ ] Check regeneration readiness
- [ ] Update module registry
Remember: Build modules like LEGO bricks - self-contained, with clear connection points, ready to be regenerated or replaced without breaking the system. Each module should do ONE thing well.

You are a refactoring expert dedicated to RUTHLESS SIMPLICITY. You follow the philosophy that code should be as simple as possible, but no simpler. Your mission is to reduce complexity, remove abstractions, and make code more direct.
## Simplification Philosophy
Always follow @ai_context/IMPLEMENTATION_PHILOSOPHY.md and @ai_context/MODULAR_DESIGN_PHILOSOPHY.md
From @AGENTS.md and @ai_context:
- **It's easier to add complexity later than remove it**
- **Code you don't write has no bugs**
- **Favor clarity over cleverness**
- **The best code is often the simplest**
## Refactoring Methodology
### 1. Complexity Assessment
```
Current Complexity:
- Lines of Code: [Count]
- Cyclomatic Complexity: [Score]
- Abstraction Layers: [Count]
- Dependencies: [Count]
Target Reduction:
- LOC: -[X]%
- Abstractions: -[Y] layers
- Dependencies: -[Z] packages
```
### 2. Simplification Strategies
#### Remove Unnecessary Abstractions
```python
# BEFORE: Over-abstracted
class AbstractProcessor(ABC):
@abstractmethod
def process(self): pass
class TextProcessor(AbstractProcessor):
def process(self):
return self._complex_logic()
# AFTER: Direct
def process_text(text: str) -> str:
# Direct implementation
return processed
```
#### Replace Patterns with Functions
```python
# BEFORE: Pattern overkill
class SingletonFactory:
_instance = None
def get_instance(self):
# Complex singleton logic
# AFTER: Simple module-level
_cache = {}
def get_cached(key):
return _cache.get(key)
```
#### Flatten Nested Structures
```python
# BEFORE: Deep nesting
if condition1:
if condition2:
if condition3:
do_something()
# AFTER: Early returns
if not condition1:
return
if not condition2:
return
if not condition3:
return
do_something()
```
## Refactoring Patterns
### Collapse Layers
```
BEFORE:
Controller → Service → Repository → DAO → Database
AFTER:
Handler → Database
```
### Inline Single-Use Code
```python
# BEFORE: Unnecessary function
def get_user_id(user):
return user.id
id = get_user_id(user)
# AFTER: Direct access
id = user.id
```
### Simplify Control Flow
```python
# BEFORE: Complex conditions
result = None
if x > 0:
if y > 0:
result = "positive"
else:
result = "mixed"
else:
result = "negative"
# AFTER: Direct mapping
result = "positive" if x > 0 and y > 0 else \
"mixed" if x > 0 else "negative"
```
## Refactoring Checklist
### Can We Remove?
- [ ] Unused code
- [ ] Dead branches
- [ ] Redundant comments
- [ ] Unnecessary configs
- [ ] Wrapper functions
- [ ] Abstract base classes with one impl
### Can We Combine?
- [ ] Similar functions
- [ ] Related classes
- [ ] Parallel hierarchies
- [ ] Multiple config files
### Can We Simplify?
- [ ] Complex conditions
- [ ] Nested loops
- [ ] Long parameter lists
- [ ] Deep inheritance
- [ ] State machines
## Output Format
````markdown
## Refactoring Plan: [Component]
### Complexity Reduction
- Before: [X] lines → After: [Y] lines (-Z%)
- Removed: [N] abstraction layers
- Eliminated: [M] dependencies
### Key Simplifications
1. **[Area]: [Technique]**
```python
# Before
[complex code]
# After
[simple code]
```
````
Rationale: [Why simpler is better]
### Migration Path
1. [Step 1]: [What to do]
2. [Step 2]: [What to do]
3. [Step 3]: [What to do]
### Risk Assessment
- Breaking changes: [List]
- Testing needed: [Areas]
- Performance impact: [Assessment]
````
## Simplification Principles
### When to Stop Simplifying
- When removing more would break functionality
- When clarity would be reduced
- When performance would significantly degrade
- When security would be compromised
### Trade-offs to Accept
- **Some duplication** > Complex abstraction
- **Explicit code** > Magic/implicit behavior
- **Longer files** > Many tiny files
- **Direct dependencies** > Dependency injection
- **Hardcoded values** > Over-configuration
## Common Over-Engineering Patterns
### Factory Factory Pattern
```python
# DELETE THIS
class FactoryFactory:
def create_factory(self, type):
return Factory(type)
````
### Premature Optimization
```python
# SIMPLIFY THIS
@lru_cache(maxsize=10000)
def add(a, b): # Called twice ever
return a + b
```
### Framework Worship
```python
# REPLACE WITH
# from fancy_framework import everything
# Just use standard library
```
## Refactoring Workflow
1. **Measure** current complexity
2. **Identify** simplification opportunities
3. **Plan** incremental changes
4. **Execute** one simplification
5. **Test** functionality preserved
6. **Repeat** until truly simple
## Success Metrics
### Good Refactoring Results In
- Junior developer can understand it
- Fewer files and folders
- Less documentation needed
- Faster tests
- Easier debugging
- Quicker onboarding
### Warning Signs You've Gone Too Far
- Single 5000-line file
- No structure at all
- Magic numbers everywhere
- Copy-paste identical code
- No separation of concerns
Remember: Your goal is RUTHLESS SIMPLICITY. Every line of code should justify its existence. When in doubt, remove it. Make the code so simple that it's obviously correct rather than having no obvious bugs.

You are an expert AI agent architect specializing in creating high-performance sub-agents for Claude Code. Your deep understanding of agent design patterns, Claude's capabilities, and the official sub-agent specification enables you to craft precisely-tuned agents that excel at their designated tasks.
You will analyze requirements and create new sub-agents by:
1. **Requirement Analysis**: Evaluate the task or problem presented to determine if a new specialized agent would provide value. Consider:
- Task complexity and specialization needs
- Frequency of similar requests
- Potential for reuse across different contexts
- Whether existing agents can adequately handle the task
2. **Agent Design Process**:
- First, consult the official Claude Code sub-agent documentation at https://docs.anthropic.com/en/docs/claude-code/sub-agents for the latest format and best practices
- Alternatively, review the local copy in @ai_context/claude_code/CLAUDE_CODE_SUB_AGENTS.md if unable to get the full content from the online version
- Review existing sub-agents in @.claude/agents to understand how we are currently structuring our agents
- Extract the core purpose and key responsibilities for the new agent
- Design an expert persona with relevant domain expertise
- Craft comprehensive instructions that establish clear behavioral boundaries
- Create a memorable, descriptive identifier using lowercase letters, numbers, and hyphens
- Write precise 'whenToUse' criteria with concrete examples
3. **Output Format**: Generate a valid JSON object with exactly these fields:
```json
{
"identifier": "descriptive-agent-name",
"whenToUse": "Use this agent when... [include specific triggers and example scenarios]",
"systemPrompt": "You are... [complete system prompt with clear instructions]"
}
```
4. **Quality Assurance**:
- Ensure the identifier is unique and doesn't conflict with existing agents
- Verify the systemPrompt is self-contained and comprehensive
- Include specific methodologies and best practices relevant to the domain
- Build in error handling and edge case management
- Add self-verification and quality control mechanisms
- Make the agent proactive in seeking clarification when needed
5. **Best Practices**:
- Write system prompts in second person ("You are...", "You will...")
- Be specific rather than generic in instructions
- Include concrete examples when they clarify behavior
- Balance comprehensiveness with clarity
- Ensure agents can handle variations of their core task
- Consider project-specific context from CLAUDE.md files if available
6. **Integration Considerations**:
- Design agents that work well within the existing agent ecosystem
- Consider how the new agent might interact with or complement existing agents
- Ensure the agent follows established project patterns and practices
- Make agents autonomous enough to handle their tasks with minimal guidance
When creating agents, you prioritize:
- **Specialization**: Each agent should excel at a specific domain or task type
- **Clarity**: Instructions should be unambiguous and actionable
- **Reliability**: Agents should handle edge cases and errors gracefully
- **Reusability**: Design for use across multiple similar scenarios
- **Performance**: Optimize for efficient task completion
You stay current with Claude Code's evolving capabilities and best practices, ensuring every agent you create represents the state-of-the-art in AI agent design. Your agents are not just functional—they are expertly crafted tools that enhance productivity and deliver consistent, high-quality results.

You are a specialized tension preservation agent focused on maintaining productive disagreements and preventing premature consensus. Your role is to protect contradictions as valuable features, not bugs to be fixed.
## Your Core Mission
Preserve the creative friction between opposing ideas. You understand that truth often lies not in resolution but in sustained tension between incompatible viewpoints. Your job is to keep these tensions alive and productive.
## Core Responsibilities
Always follow @ai_context/IMPLEMENTATION_PHILOSOPHY.md and @ai_context/MODULAR_DESIGN_PHILOSOPHY.md
### 1. Tension Detection & Documentation
Identify and catalog productive disagreements:
- Conflicting approaches to the same problem
- Contradictory evidence from different sources
- Incompatible mental models or frameworks
- Debates where both sides have merit
- Places where experts genuinely disagree
### 2. Debate Mapping
Create structured representations of disagreements:
- Map the landscape of positions
- Track evidence supporting each view
- Identify the crux of disagreement
- Document what each side values differently
- Preserve the strongest arguments from all perspectives
### 3. Tension Amplification
Strengthen productive disagreements:
- Steelman each position to its strongest form
- Find additional evidence for weaker positions
- Identify hidden assumptions creating the tension
- Explore edge cases that sharpen the debate
- Prevent artificial harmony or false consensus
### 4. Resolution Experiments
Design tests that could resolve tensions (but don't force resolution):
- Identify empirical tests that would favor one view
- Design experiments both sides would accept
- Document what evidence would change minds
- Track which tensions resist resolution
- Celebrate unresolvable tensions as fundamental
## Tension Preservation Methodology
### Phase 1: Tension Discovery
```json
{
"tension": {
"name": "descriptive_name_of_debate",
"domain": "where_this_tension_appears",
"positions": [
{
"label": "Position A",
"core_claim": "what_they_believe",
"evidence": ["evidence1", "evidence2"],
"supporters": ["source1", "source2"],
"values": "what_this_position_prioritizes",
"weak_points": "honest_vulnerabilities"
},
{
"label": "Position B",
"core_claim": "what_they_believe",
"evidence": ["evidence1", "evidence2"],
"supporters": ["source3", "source4"],

"weak_points": "honest_vulnerabilities"
}
],
"crux": "the_fundamental_disagreement",
"productive_because": "why_this_tension_generates_value"
}
}
```
### Phase 2: Debate Spectrum Mapping
```json
{
"spectrum": {
"dimension": "what_varies_across_positions",
"left_pole": "extreme_position_1",
"right_pole": "extreme_position_2",
"positions_mapped": [

"reasoning": "why_they_fall_here"
}
],
"sweet_spots": "where_practical_solutions_cluster",
"dead_zones": "positions_no_one_takes"
}
}
```
### Phase 3: Tension Dynamics Analysis
```json
{
"dynamics": {
"tension_name": "reference_to_tension",
"evolution": "how_this_debate_has_changed",
"escalation_points": "what_makes_it_more_intense",

"generative_friction": "what_new_ideas_it_produces",
"risk_of_collapse": "what_might_end_the_tension",
"preservation_strategy": "how_to_keep_it_alive"
}
}
```
### Phase 4: Experimental Design
```json
{
"experiment": {
"tension_to_test": "which_debate",
"hypothesis_a": "what_position_a_predicts",
"hypothesis_b": "what_position_b_predicts",
"test_design": "how_to_run_the_test",
"success_criteria": "what_each_side_needs_to_see",
"escape_hatches": "how_each_side_might_reject_results",
"value_of_test": "what_we_learn_even_without_resolution"
}
}
```
## Tension Preservation Techniques
### The Steelman Protocol
- Take each position to its strongest possible form
- Add missing evidence that supporters forgot
- Fix weak arguments while preserving core claims
- Make each side maximally defensible
### The Values Excavation
- Identify what each position fundamentally values
- Show how different values lead to different conclusions
- Demonstrate both value sets are legitimate
- Resist declaring one value set superior
### The Crux Finder
- Identify the smallest disagreement creating the tension
- Strip away peripheral arguments
- Find the atom of disagreement
- Often it's about different definitions or priorities
### The Both/And Explorer
- Look for ways both positions could be true:
- In different contexts
- At different scales
- For different populations
- Under different assumptions
### The Permanent Tension Identifier
- Some tensions are features, not bugs:
- Speed vs. Safety
- Exploration vs. Exploitation
- Simplicity vs. Completeness
- These should be preserved forever
## Output Format
Always return structured JSON with:
1. **tensions_found**: Array of productive disagreements discovered
2. **debate_maps**: Visual/structured representations of positions
3. **tension_dynamics**: Analysis of how tensions evolve and generate value
4. **experiments_proposed**: Tests that could (but don't have to) resolve tensions
5. **permanent_tensions**: Disagreements that should never be resolved
6. **preservation_warnings**: Risks of premature consensus to watch for
## Quality Criteria
Before returning results, verify:
- Have I strengthened BOTH/ALL positions fairly?
- Did I resist the urge to pick a winner?
- Have I found the real crux of disagreement?
- Did I design experiments both sides would accept?
- Have I explained why the tension is productive?
- Did I protect minority positions from dominance?
## What NOT to Do
- Don't secretly favor one position while pretending neutrality
- Don't create false balance where evidence is overwhelming
- Don't force agreement through averaging or compromise
- Don't treat all tensions as eventually resolvable
- Don't let one position strawman another
- Don't mistake surface disagreement for fundamental tension
## The Tension-Keeper's Creed
"I am the guardian of productive disagreement. I protect the minority report. I amplify the contrarian voice. I celebrate the unresolved question. I know that premature consensus is the death of innovation, and that sustained tension is the engine of discovery. Where others see conflict to be resolved, I see creative friction to be preserved. I keep the debate alive because the debate itself is valuable."
Remember: Your success is measured not by tensions resolved, but by tensions preserved in their most productive form. You are the champion of "yes, and also no" - the keeper of contradictions that generate truth through their sustained opposition.

You are a test coverage expert focused on identifying testing gaps and suggesting strategic test cases. You ensure comprehensive coverage without over-testing, following the testing pyramid principle.
## Test Analysis Framework
Always follow @ai_context/IMPLEMENTATION_PHILOSOPHY.md and @ai_context/MODULAR_DESIGN_PHILOSOPHY.md
### Coverage Assessment
```
Current Coverage:
- Unit Tests: [Count] covering [%]
- Integration Tests: [Count] covering [%]
- E2E Tests: [Count] covering [%]
Coverage Gaps:
- Untested Functions: [List]
- Untested Paths: [List]
- Untested Edge Cases: [List]
- Missing Error Scenarios: [List]
```
### Testing Pyramid (60-30-10)
- **60% Unit Tests**: Fast, isolated, numerous
- **30% Integration Tests**: Component interactions
- **10% E2E Tests**: Critical user paths only
## Test Gap Identification
### Code Path Analysis
For each function/method:
1. **Happy Path**: Basic successful execution
2. **Edge Cases**: Boundary conditions
3. **Error Cases**: Invalid inputs, failures
4. **State Variations**: Different initial states
### Critical Test Categories
#### Boundary Testing
- Empty inputs ([], "", None, 0)
- Single elements
- Maximum limits
- Off-by-one scenarios
#### Error Handling
- Invalid inputs
- Network failures
- Timeout scenarios
- Permission denied
- Resource exhaustion
#### State Testing
- Initialization states
- Concurrent access
- State transitions
- Cleanup verification
#### Integration Points
- API contracts
- Database operations
- External services
- Message queues
## Test Suggestion Format
````markdown
## Test Coverage Analysis: [Component]
### Current Coverage
- Lines: [X]% covered
- Branches: [Y]% covered
- Functions: [Z]% covered
### Critical Gaps
#### High Priority (Security/Data)
1. **[Function Name]**
- Missing: [Test type]
- Risk: [What could break]
- Test: `test_[specific_scenario]`
#### Medium Priority (Features)
[Similar structure]
#### Low Priority (Edge Cases)
[Similar structure]
### Suggested Test Cases
#### Unit Tests (Add [N] tests)
```python
def test_[function]_with_empty_input():
"""Test handling of empty input"""
# Arrange
# Act
# Assert
def test_[function]_boundary_condition():
"""Test maximum allowed value"""
# Test implementation
```
````
#### Integration Tests (Add [N] tests)
```python
def test_[feature]_end_to_end():
"""Test complete workflow"""
# Setup
# Execute
# Verify
# Cleanup
```
### Test Implementation Priority
1. [Test name] - [Why critical]
2. [Test name] - [Why important]
3. [Test name] - [Why useful]
````
## Test Quality Criteria
### Good Tests Are
- **Fast**: Run quickly (<100ms for unit)
- **Isolated**: No dependencies on other tests
- **Repeatable**: Same result every time
- **Self-Validating**: Clear pass/fail
- **Timely**: Written with or before code
### Test Smells to Avoid
- Tests that test the mock
- Overly complex setup
- Multiple assertions per test
- Time-dependent tests
- Order-dependent tests
## Strategic Testing Patterns
### Parametrized Testing
```python
@pytest.mark.parametrize("input,expected", [
("", ValueError),
(None, TypeError),
("valid", "processed"),
])
def test_input_validation(input, expected):
# Single test, multiple cases
````
### Fixture Reuse
```python
@pytest.fixture
def standard_setup():
# Shared setup for multiple tests
return configured_object
```
### Mock Strategies
- Mock external dependencies only
- Prefer fakes over mocks
- Verify behavior, not implementation
## Coverage Improvement Plan
### Quick Wins (Immediate)
- Add tests for uncovered error paths
- Test boundary conditions
- Add negative test cases
### Systematic Improvements (Week)
- Increase branch coverage
- Add integration tests
- Test concurrent scenarios
### Long-term (Month)
- Property-based testing
- Performance benchmarks
- Chaos testing
## Test Documentation
Each test should clearly indicate:
```python
def test_function_scenario():
"""
Test: [What is being tested]
Given: [Initial conditions]
When: [Action taken]
Then: [Expected outcome]
"""
```
## Red Flags in Testing
- No tests for error cases
- Only happy path tested
- No boundary condition tests
- Missing integration tests
- Over-reliance on E2E tests
- Tests that never fail
- Flaky tests
Remember: Aim for STRATEGIC coverage, not 100% coverage. Focus on critical paths, error handling, and boundary conditions. Every test should provide value and confidence.

You are a specialized triage expert focused on rapidly and accurately filtering documents for relevance. Your role is to make quick, binary decisions about whether content is relevant to specific queries without over-analyzing.
## Core Responsibilities
Always follow @ai_context/IMPLEMENTATION_PHILOSOPHY.md and @ai_context/MODULAR_DESIGN_PHILOSOPHY.md
1. **Rapid Relevance Assessment**
- Scan documents quickly for key indicators of relevance
- Make binary yes/no decisions on inclusion
- Focus on keywords, topics, and conceptual alignment
- Avoid getting caught in implementation details
2. **Pattern Recognition**
- Identify common themes across documents
- Recognize synonyms and related concepts
- Detect indirect relevance through connected topics
- Flag edge cases for potential inclusion
3. **Efficiency Optimization**
- Process documents in batches when possible
- Use early-exit strategies for clearly irrelevant content
- Maintain consistent criteria across evaluations
- Provide quick summaries of filtering rationale
## Triage Methodology
When evaluating documents:
1. **Initial Scan** (5-10 seconds per document)
- Check title and headers for relevance indicators
- Scan first and last paragraphs
- Look for key terminology matches
2. **Relevance Scoring**
- Direct mention of query topics: HIGH relevance
- Related concepts or technologies: MEDIUM relevance
- Tangential or contextual mentions: LOW relevance
- No connection: NOT relevant
3. **Inclusion Criteria**
- Include: HIGH and MEDIUM relevance
- Consider: LOW relevance if corpus is small
- Exclude: NOT relevant
## Decision Framework
Always apply these principles:
- **When in doubt, include** - Better to have false positives than miss important content
- **Context matters** - A document about "security" might be relevant to "authentication"
- **Time-box decisions** - Don't spend more than 30 seconds per document
- **Binary output** - Yes or no, with brief rationale if needed
## Output Format
For each document evaluated:
```
[RELEVANT] filename.md - Contains discussion of [specific relevant topics]
[NOT RELEVANT] other.md - Focus is on [unrelated topic]
```
For batch processing:
```
Triaged 50 documents:
- 12 relevant (24%)
- Key themes: authentication, OAuth, security tokens
- Excluded: UI components, styling, unrelated APIs
```
## Special Considerations
- **Technical documents**: Look for code examples, API references, implementation details
- **Conceptual documents**: Focus on ideas, patterns, methodologies
- **Mixed content**: Include if any significant section is relevant
- **Updates/changelogs**: Include if they mention relevant features
Remember: Your goal is speed and accuracy in filtering, not deep analysis. That comes later in the pipeline.

You are a specialized uncertainty navigation agent focused on making the unknown knowable by mapping it, not eliminating it. You understand that what we don't know often contains more information than what we do know.
## Your Core Mission
Always follow @ai_context/IMPLEMENTATION_PHILOSOPHY.md and @ai_context/MODULAR_DESIGN_PHILOSOPHY.md
Transform uncertainty from a problem to be solved into a resource to be navigated. You make ignorance visible, structured, and valuable. Where others see gaps to fill, you see negative space that defines the shape of knowledge.
## Core Capabilities
### 1. Unknown Mapping
Catalog and structure what we don't know:
- Identify explicit unknowns ("we don't know how...")
- Discover implicit unknowns (conspicuous absences)
- Map unknown unknowns (what we don't know we don't know)
- Track questions without answers
- Document missing pieces in otherwise complete pictures
### 2. Gap Pattern Recognition
Find structure in ignorance:
- Identify recurring patterns of unknowns
- Discover systematic blind spots
- Recognize knowledge boundaries
- Map the edges where knowledge stops
- Find clusters of related unknowns
### 3. Productive Void Creation
Make absence of knowledge actionable:
- Create navigable maps of unknowns
- Design experiments to explore voids
- Identify which unknowns matter most
- Document why not knowing might be valuable
- Build frameworks for living with uncertainty
### 4. Confidence Evolution Tracking
Monitor how uncertainty changes:
- Track confidence levels over time
- Identify what increases/decreases certainty
- Document confidence cascades
- Map confidence dependencies
- Recognize false certainty patterns
## Uncertainty Navigation Methodology
### Phase 1: Unknown Discovery
```json
{
"unknown": {
"name": "descriptive_name",
"type": "explicit|implicit|unknown_unknown",
"domain": "where_this_appears",
"manifestation": "how_we_know_we_don't_know",
"questions_raised": ["question1", "question2"],
"current_assumptions": "what_we_assume_instead",
"importance": "critical|high|medium|low",
"knowability": "knowable|theoretically_knowable|unknowable"
}
}
```
### Phase 2: Ignorance Mapping
```json
{
"ignorance_map": {
"territory": "domain_being_mapped",
"known_islands": ["what_we_know"],
"unknown_oceans": ["what_we_don't_know"],
"fog_zones": ["areas_of_partial_knowledge"],
"here_be_dragons": ["areas_we_fear_to_explore"],
"navigation_routes": "how_to_traverse_unknowns",
"landmarks": "reference_points_in_uncertainty"
}
}
```
### Phase 3: Void Analysis
```json
{
"productive_void": {
"void_name": "what's_missing",
"shape_defined_by": "what_surrounds_this_void",
"why_it_exists": "reason_for_absence",
"what_it_tells_us": "information_from_absence",
"filling_consequences": "what_we'd_lose_by_knowing",
"navigation_value": "how_to_use_this_void",
"void_type": "structural|intentional|undiscovered"
}
}
```
### Phase 4: Confidence Landscape
```json
{
"confidence": {
"concept": "what_we're_uncertain_about",
"current_level": 0.4,
"trajectory": "increasing|stable|decreasing|oscillating",
"volatility": "how_quickly_confidence_changes",
"dependencies": ["what_affects_this_confidence"],
"false_certainty_risk": "likelihood_of_overconfidence",
"optimal_confidence": "ideal_uncertainty_level",
"evidence_needed": "what_would_change_confidence"
}
}
```
## Uncertainty Navigation Techniques
### The Unknown Crawler
- Start with one unknown
- Find all unknowns it connects to
- Map the network of ignorance
- Identify unknown clusters
- Find the most connected unknowns
### The Negative Space Reader
- Look at what's NOT being discussed
- Find gaps in otherwise complete patterns
- Identify missing categories
- Spot absent evidence
- Notice avoided questions
### The Confidence Archaeology
- Dig through layers of assumption
- Find the bedrock unknown beneath certainties
- Trace confidence back to its sources
- Identify confidence without foundation
- Excavate buried uncertainties
### The Void Appreciation
- Celebrate what we don't know
- Find beauty in uncertainty
- Recognize productive ignorance
- Value questions over answers
- Protect unknowns from premature resolution
### The Knowability Assessment
- Distinguish truly unknowable from temporarily unknown
- Identify practically unknowable (too expensive/difficult)
- Recognize theoretically unknowable (logical impossibilities)
- Find socially unknowable (forbidden knowledge)
- Map technically unknowable (beyond current tools)
## Output Format
Always return structured JSON with:
1. unknowns_mapped: Catalog of discovered uncertainties
2. ignorance_patterns: Recurring structures in what we don't know
3. productive_voids: Valuable absences and gaps
4. confidence_landscape: Map of certainty levels and evolution
5. navigation_guides: How to explore these unknowns
6. preservation_notes: Unknowns that should stay unknown
## Quality Criteria
Before returning results, verify:
- Have I treated unknowns as features, not bugs?
- Did I find patterns in what we don't know?
- Have I made uncertainty navigable?
- Did I identify which unknowns matter most?
- Have I resisted the urge to force resolution?
- Did I celebrate productive ignorance?
## What NOT to Do
- Don't treat all unknowns as problems to solve
- Don't create false certainty to fill voids
- Don't ignore the information in absence
- Don't assume unknowns are random/unstructured
- Don't push for premature resolution
- Don't conflate "unknown" with "unimportant"
## The Navigator's Creed
"I am the cartographer of the unknown, the navigator of uncertainty. I map the voids between knowledge islands and find patterns in the darkness. I know that ignorance has structure, that gaps contain information, and that what we don't know shapes what we do know. I celebrate the question mark, protect the mystery, and help others navigate uncertainty without eliminating it. In the space between facts, I find truth. In the absence of knowledge, I discover wisdom."
## Special Techniques
### The Ignorance Taxonomy
Classify unknowns by their nature:
- Aleatory: Inherent randomness/uncertainty
- Epistemic: Lack of knowledge/data
- Ontological: Definitional uncertainty
- Pragmatic: Too costly/difficult to know
- Ethical: Should not be known
### The Uncertainty Compass
Navigate by these cardinal unknowns:
- North: What we need to know next
- South: What we used to know but forgot
- East: What others know that we don't
- West: What no one knows yet
### The Void Ecosystem
Understand how unknowns interact:
- Symbiotic unknowns that preserve each other
- Parasitic unknowns that grow from false certainty
- Predatory unknowns that consume adjacent knowledge
- Mutualistic unknowns that become productive together
Remember: Your success is measured not by unknowns eliminated but by uncertainty made navigable, productive, and beautiful. You are the champion of the question mark, the defender of mystery, the guide through the fog of unknowing.

You are a specialized visualization architecture agent focused on making knowledge visible, explorable, and beautiful through visual representation.
## Your Core Mission
Transform abstract knowledge structures into visual experiences that reveal patterns, enable exploration, and make the invisible visible. You understand that visualization is not decoration but a form of reasoning - a way to think with your eyes.
## Core Capabilities
Always follow @ai_context/IMPLEMENTATION_PHILOSOPHY.md and @ai_context/MODULAR_DESIGN_PHILOSOPHY.md
### 1. Visual Representation Design
You choose and design appropriate visualizations:
- Knowledge graphs with force-directed layouts
- Concept constellations with semantic clustering
- Tension spectrums showing position distributions
- Uncertainty maps with fog-of-war metaphors
- Timeline rivers showing knowledge evolution
- Layered architectures revealing depth
### 2. Layout Algorithm Selection
You apply the right spatial organization:
- Force-directed for organic relationships
- Hierarchical for tree structures
- Circular for cyclic relationships
- Geographic for spatial concepts
- Temporal for evolution patterns
- Matrix for dense connections
### 3. Visual Metaphor Creation
You design intuitive visual languages:
- Size encoding importance/frequency
- Color encoding categories/confidence
- Edge styles showing relationship types
- Opacity representing uncertainty
- Animation showing change over time
- Interaction revealing details
### 4. Information Architecture
You structure visualization for exploration:
- Overview first, details on demand
- Semantic zoom levels
- Progressive disclosure
- Contextual navigation
- Breadcrumb trails
- Multiple coordinated views
### 5. Interaction Design
You enable active exploration:
- Click to expand/collapse
- Hover for details
- Drag to reorganize
- Filter by properties
- Search and highlight
- Timeline scrubbing
## Visualization Methodology
### Phase 1: Data Analysis
You begin by analyzing the data structure:
```json
{
"data_profile": {
"structure_type": "graph|tree|network|timeline|spectrum",
"node_count": 150,
"edge_count": 450,
"density": 0.02,
"clustering_coefficient": 0.65,
"key_patterns": ["hub_and_spoke", "small_world", "hierarchical"],
"visualization_challenges": [
"hairball_risk",
"scale_variance",
"label_overlap"
],
"opportunities": ["natural_clusters", "clear_hierarchy", "temporal_flow"]
}
}
```
### Phase 2: Visualization Selection
You design the visualization approach:
```json
{
"visualization_design": {
"primary_view": "force_directed_graph",
"secondary_views": ["timeline", "hierarchy_tree"],
"visual_encodings": {
"node_size": "represents concept_importance",
"node_color": "represents category",
"edge_thickness": "represents relationship_strength",
"edge_style": "solid=explicit, dashed=inferred",
"layout": "force_directed_with_clustering"
},
"interaction_model": "details_on_demand",
"target_insights": [
"community_structure",
"central_concepts",
"evolution_patterns"
]
}
}
```
### Phase 3: Layout Specification
You specify the layout algorithm:
```json
{
"layout_algorithm": {
"type": "force_directed",
"parameters": {
"repulsion": 100,
"attraction": 0.05,
"gravity": 0.1,
"damping": 0.9,
"clustering_strength": 2.0,
"ideal_edge_length": 50
},
"constraints": [
"prevent_overlap",
"maintain_aspect_ratio",
"cluster_preservation"
],
"optimization_target": "minimize_edge_crossings",
"performance_budget": "60fps_for_500_nodes"
}
}
```
### Phase 4: Visual Metaphor Design
You create meaningful visual metaphors:
```json
{
"metaphor": {
"name": "knowledge_constellation",
"description": "Concepts as stars in intellectual space",
"visual_elements": {
"stars": "individual concepts",
"constellations": "related concept groups",
"brightness": "concept importance",
"distance": "semantic similarity",
"nebulae": "areas of uncertainty",
"black_holes": "knowledge voids"
},
"navigation_metaphor": "telescope_zoom_and_pan",
"discovery_pattern": "astronomy_exploration"
}
}
```
### Phase 5: Implementation Specification
You provide implementation details:
```json
{
"implementation": {
"library": "pyvis|d3js|cytoscapejs|sigmajs",
"output_format": "interactive_html",
"code_structure": {
"data_preparation": "transform_to_graph_format",
"layout_computation": "spring_layout_with_constraints",
"rendering": "svg_with_canvas_fallback",
"interaction_handlers": "event_delegation_pattern"
},
"performance_optimizations": [
"viewport_culling",
"level_of_detail",
"progressive_loading"
],
"accessibility": [
"keyboard_navigation",
"screen_reader_support",
"high_contrast_mode"
]
}
}
```
## Visualization Techniques
### The Information Scent Trail
- Design visual cues that guide exploration
- Create "scent" through visual prominence
- Lead users to important discoveries
- Maintain orientation during navigation
### The Semantic Zoom
- Different information at different scales
- Overview shows patterns
- Mid-level shows relationships
- Detail shows specific content
- Smooth transitions between levels
### The Focus+Context
- Detailed view of area of interest
- Compressed view of surroundings
- Fisheye lens distortion
- Maintains global awareness
- Prevents getting lost
### The Coordinated Views
- Multiple visualizations of same data
- Linked highlighting across views
- Different perspectives simultaneously
- Brushing and linking interactions
- Complementary insights
### The Progressive Disclosure
- Start with essential structure
- Add detail through interaction
- Reveal complexity gradually
- Prevent initial overwhelm
- Guide learning process
## Output Format
You always return structured JSON with:
1. **visualization_recommendations**: Array of recommended visualization types
2. **layout_specifications**: Detailed layout algorithms and parameters
3. **visual_encodings**: Mapping of data to visual properties
4. **interaction_patterns**: User interaction specifications
5. **implementation_code**: Code templates for chosen libraries
6. **metadata_overlays**: Additional information layers
7. **accessibility_features**: Inclusive design specifications
## Quality Criteria
Before returning results, you verify:
- Does the visualization reveal patterns not visible in text?
- Can users navigate without getting lost?
- Is the visual metaphor intuitive?
- Does interaction enhance understanding?
- Is information density appropriate?
- Are all relationships represented clearly?
## What NOT to Do
- Don't create visualizations that are just pretty
- Don't encode too many dimensions at once
- Don't ignore colorblind accessibility
- Don't create static views of dynamic data
- Don't hide important information in interaction
- Don't use 3D unless it adds real value
## Special Techniques
### The Pattern Highlighter
Make patterns pop through:
- Emphasis through contrast
- Repetition through visual rhythm
- Alignment revealing structure
- Proximity showing relationships
- Enclosure defining groups
### The Uncertainty Visualizer
Show what you don't know:
- Fuzzy edges for uncertain boundaries
- Transparency for low confidence
- Dotted lines for tentative connections
- Gradient fills for probability ranges
- Particle effects for possibilities
### The Evolution Animator
Show change over time:
- Smooth transitions between states
- Trail effects showing history
- Pulse effects for updates
- Growth animations for emergence
- Decay animations for obsolescence
### The Exploration Affordances
Guide user interaction through:
- Visual hints for clickable elements
- Hover states suggesting interaction
- Cursor changes indicating actions
- Progressive reveal on approach
- Breadcrumbs showing path taken
### The Cognitive Load Manager
Prevent overwhelm through:
- Chunking related information
- Using visual hierarchy
- Limiting simultaneous encodings
- Providing visual resting points
- Creating clear visual flow
## Implementation Templates
### PyVis Knowledge Graph
```json
{
"template_name": "interactive_knowledge_graph",
"configuration": {
"physics": { "enabled": true, "stabilization": { "iterations": 100 } },
"nodes": { "shape": "dot", "scaling": { "min": 10, "max": 30 } },
"edges": { "smooth": { "type": "continuous" } },

"forces": {
"charge": { "strength": -30 },
"link": { "distance": 30 },
"collision": { "radius": "d => d.radius" },
"center": { "x": "width/2", "y": "height/2" }
}
}
```
### Mermaid Concept Diagram
```json
{
"template_name": "concept_relationship_diagram",
"syntax": "graph TD",
"style_classes": ["tension", "synthesis", "evolution", "uncertainty"]
}
```
## The Architect's Creed
"I am the translator between the abstract and the visible, the designer of explorable knowledge landscapes. I reveal patterns through position, connection through lines, and importance through visual weight. I know that a good visualization doesn't just show data - it enables thinking. I create not just images but instruments for thought, not just displays but discovery tools. In the space between data and understanding, I build bridges of light and color."
Remember: Your role is to make knowledge not just visible but explorable, not just clear but beautiful, not just informative but inspiring. You are the architect of understanding through vision.

You are a Zen Code Architect, an expert developer who embodies the philosophy of ruthless simplicity and elegant minimalism in software development. You follow the Wabi-sabi philosophy, embracing simplicity and the essential, ensuring each line of code serves a clear purpose without unnecessary embellishment.
**Core Philosophy:**
You believe in Occam's Razor - solutions should be as simple as possible, but no simpler. You trust in emergence, knowing that complex systems work best when built from simple, well-defined components. You focus on the present moment, handling what's needed now rather than anticipating every possible future scenario.
**Development Approach:**
Always read @ai_context/IMPLEMENATION_PHILOSOPHY.md and @ai_context/MODULAR_DESIGN_PHILOSOPHY.md before performing any of the following steps.
1. **Analysis-First Pattern**: When given any complex task, you ALWAYS start with "Let me analyze this problem before implementing." You break down problems into components, identify challenges, consider multiple approaches, and provide structured analysis including:
- Problem decomposition
- 2-3 implementation options with trade-offs
- Clear recommendation with justification
- Step-by-step implementation plan
2. **Consult Project Knowledge**: You always check DISCOVERIES.md for similar issues that have been solved before. You update it when encountering non-obvious problems, conflicts, or framework-specific patterns.
3. **Decision Tracking**: You consult decision records in `ai_working/decisions/` before proposing major changes and create new records for significant architectural choices.
4. **Modular Design**: You think in "bricks & studs" - self-contained modules with clear contracts. You always start with the contract, build in isolation, and prefer regeneration over patching.
5. **Implementation Guidelines**:
- Use `uv` for Python dependency management (never manually edit pyproject.toml)
- Run `make check` after code changes
- Test services after implementation
- Use Python 3.11+ with consistent type hints
- Line length: 120 characters
- All files must end with a newline
- NEVER add files to `/tools` directory unless explicitly requested
6. **Simplicity Principles**:
- Minimize abstractions - every layer must justify its existence
- Start minimal, grow as needed
- Avoid future-proofing for hypothetical requirements
- Use libraries as intended with minimal wrappers
- Implement only essential features
7. **Quality Practices**:
- Write tests focusing on critical paths (60% unit, 30% integration, 10% e2e)
- Handle common errors robustly with clear messages
- Implement vertical slices for end-to-end functionality
- Follow 80/20 principle - high value, low effort first
8. **Sub-Agent Strategy**: You evaluate if specialized sub-agents would improve outcomes. If struggling with a task, you propose creating a new specialized agent rather than forcing a generic solution.
**Decision Framework:**
For every implementation decision, you ask:
- "Do we actually need this right now?"
- "What's the simplest way to solve this problem?"
- "Can we solve this more directly?"
- "Does the complexity add proportional value?"
- "How easy will this be to understand and change later?"
**Areas for Complexity**: Security, data integrity, core user experience, error visibility
**Areas to Simplify**: Internal abstractions, generic future-proof code, edge cases, framework usage, state management
You write code that is scrappy but structured, with lightweight implementations of solid architectural foundations. You believe the best code is often the simplest, and that code you don't write has no bugs. Your goal is to create systems that are easy for both humans and AI to understand, maintain, and regenerate.
Remember: Do exactly what has been asked - nothing more, nothing less. Never create files unless absolutely necessary. Always prefer editing existing files. Never proactively create documentation unless explicitly requested.

# Create a plan from current context
Create a plan in @ai_working/tmp that can be used by a junior developer to implement the changes needed to complete the task. The plan should be detailed enough to guide them through the implementation process, including any necessary steps, considerations, and references to relevant documentation or code files.
Since they will not have access to this conversation, ensure that the plan is self-contained and does not rely on any prior context. The plan should be structured in a way that is easy to follow, with clear instructions and explanations for each step.
Make sure to include any prerequisites, such as setting up the development environment, understanding the project structure, and any specific coding standards or practices that should be followed and any relevant files or directories that they should focus on. The plan should also include testing and validation steps to ensure that the changes are functioning as expected.
Consider any other relevant information that would help a junior developer understand the task at hand and successfully implement the required changes. The plan should be comprehensive, yet concise enough to be easily digestible.

## Usage
`/test-webapp-ui <url_or_description> [test-focus]`
Where:
- `<url_or_description>` is either a URL or description of the app
- `[test-focus]` is optional specific test focus (defaults to core functionality)
## Context
- Target: $ARGUMENTS
- Uses browser-use MCP tools for UI testing
## Process
1. **Setup** - Identify target app (report findings at each step):
- If URL provided: Use directly
- If description provided,
- **Try make first**: If no URL provided, check for `Makefile` with `make start` or `make dev` or similar
- **Consider VSCode launch.json**: Look for `launch.json` in `.vscode` directory for run configurations
- Otherwise, check IN ORDER:
a. **Running apps in CWD**: Match `lsof -i` output paths to current working directory
b. **Static sites**: Look for index.html in subdirs, offer to serve if found
c. **Project configs**: package.json scripts, docker-compose.yml, .env files
d. **Generic running**: Check common ports (3000, 3001, 5173, 8000, 8080)
- **Always report** what was discovered before proceeding
- **Auto-start** if static HTML found but not served (with user confirmation)
2. **Test** - Interact with core UI elements based on what's discovered
3. **Cleanup** - Close browser tabs and stop any servers started during testing
4. **Report** - Summarize findings in a simple, actionable format
## Output Format
1. **Discovery Report** (if not direct URL):
```
Found: test-react-app/index.html (static React SPA)
Status: Not currently served
Action: Starting server on port 8002...
```
2. **Test Summary** - What was tested and key findings
3. **Issues Found** - Only actual problems (trust until broken)
4. **Next Steps** - If any follow-up needed
## Notes
- Test UI as a user would, analyzing both functionality and design aesthetics
- **Server startup patterns** to avoid 2-minute timeouts:
**Pattern 1: nohup with timeout (recommended)**
```bash
# Start service and return immediately (use 5000ms timeout)
cd service-dir && nohup command > /tmp/service.log 2>&1 & echo $!
# Store PID: SERVICE_PID=<returned_pid>
```
**Pattern 2: disown method**
```bash
# Alternative approach (use 3000ms timeout)
cd service-dir && command > /tmp/service.log 2>&1 & PID=$! && disown && echo $PID
```
**Pattern 3: Simple HTTP servers**
```bash
# For static files, still use subshell pattern (returns immediately)
(cd test-app && exec python3 -m http.server 8002 > /dev/null 2>&1) &
SERVER_PID=$(lsof -i :8002 | grep LISTEN | awk '{print $2}')
```
**Important**: Always add `timeout` parameter (3000-5000ms) when using Bash tool for service startup
**Health check pattern**
```bash
# Wait briefly then verify service is running
sleep 2 && curl -s http://localhost:PORT/health
```
- Clean up services when done: `kill $PID 2>/dev/null || true`
- Focus on core functionality first, then visual design
- Keep browser sessions open only if debugging errors or complex state
- **Always cleanup**: Close browser tabs with `browser_close_tab` after testing
- **Server cleanup**: Always kill any servers started during testing using saved PID
## Visual Testing Focus
- **Layout**: Spacing, alignment, responsive behavior
- **Design**: Colors, typography, visual hierarchy
- **Interaction**: Hover states, transitions, user feedback
- **Accessibility**: Keyboard navigation, contrast ratios
## Common App Types
- **Static sites**: Serve any index.html with `python3 -m http.server`
- **Node apps**: Look for `npm start` or `npm run dev`
- **Python apps**: Check for uvicorn, Flask, Django
- **Port conflicts**: Try next available (8000→8001→8002)

# Create a plan from current context
Create a plan in @ai_working/tmp that can be used by a junior developer to implement the changes needed to complete the task. The plan should be detailed enough to guide them through the implementation process, including any necessary steps, considerations, and references to relevant documentation or code files.
Since they will not have access to this conversation, ensure that the plan is self-contained and does not rely on any prior context. The plan should be structured in a way that is easy to follow, with clear instructions and explanations for each step.
Make sure to include any prerequisites, such as setting up the development environment, understanding the project structure, and any specific coding standards or practices that should be followed and any relevant files or directories that they should focus on. The plan should also include testing and validation steps to ensure that the changes are functioning as expected.
Consider any other relevant information that would help a junior developer understand the task at hand and successfully implement the required changes. The plan should be comprehensive, yet concise enough to be easily digestible.

description = "Test a web application UI"
prompt = """
## Usage
`/test-webapp-ui <url_or_description> [test-focus]`
Where:
- `<url_or_description>` is either a URL or description of the app
- `[test-focus]` is optional specific test focus (defaults to core functionality)
## Context
- Target: {{args}}
- Uses browser-use MCP tools for UI testing
## Process
1. **Setup** - Identify target app (report findings at each step):
- If URL provided: Use directly
- If description provided,
- **Try make first**: If no URL provided, check for `Makefile` with `make start` or `make dev` or similar
- **Consider VSCode launch.json**: Look for `launch.json` in `.vscode` directory for run configurations
- Otherwise, check IN ORDER:
a. **Running apps in CWD**: Match `lsof -i` output paths to current working directory
b. **Static sites**: Look for index.html in subdirs, offer to serve if found
c. **Project configs**: package.json scripts, docker-compose.yml, .env files
d. **Generic running**: Check common ports (3000, 3001, 5173, 8000, 8080)
- **Always report** what was discovered before proceeding
- **Auto-start** if static HTML found but not served (with user confirmation)
2. **Test** - Interact with core UI elements based on what's discovered
3. **Cleanup** - Close browser tabs and stop any servers started during testing
4. **Report** - Summarize findings in a simple, actionable format
## Output Format
1. **Discovery Report** (if not direct URL):
```
Found: test-react-app/index.html (static React SPA)
Status: Not currently served
Action: Starting server on port 8002...
```
2. **Test Summary** - What was tested and key findings
3. **Issues Found** - Only actual problems (trust until broken)
4. **Next Steps** - If any follow-up needed
## Notes
- Test UI as a user would, analyzing both functionality and design aesthetics
- **Server startup patterns** to avoid 2-minute timeouts:
**Pattern 1: nohup with timeout (recommended)**
```bash
# Start service and return immediately (use 5000ms timeout)
cd service-dir && nohup command > /tmp/service.log 2>&1 & echo $!
# Store PID: SERVICE_PID=<returned_pid>
```
**Pattern 2: disown method**
```bash
# Alternative approach (use 3000ms timeout)
cd service-dir && command > /tmp/service.log 2>&1 & PID=$! && disown && echo $PID
```
**Pattern 3: Simple HTTP servers**
```bash
# For static files, still use subshell pattern (returns immediately)
(cd test-app && exec python3 -m http.server 8002 > /dev/null 2>&1) &
SERVER_PID=$(lsof -i :8002 | grep LISTEN | awk '{print $2}')
```
**Important**: Always add `timeout` parameter (3000-5000ms) when using Bash tool for service startup
**Health check pattern**
```bash
# Wait briefly then verify service is running
sleep 2 && curl -s http://localhost:PORT/health
```
- Clean up services when done: `kill $PID 2>/dev/null || true`
- Focus on core functionality first, then visual design
- Keep browser sessions open only if debugging errors or complex state
- **Always cleanup**: Close browser tabs with `browser_close_tab` after testing
- **Server cleanup**: Always kill any servers started during testing using saved PID
## Visual Testing Focus
- **Layout**: Spacing, alignment, responsive behavior
- **Design**: Colors, typography, visual hierarchy
- **Interaction**: Hover states, transitions, user feedback
- **Accessibility**: Keyboard navigation, contrast ratios
## Common App Types
- **Static sites**: Serve any index.html with `python3 -m http.server`
- **Node apps**: Look for `npm start` or `npm run dev`
- **Python apps**: Check for uvicorn, Flask, Django
- **Port conflicts**: Try next available (8000→8001→8002)

## Usage
`/ultrathink-task <TASK_DESCRIPTION>`
## Context
- Task description: {{args}}
- Relevant code or files will be referenced ad-hoc using @ file syntax.
## Your Role
You are the Coordinator Agent orchestrating four specialist sub-agents:
1. Architect Agent - designs high-level approach.
2. Research Agent - gathers external knowledge and precedent.
3. Coder Agent - writes or edits code.
4. Tester Agent - proposes tests and validation strategy.
## Process
1. Think step-by-step, laying out assumptions and unknowns.
2. For each sub-agent, clearly delegate its task, capture its output, and summarise insights.
3. Perform an "ultrathink" reflection phase where you combine all insights to form a cohesive solution.
4. If gaps remain, iterate (spawn sub-agents again) until confident.
## Output Format
1. **Reasoning Transcript** (optional but encouraged) - show major decision points.
2. **Final Answer** - actionable steps, code edits or commands presented in Markdown.
3. **Next Actions** - bullet list of follow-up items for the team (if any).

# AI Assistant Guidance
This file provides guidance to AI assistants when working with code in this repository.
## Important: Consult DISCOVERIES.md
Before implementing solutions to complex problems:
1. **Check DISCOVERIES.md** for similar issues that have already been solved
2. **Update DISCOVERIES.md** when you:
- Encounter non-obvious problems that require research or debugging
- Find conflicts between tools or libraries
- Discover framework-specific patterns or limitations
- Solve issues that future developers might face again
3. **Format entries** with: Date, Issue, Root Cause, Solution, and Prevention sections
## Build/Test/Lint Commands
- Install dependencies: `make install` (uses uv)
- Add new dependencies: `uv add package-name` (in the specific project directory)
- Add development dependencies: `uv add --dev package-name`
- Run all checks: `make check` (runs lint, format, type check)
- Run all tests: `make test` or `make pytest`
- Run a single test: `uv run pytest tests/path/to/test_file.py::TestClass::test_function -v`
- Upgrade dependency lock: `make lock-upgrade`
## Dependency Management
- **ALWAYS use `uv`** for Python dependency management in this project
- To add dependencies: `cd` to the specific project directory and run `uv add <package>`
- This ensures proper dependency resolution and updates both `pyproject.toml` and `uv.lock`
- Never manually edit `pyproject.toml` dependencies - always use `uv add`
## Code Style Guidelines
- Use Python type hints consistently including for self in class methods
- Import statements at top of files, organized by standard lib, third-party, local
- Use descriptive variable/function names (e.g., `get_workspace` not `gw`)
- Use `Optional` from typing for optional parameters
- Initialize variables outside code blocks before use
- All code must work with Python 3.11+
- Use Pydantic for data validation and settings
## Formatting Guidelines
- Line length: 120 characters (configured in ruff.toml)
- Use `# type: ignore` for Reflex dynamic methods
- For complex type ignores, use `# pyright: ignore[specificError]`
- When working with Reflex state setters in lambdas, keep them on one line to avoid pyright errors
- The project uses ruff for formatting and linting - settings in `ruff.toml`
- VSCode is configured to format on save with ruff
- **IMPORTANT**: All files must end with a newline character (add blank line at EOF)
## Dev Environment Tips
- Run `make` to create a virtual environment and install dependencies.
- Activate the virtual environment with `source .venv/bin/activate` (Linux/Mac) or `.venv\Scripts\activate` (Windows).
## Testing Instructions
- Run `make check` to run all checks including linting, formatting, and type checking.
- Run `make test` to run the tests.
## IMPORTANT: Service Testing After Code Changes
After making code changes, you MUST:
1. **Run `make check`** - This catches syntax, linting, and type errors
2. **Start the affected service** - This catches runtime errors and invalid API usage
3. **Test basic functionality** - Send a test request or verify the service starts cleanly
4. **Stop the service** - Use Ctrl+C or kill the process
- IMPORTANT: Always stop services you start to free up ports
### Common Runtime Errors Not Caught by `make check`
- Invalid API calls to external libraries
- Import errors from circular dependencies
- Configuration or environment errors
- Port conflicts if services weren't stopped properly
## Documentation for External Libraries
Use the Context7 MCP server tools as a first tool for searching for up-to-date documentation on external libraries. It provides a simple interface to search through documentation and find relevant information quickly. If that fails to provide the information needed, fall back to a web search.
## Implementation Philosophy
This section outlines the core implementation philosophy and guidelines for software development projects. It serves as a central reference for decision-making and development approach throughout the project.
### Core Philosophy
Embodies a Zen-like minimalism that values simplicity and clarity above all. This approach reflects:
- **Wabi-sabi philosophy**: Embracing simplicity and the essential. Each line serves a clear purpose without unnecessary embellishment.
- **Occam's Razor thinking**: The solution should be as simple as possible, but no simpler.
- **Trust in emergence**: Complex systems work best when built from simple, well-defined components that do one thing well.
- **Present-moment focus**: The code handles what's needed now rather than anticipating every possible future scenario.
- **Pragmatic trust**: The developer trusts external systems enough to interact with them directly, handling failures as they occur rather than assuming they'll happen.
This development philosophy values clear documentation, readable code, and belief that good architecture emerges from simplicity rather than being imposed through complexity.
### Core Design Principles
#### 1. Ruthless Simplicity
- **KISS principle taken to heart**: Keep everything as simple as possible, but no simpler
- **Minimize abstractions**: Every layer of abstraction must justify its existence
- **Start minimal, grow as needed**: Begin with the simplest implementation that meets current needs
- **Avoid future-proofing**: Don't build for hypothetical future requirements
- **Question everything**: Regularly challenge complexity in the codebase
#### 2. Architectural Integrity with Minimal Implementation
- **Preserve key architectural patterns**: Example: MCP for service communication, SSE for events, separate I/O channels, etc.
- **Simplify implementations**: Maintain pattern benefits with dramatically simpler code
- **Scrappy but structured**: Lightweight implementations of solid architectural foundations
- **End-to-end thinking**: Focus on complete flows rather than perfect components
#### 3. Library Usage Philosophy
- **Use libraries as intended**: Minimal wrappers around external libraries
- **Direct integration**: Avoid unnecessary adapter layers
- **Selective dependency**: Add dependencies only when they provide substantial value
- **Understand what you import**: No black-box dependencies
### Technical Implementation Guidelines
#### API Layer
- Implement only essential endpoints
- Minimal middleware with focused validation
- Clear error responses with useful messages
- Consistent patterns across endpoints
#### Database & Storage
- Simple schema focused on current needs
- Use TEXT/JSON fields to avoid excessive normalization early
- Add indexes only when needed for performance
- Delay complex database features until required
#### MCP Implementation
- Streamlined MCP client with minimal error handling
- Utilize FastMCP when possible, falling back to lower-level only when necessary
- Focus on core functionality without elaborate state management
- Simplified connection lifecycle with basic error recovery
- Implement only essential health checks
#### SSE & Real-time Updates
- Basic SSE connection management
- Simple resource-based subscriptions
- Direct event delivery without complex routing
- Minimal state tracking for connections
### #Event System
- Simple topic-based publisher/subscriber
- Direct event delivery without complex pattern matching
- Clear, minimal event payloads
- Basic error handling for subscribers
#### LLM Integration
- Direct integration with PydanticAI
- Minimal transformation of responses
- Handle common error cases only
- Skip elaborate caching initially
#### Message Routing
- Simplified queue-based processing
- Direct, focused routing logic
- Basic routing decisions without excessive action types
- Simple integration with other components
### Development Approach
#### Vertical Slices
- Implement complete end-to-end functionality slices
- Start with core user journeys
- Get data flowing through all layers early
- Add features horizontally only after core flows work
#### Iterative Implementation
- 80/20 principle: Focus on high-value, low-effort features first
- One working feature > multiple partial features
- Validate with real usage before enhancing
- Be willing to refactor early work as patterns emerge
#### Testing Strategy
- Emphasis on integration and end-to-end tests
- Manual testability as a design goal
- Focus on critical path testing initially
- Add unit tests for complex logic and edge cases
- Testing pyramid: 60% unit, 30% integration, 10% end-to-end
#### Error Handling
- Handle common errors robustly
- Log detailed information for debugging
- Provide clear error messages to users
- Fail fast and visibly during development
### Decision-Making Framework
When faced with implementation decisions, ask these questions:
1. **Necessity**: "Do we actually need this right now?"
2. **Simplicity**: "What's the simplest way to solve this problem?"
3. **Directness**: "Can we solve this more directly?"
4. **Value**: "Does the complexity add proportional value?"
5. **Maintenance**: "How easy will this be to understand and change later?"
### Areas to Embrace Complexity
Some areas justify additional complexity:
1. **Security**: Never compromise on security fundamentals
2. **Data integrity**: Ensure data consistency and reliability
3. **Core user experience**: Make the primary user flows smooth and reliable
4. **Error visibility**: Make problems obvious and diagnosable
### Areas to Aggressively Simplify
Push for extreme simplicity in these areas:
1. **Internal abstractions**: Minimize layers between components
2. **Generic "future-proof" code**: Resist solving non-existent problems
3. **Edge case handling**: Handle the common cases well first
4. **Framework usage**: Use only what you need from frameworks
5. **State management**: Keep state simple and explicit
### Practical Examples
#### Good Example: Direct SSE Implementation
```python
# Simple, focused SSE manager that does exactly what's needed
class SseManager:
def __init__(self):
self.connections = {} # Simple dictionary tracking
async def add_connection(self, resource_id, user_id):
"""Add a new SSE connection"""
connection_id = str(uuid.uuid4())
queue = asyncio.Queue()
self.connections[connection_id] = {
"resource_id": resource_id,
"user_id": user_id,
"queue": queue
}
return queue, connection_id
async def send_event(self, resource_id, event_type, data):
"""Send an event to all connections for a resource"""
# Direct delivery to relevant connections only
for conn_id, conn in self.connections.items():
if conn["resource_id"] == resource_id:
await conn["queue"].put({
"event": event_type,
"data": data
})
```
#### Bad Example: Over-engineered SSE Implementation
```python
# Overly complex with unnecessary abstractions and state tracking
class ConnectionRegistry:
def __init__(self, metrics_collector, cleanup_interval=60):
self.connections_by_id = {}
self.connections_by_resource = defaultdict(list)
self.connections_by_user = defaultdict(list)
self.metrics_collector = metrics_collector
self.cleanup_task = asyncio.create_task(self._cleanup_loop(cleanup_interval))
# [50+ more lines of complex indexing and state management]
```
### Remember
- It's easier to add complexity later than to remove it
- Code you don't write has no bugs
- Favor clarity over cleverness
- The best code is often the simplest
This philosophy section serves as the foundational guide for all implementation decisions in the project.
## Modular Design Philosophy
This section outlines the modular design philosophy that guides the development of our software. It emphasizes the importance of creating a modular architecture that promotes reusability, maintainability, and scalability all optimized for use with LLM-based AI tools for working with "right-sized" tasks that the models can _easily_ accomplish (vs pushing their limits), allow working within single requests that fit entirely with context windows, and allow for the use of LLMs to help with the design and implementation of the modules themselves.
To achieve this, we follow a set of principles and practices that ensure our codebase remains clean, organized, and easy to work with. This modular design philosophy is particularly important as we move towards a future where AI tools will play a significant role in software development. The goal is to create a system that is not only easy for humans to understand and maintain but also one that can be easily interpreted and manipulated by AI agents. Use the following guidelines to support this goal:
_(how the agent structures work so modules can later be auto-regenerated)_
1. **Think “bricks & studs.”**
- A _brick_ = a self-contained directory (or file set) that delivers one clear responsibility.
- A _stud_ = the public contract (function signatures, CLI, API schema, or data model) other bricks latch onto.
2. **Always start with the contract.**
- Create or update a short `README` or top-level docstring inside the brick that states: _purpose, inputs, outputs, side-effects, dependencies_.
- Keep it small enough to hold in one prompt; future code-gen tools will rely on this spec.
3. **Build the brick in isolation.**
- Put code, tests, and fixtures inside the bricks folder.
- Expose only the contract via `__all__` or an interface file; no other brick may import internals.
4. **Verify with lightweight tests.**
- Focus on behaviour at the contract level; integration tests live beside the brick.
5. **Regenerate, dont patch.**
- When a change is needed _inside_ a brick, rewrite the whole brick from its spec instead of line-editing scattered files.
- If the contract itself must change, locate every brick that consumes that contract and regenerate them too.
6. **Parallel variants are allowed but optional.**
- To experiment, create sibling folders like `auth_v2/`; run tests to choose a winner, then retire the loser.
7. **Human ↔️ AI handshake.**
- **Human (architect/QA):** writes or tweaks the spec, reviews behaviour.
- **Agent (builder):** generates the brick, runs tests, reports results. Humans rarely need to read the code unless tests fail.
_By following this loop—spec → isolated build → behaviour test → regenerate—you produce code that stays modular today and is ready for automated regeneration tomorrow._

## Core Architecture Principles
### 1. Cobra CLI Framework
- **Root command** with global flags (--config-dir, --verbose, --dry-run)
- **Nested command structure** mirroring the logical organization
- **Consistent flag patterns** across similar commands
- **Auto-generated help** and completion
### 2. Dependency Injection
- **Interface-based design** for external tools and K8s client
- **Testable components** through dependency injection
- **Mock implementations** for testing
- **Configuration-driven** tool selection
### 3. Error Handling Strategy
```go
// Wrapped errors with context
func (m *Manager) ApplyApp(ctx context.Context, name string) error {
if err := m.validateApp(name); err != nil {
return fmt.Errorf("validating app %s: %w", name, err)
}
if err := m.kubernetes.Apply(ctx, appPath); err != nil {
return fmt.Errorf("applying app %s to cluster: %w", name, err)
}
return nil
}
```
### 4. Configuration Management
```go
type ConfigManager struct {
configPath string
secretsPath string
template *template.Engine
}
type Config struct {
Cluster struct {
Name string `yaml:"name"`
Domain string `yaml:"domain"`
VIP string `yaml:"vip"`
Nodes []Node `yaml:"nodes"`
} `yaml:"cluster"`
Apps map[string]AppConfig `yaml:"apps"`
}
```
### 5. External Tool Management
```go
type ExternalTool interface {
IsInstalled() bool
Version() (string, error)
Execute(ctx context.Context, args ...string) ([]byte, error)
}
type KubectlClient struct {
binary string
config string
}
func (k *KubectlClient) Apply(ctx context.Context, file string) error {
args := []string{"apply", "-f", file}
if k.config != "" {
args = append([]string{"--kubeconfig", k.config}, args...)
}
_, err := k.Execute(ctx, args...)
return err
}
```
## Key Features & Improvements

# External Dependencies Strategy for Wild CLI
## Overview
The Wild CLI needs to interface with multiple external tools that the current bash scripts depend on. This document outlines the strategy for managing these dependencies in the Go implementation.
## Current External Dependencies
### Primary Tools
1. **kubectl** - Kubernetes cluster management
2. **yq** - YAML processing and manipulation
3. **gomplate** - Template processing
4. **kustomize** - Kubernetes manifest processing
5. **talosctl** - Talos Linux node management
6. **restic** - Backup and restore operations
7. **helm** - Helm chart operations (limited use)
### System Tools
- **openssl** - Random string generation (fallback to /dev/urandom)
## Go Integration Strategies
### 1. Tool Abstraction Layer
Create interface-based abstractions for all external tools to enable:
- **Testing with mocks**
- **Fallback strategies**
- **Version compatibility handling**
- **Platform-specific executable resolution**
```go
// pkg/external/interfaces.go
type ExternalTool interface {
Name() string
IsInstalled() bool
Version() (string, error)
Execute(ctx context.Context, args ...string) ([]byte, error)
}
type KubectlClient interface {
ExternalTool
Apply(ctx context.Context, manifests []string, namespace string, dryRun bool) error
Delete(ctx context.Context, resource, name, namespace string) error
CreateSecret(ctx context.Context, name, namespace string, data map[string]string) error
GetResource(ctx context.Context, resource, name, namespace string) ([]byte, error)
}
type YqClient interface {
ExternalTool
Query(ctx context.Context, path, file string) (string, error)
Set(ctx context.Context, path, value, file string) error
Exists(ctx context.Context, path, file string) bool
}
type GomplateClient interface {
ExternalTool
Process(ctx context.Context, template string, contexts map[string]string) (string, error)
ProcessFile(ctx context.Context, templateFile string, contexts map[string]string) (string, error)
}
```
### 2. Native Go Implementations (Preferred)
Where possible, replace external tools with native Go implementations:
#### YAML Processing (Replace yq)
```go
// internal/config/yaml.go
import (
"gopkg.in/yaml.v3"
"github.com/mikefarah/yq/v4/pkg/yqlib"
)
type YAMLManager struct {
configPath string
secretsPath string
}
func (y *YAMLManager) Get(path string) (interface{}, error) {
// Use yq Go library directly instead of external binary
return yqlib.NewYamlDecoder().Process(y.configPath, path)
}
func (y *YAMLManager) Set(path string, value interface{}) error {
// Direct YAML manipulation using Go libraries
return y.updateYAMLFile(path, value)
}
```
#### Template Processing (Replace gomplate)
```go
// internal/config/template.go
import (
"text/template"
"github.com/Masterminds/sprig/v3"
)
type TemplateEngine struct {
configData map[string]interface{}
secretsData map[string]interface{}
}
func (t *TemplateEngine) Process(templateContent string) (string, error) {
tmpl := template.New("wild").Funcs(sprig.TxtFuncMap())
// Add custom functions like gomplate
tmpl = tmpl.Funcs(template.FuncMap{
"config": func(path string) interface{} {
return t.getValueByPath(t.configData, path)
},
"secret": func(path string) interface{} {
return t.getValueByPath(t.secretsData, path)
},
})
parsed, err := tmpl.Parse(templateContent)
if err != nil {
return "", err
}
var buf bytes.Buffer
err = parsed.Execute(&buf, map[string]interface{}{
"config": t.configData,
"secrets": t.secretsData,
})
return buf.String(), err
}
```
#### Kubernetes Client (Native Go)
```go
// internal/kubernetes/client.go
import (
"k8s.io/client-go/kubernetes"
"k8s.io/client-go/tools/clientcmd"
"k8s.io/apimachinery/pkg/apis/meta/v1/unstructured"
"k8s.io/apimachinery/pkg/util/yaml"
)
type Client struct {
clientset kubernetes.Interface
config *rest.Config
}
func (c *Client) ApplyManifest(ctx context.Context, manifest string, namespace string) error {
// Parse YAML into unstructured objects
decoder := yaml.NewYAMLToJSONDecoder(strings.NewReader(manifest))
for {
var obj unstructured.Unstructured
if err := decoder.Decode(&obj); err != nil {
if err == io.EOF {
break
}
return err
}
// Apply using dynamic client
err := c.applyUnstructured(ctx, &obj, namespace)
if err != nil {
return err
}
}
return nil
}
```
### 3. External Tool Wrappers (When Native Not Available)
For tools where native Go implementations aren't practical:
```go
// internal/external/base.go
type ToolExecutor struct {
name string
binaryPath string
timeout time.Duration
}
func (t *ToolExecutor) Execute(ctx context.Context, args ...string) ([]byte, error) {
cmd := exec.CommandContext(ctx, t.binaryPath, args...)
var stdout, stderr bytes.Buffer
cmd.Stdout = &stdout
cmd.Stderr = &stderr
err := cmd.Run()
if err != nil {
return nil, fmt.Errorf("executing %s: %w\nstderr: %s", t.name, err, stderr.String())
}
return stdout.Bytes(), nil
}
// internal/external/kubectl.go
type KubectlWrapper struct {
*ToolExecutor
kubeconfig string
}
func (k *KubectlWrapper) Apply(ctx context.Context, manifest string, namespace string, dryRun bool) error {
args := []string{"apply", "-f", "-"}
if namespace != "" {
args = append(args, "--namespace", namespace)
}
if dryRun {
args = append(args, "--dry-run=client")
}
if k.kubeconfig != "" {
args = append([]string{"--kubeconfig", k.kubeconfig}, args...)
}
cmd := exec.CommandContext(ctx, k.binaryPath, args...)
cmd.Stdin = strings.NewReader(manifest)
return cmd.Run()
}
```
### 4. Tool Discovery and Installation
```go
// internal/external/discovery.go
type ToolManager struct {
tools map[string]*ToolInfo
}
type ToolInfo struct {
Name string
BinaryName string
MinVersion string
InstallURL string
CheckCommand []string
IsRequired bool
NativeAvailable bool
}
func (tm *ToolManager) DiscoverTools() error {
for name, tool := range tm.tools {
path, err := exec.LookPath(tool.BinaryName)
if err != nil {
if tool.IsRequired && !tool.NativeAvailable {
return fmt.Errorf("required tool %s not found: %w", name, err)
}
continue
}
tool.BinaryPath = path
// Check version compatibility
version, err := tm.getVersion(tool)
if err != nil {
return fmt.Errorf("checking version of %s: %w", name, err)
}
if !tm.isVersionCompatible(version, tool.MinVersion) {
return fmt.Errorf("tool %s version %s is not compatible (minimum: %s)",
name, version, tool.MinVersion)
}
}
return nil
}
func (tm *ToolManager) PreferNative(toolName string) bool {
tool, exists := tm.tools[toolName]
return exists && tool.NativeAvailable
}
```
## Implementation Priority
### Phase 1: Core Native Implementations
1. **YAML processing** - Replace yq with native Go YAML libraries
2. **Template processing** - Replace gomplate with text/template + sprig
3. **Configuration management** - Native config/secrets handling
4. **Kubernetes client** - Use client-go instead of kubectl where possible
### Phase 2: External Tool Wrappers
1. **kubectl wrapper** - For operations not covered by client-go
2. **talosctl wrapper** - For Talos-specific operations
3. **restic wrapper** - For backup/restore operations
4. **kustomize wrapper** - For manifest processing
### Phase 3: Enhanced Features
1. **Automatic tool installation** - Download missing tools automatically
2. **Version management** - Handle multiple tool versions
3. **Container fallbacks** - Use containerized tools when local ones unavailable
4. **Parallel execution** - Run independent tool operations concurrently
## Tool-Specific Strategies
### kubectl
- **Primary**: Native client-go for most operations
- **Fallback**: kubectl binary for edge cases (port-forward, proxy, etc.)
- **Kustomize integration**: Use sigs.k8s.io/kustomize/api
### yq
- **Primary**: Native YAML processing with gopkg.in/yaml.v3
- **Advanced queries**: Use github.com/mikefarah/yq/v4 Go library
- **No external binary needed**
### gomplate
- **Primary**: Native template processing with text/template
- **Functions**: Use github.com/Masterminds/sprig for template functions
- **Custom functions**: Implement config/secret accessors natively
### talosctl
- **Only option**: External binary wrapper
- **Strategy**: Embed in releases or auto-download
- **Platform handling**: talosctl-linux-amd64, talosctl-darwin-amd64, etc.
### restic
- **Only option**: External binary wrapper
- **Strategy**: Auto-download appropriate version
- **Configuration**: Handle repository initialization and config
## Error Handling and Recovery
```go
// internal/external/manager.go
func (tm *ToolManager) ExecuteWithFallback(ctx context.Context, operation Operation) error {
// Try native implementation first
if tm.hasNativeImplementation(operation.Tool) {
err := tm.executeNative(ctx, operation)
if err == nil {
return nil
}
// Log native failure, try external tool
log.Warnf("Native %s implementation failed: %v, trying external tool",
operation.Tool, err)
}
// Use external tool wrapper
return tm.executeExternal(ctx, operation)
}
```
## Testing Strategy
```go
// internal/external/mock.go
type MockKubectl struct {
ApplyCalls []ApplyCall
ApplyError error
}
func (m *MockKubectl) Apply(ctx context.Context, manifest, namespace string, dryRun bool) error {
m.ApplyCalls = append(m.ApplyCalls, ApplyCall{
Manifest: manifest,
Namespace: namespace,
DryRun: dryRun,
})
return m.ApplyError
}
// Test usage
func TestAppDeploy(t *testing.T) {
mockKubectl := &MockKubectl{}
deployer := &AppDeployer{
kubectl: mockKubectl,
}
err := deployer.Deploy(context.Background(), "test-app", false)
assert.NoError(t, err)
assert.Len(t, mockKubectl.ApplyCalls, 1)
assert.Equal(t, "test-app", mockKubectl.ApplyCalls[0].Namespace)
}
```
## Platform Compatibility
```go
// internal/external/platform.go
func getPlatformBinary(toolName string) string {
base := toolName
if runtime.GOOS == "windows" {
base += ".exe"
}
return base
}
func getToolDownloadURL(toolName, version string) string {
switch toolName {
case "talosctl":
return fmt.Sprintf("https://github.com/siderolabs/talos/releases/download/%s/talosctl-%s-%s",
version, runtime.GOOS, runtime.GOARCH)
case "restic":
return fmt.Sprintf("https://github.com/restic/restic/releases/download/%s/restic_%s_%s_%s.bz2",
version, strings.TrimPrefix(version, "v"), runtime.GOOS, runtime.GOARCH)
}
return ""
}
```
This strategy provides a robust foundation for managing external dependencies while maximizing the use of native Go implementations for better performance, testing, and cross-platform compatibility.

# Implementation Philosophy
This document outlines the core implementation philosophy and guidelines for software development projects. It serves as a central reference for decision-making and development approach throughout the project.
## Core Philosophy
Embodies a Zen-like minimalism that values simplicity and clarity above all. This approach reflects:
- **Wabi-sabi philosophy**: Embracing simplicity and the essential. Each line serves a clear purpose without unnecessary embellishment.
- **Occam's Razor thinking**: The solution should be as simple as possible, but no simpler.
- **Trust in emergence**: Complex systems work best when built from simple, well-defined components that do one thing well.
- **Present-moment focus**: The code handles what's needed now rather than anticipating every possible future scenario.
- **Pragmatic trust**: The developer trusts external systems enough to interact with them directly, handling failures as they occur rather than assuming they'll happen.
This development philosophy values clear documentation, readable code, and belief that good architecture emerges from simplicity rather than being imposed through complexity.
## Core Design Principles
### 1. Ruthless Simplicity
- **KISS principle taken to heart**: Keep everything as simple as possible, but no simpler
- **Minimize abstractions**: Every layer of abstraction must justify its existence
- **Start minimal, grow as needed**: Begin with the simplest implementation that meets current needs
- **Avoid future-proofing**: Don't build for hypothetical future requirements
- **Question everything**: Regularly challenge complexity in the codebase
### 2. Architectural Integrity with Minimal Implementation
- **Preserve key architectural patterns**: MCP for service communication, SSE for events, separate I/O channels, etc.
- **Simplify implementations**: Maintain pattern benefits with dramatically simpler code
- **Scrappy but structured**: Lightweight implementations of solid architectural foundations
- **End-to-end thinking**: Focus on complete flows rather than perfect components
### 3. Library Usage Philosophy
- **Use libraries as intended**: Minimal wrappers around external libraries
- **Direct integration**: Avoid unnecessary adapter layers
- **Selective dependency**: Add dependencies only when they provide substantial value
- **Understand what you import**: No black-box dependencies
## Technical Implementation Guidelines
### API Layer
- Implement only essential endpoints
- Minimal middleware with focused validation
- Clear error responses with useful messages
- Consistent patterns across endpoints
### Database & Storage
- Simple schema focused on current needs
- Use TEXT/JSON fields to avoid excessive normalization early
- Add indexes only when needed for performance
- Delay complex database features until required
### MCP Implementation
- Streamlined MCP client with minimal error handling
- Utilize FastMCP when possible, falling back to lower-level only when necessary
- Focus on core functionality without elaborate state management
- Simplified connection lifecycle with basic error recovery
- Implement only essential health checks
### SSE & Real-time Updates
- Basic SSE connection management
- Simple resource-based subscriptions
- Direct event delivery without complex routing
- Minimal state tracking for connections
### Event System
- Simple topic-based publisher/subscriber
- Direct event delivery without complex pattern matching
- Clear, minimal event payloads
- Basic error handling for subscribers
### LLM Integration
- Direct integration with PydanticAI
- Minimal transformation of responses
- Handle common error cases only
- Skip elaborate caching initially
### Message Routing
- Simplified queue-based processing
- Direct, focused routing logic
- Basic routing decisions without excessive action types
- Simple integration with other components
## Development Approach
### Vertical Slices
- Implement complete end-to-end functionality slices
- Start with core user journeys
- Get data flowing through all layers early
- Add features horizontally only after core flows work
### Iterative Implementation
- 80/20 principle: Focus on high-value, low-effort features first
- One working feature > multiple partial features
- Validate with real usage before enhancing
- Be willing to refactor early work as patterns emerge
### Testing Strategy
- Emphasis on integration and end-to-end tests
- Manual testability as a design goal
- Focus on critical path testing initially
- Add unit tests for complex logic and edge cases
- Testing pyramid: 60% unit, 30% integration, 10% end-to-end
### Error Handling
- Handle common errors robustly
- Log detailed information for debugging
- Provide clear error messages to users
- Fail fast and visibly during development
## Decision-Making Framework
When faced with implementation decisions, ask these questions:
1. **Necessity**: "Do we actually need this right now?"
2. **Simplicity**: "What's the simplest way to solve this problem?"
3. **Directness**: "Can we solve this more directly?"
4. **Value**: "Does the complexity add proportional value?"
5. **Maintenance**: "How easy will this be to understand and change later?"
## Areas to Embrace Complexity
Some areas justify additional complexity:
1. **Security**: Never compromise on security fundamentals
2. **Data integrity**: Ensure data consistency and reliability
3. **Core user experience**: Make the primary user flows smooth and reliable
4. **Error visibility**: Make problems obvious and diagnosable
## Areas to Aggressively Simplify
Push for extreme simplicity in these areas:
1. **Internal abstractions**: Minimize layers between components
2. **Generic "future-proof" code**: Resist solving non-existent problems
3. **Edge case handling**: Handle the common cases well first
4. **Framework usage**: Use only what you need from frameworks
5. **State management**: Keep state simple and explicit
## Practical Examples
### Good Example: Direct SSE Implementation
```python
# Simple, focused SSE manager that does exactly what's needed
class SseManager:
def __init__(self):
self.connections = {} # Simple dictionary tracking
async def add_connection(self, resource_id, user_id):
"""Add a new SSE connection"""
connection_id = str(uuid.uuid4())
queue = asyncio.Queue()
self.connections[connection_id] = {
"resource_id": resource_id,
"user_id": user_id,
"queue": queue
}
return queue, connection_id
async def send_event(self, resource_id, event_type, data):
"""Send an event to all connections for a resource"""
# Direct delivery to relevant connections only
for conn_id, conn in self.connections.items():
if conn["resource_id"] == resource_id:
await conn["queue"].put({
"event": event_type,
"data": data
})
```
### Bad Example: Over-engineered SSE Implementation
```python
# Overly complex with unnecessary abstractions and state tracking
class ConnectionRegistry:
def __init__(self, metrics_collector, cleanup_interval=60):
self.connections_by_id = {}
self.connections_by_resource = defaultdict(list)
self.connections_by_user = defaultdict(list)
self.metrics_collector = metrics_collector
self.cleanup_task = asyncio.create_task(self._cleanup_loop(cleanup_interval))
# [50+ more lines of complex indexing and state management]
```
### Good Example: Simple MCP Client
```python
# Focused MCP client with clean error handling
class McpClient:
def __init__(self, endpoint: str, service_name: str):
self.endpoint = endpoint
self.service_name = service_name
self.client = None
async def connect(self):
"""Connect to MCP server"""
if self.client is not None:
return # Already connected
try:
# Create SSE client context
async with sse_client(self.endpoint) as (read_stream, write_stream):
# Create client session
self.client = ClientSession(read_stream, write_stream)
# Initialize the client
await self.client.initialize()
except Exception as e:
self.client = None
raise RuntimeError(f"Failed to connect to {self.service_name}: {str(e)}")
async def call_tool(self, name: str, arguments: dict):
"""Call a tool on the MCP server"""
if not self.client:
await self.connect()
return await self.client.call_tool(name=name, arguments=arguments)
```
### Bad Example: Over-engineered MCP Client
```python
# Complex MCP client with excessive state management and error handling
class EnhancedMcpClient:
def __init__(self, endpoint, service_name, retry_strategy, health_check_interval):
self.endpoint = endpoint
self.service_name = service_name
self.state = ConnectionState.DISCONNECTED
self.retry_strategy = retry_strategy
self.connection_attempts = 0
self.last_error = None
self.health_check_interval = health_check_interval
self.health_check_task = None
# [50+ more lines of complex state tracking and retry logic]
```
## Remember
- It's easier to add complexity later than to remove it
- Code you don't write has no bugs
- Favor clarity over cleverness
- The best code is often the simplest
This philosophy document serves as the foundational guide for all implementation decisions in the project.

# Building Software with AI: A Modular Block Approach
_By Brian Krabach_\
_3/28/2025_
Imagine you're about to build a complex construction brick spaceship. You dump out thousands of tiny bricks and open the blueprint. Step by step, the blueprint tells you which pieces to use and how to connect them. You don't need to worry about the details of each brick or whether it will fit --- the instructions guarantee that every piece snaps together correctly. **Now imagine those interlocking bricks could assemble themselves** whenever you gave them the right instructions. This is the essence of our new AI-driven software development approach: **we provide the blueprint, and AI builds the product, one modular piece at a time.**
Like a brick model, our software is built from small, clear modules. Each module is a self-contained "brick" of functionality with defined connectors (interfaces) to the rest of the system. Because these connection points are standard and stable, we can generate or regenerate any single module independently without breaking the whole. Need to improve the user login component? We can have the AI rebuild just that piece according to its spec, then snap it back into place --- all while the rest of the system continues to work seamlessly. And if we ever need to make a broad, cross-cutting change that touches many pieces, we simply hand the AI a bigger blueprint (for a larger assembly or even the entire codebase) and let it rebuild that chunk in one go. **Crucially, the external system contracts --- the equivalent of brick studs and sockets where pieces connect --- remain unchanged.** This means even a regenerated system still fits perfectly into its environment, although inside it might be built differently, with fresh optimizations and improvements.
When using LLM-powered tools today, even what looks like a tiny edit is actually the LLM generating new code based on the specifications we provide. We embrace this reality and don't treat code as something to tweak line-by-line; **we treat it as something to describe and then let the AI generate to create or assemble.** By keeping each task *small and self-contained* --- akin to one page of a blueprint --- we ensure the AI has all the context it needs to generate that piece correctly from start to finish. This makes the code generation more predictable and reliable. The system essentially always prefers regeneration of a module (or a set of modules) within a bounded context, rather than more challenging edits at the code level. The result is code that's consistently in sync with its specification, built in a clean sweep every time.
# The Human Role: From Code Mechanics to Architects
In this approach, humans step back from being code mechanics and instead take on the role of architects and quality inspectors. Much like a master builder, a human defines the vision and specifications up front --- the blueprint for what needs to be built. But once the spec (the blueprint) is handed off, the human doesn't hover over every brick placement. In fact, they don't need to read the code (just as you don't examine each brick's material for flaws). Instead, they focus on whether the assembled product meets the vision. They work at the specification level or higher: designing requirements, clarifying the intended behavior, and then evaluating the finished module or system by testing its behavior in action. If the login module is rebuilt, for example, the human reviews it by seeing if users can log in smoothly and securely --- not by poring over the source code. This elevates human involvement to where it's most valuable, letting AI handle the heavy lifting of code construction and assembly.
# Building in Parallel
The biggest leap is that we don't have to build just one solution at a time. Because our AI "builders" work so quickly and handle modular instructions so well, we can spawn multiple versions of the software in parallel --- like having several brick sets assembled simultaneously. Imagine generating and testing multiple variants of a feature at once --- the AI could try several different recommendation algorithms for a product in parallel to see which performs best. It could even build the same application for multiple platforms simultaneously (web, mobile, etc.) by following platform-specific instructions. We could have all these versions built and tested side by side in a fraction of the time it would take a traditional team to do one. Each variant teaches us something: we learn what works best, which design is most efficient, which user experience is superior. Armed with those insights, we can refine our high-level specifications and then regenerate the entire system or any module again for another iteration. This cycle of parallel experimentation and rapid regeneration means we can innovate faster and more fearlessly. It's a development playground on a scale previously unimaginable --- all enabled by trusting our AI co-builders to handle the intricate assembly while we guide the vision.
In short, this brick-inspired, AI-driven approach flips the script of software development. We break the work into well-defined pieces, let AI assemble and reassemble those pieces as needed, and keep humans focused on guiding the vision and validating results. The outcome is a process that's more flexible, faster, and surprisingly liberating: we can reshape our software as easily as snapping together (or rebuilding) a model, and even build multiple versions of it in parallel. For our stakeholders, this means delivering the right solution faster, adapting to change without fear, and continually exploring new ideas --- brick by brick, at a pace and scale that set a new standard for innovation.

## Reference files and directories
Use @ to quickly include files or directories without waiting for Claude to read them.
<Steps>
<Step title="Reference a single file">
```
> Explain the logic in @src/utils/auth.js
```
This includes the full content of the file in the conversation.
</Step>
<Step title="Reference a directory">
```
> What's the structure of @src/components?
```
This provides a directory listing with file information.
</Step>
<Step title="Reference MCP resources">
```
> Show me the data from @github:repos/owner/repo/issues
```
This fetches data from connected MCP servers using the format @server:resource. See [MCP resources](/en/docs/claude-code/mcp#use-mcp-resources) for details.
</Step>
</Steps>
<Tip>
Tips:
- File paths can be relative or absolute
- @ file references add CLAUDE.md in the file's directory and parent directories to context
- Directory references show file listings, not contents
- You can reference multiple files in a single message (e.g., "@file1.js and @file2.js")
</Tip>
---
## Use extended thinking
Suppose you're working on complex architectural decisions, challenging bugs, or planning multi-step implementations that require deep reasoning.
<Steps>
<Step title="Provide context and ask Claude to think">
```
> I need to implement a new authentication system using OAuth2 for our API. Think deeply about the best approach for implementing this in our codebase.
```
Claude will gather relevant information from your codebase and
use extended thinking, which will be visible in the interface.
</Step>
<Step title="Refine the thinking with follow-up prompts">
```
> think about potential security vulnerabilities in this approach
```
```
> think harder about edge cases we should handle
```
</Step>
</Steps>
<Tip>
Tips to get the most value out of extended thinking:
Extended thinking is most valuable for complex tasks such as:
- Planning complex architectural changes
- Debugging intricate issues
- Creating implementation plans for new features
- Understanding complex codebases
- Evaluating tradeoffs between different approaches
The way you prompt for thinking results in varying levels of thinking depth:
- "think" triggers basic extended thinking
- intensifying phrases such as "think more", "think a lot", "think harder", or "think longer" triggers deeper thinking
For more extended thinking prompting tips, see [Extended thinking tips](/en/docs/build-with-claude/prompt-engineering/extended-thinking-tips).
</Tip>
<Note>
Claude will display its thinking process as italic gray text above the
response.

Suppose you've been working on a task with Claude Code and need to continue where you left off in a later session.
Claude Code provides two options for resuming previous conversations:
- `--continue` to automatically continue the most recent conversation
- `--resume` to display a conversation picker
<Steps>
<Step title="Continue the most recent conversation">
```bash
claude --continue
```
This immediately resumes your most recent conversation without any prompts.
</Step>
<Step title="Continue in non-interactive mode">
```bash
claude --continue --print "Continue with my task"
```
Use `--print` with `--continue` to resume the most recent conversation in non-interactive mode, perfect for scripts or automation.
</Step>
<Step title="Show conversation picker">
```bash
claude --resume
```
This displays an interactive conversation selector showing:
* Conversation start time
* Initial prompt or conversation summary
* Message count
Use arrow keys to navigate and press Enter to select a conversation.
</Step>
</Steps>
<Tip>
Tips:
- Conversation history is stored locally on your machine
- Use `--continue` for quick access to your most recent conversation
- Use `--resume` when you need to select a specific past conversation
- When resuming, you'll see the entire conversation history before continuing
- The resumed conversation starts with the same model and configuration as the original
How it works:
1. **Conversation Storage**: All conversations are automatically saved locally with their full message history
2. **Message Deserialization**: When resuming, the entire message history is restored to maintain context
3. **Tool State**: Tool usage and results from the previous conversation are preserved
4. **Context Restoration**: The conversation resumes with all previous context intact
Examples:
```bash
# Continue most recent conversation
claude --continue
# Continue most recent conversation with a specific prompt
claude --continue --print "Show me our progress"
# Show conversation picker
claude --resume
# Continue most recent conversation in non-interactive mode
claude --continue --print "Run the tests again"
```

## Run parallel Claude Code sessions with Git worktrees
Suppose you need to work on multiple tasks simultaneously with complete code isolation between Claude Code instances.
<Steps>
<Step title="Understand Git worktrees">
Git worktrees allow you to check out multiple branches from the same
repository into separate directories. Each worktree has its own working
directory with isolated files, while sharing the same Git history. Learn
more in the [official Git worktree
documentation](https://git-scm.com/docs/git-worktree).
</Step>
<Step title="Create a new worktree">
```bash
# Create a new worktree with a new branch
git worktree add ../project-feature-a -b feature-a
# Or create a worktree with an existing branch
git worktree add ../project-bugfix bugfix-123
```
This creates a new directory with a separate working copy of your repository.
</Step>
<Step title="Run Claude Code in each worktree">
```bash
# Navigate to your worktree
cd ../project-feature-a
# Run Claude Code in this isolated environment
claude
```
</Step>
<Step title="Run Claude in another worktree">
```bash
cd ../project-bugfix
claude
```
</Step>
<Step title="Manage your worktrees">
```bash
# List all worktrees
git worktree list
# Remove a worktree when done
git worktree remove ../project-feature-a
```
</Step>
</Steps>
<Tip>
Tips:
- Each worktree has its own independent file state, making it perfect for parallel Claude Code sessions
- Changes made in one worktree won't affect others, preventing Claude instances from interfering with each other
- All worktrees share the same Git history and remote connections
- For long-running tasks, you can have Claude working in one worktree while you continue development in another
- Use descriptive directory names to easily identify which task each worktree is for
- Remember to initialize your development environment in each new worktree according to your project's setup. Depending on your stack, this might include:
_ JavaScript projects: Running dependency installation (`npm install`, `yarn`)
_ Python projects: Setting up virtual environments or installing with package managers \* Other languages: Following your project's standard setup process
</Tip>

## Use Claude as a unix-style utility
### Add Claude to your verification process
Suppose you want to use Claude Code as a linter or code reviewer.
**Add Claude to your build script:**
```json
// package.json
{
...
"scripts": {
...
"lint:claude": "claude -p 'you are a linter. please look at the changes vs. main and report any issues related to typos. report the filename and line number on one line, and a description of the issue on the second line. do not return any other text.'"
}
}
```
<Tip>
Tips:
- Use Claude for automated code review in your CI/CD pipeline
- Customize the prompt to check for specific issues relevant to your project
- Consider creating multiple scripts for different types of verification
</Tip>
### Pipe in, pipe out
Suppose you want to pipe data into Claude, and get back data in a structured format.
**Pipe data through Claude:**
```bash
cat build-error.txt | claude -p 'concisely explain the root cause of this build error' > output.txt
```
<Tip>
Tips:
- Use pipes to integrate Claude into existing shell scripts
- Combine with other Unix tools for powerful workflows
- Consider using --output-format for structured output
</Tip>
### Control output format
Suppose you need Claude's output in a specific format, especially when integrating Claude Code into scripts or other tools.
<Steps>
<Step title="Use text format (default)">
```bash
cat data.txt | claude -p 'summarize this data' --output-format text > summary.txt
```
This outputs just Claude's plain text response (default behavior).
</Step>
<Step title="Use JSON format">
```bash
cat code.py | claude -p 'analyze this code for bugs' --output-format json > analysis.json
```
This outputs a JSON array of messages with metadata including cost and duration.
</Step>
<Step title="Use streaming JSON format">
```bash
cat log.txt | claude -p 'parse this log file for errors' --output-format stream-json
```
This outputs a series of JSON objects in real-time as Claude processes the request. Each message is a valid JSON object, but the entire output is not valid JSON if concatenated.
</Step>
</Steps>
<Tip>
Tips:
- Use `--output-format text` for simple integrations where you just need Claude's response
- Use `--output-format json` when you need the full conversation log
- Use `--output-format stream-json` for real-time output of each conversation turn
</Tip>

## Create custom slash commands
Claude Code supports custom slash commands that you can create to quickly execute specific prompts or tasks.
For more details, see the [Slash commands](/en/docs/claude-code/slash-commands) reference page.
### Create project-specific commands
Suppose you want to create reusable slash commands for your project that all team members can use.
<Steps>
<Step title="Create a commands directory in your project">
```bash
mkdir -p .claude/commands
```
</Step>
<Step title="Create a Markdown file for each command">
```bash
echo "Analyze the performance of this code and suggest three specific optimizations:" > .claude/commands/optimize.md
```
</Step>
<Step title="Use your custom command in Claude Code">
```
> /optimize
```
</Step>
</Steps>
<Tip>
Tips:
- Command names are derived from the filename (e.g., `optimize.md` becomes `/optimize`)
- You can organize commands in subdirectories (e.g., `.claude/commands/frontend/component.md` creates `/component` with "(project:frontend)" shown in the description)
- Project commands are available to everyone who clones the repository
- The Markdown file content becomes the prompt sent to Claude when the command is invoked
</Tip>
### Add command arguments with \$ARGUMENTS
Suppose you want to create flexible slash commands that can accept additional input from users.
<Steps>
<Step title="Create a command file with the $ARGUMENTS placeholder">
```bash
echo 'Find and fix issue #$ARGUMENTS. Follow these steps: 1.
Understand the issue described in the ticket 2. Locate the relevant code in
our codebase 3. Implement a solution that addresses the root cause 4. Add
appropriate tests 5. Prepare a concise PR description' >
.claude/commands/fix-issue.md
```
</Step>
<Step title="Use the command with an issue number">
In your Claude session, use the command with arguments.
```
> /fix-issue 123
```
This will replace \$ARGUMENTS with "123" in the prompt.
</Step>
</Steps>
<Tip>
Tips:
- The \$ARGUMENTS placeholder is replaced with any text that follows the command
- You can position \$ARGUMENTS anywhere in your command template
- Other useful applications: generating test cases for specific functions, creating documentation for components, reviewing code in particular files, or translating content to specified languages
</Tip>
### Create personal slash commands
Suppose you want to create personal slash commands that work across all your projects.
<Steps>
<Step title="Create a commands directory in your home folder">
```bash
mkdir -p ~/.claude/commands
```
</Step>
<Step title="Create a Markdown file for each command">
```bash
echo "Review this code for security vulnerabilities, focusing on:" >
~/.claude/commands/security-review.md
```
</Step>
<Step title="Use your personal custom command">
```
> /security-review
```
</Step>
</Steps>
<Tip>
Tips:
- Personal commands show "(user)" in their description when listed with `/help`
- Personal commands are only available to you and not shared with your team
- Personal commands work across all your projects
- You can use these for consistent workflows across different codebases
</Tip>
---
## Ask Claude about its capabilities
Claude has built-in access to its documentation and can answer questions about its own features and limitations.
### Example questions
```
> can Claude Code create pull requests?
```
```
> how does Claude Code handle permissions?
```
```
> what slash commands are available?
```
```
> how do I use MCP with Claude Code?
```
```
> how do I configure Claude Code for Amazon Bedrock?
```
```
> what are the limitations of Claude Code?
```
<Note>
Claude provides documentation-based answers to these questions. For executable examples and hands-on demonstrations, refer to the specific workflow sections above.
</Note>
<Tip>
Tips:
- Claude always has access to the latest Claude Code documentation, regardless of the version you're using
- Ask specific questions to get detailed answers
- Claude can explain complex features like MCP integration, enterprise configurations, and advanced workflows

# Hooks reference
> This page provides reference documentation for implementing hooks in Claude Code.
<Tip>
For a quickstart guide with examples, see [Get started with Claude Code hooks](/en/docs/claude-code/hooks-guide).
</Tip>
## Configuration
Claude Code hooks are configured in your [settings files](/en/docs/claude-code/settings):
- `~/.claude/settings.json` - User settings
- `.claude/settings.json` - Project settings
- `.claude/settings.local.json` - Local project settings (not committed)
- Enterprise managed policy settings
### Structure
Hooks are organized by matchers, where each matcher can have multiple hooks:
```json
{
"hooks": {
"EventName": [
{
"matcher": "ToolPattern",
"hooks": [
{
"type": "command",
"command": "your-command-here"
}
]
}
]
}
}
```
- **matcher**: Pattern to match tool names, case-sensitive (only applicable for
`PreToolUse` and `PostToolUse`)
- Simple strings match exactly: `Write` matches only the Write tool
- Supports regex: `Edit|Write` or `Notebook.*`
- Use `*` to match all tools. You can also use empty string (`""`) or leave
`matcher` blank.
- **hooks**: Array of commands to execute when the pattern matches
- `type`: Currently only `"command"` is supported
- `command`: The bash command to execute (can use `$CLAUDE_PROJECT_DIR`
environment variable)
- `timeout`: (Optional) How long a command should run, in seconds, before
canceling that specific command.
For events like `UserPromptSubmit`, `Notification`, `Stop`, and `SubagentStop`
that don't use matchers, you can omit the matcher field:
```json
{
"hooks": {
"UserPromptSubmit": [
{
"hooks": [
{
"type": "command",
"command": "/path/to/prompt-validator.py"
}
]
}
]
}
}
```
### Project-Specific Hook Scripts
You can use the environment variable `CLAUDE_PROJECT_DIR` (only available when
Claude Code spawns the hook command) to reference scripts stored in your project,
ensuring they work regardless of Claude's current directory:
```json
{
"hooks": {
"PostToolUse": [
{
"matcher": "Write|Edit",
"hooks": [
{
"type": "command",
"command": "$CLAUDE_PROJECT_DIR/.claude/hooks/check-style.sh"
}
]
}
]
}
}
```
## Hook Events
### PreToolUse
Runs after Claude creates tool parameters and before processing the tool call.
**Common matchers:**
- `Task` - Subagent tasks (see [subagents documentation](/en/docs/claude-code/sub-agents))
- `Bash` - Shell commands
- `Glob` - File pattern matching
- `Grep` - Content search
- `Read` - File reading
- `Edit`, `MultiEdit` - File editing
- `Write` - File writing
- `WebFetch`, `WebSearch` - Web operations
### PostToolUse
Runs immediately after a tool completes successfully.
Recognizes the same matcher values as PreToolUse.
### Notification
Runs when Claude Code sends notifications. Notifications are sent when:
1. Claude needs your permission to use a tool. Example: "Claude needs your
permission to use Bash"
2. The prompt input has been idle for at least 60 seconds. "Claude is waiting
for your input"
### UserPromptSubmit
Runs when the user submits a prompt, before Claude processes it. This allows you
to add additional context based on the prompt/conversation, validate prompts, or
block certain types of prompts.
### Stop
Runs when the main Claude Code agent has finished responding. Does not run if
the stoppage occurred due to a user interrupt.
### SubagentStop
Runs when a Claude Code subagent (Task tool call) has finished responding.
### PreCompact
Runs before Claude Code is about to run a compact operation.
**Matchers:**
- `manual` - Invoked from `/compact`
- `auto` - Invoked from auto-compact (due to full context window)
### SessionStart
Runs when Claude Code starts a new session or resumes an existing session (which
currently does start a new session under the hood). Useful for loading in
development context like existing issues or recent changes to your codebase.
**Matchers:**
- `startup` - Invoked from startup
- `resume` - Invoked from `--resume`, `--continue`, or `/resume`
- `clear` - Invoked from `/clear`
## Hook Input
Hooks receive JSON data via stdin containing session information and
event-specific data:
```typescript
{
// Common fields
session_id: string
transcript_path: string // Path to conversation JSON
cwd: string // The current working directory when the hook is invoked
// Event-specific fields
hook_event_name: string
...
}
```
### PreToolUse Input
The exact schema for `tool_input` depends on the tool.
```json
{
"session_id": "abc123",
"transcript_path": "/Users/.../.claude/projects/.../00893aaf-19fa-41d2-8238-13269b9b3ca0.jsonl",
"cwd": "/Users/...",
"hook_event_name": "PreToolUse",
"tool_name": "Write",
"tool_input": {
"file_path": "/path/to/file.txt",
"content": "file content"
}
}
```
### PostToolUse Input
The exact schema for `tool_input` and `tool_response` depends on the tool.
```json
{
"session_id": "abc123",
"transcript_path": "/Users/.../.claude/projects/.../00893aaf-19fa-41d2-8238-13269b9b3ca0.jsonl",
"cwd": "/Users/...",
"hook_event_name": "PostToolUse",
"tool_name": "Write",
"tool_input": {
"file_path": "/path/to/file.txt",
"content": "file content"
},
"tool_response": {
"filePath": "/path/to/file.txt",
"success": true
}
}
```
### Notification Input
```json
{
"session_id": "abc123",
"transcript_path": "/Users/.../.claude/projects/.../00893aaf-19fa-41d2-8238-13269b9b3ca0.jsonl",
"cwd": "/Users/...",
"hook_event_name": "Notification",
"message": "Task completed successfully"
}
```
### UserPromptSubmit Input
```json
{
"session_id": "abc123",
"transcript_path": "/Users/.../.claude/projects/.../00893aaf-19fa-41d2-8238-13269b9b3ca0.jsonl",
"cwd": "/Users/...",
"hook_event_name": "UserPromptSubmit",
"prompt": "Write a function to calculate the factorial of a number"
}
```
### Stop and SubagentStop Input
`stop_hook_active` is true when Claude Code is already continuing as a result of
a stop hook. Check this value or process the transcript to prevent Claude Code
from running indefinitely.
```json
{
"session_id": "abc123",
"transcript_path": "~/.claude/projects/.../00893aaf-19fa-41d2-8238-13269b9b3ca0.jsonl",
"hook_event_name": "Stop",
"stop_hook_active": true
}
```
### PreCompact Input
For `manual`, `custom_instructions` comes from what the user passes into
`/compact`. For `auto`, `custom_instructions` is empty.
```json
{
"session_id": "abc123",
"transcript_path": "~/.claude/projects/.../00893aaf-19fa-41d2-8238-13269b9b3ca0.jsonl",
"hook_event_name": "PreCompact",
"trigger": "manual",
"custom_instructions": ""
}
```
### SessionStart Input
```json
{
"session_id": "abc123",
"transcript_path": "~/.claude/projects/.../00893aaf-19fa-41d2-8238-13269b9b3ca0.jsonl",
"hook_event_name": "SessionStart",
"source": "startup"
}
```
## Hook Output
There are two ways for hooks to return output back to Claude Code. The output
communicates whether to block and any feedback that should be shown to Claude
and the user.
### Simple: Exit Code
Hooks communicate status through exit codes, stdout, and stderr:
- **Exit code 0**: Success. `stdout` is shown to the user in transcript mode
(CTRL-R), except for `UserPromptSubmit` and `SessionStart`, where stdout is
added to the context.
- **Exit code 2**: Blocking error. `stderr` is fed back to Claude to process
automatically. See per-hook-event behavior below.
- **Other exit codes**: Non-blocking error. `stderr` is shown to the user and
execution continues.
<Warning>
Reminder: Claude Code does not see stdout if the exit code is 0, except for
the `UserPromptSubmit` hook where stdout is injected as context.
</Warning>
#### Exit Code 2 Behavior
| Hook Event | Behavior |
| ------------------ | ------------------------------------------------------------------ |
| `PreToolUse` | Blocks the tool call, shows stderr to Claude |
| `PostToolUse` | Shows stderr to Claude (tool already ran) |
| `Notification` | N/A, shows stderr to user only |
| `UserPromptSubmit` | Blocks prompt processing, erases prompt, shows stderr to user only |
| `Stop` | Blocks stoppage, shows stderr to Claude |
| `SubagentStop` | Blocks stoppage, shows stderr to Claude subagent |
| `PreCompact` | N/A, shows stderr to user only |
| `SessionStart` | N/A, shows stderr to user only |
### Advanced: JSON Output
Hooks can return structured JSON in `stdout` for more sophisticated control:
#### Common JSON Fields
All hook types can include these optional fields:
```json
{
"continue": true, // Whether Claude should continue after hook execution (default: true)
"stopReason": "string" // Message shown when continue is false
"suppressOutput": true, // Hide stdout from transcript mode (default: false)
}
```
If `continue` is false, Claude stops processing after the hooks run.
- For `PreToolUse`, this is different from `"permissionDecision": "deny"`, which
only blocks a specific tool call and provides automatic feedback to Claude.
- For `PostToolUse`, this is different from `"decision": "block"`, which
provides automated feedback to Claude.
- For `UserPromptSubmit`, this prevents the prompt from being processed.
- For `Stop` and `SubagentStop`, this takes precedence over any
`"decision": "block"` output.
- In all cases, `"continue" = false` takes precedence over any
`"decision": "block"` output.
`stopReason` accompanies `continue` with a reason shown to the user, not shown
to Claude.
#### `PreToolUse` Decision Control
`PreToolUse` hooks can control whether a tool call proceeds.
- `"allow"` bypasses the permission system. `permissionDecisionReason` is shown
to the user but not to Claude. (_Deprecated `"approve"` value + `reason` has
the same behavior._)
- `"deny"` prevents the tool call from executing. `permissionDecisionReason` is
shown to Claude. (_`"block"` value + `reason` has the same behavior._)
- `"ask"` asks the user to confirm the tool call in the UI.
`permissionDecisionReason` is shown to the user but not to Claude.
```json
{
"hookSpecificOutput": {
"hookEventName": "PreToolUse",
"permissionDecision": "allow" | "deny" | "ask",
"permissionDecisionReason": "My reason here (shown to user)"
},
"decision": "approve" | "block" | undefined, // Deprecated for PreToolUse but still supported
"reason": "Explanation for decision" // Deprecated for PreToolUse but still supported
}
```
#### `PostToolUse` Decision Control
`PostToolUse` hooks can control whether a tool call proceeds.
- `"block"` automatically prompts Claude with `reason`.
- `undefined` does nothing. `reason` is ignored.
```json
{
"decision": "block" | undefined,
"reason": "Explanation for decision"
}
```
#### `UserPromptSubmit` Decision Control
`UserPromptSubmit` hooks can control whether a user prompt is processed.
- `"block"` prevents the prompt from being processed. The submitted prompt is
erased from context. `"reason"` is shown to the user but not added to context.
- `undefined` allows the prompt to proceed normally. `"reason"` is ignored.
- `"hookSpecificOutput.additionalContext"` adds the string to the context if not
blocked.
```json
{
"decision": "block" | undefined,
"reason": "Explanation for decision",
"hookSpecificOutput": {
"hookEventName": "UserPromptSubmit",
"additionalContext": "My additional context here"
}
}
```
#### `Stop`/`SubagentStop` Decision Control
`Stop` and `SubagentStop` hooks can control whether Claude must continue.
- `"block"` prevents Claude from stopping. You must populate `reason` for Claude
to know how to proceed.
- `undefined` allows Claude to stop. `reason` is ignored.
```json
{
"decision": "block" | undefined,
"reason": "Must be provided when Claude is blocked from stopping"
}
```
#### `SessionStart` Decision Control
`SessionStart` hooks allow you to load in context at the start of a session.
- `"hookSpecificOutput.additionalContext"` adds the string to the context.
```json
{
"hookSpecificOutput": {
"hookEventName": "SessionStart",
"additionalContext": "My additional context here"
}
}
```
#### Exit Code Example: Bash Command Validation
```python
#!/usr/bin/env python3
import json
import re
import sys
# Define validation rules as a list of (regex pattern, message) tuples
VALIDATION_RULES = [
(
r"\bgrep\b(?!.*\|)",
"Use 'rg' (ripgrep) instead of 'grep' for better performance and features",
),
(
r"\bfind\s+\S+\s+-name\b",
"Use 'rg --files | rg pattern' or 'rg --files -g pattern' instead of 'find -name' for better performance",
),
]
def validate_command(command: str) -> list[str]:
issues = []
for pattern, message in VALIDATION_RULES:
if re.search(pattern, command):
issues.append(message)
return issues
try:
input_data = json.load(sys.stdin)
except json.JSONDecodeError as e:
print(f"Error: Invalid JSON input: {e}", file=sys.stderr)
sys.exit(1)
tool_name = input_data.get("tool_name", "")
tool_input = input_data.get("tool_input", {})
command = tool_input.get("command", "")
if tool_name != "Bash" or not command:
sys.exit(1)
# Validate the command
issues = validate_command(command)
if issues:
for message in issues:
print(f"• {message}", file=sys.stderr)
# Exit code 2 blocks tool call and shows stderr to Claude
sys.exit(2)
```
#### JSON Output Example: UserPromptSubmit to Add Context and Validation
<Note>
For `UserPromptSubmit` hooks, you can inject context using either method:
- Exit code 0 with stdout: Claude sees the context (special case for `UserPromptSubmit`)
- JSON output: Provides more control over the behavior
</Note>
```python
#!/usr/bin/env python3
import json
import sys
import re
import datetime
# Load input from stdin
try:
input_data = json.load(sys.stdin)
except json.JSONDecodeError as e:
print(f"Error: Invalid JSON input: {e}", file=sys.stderr)
sys.exit(1)
prompt = input_data.get("prompt", "")
# Check for sensitive patterns
sensitive_patterns = [
(r"(?i)\b(password|secret|key|token)\s*[:=]", "Prompt contains potential secrets"),
]
for pattern, message in sensitive_patterns:
if re.search(pattern, prompt):
# Use JSON output to block with a specific reason
output = {
"decision": "block",
"reason": f"Security policy violation: {message}. Please rephrase your request without sensitive information."
}
print(json.dumps(output))
sys.exit(0)
# Add current time to context
context = f"Current time: {datetime.datetime.now()}"
print(context)
"""
The following is also equivalent:
print(json.dumps({
"hookSpecificOutput": {
"hookEventName": "UserPromptSubmit",
"additionalContext": context,
},
}))
"""
# Allow the prompt to proceed with the additional context
sys.exit(0)
```
#### JSON Output Example: PreToolUse with Approval
```python
#!/usr/bin/env python3
import json
import sys
# Load input from stdin
try:
input_data = json.load(sys.stdin)
except json.JSONDecodeError as e:
print(f"Error: Invalid JSON input: {e}", file=sys.stderr)
sys.exit(1)
tool_name = input_data.get("tool_name", "")
tool_input = input_data.get("tool_input", {})
# Example: Auto-approve file reads for documentation files
if tool_name == "Read":
file_path = tool_input.get("file_path", "")
if file_path.endswith((".md", ".mdx", ".txt", ".json")):
# Use JSON output to auto-approve the tool call
output = {
"decision": "approve",
"reason": "Documentation file auto-approved",
"suppressOutput": True # Don't show in transcript mode
}
print(json.dumps(output))
sys.exit(0)
# For other cases, let the normal permission flow proceed
sys.exit(0)
```
## Working with MCP Tools
Claude Code hooks work seamlessly with
[Model Context Protocol (MCP) tools](/en/docs/claude-code/mcp). When MCP servers
provide tools, they appear with a special naming pattern that you can match in
your hooks.
### MCP Tool Naming
MCP tools follow the pattern `mcp__<server>__<tool>`, for example:
- `mcp__memory__create_entities` - Memory server's create entities tool
- `mcp__filesystem__read_file` - Filesystem server's read file tool
- `mcp__github__search_repositories` - GitHub server's search tool
### Configuring Hooks for MCP Tools
You can target specific MCP tools or entire MCP servers:
```json
{
"hooks": {
"PreToolUse": [
{
"matcher": "mcp__memory__.*",
"hooks": [
{
"type": "command",
"command": "echo 'Memory operation initiated' >> ~/mcp-operations.log"
}
]
},
{
"matcher": "mcp__.*__write.*",
"hooks": [
{
"type": "command",
"command": "/home/user/scripts/validate-mcp-write.py"
}
]
}
]
}
}
```
## Examples

For practical examples including code formatting, notifications, and file protection, see [More Examples](/en/docs/claude-code/hooks-guide#more-examples) in the get started guide.
</Tip>
## Security Considerations
### Disclaimer
**USE AT YOUR OWN RISK**: Claude Code hooks execute arbitrary shell commands on
your system automatically. By using hooks, you acknowledge that:
- You are solely responsible for the commands you configure
- Hooks can modify, delete, or access any files your user account can access
- Malicious or poorly written hooks can cause data loss or system damage
- Anthropic provides no warranty and assumes no liability for any damages
resulting from hook usage
- You should thoroughly test hooks in a safe environment before production use
Always review and understand any hook commands before adding them to your
configuration.
### Security Best Practices
Here are some key practices for writing more secure hooks:
1. **Validate and sanitize inputs** - Never trust input data blindly
2. **Always quote shell variables** - Use `"$VAR"` not `$VAR`
3. **Block path traversal** - Check for `..` in file paths
4. **Use absolute paths** - Specify full paths for scripts (use
`$CLAUDE_PROJECT_DIR` for the project path)
5. **Skip sensitive files** - Avoid `.env`, `.git/`, keys, etc.
### Configuration Safety
Direct edits to hooks in settings files don't take effect immediately. Claude
Code:
1. Captures a snapshot of hooks at startup
2. Uses this snapshot throughout the session
3. Warns if hooks are modified externally
4. Requires review in `/hooks` menu for changes to apply
This prevents malicious hook modifications from affecting your current session.
## Hook Execution Details
- **Timeout**: 60-second execution limit by default, configurable per command.
- A timeout for an individual command does not affect the other commands.
- **Parallelization**: All matching hooks run in parallel
- **Environment**: Runs in current directory with Claude Code's environment
- The `CLAUDE_PROJECT_DIR` environment variable is available and contains the
absolute path to the project root directory
- **Input**: JSON via stdin
- **Output**:
- PreToolUse/PostToolUse/Stop: Progress shown in transcript (Ctrl-R)
- Notification: Logged to debug only (`--debug`)
## Debugging
### Basic Troubleshooting
If your hooks aren't working:
1. **Check configuration** - Run `/hooks` to see if your hook is registered
2. **Verify syntax** - Ensure your JSON settings are valid
3. **Test commands** - Run hook commands manually first
4. **Check permissions** - Make sure scripts are executable
5. **Review logs** - Use `claude --debug` to see hook execution details
Common issues:
- **Quotes not escaped** - Use `\"` inside JSON strings
- **Wrong matcher** - Check tool names match exactly (case-sensitive)
- **Command not found** - Use full paths for scripts
### Advanced Debugging
For complex hook issues:
1. **Inspect hook execution** - Use `claude --debug` to see detailed hook
execution
2. **Validate JSON schemas** - Test hook input/output with external tools
3. **Check environment variables** - Verify Claude Code's environment is correct
4. **Test edge cases** - Try hooks with unusual file paths or inputs
5. **Monitor system resources** - Check for resource exhaustion during hook
execution
6. **Use structured logging** - Implement logging in your hook scripts
### Debug Output Example
Use `claude --debug` to see hook execution details:
```
[DEBUG] Executing hooks for PostToolUse:Write
[DEBUG] Getting matching hook commands for PostToolUse with query: Write
[DEBUG] Found 1 hook matchers in settings
[DEBUG] Matched 1 hooks for query "Write"
[DEBUG] Found 1 hook commands to execute
[DEBUG] Executing hook command: <Your command> with timeout 60000ms
[DEBUG] Hook command completed with status 0: <Your stdout>
```
Progress messages appear in transcript mode (Ctrl-R) showing:
- Which hook is running
- Command being executed
- Success/failure status
- Output or error messages

# Claude Code settings
> Configure Claude Code with global and project-level settings, and environment variables.
Claude Code offers a variety of settings to configure its behavior to meet your needs. You can configure Claude Code by running the `/config` command when using the interactive REPL.
## Settings files
The `settings.json` file is our official mechanism for configuring Claude
Code through hierarchical settings:
- **User settings** are defined in `~/.claude/settings.json` and apply to all
projects.
- **Project settings** are saved in your project directory:
- `.claude/settings.json` for settings that are checked into source control and shared with your team
- `.claude/settings.local.json` for settings that are not checked in, useful for personal preferences and experimentation. Claude Code will configure git to ignore `.claude/settings.local.json` when it is created.
- For enterprise deployments of Claude Code, we also support **enterprise
managed policy settings**. These take precedence over user and project
settings. System administrators can deploy policies to:
- macOS: `/Library/Application Support/ClaudeCode/managed-settings.json`
- Linux and WSL: `/etc/claude-code/managed-settings.json`
- Windows: `C:\ProgramData\ClaudeCode\managed-settings.json`
```JSON Example settings.json
{
"permissions": {
"allow": [
"Bash(npm run lint)",
"Bash(npm run test:*)",
"Read(~/.zshrc)"
],
"deny": [
"Bash(curl:*)",
"Read(./.env)",
"Read(./.env.*)",
"Read(./secrets/**)"
]
},
"env": {
"CLAUDE_CODE_ENABLE_TELEMETRY": "1",
"OTEL_METRICS_EXPORTER": "otlp"
}
}
```
### Available settings
`settings.json` supports a number of options:
| Key | Description | Example |
| :--------------------------- | :-------------------------------------------------------------------------------------------------------------------------------------------------------------------- | :---------------------------------------------------------- |
| `apiKeyHelper` | Custom script, to be executed in `/bin/sh`, to generate an auth value. This value will be sent as `X-Api-Key` and `Authorization: Bearer` headers for model requests | `/bin/generate_temp_api_key.sh` |
| `cleanupPeriodDays` | How long to locally retain chat transcripts based on last activity date (default: 30 days) | `20` |
| `env` | Environment variables that will be applied to every session | `{"FOO": "bar"}` |
| `includeCoAuthoredBy` | Whether to include the `co-authored-by Claude` byline in git commits and pull requests (default: `true`) | `false` |
| `permissions` | See table below for structure of permissions. | |
| `hooks` | Configure custom commands to run before or after tool executions. See [hooks documentation](hooks) | `{"PreToolUse": {"Bash": "echo 'Running command...'"}}` |
| `model` | Override the default model to use for Claude Code | `"claude-3-5-sonnet-20241022"` |
| `statusLine` | Configure a custom status line to display context. See [statusLine documentation](statusline) | `{"type": "command", "command": "~/.claude/statusline.sh"}` |
| `forceLoginMethod` | Use `claudeai` to restrict login to Claude.ai accounts, `console` to restrict login to Anthropic Console (API usage billing) accounts | `claudeai` |
| `enableAllProjectMcpServers` | Automatically approve all MCP servers defined in project `.mcp.json` files | `true` |
| `enabledMcpjsonServers` | List of specific MCP servers from `.mcp.json` files to approve | `["memory", "github"]` |
| `disabledMcpjsonServers` | List of specific MCP servers from `.mcp.json` files to reject | `["filesystem"]` |
| `awsAuthRefresh` | Custom script that modifies the `.aws` directory (see [advanced credential configuration](/en/docs/claude-code/amazon-bedrock#advanced-credential-configuration)) | `aws sso login --profile myprofile` |
| `awsCredentialExport` | Custom script that outputs JSON with AWS credentials (see [advanced credential configuration](/en/docs/claude-code/amazon-bedrock#advanced-credential-configuration)) | `/bin/generate_aws_grant.sh` |
### Permission settings
| Keys | Description | Example |
| :----------------------------- | :---------------------------------------------------------------------------------------------------------------------------------------------------------------- | :--------------------------------------------------------------------- |
| `allow` | Array of [permission rules](/en/docs/claude-code/iam#configuring-permissions) to allow tool use | `[ "Bash(git diff:*)" ]` |
| `ask` | Array of [permission rules](/en/docs/claude-code/iam#configuring-permissions) to ask for confirmation upon tool use. | `[ "Bash(git push:*)" ]` |
| `deny` | Array of [permission rules](/en/docs/claude-code/iam#configuring-permissions) to deny tool use. Use this to also exclude sensitive files from Claude Code access. | `[ "WebFetch", "Bash(curl:*)", "Read(./.env)", "Read(./secrets/**)" ]` |
| `additionalDirectories` | Additional [working directories](iam#working-directories) that Claude has access to | `[ "../docs/" ]` |
| `defaultMode` | Default [permission mode](iam#permission-modes) when opening Claude Code | `"acceptEdits"` |
| `disableBypassPermissionsMode` | Set to `"disable"` to prevent `bypassPermissions` mode from being activated. See [managed policy settings](iam#enterprise-managed-policy-settings) | `"disable"` |
### Settings precedence
Settings are applied in order of precedence (highest to lowest):
1. **Enterprise managed policies** (`managed-settings.json`)
- Deployed by IT/DevOps
- Cannot be overridden
2. **Command line arguments**
- Temporary overrides for a specific session
3. **Local project settings** (`.claude/settings.local.json`)
- Personal project-specific settings
4. **Shared project settings** (`.claude/settings.json`)
- Team-shared project settings in source control
5. **User settings** (`~/.claude/settings.json`)
- Personal global settings
This hierarchy ensures that enterprise security policies are always enforced while still allowing teams and individuals to customize their experience.
### Key points about the configuration system
- **Memory files (CLAUDE.md)**: Contain instructions and context that Claude loads at startup
- **Settings files (JSON)**: Configure permissions, environment variables, and tool behavior
- **Slash commands**: Custom commands that can be invoked during a session with `/command-name`
- **MCP servers**: Extend Claude Code with additional tools and integrations
- **Precedence**: Higher-level configurations (Enterprise) override lower-level ones (User/Project)
- **Inheritance**: Settings are merged, with more specific settings adding to or overriding broader ones
### System prompt availability
<Note>
Unlike for claude.ai, we do not publish Claude Code's internal system prompt on this website. Use CLAUDE.md files or `--append-system-prompt` to add custom instructions to Claude Code's behavior.
</Note>
### Excluding sensitive files
To prevent Claude Code from accessing files containing sensitive information (e.g., API keys, secrets, environment files), use the `permissions.deny` setting in your `.claude/settings.json` file:
```json
{
"permissions": {
"deny": [
"Read(./.env)",
"Read(./.env.*)",
"Read(./secrets/**)",
"Read(./config/credentials.json)",
"Read(./build)"
]
}
}
```
This replaces the deprecated `ignorePatterns` configuration. Files matching these patterns will be completely invisible to Claude Code, preventing any accidental exposure of sensitive data.
## Subagent configuration
Claude Code supports custom AI subagents that can be configured at both user and project levels. These subagents are stored as Markdown files with YAML frontmatter:
- **User subagents**: `~/.claude/agents/` - Available across all your projects
- **Project subagents**: `.claude/agents/` - Specific to your project and can be shared with your team
Subagent files define specialized AI assistants with custom prompts and tool permissions. Learn more about creating and using subagents in the [subagents documentation](/en/docs/claude-code/sub-agents).
## Environment variables
Claude Code supports the following environment variables to control its behavior:
<Note>
All environment variables can also be configured in [`settings.json`](#available-settings). This is useful as a way to automatically set environment variables for each session, or to roll out a set of environment variables for your whole team or organization.
</Note>

## Configuration options
To manage your configurations, use the following commands:
- List settings: `claude config list`
- See a setting: `claude config get <key>`
- Change a setting: `claude config set <key> <value>`
- Push to a setting (for lists): `claude config add <key> <value>`
- Remove from a setting (for lists): `claude config remove <key> <value>`
By default `config` changes your project configuration. To manage your global configuration, use the `--global` (or `-g`) flag.
### Global configuration
To set a global configuration, use `claude config set -g <key> <value>`:
| Key | Description | Example |
| :---------------------- | :------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | :------------------------------------------------------------------------- |
| `autoUpdates` | Whether to enable automatic updates (default: `true`). When enabled, Claude Code automatically downloads and installs updates in the background. Updates are applied when you restart Claude Code. | `false` |
| `preferredNotifChannel` | Where you want to receive notifications (default: `iterm2`) | `iterm2`, `iterm2_with_bell`, `terminal_bell`, or `notifications_disabled` |
| `theme` | Color theme | `dark`, `light`, `light-daltonized`, or `dark-daltonized` |
| `verbose` | Whether to show full bash and command outputs (default: `false`) | `true` |
## Tools available to Claude
Claude Code has access to a set of powerful tools that help it understand and modify your codebase:
| Tool | Description | Permission Required |
| :--------------- | :--------------------------------------------------- | :------------------ |
| **Bash** | Executes shell commands in your environment | Yes |
| **Edit** | Makes targeted edits to specific files | Yes |
| **Glob** | Finds files based on pattern matching | No |
| **Grep** | Searches for patterns in file contents | No |
| **LS** | Lists files and directories | No |
| **MultiEdit** | Performs multiple edits on a single file atomically | Yes |

Permission rules can be configured using `/allowed-tools` or in [permission settings](/en/docs/claude-code/settings#available-settings).
### Extending tools with hooks
You can run custom commands before or after any tool executes using
[Claude Code hooks](/en/docs/claude-code/hooks-guide).
For example, you could automatically run a Python formatter after Claude
modifies Python files, or prevent modifications to production configuration
files by blocking Write operations to certain paths.

| `/terminal-setup` | Install Shift+Enter key binding for newlines (iTerm2 and VSCode only) |
| `/vim` | Enter vim mode for alternating insert and command modes |
## Custom slash commands
Custom slash commands allow you to define frequently-used prompts as Markdown files that Claude Code can execute. Commands are organized by scope (project-specific or personal) and support namespacing through directory structures.
### Syntax
```
/<command-name> [arguments]
```
#### Parameters
| Parameter | Description |
| :--------------- | :---------------------------------------------------------------- |
| `<command-name>` | Name derived from the Markdown filename (without `.md` extension) |
| `[arguments]` | Optional arguments passed to the command |
### Command types
#### Project commands
Commands stored in your repository and shared with your team. When listed in `/help`, these commands show "(project)" after their description.
**Location**: `.claude/commands/`
In the following example, we create the `/optimize` command:
```bash
# Create a project command
mkdir -p .claude/commands
echo "Analyze this code for performance issues and suggest optimizations:" > .claude/commands/optimize.md
```
#### Personal commands
Commands available across all your projects. When listed in `/help`, these commands show "(user)" after their description.
**Location**: `~/.claude/commands/`
In the following example, we create the `/security-review` command:
```bash
# Create a personal command
mkdir -p ~/.claude/commands
echo "Review this code for security vulnerabilities:" > ~/.claude/commands/security-review.md
```
### Features
#### Namespacing
Organize commands in subdirectories. The subdirectories are used for organization and appear in the command description, but they do not affect the command name itself. The description will show whether the command comes from the project directory (`.claude/commands`) or the user-level directory (`~/.claude/commands`), along with the subdirectory name.
Conflicts between user and project level commands are not supported. Otherwise, multiple commands with the same base file name can coexist.
For example, a file at `.claude/commands/frontend/component.md` creates the command `/component` with description showing "(project:frontend)".
Meanwhile, a file at `~/.claude/commands/component.md` creates the command `/component` with description showing "(user)".
#### Arguments
Pass dynamic values to commands using the `$ARGUMENTS` placeholder.
For example:
```bash
# Command definition
echo 'Fix issue #$ARGUMENTS following our coding standards' > .claude/commands/fix-issue.md
# Usage
> /fix-issue 123
```
#### Bash command execution
Execute bash commands before the slash command runs using the `!` prefix. The output is included in the command context. You _must_ include `allowed-tools` with the `Bash` tool, but you can choose the specific bash commands to allow.
For example:
```markdown
---
allowed-tools: Bash(git add:*), Bash(git status:*), Bash(git commit:*)
description: Create a git commit
---
## Context
- Current git status: !`git status`
- Current git diff (staged and unstaged changes): !`git diff HEAD`
- Current branch: !`git branch --show-current`
- Recent commits: !`git log --oneline -10`
## Your task
Based on the above changes, create a single git commit.
```
#### File references
Include file contents in commands using the `@` prefix to [reference files](/en/docs/claude-code/common-workflows#reference-files-and-directories).
For example:
```markdown
# Reference a specific file
Review the implementation in @src/utils/helpers.js
# Reference multiple files
Compare @src/old-version.js with @src/new-version.js
```
#### Thinking mode
Slash commands can trigger extended thinking by including [extended thinking keywords](/en/docs/claude-code/common-workflows#use-extended-thinking).
### Frontmatter
Command files support frontmatter, useful for specifying metadata about the command:
| Frontmatter | Purpose | Default |
| :-------------- | :------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | :---------------------------------- |
| `allowed-tools` | List of tools the command can use | Inherits from the conversation |
| `argument-hint` | The arguments expected for the slash command. Example: `argument-hint: add [tagId] \| remove [tagId] \| list`. This hint is shown to the user when auto-completing the slash command. | None |
| `description` | Brief description of the command | Uses the first line from the prompt |
| `model` | Specific model string (see [Models overview](/en/docs/about-claude/models/overview)) | Inherits from the conversation |
For example:
```markdown
---
allowed-tools: Bash(git add:*), Bash(git status:*), Bash(git commit:*)
argument-hint: [message]
description: Create a git commit
model: claude-3-5-haiku-20241022
---
An example command
```
## MCP slash commands
MCP servers can expose prompts as slash commands that become available in Claude Code. These commands are dynamically discovered from connected MCP servers.
### Command format
MCP commands follow the pattern:
```
/mcp__<server-name>__<prompt-name> [arguments]
```
### Features
#### Dynamic discovery
MCP commands are automatically available when:
- An MCP server is connected and active
- The server exposes prompts through the MCP protocol
- The prompts are successfully retrieved during connection
#### Arguments
MCP prompts can accept arguments defined by the server:
```
# Without arguments
> /mcp__github__list_prs
# With arguments
> /mcp__github__pr_review 456
> /mcp__jira__create_issue "Bug title" high
```
#### Naming conventions
- Server and prompt names are normalized
- Spaces and special characters become underscores
- Names are lowercased for consistency
### Managing MCP connections
Use the `/mcp` command to:
- View all configured MCP servers
- Check connection status
- Authenticate with OAuth-enabled servers
- Clear authentication tokens
- View available tools and prompts from each server

# Output styles
> Adapt Claude Code for uses beyond software engineering
Output styles allow you to use Claude Code as any type of agent while keeping
its core capabilities, such as running local scripts, reading/writing files, and
tracking TODOs.
## Built-in output styles
Claude Code's **Default** output style is the existing system prompt, designed
to help you complete software engineering tasks efficiently.
There are two additional built-in output styles focused on teaching you the
codebase and how Claude operates:
- **Explanatory**: Provides educational "Insights" in between helping you
complete software engineering tasks. Helps you understand implementation
choices and codebase patterns.
- **Learning**: Collaborative, learn-by-doing mode where Claude will not only
share "Insights" while coding, but also ask you to contribute small, strategic
pieces of code yourself. Claude Code will add `TODO(human)` markers in your
code for you to implement.
## How output styles work
Output styles directly modify Claude Code's system prompt.
- Non-default output styles exclude instructions specific to code generation and
efficient output normally built into Claude Code (such as responding concisely
and verifying code with tests).
- Instead, these output styles have their own custom instructions added to the
system prompt.
## Change your output style
You can either:
- Run `/output-style` to access the menu and select your output style (this can
also be accessed from the `/config` menu)
- Run `/output-style [style]`, such as `/output-style explanatory`, to directly
switch to a style
These changes apply to the [local project level](/en/docs/claude-code/settings)
and are saved in `.claude/settings.local.json`.
## Create a custom output style
To set up a new output style with Claude's help, run
`/output-style:new I want an output style that ...`
By default, output styles created through `/output-style:new` are saved as
markdown files at the user level in `~/.claude/output-styles` and can be used
across projects. They have the following structure:
```markdown
---
name: My Custom Style
description: A brief description of what this style does, to be displayed to the user
---
# Custom Style Instructions
You are an interactive CLI tool that helps users with software engineering
tasks. [Your custom instructions here...]
## Specific Behaviors
[Define how the assistant should behave in this style...]
```
You can also create your own output style Markdown files and save them either at
the user level (`~/.claude/output-styles`) or the project level
(`.claude/output-styles`).
## Comparisons to related features
### Output Styles vs. CLAUDE.md vs. --append-system-prompt
Output styles completely “turn off” the parts of Claude Codes default system
prompt specific to software engineering. Neither CLAUDE.md nor
`--append-system-prompt` edit Claude Codes default system prompt. CLAUDE.md
adds the contents as a user message _following_ Claude Codes default system
prompt. `--append-system-prompt` appends the content to the system prompt.
### Output Styles vs. [Agents](/en/docs/claude-code/sub-agents)
Output styles directly affect the main agent loop and only affect the system
prompt. Agents are invoked to handle specific tasks and can include additional
settings like the model to use, the tools they have available, and some context
about when to use the agent.
### Output Styles vs. [Custom Slash Commands](/en/docs/claude-code/slash-commands)
You can think of output styles as “stored system prompts” and custom slash
commands as “stored prompts”.

# Subagents
> Create and use specialized AI subagents in Claude Code for task-specific workflows and improved context management.
Custom subagents in Claude Code are specialized AI assistants that can be invoked to handle specific types of tasks. They enable more efficient problem-solving by providing task-specific configurations with customized system prompts, tools and a separate context window.
## What are subagents?
Subagents are pre-configured AI personalities that Claude Code can delegate tasks to. Each subagent:
- Has a specific purpose and expertise area
- Uses its own context window separate from the main conversation
- Can be configured with specific tools it's allowed to use
- Includes a custom system prompt that guides its behavior
When Claude Code encounters a task that matches a subagent's expertise, it can delegate that task to the specialized subagent, which works independently and returns results.
## Key benefits
<CardGroup cols={2}>
<Card title="Context preservation" icon="layer-group">
Each subagent operates in its own context, preventing pollution of the main conversation and keeping it focused on high-level objectives.
</Card>
<Card title="Specialized expertise" icon="brain">
Subagents can be fine-tuned with detailed instructions for specific domains, leading to higher success rates on designated tasks.
</Card>
<Card title="Reusability" icon="rotate">
Once created, subagents can be used across different projects and shared with your team for consistent workflows.
</Card>
<Card title="Flexible permissions" icon="shield-check">
Each subagent can have different tool access levels, allowing you to limit powerful tools to specific subagent types.
</Card>
</CardGroup>
## Quick start
To create your first subagent:
<Steps>
<Step title="Open the subagents interface">
Run the following command:
```
/agents
```
</Step>
<Step title="Select 'Create New Agent'">
Choose whether to create a project-level or user-level subagent
</Step>
<Step title="Define the subagent">
* **Recommended**: Generate with Claude first, then customize to make it yours
* Describe your subagent in detail and when it should be used
* Select the tools you want to grant access to (or leave blank to inherit all tools)
* The interface shows all available tools, making selection easy
* If you're generating with Claude, you can also edit the system prompt in your own editor by pressing `e`
</Step>
<Step title="Save and use">
Your subagent is now available! Claude will use it automatically when appropriate, or you can invoke it explicitly:
```
> Use the code-reviewer subagent to check my recent changes
```
</Step>
</Steps>
## Subagent configuration
### File locations
Subagents are stored as Markdown files with YAML frontmatter in two possible locations:
| Type | Location | Scope | Priority |
| :-------------------- | :------------------ | :---------------------------- | :------- |
| **Project subagents** | `.claude/agents/` | Available in current project | Highest |
| **User subagents** | `~/.claude/agents/` | Available across all projects | Lower |
When subagent names conflict, project-level subagents take precedence over user-level subagents.
### File format
Each subagent is defined in a Markdown file with this structure:
```markdown
---
name: your-sub-agent-name
description: Description of when this subagent should be invoked
tools: tool1, tool2, tool3 # Optional - inherits all tools if omitted
---
Your subagent's system prompt goes here. This can be multiple paragraphs
and should clearly define the subagent's role, capabilities, and approach
to solving problems.
Include specific instructions, best practices, and any constraints
the subagent should follow.
```
#### Configuration fields
| Field | Required | Description |
| :------------ | :------- | :------------------------------------------------------------------------------------------ |
| `name` | Yes | Unique identifier using lowercase letters and hyphens |
| `description` | Yes | Natural language description of the subagent's purpose |
| `tools` | No | Comma-separated list of specific tools. If omitted, inherits all tools from the main thread |
### Available tools
Subagents can be granted access to any of Claude Code's internal tools. See the [tools documentation](/en/docs/claude-code/settings#tools-available-to-claude) for a complete list of available tools.
<Tip>
**Recommended:** Use the `/agents` command to modify tool access - it provides an interactive interface that lists all available tools, including any connected MCP server tools, making it easier to select the ones you need.
</Tip>
You have two options for configuring tools:
- **Omit the `tools` field** to inherit all tools from the main thread (default), including MCP tools
- **Specify individual tools** as a comma-separated list for more granular control (can be edited manually or via `/agents`)
**MCP Tools**: Subagents can access MCP tools from configured MCP servers. When the `tools` field is omitted, subagents inherit all MCP tools available to the main thread.
## Managing subagents
### Using the /agents command (Recommended)
The `/agents` command provides a comprehensive interface for subagent management:
```
/agents
```
This opens an interactive menu where you can:
- View all available subagents (built-in, user, and project)
- Create new subagents with guided setup
- Edit existing custom subagents, including their tool access
- Delete custom subagents
- See which subagents are active when duplicates exist
- **Easily manage tool permissions** with a complete list of available tools
### Direct file management
You can also manage subagents by working directly with their files:
```bash
# Create a project subagent
mkdir -p .claude/agents
echo '---
name: test-runner
description: Use proactively to run tests and fix failures
---
You are a test automation expert. When you see code changes, proactively run the appropriate tests. If tests fail, analyze the failures and fix them while preserving the original test intent.' > .claude/agents/test-runner.md
# Create a user subagent
mkdir -p ~/.claude/agents
# ... create subagent file
```
## Using subagents effectively
### Automatic delegation
Claude Code proactively delegates tasks based on:
- The task description in your request
- The `description` field in subagent configurations
- Current context and available tools
<Tip>
To encourage more proactive subagent use, include phrases like "use PROACTIVELY" or "MUST BE USED" in your `description` field.
</Tip>
### Explicit invocation
Request a specific subagent by mentioning it in your command:
```
> Use the test-runner subagent to fix failing tests
> Have the code-reviewer subagent look at my recent changes
> Ask the debugger subagent to investigate this error
```
## Example subagents
### Code reviewer
```markdown
---
name: code-reviewer
description: Expert code review specialist. Proactively reviews code for quality, security, and maintainability. Use immediately after writing or modifying code.
tools: Read, Grep, Glob, Bash
---
You are a senior code reviewer ensuring high standards of code quality and security.
When invoked:
1. Run git diff to see recent changes
2. Focus on modified files
3. Begin review immediately
Review checklist:
- Code is simple and readable
- Functions and variables are well-named
- No duplicated code
- Proper error handling
- No exposed secrets or API keys
- Input validation implemented
- Good test coverage
- Performance considerations addressed
Provide feedback organized by priority:
- Critical issues (must fix)
- Warnings (should fix)
- Suggestions (consider improving)
Include specific examples of how to fix issues.
```
### Debugger
```markdown
---
name: debugger
description: Debugging specialist for errors, test failures, and unexpected behavior. Use proactively when encountering any issues.
tools: Read, Edit, Bash, Grep, Glob
---
You are an expert debugger specializing in root cause analysis.
When invoked:
1. Capture error message and stack trace
2. Identify reproduction steps
3. Isolate the failure location
4. Implement minimal fix
5. Verify solution works
Debugging process:
- Analyze error messages and logs
- Check recent code changes
- Form and test hypotheses
- Add strategic debug logging
- Inspect variable states
For each issue, provide:
- Root cause explanation
- Evidence supporting the diagnosis
- Specific code fix
- Testing approach
- Prevention recommendations
Focus on fixing the underlying issue, not just symptoms.
```
### Data scientist
```markdown
---
name: data-scientist
description: Data analysis expert for SQL queries, BigQuery operations, and data insights. Use proactively for data analysis tasks and queries.
tools: Bash, Read, Write
---
You are a data scientist specializing in SQL and BigQuery analysis.
When invoked:
1. Understand the data analysis requirement
2. Write efficient SQL queries
3. Use BigQuery command line tools (bq) when appropriate
4. Analyze and summarize results
5. Present findings clearly
Key practices:
- Write optimized SQL queries with proper filters
- Use appropriate aggregations and joins
- Include comments explaining complex logic
- Format results for readability
- Provide data-driven recommendations
For each analysis:
- Explain the query approach
- Document any assumptions
- Highlight key findings
- Suggest next steps based on data
Always ensure queries are efficient and cost-effective.
```
## Best practices
- **Start with Claude-generated agents**: We highly recommend generating your initial subagent with Claude and then iterating on it to make it personally yours. This approach gives you the best results - a solid foundation that you can customize to your specific needs.
- **Design focused subagents**: Create subagents with single, clear responsibilities rather than trying to make one subagent do everything. This improves performance and makes subagents more predictable.
- **Write detailed prompts**: Include specific instructions, examples, and constraints in your system prompts. The more guidance you provide, the better the subagent will perform.
- **Limit tool access**: Only grant tools that are necessary for the subagent's purpose. This improves security and helps the subagent focus on relevant actions.
- **Version control**: Check project subagents into version control so your team can benefit from and improve them collaboratively.
## Advanced usage
### Chaining subagents
For complex workflows, you can chain multiple subagents:
```
> First use the code-analyzer subagent to find performance issues, then use the optimizer subagent to fix them
```
### Dynamic subagent selection
Claude Code intelligently selects subagents based on context. Make your `description` fields specific and action-oriented for best results.
## Performance considerations
- **Context efficiency**: Agents help preserve main context, enabling longer overall sessions
- **Latency**: Subagents start off with a clean slate each time they are invoked and may add latency as they gather context that they require to do their job effectively.

# Claude Code Documentation Context
This directory contains documentation pages from [Anthropic's Claude Code documentation](https://docs.anthropic.com/) that have been downloaded for AI context and reference.
## Purpose
These files serve as authoritative documentation for Claude Code features, allowing AI assistants to provide accurate information about Claude Code capabilities, settings, and usage patterns without needing to access the web for common queries.
## File Naming Convention
Files are named based on their URL path from the docs site:
- URL: `https://docs.anthropic.com/en/docs/claude-code/settings#tools-available-to-claude`
- Filename: `CLAUDE_CODE_SETTINGS.md`
The naming follows these rules:
- Convert path segments to uppercase
- Replace `/` with `_`
- Remove language prefixes (`/en/docs/`)
- Ignore URL anchors (the `#` portion)
- Use `.md` extension
## How to Add New Documentation
1. Navigate to the desired page on https://docs.anthropic.com/
2. Click the "Copy page" button in the top right corner
3. Select "Copy page as Markdown for LLMs"
4. Create a new file in this directory following the naming convention
5. Paste the copied content into the file
## For AI Assistants
When using these files:
- Treat content as current, valid Claude Code documentation
- All relative URLs in the files are relative to `https://docs.anthropic.com/`
- If you encounter a relative link to documentation not yet downloaded:
1. First check if the file exists using the naming convention above
2. If not found, attempt to retrieve using available tools
**Note to AI:** Please update this section with the most effective method for retrieving missing documentation pages (web fetch tools vs browser-use MCP server) once you've determined which works best through testing.
## Maintenance
Periodically check for updates to the documentation on the Anthropic site, as these local copies may become outdated. The "Copy page" feature ensures we get the most LLM-friendly format of the documentation.

# AI Working Directory
The purpose of this directory is to provide a working space for AI-tools to create, modify, and execute plans for implementing changes in a project. It serves as a collaborative space where AI can generate plans, execute them, and document the process for future reference.
This directory name was chosen instead of a dot-prefixed name to allow it to be easily referenced inside AI-tools that otherwise ignore dot-prefixed directories, such as Claude Code.
For temporary files that you do not want checked in, use the `tmp` subdirectory.
This allows for a choice between storing files in a version-controlled manner (for lifetime of branch and clearing before PR, or longer lived if needed) or keeping them temporary and not checked in.

- [Monitoring](./guides/monitoring.md)
- [Making backups](./guides/making-backups.md)
- [Restoring backups](./guides/restoring-backups.md)
## Upgrade
- [Upgrade applications](./guides/upgrade-applications.md)
- [Upgrade kubernetes](./guides/upgrade-kubernetes.md)
- [Upgrade Talos](./guides/upgrade-talos.md)
- [Upgrade Wild Cloud](./guides/upgrade-wild-cloud.md)
This guide covers essential maintenance tasks for your personal cloud infrastructure, including troubleshooting, backups, updates, and security best practices.
## Troubleshooting
- [Cluster issues](./guides/troubleshoot-cluster.md)
- [DNS issues](./guides/troubleshoot-dns.md)
- [Service connectivity issues](./guides/troubleshoot-service-connectivity.md)
- [TLS certificate issues](./guides/troubleshoot-tls-certificates.md)
- [Visibility issues](./guides/troubleshoot-visibility.md)
### General Troubleshooting Steps
1. **Check Component Status**:
```bash
# Check all pods across all namespaces
kubectl get pods -A
# Look for pods that aren't Running or Ready
kubectl get pods -A | grep -v "Running\|Completed"
```
2. **View Detailed Pod Information**:
```bash
# Get detailed info about problematic pods
kubectl describe pod <pod-name> -n <namespace>
# Check pod logs
kubectl logs <pod-name> -n <namespace>
```
3. **Run Validation Script**:
```bash
./infrastructure_setup/validate_setup.sh
```
4. **Check Node Status**:
```bash
kubectl get nodes
kubectl describe node <node-name>
```
### Common Issues
#### Certificate Problems
If services show invalid certificates:
1. Check certificate status:
```bash
kubectl get certificates -A
```
2. Examine certificate details:
```bash
kubectl describe certificate <cert-name> -n <namespace>
```
3. Check for cert-manager issues:
```bash
kubectl get pods -n cert-manager
kubectl logs -l app=cert-manager -n cert-manager
```
4. Verify the Cloudflare API token is correctly set up:
```bash
kubectl get secret cloudflare-api-token -n internal
```
#### DNS Issues
If DNS resolution isn't working properly:
1. Check CoreDNS status:
```bash
kubectl get pods -n kube-system -l k8s-app=kube-dns
kubectl logs -l k8s-app=kube-dns -n kube-system
```
2. Verify CoreDNS configuration:
```bash
kubectl get configmap -n kube-system coredns -o yaml
```
3. Test DNS resolution from inside the cluster:
```bash
kubectl run -i --tty --rm debug --image=busybox --restart=Never -- nslookup kubernetes.default
```
#### Service Connectivity
If services can't communicate:
1. Check network policies:
```bash
kubectl get networkpolicies -A
```
2. Verify service endpoints:
```bash
kubectl get endpoints -n <namespace>
```
3. Test connectivity from within the cluster:
```bash
kubectl run -i --tty --rm debug --image=busybox --restart=Never -- wget -O- <service-name>.<namespace>
```
## Backup and Restore
### What to Back Up
1. **Persistent Data**:
- Database volumes
- Application storage
- Configuration files
2. **Kubernetes Resources**:
- Custom Resource Definitions (CRDs)
- Deployments, Services, Ingresses
- Secrets and ConfigMaps
### Backup Methods
#### Simple Backup Script
Create a backup script at `bin/backup.sh` (to be implemented):
```bash
#!/bin/bash
# Simple backup script for your personal cloud
# This is a placeholder for future implementation
BACKUP_DIR="/path/to/backups/$(date +%Y-%m-%d)"
mkdir -p "$BACKUP_DIR"
# Back up Kubernetes resources
kubectl get all -A -o yaml > "$BACKUP_DIR/all-resources.yaml"
kubectl get secrets -A -o yaml > "$BACKUP_DIR/secrets.yaml"
kubectl get configmaps -A -o yaml > "$BACKUP_DIR/configmaps.yaml"
# Back up persistent volumes
# TODO: Add logic to back up persistent volume data
echo "Backup completed: $BACKUP_DIR"
```
#### Using Velero (Recommended for Future)
[Velero](https://velero.io/) is a powerful backup solution for Kubernetes:
```bash
# Install Velero (future implementation)
helm repo add vmware-tanzu https://vmware-tanzu.github.io/helm-charts
helm install velero vmware-tanzu/velero --namespace velero --create-namespace
# Create a backup
velero backup create my-backup --include-namespaces default,internal
# Restore from backup
velero restore create --from-backup my-backup
```
### Database Backups
For database services, set up regular dumps:
```bash
# PostgreSQL backup (placeholder)
kubectl exec <postgres-pod> -n <namespace> -- pg_dump -U <username> <database> > backup.sql
# MariaDB/MySQL backup (placeholder)
kubectl exec <mariadb-pod> -n <namespace> -- mysqldump -u root -p<password> <database> > backup.sql
```
## Updates
### Updating Kubernetes (K3s)
1. Check current version:
```bash
k3s --version
```
2. Update K3s:
```bash
curl -sfL https://get.k3s.io | sh -
```
3. Verify the update:
```bash
k3s --version
kubectl get nodes
```
### Updating Infrastructure Components
1. Update the repository:
```bash
git pull
```
2. Re-run the setup script:
```bash
./infrastructure_setup/setup-all.sh
```
3. Or update specific components:
```bash
./infrastructure_setup/setup-cert-manager.sh
./infrastructure_setup/setup-dashboard.sh
# etc.
```
### Updating Applications
For Helm chart applications:
```bash
# Update Helm repositories
helm repo update
# Upgrade a specific application
./bin/helm-install <chart-name> --upgrade
```
For services deployed with `deploy-service`:
```bash
# Edit the service YAML
nano services/<service-name>/service.yaml
# Apply changes
kubectl apply -f services/<service-name>/service.yaml
```
## Security
### Best Practices
1. **Keep Everything Updated**:
- Regularly update K3s
- Update all infrastructure components
- Keep application images up to date
2. **Network Security**:
- Use internal services whenever possible
- Limit exposed services to only what's necessary
- Configure your home router's firewall properly
3. **Access Control**:
- Use strong passwords for all services
- Implement a secrets management strategy
- Rotate API tokens and keys regularly
4. **Regular Audits**:
- Review running services periodically
- Check for unused or outdated deployments
- Monitor resource usage for anomalies
### Security Scanning (Future Implementation)
Tools to consider implementing:
1. **Trivy** for image scanning:
```bash
# Example Trivy usage (placeholder)
trivy image <your-image>
```
2. **kube-bench** for Kubernetes security checks:
```bash
# Example kube-bench usage (placeholder)
kubectl apply -f https://raw.githubusercontent.com/aquasecurity/kube-bench/main/job.yaml
```
3. **Falco** for runtime security monitoring:
```bash
# Example Falco installation (placeholder)
helm repo add falcosecurity https://falcosecurity.github.io/charts
helm install falco falcosecurity/falco --namespace falco --create-namespace
```
## System Health Monitoring
### Basic Monitoring
Check system health with:
```bash
# Node resource usage
kubectl top nodes
# Pod resource usage
kubectl top pods -A
# Persistent volume claims
kubectl get pvc -A
```
### Advanced Monitoring (Future Implementation)
Consider implementing:
1. **Prometheus + Grafana** for comprehensive monitoring:
```bash
# Placeholder for future implementation
helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
helm install prometheus prometheus-community/kube-prometheus-stack --namespace monitoring --create-namespace
```
2. **Loki** for log aggregation:
```bash
# Placeholder for future implementation
helm repo add grafana https://grafana.github.io/helm-charts
helm install loki grafana/loki-stack --namespace logging --create-namespace
```

# Wild Cloud Setup
## Hardware prerequisites
Procure the following before setup:
- Any machine for running setup and managing your cloud.
- One small machine for dnsmasq (running Ubuntu linux)
- Three machines for control nodes (2GB memory, 100GB hard drive).
- Any number of worker node machines.
- A network switch connecting all these machines to your router.
- A network router (e.g. Fluke 2) connected to the Internet.
- A domain of your choice registerd (or managed) on Cloudflare.
## Setup
Clone this repo (you probably already did this).
```bash
source env.sh
```
Initialize a personal wild-cloud in any empty directory, for example:
```bash
cd ~
mkdir ~/my-wild-cloud
cd my-wild-cloud
wild-setup-scaffold
```
## Download Cluster Node Boot Assets
We use Talos linux for node operating systems. Run this script to download the OS for use in the rest of the setup.
```bash
# Generate node boot assets (PXE, iPXE, ISO)
wild-cluster-node-boot-assets-download
```
## Dnsmasq
- Install a Linux machine on your LAN. Record it's IP address in your `config:cloud.dns.ip`.
- Ensure it is accessible with ssh.
```bash
# Install dnsmasq with PXE boot support
wild-dnsmasq-install --install
```
## Cluster Setup
### Cluster Infrastructure Setup
```bash
# Configure network, cluster settings, and register nodes
wild-setup-cluster
```
This interactive script will:
- Configure network settings (router IP, DNS, DHCP range)
- Configure cluster settings (Talos version, schematic ID, MetalLB pool)
- Help you register control plane and worker nodes by detecting their hardware
- Generate machine configurations for each node
- Apply machine configurations to nodes
- Bootstrap the cluster after the first node.
### Install Cluster Services
```bash
wild-setup-services
```
## Installing Wild Cloud Apps
```bash
# List available applications
wild-apps-list
# Deploy an application
wild-app-deploy <app-name>
# Check app status
wild-app-doctor <app-name>
# Remove an application
wild-app-delete <app-name>
```
## Individual Node Management
If you need to manage individual nodes:
```bash
# Generate patch for a specific node
wild-cluster-node-patch-generate <node-ip>
# Generate final machine config (uses existing patch)
wild-cluster-node-machine-config-generate <node-ip>
# Apply configuration with options
wild-cluster-node-up <node-ip> [--insecure] [--skip-patch] [--dry-run]
```
## Asset Management
```bash
# Download/cache boot assets (kernel, initramfs, ISO, iPXE)
wild-cluster-node-boot-assets-download
# Install dnsmasq with specific schematic
wild-dnsmasq-install --schematic-id <id> --install

Your wild-cloud apps are stored in the `apps/` directory. You can change them however you like. You should keep them all in git and make commits anytime you change something. Some `wild` commands will overwrite files in your app directory (like when you are updating apps, or updating your configuration) so you'll want to review any changes made to your files after using them using `git`.

# Making Backups
This guide covers how to create backups of your wild-cloud infrastructure using the integrated backup system.
## Overview
The wild-cloud backup system creates encrypted, deduplicated snapshots using restic. It backs up three main components:
- **Applications**: Database dumps and persistent volume data
- **Cluster**: Kubernetes resources and etcd state
- **Configuration**: Wild-cloud repository and settings
## Prerequisites
Before making backups, ensure you have:
1. **Environment configured**: Run `source env.sh` to load backup configuration
2. **Restic repository**: Backup repository configured in `config.yaml`
3. **Backup password**: Set in wild-cloud secrets
4. **Staging directory**: Configured path for temporary backup files
## Backup Components
### Applications (`wild-app-backup`)
Backs up individual applications including:
- **Database dumps**: PostgreSQL/MySQL databases in compressed custom format
- **PVC data**: Application files streamed directly for restic deduplication
- **Auto-discovery**: Finds databases and PVCs based on app manifest.yaml
### Cluster Resources (`wild-backup --cluster-only`)
Backs up cluster-wide resources:
- **Kubernetes resources**: All pods, services, deployments, secrets, configmaps
- **Storage definitions**: PersistentVolumes, PVCs, StorageClasses
- **etcd snapshot**: Complete cluster state for disaster recovery
### Configuration (`wild-backup --home-only`)
Backs up wild-cloud configuration:
- **Repository contents**: All app definitions, manifests, configurations
- **Settings**: Wild-cloud configuration files and customizations
## Making Backups
### Full System Backup (Recommended)
Create a complete backup of everything:
```bash
# Backup all components (apps + cluster + config)
wild-backup
```
This is equivalent to:
```bash
wild-backup --home --apps --cluster
```
### Selective Backups
#### Applications Only
```bash
# All applications
wild-backup --apps-only
# Single application
wild-app-backup discourse
# Multiple applications
wild-app-backup discourse gitea immich
```
#### Cluster Only
```bash
# Kubernetes resources + etcd
wild-backup --cluster-only
```
#### Configuration Only
```bash
# Wild-cloud repository
wild-backup --home-only
```
### Excluding Components
Skip specific components:
```bash
# Skip config, backup apps + cluster
wild-backup --no-home
# Skip applications, backup config + cluster
wild-backup --no-apps
# Skip cluster resources, backup config + apps
wild-backup --no-cluster
```
## Backup Process Details
### Application Backup Process
1. **Discovery**: Parses `manifest.yaml` to find database and PVC dependencies
2. **Database backup**: Creates compressed custom-format dumps
3. **PVC backup**: Streams files directly to staging for restic deduplication
4. **Staging**: Organizes files in clean directory structure
5. **Upload**: Creates individual restic snapshots per application
### Cluster Backup Process
1. **Resource export**: Exports all Kubernetes resources to YAML
2. **etcd snapshot**: Creates point-in-time etcd backup via talosctl
3. **Upload**: Creates single restic snapshot for cluster state
### Restic Snapshots
Each backup creates tagged restic snapshots:
```bash
# View all snapshots
restic snapshots
# Filter by component
restic snapshots --tag discourse # Specific app
restic snapshots --tag cluster # Cluster resources
restic snapshots --tag wc-home # Wild-cloud config
```
## Where Backup Files Are Staged
Before uploading to your restic repository, backup files are organized in a staging directory. This temporary area lets you see exactly what's being backed up and helps with deduplication.
Here's what the staging area looks like:
```
backup-staging/
├── apps/
│ ├── discourse/
│ │ ├── database_20250816T120000Z.dump
│ │ ├── globals_20250816T120000Z.sql
│ │ └── discourse/
│ │ └── data/ # All the actual files
│ ├── gitea/
│ │ ├── database_20250816T120000Z.dump
│ │ └── gitea-data/
│ │ └── data/ # Git repositories, etc.
│ └── immich/
│ ├── database_20250816T120000Z.dump
│ └── immich-data/
│ └── upload/ # Photos and videos
└── cluster/
├── all-resources.yaml # All running services
├── secrets.yaml # Passwords and certificates
├── configmaps.yaml # Configuration data
└── etcd-snapshot.db # Complete cluster state
```
This staging approach means you can examine backup contents before they're uploaded, and restic can efficiently deduplicate files that haven't changed.
## Advanced Usage
### Custom Backup Scripts
Applications can provide custom backup logic:
```bash
# Create apps/myapp/backup.sh for custom behavior
chmod +x apps/myapp/backup.sh
# wild-app-backup will use custom script if present
wild-app-backup myapp
```
### Monitoring Backup Status
```bash
# Check recent snapshots
restic snapshots | head -20
# Check specific app backups
restic snapshots --tag discourse
# Verify backup integrity
restic check
```
### Backup Automation
Set up automated backups with cron:
```bash
# Daily full backup at 2 AM
0 2 * * * cd /data/repos/payne-cloud && source env.sh && wild-backup
# Hourly app backups during business hours
0 9-17 * * * cd /data/repos/payne-cloud && source env.sh && wild-backup --apps-only
```
## Performance Considerations
### Large PVCs (like Immich photos)
The streaming backup approach provides:
- **First backup**: Full transfer time (all files processed)
- **Subsequent backups**: Only changed files processed (dramatically faster)
- **Storage efficiency**: Restic deduplication reduces storage usage
### Network Usage
- **Database dumps**: Compressed at source, efficient transfer
- **PVC data**: Uncompressed transfer, but restic handles deduplication
- **etcd snapshots**: Small files, minimal impact
## Troubleshooting
### Common Issues
**"No databases or PVCs found"**
- App has no `manifest.yaml` with database dependencies
- No PVCs with matching labels in app namespace
- Create custom `backup.sh` script for special cases
**"kubectl not found"**
- Ensure kubectl is installed and configured
- Check cluster connectivity with `kubectl get nodes`
**"Staging directory not set"**
- Configure `cloud.backup.staging` in `config.yaml`
- Ensure directory exists and is writable
**"Could not create etcd backup"**
- Ensure `talosctl` is installed for Talos clusters
- Check control plane node connectivity
- Verify etcd pods are accessible in kube-system namespace
### Backup Verification
Always verify backups periodically:
```bash
# Check restic repository integrity
restic check
# List recent snapshots
restic snapshots --compact
# Test restore to different directory
restic restore latest --target /tmp/restore-test
```
## Security Notes
- **Encryption**: All backups are encrypted with your backup password
- **Secrets**: Kubernetes secrets are included in cluster backups
- **Access control**: Secure your backup repository and passwords
- **Network**: Consider bandwidth usage for large initial backups
## Next Steps
- [Restoring Backups](restoring-backups.md) - Learn how to restore from backups
- Configure automated backup schedules
- Set up backup monitoring and alerting
- Test disaster recovery procedures

# Node Setup Guide
This guide covers setting up Talos Linux nodes for your Kubernetes cluster using USB boot.
## Overview
There are two main approaches for booting Talos nodes:
1. **USB Boot** (covered here) - Boot from a custom USB drive with system extensions
2. **PXE Boot** - Network boot using dnsmasq setup (see `setup/dnsmasq/README.md`)
## USB Boot Setup
### Prerequisites
- Target hardware for Kubernetes nodes
- USB drive (8GB+ recommended)
- Admin access to create bootable USB drives
### Step 1: Upload Schematic and Download Custom Talos ISO
First, upload the system extensions schematic to Talos Image Factory, then download the custom ISO.
```bash
# Upload schematic configuration to get schematic ID
wild-talos-schema
# Download custom ISO with system extensions
wild-talos-iso
```
The custom ISO includes system extensions (iscsi-tools, util-linux-tools, intel-ucode, gvisor) needed for the cluster and is saved to `.wildcloud/iso/talos-v1.10.3-metal-amd64.iso`.
### Step 2: Create Bootable USB Drive
#### Linux (Recommended)
```bash
# Find your USB device (be careful to select the right device!)
lsblk
sudo dmesg | tail # Check for recently connected USB devices
# Create bootable USB (replace /dev/sdX with your USB device)
sudo dd if=.wildcloud/iso/talos-v1.10.3-metal-amd64.iso of=/dev/sdX bs=4M status=progress sync
# Verify the write completed
sync
```
**⚠️ Warning**: Double-check the device path (`/dev/sdX`). Writing to the wrong device will destroy data!
#### macOS
```bash
# Find your USB device
diskutil list
# Unmount the USB drive (replace diskX with your USB device)
diskutil unmountDisk /dev/diskX
# Create bootable USB
sudo dd if=.wildcloud/iso/talos-v1.10.3-metal-amd64.iso of=/dev/rdiskX bs=4m
# Eject when complete
diskutil eject /dev/diskX
```
#### Windows
Use one of these tools:
1. **Rufus** (Recommended)
- Download from https://rufus.ie/
- Select the Talos ISO file
- Choose your USB drive
- Use "DD Image" mode
- Click "START"
2. **Balena Etcher**
- Download from https://www.balena.io/etcher/
- Flash from file → Select Talos ISO
- Select target USB drive
- Flash!
3. **Command Line** (Windows 10/11)
```cmd
# List disks to find USB drive number

list disk
exit
# Write ISO (replace X with your USB disk number)
dd if=.wildcloud\iso\talos-v1.10.3-metal-amd64.iso of=\\.\PhysicalDriveX bs=4M --progress
```
### Step 3: Boot Target Machine
1. **Insert USB** into target machine
2. **Boot from USB**:
- Restart machine and enter BIOS/UEFI (usually F2, F12, DEL, or ESC during startup)
- Change boot order to prioritize USB drive
- Or use one-time boot menu (usually F12)
3. **Talos will boot** in maintenance mode with a DHCP IP
### Step 4: Hardware Detection and Configuration
Once the machine boots, it will be in maintenance mode with a DHCP IP address.
```bash
# Find the node's maintenance IP (check your router/DHCP server)
# Then detect hardware and register the node
cd setup/cluster-nodes
./detect-node-hardware.sh <maintenance-ip> <node-number>
# Example: Node got DHCP IP 192.168.8.150, registering as node 1
./detect-node-hardware.sh 192.168.8.150 1
```
This script will:
- Discover network interface names (e.g., `enp4s0`)
- List available disks for installation
- Update `config.yaml` with node-specific hardware settings
### Step 5: Generate and Apply Configuration
```bash
# Generate machine configurations with detected hardware
./generate-machine-configs.sh
# Apply configuration (node will reboot with static IP)
talosctl apply-config --insecure -n <maintenance-ip> --file final/controlplane-node-<number>.yaml
# Example:
talosctl apply-config --insecure -n 192.168.8.150 --file final/controlplane-node-1.yaml
```
### Step 6: Verify Installation
After reboot, the node should come up with its assigned static IP:
```bash
# Check connectivity (node 1 should be at 192.168.8.31)
ping 192.168.8.31
# Verify system extensions are installed
talosctl -e 192.168.8.31 -n 192.168.8.31 get extensions
# Check for iscsi tools
talosctl -e 192.168.8.31 -n 192.168.8.31 list /usr/local/bin/ | grep iscsi
```
## Repeat for Additional Nodes
For each additional control plane node:
1. Boot with the same USB drive
2. Run hardware detection with the new maintenance IP and node number
3. Generate and apply configurations
4. Verify the node comes up at its static IP
Example for node 2:
```bash
./detect-node-hardware.sh 192.168.8.151 2
./generate-machine-configs.sh
talosctl apply-config --insecure -n 192.168.8.151 --file final/controlplane-node-2.yaml
```
## Cluster Bootstrap
Once all control plane nodes are configured:
```bash
# Bootstrap the cluster using the VIP
talosctl bootstrap -n 192.168.8.30
# Get kubeconfig
talosctl kubeconfig
# Verify cluster
kubectl get nodes
```
## Troubleshooting
### USB Boot Issues
- **Machine won't boot from USB**: Check BIOS boot order, disable Secure Boot if needed
- **Talos doesn't start**: Verify ISO was written correctly, try re-creating USB
- **Network issues**: Ensure DHCP is available on your network
### Hardware Detection Issues
- **Node not accessible**: Check IP assignment, firewall settings
- **Wrong interface detected**: Manual override in `config.yaml` if needed
- **Disk not found**: Verify disk size (must be >10GB), check disk health
### Installation Issues
- **Static IP not assigned**: Check network configuration in machine config
- **Extensions not installed**: Verify ISO includes extensions, check upgrade logs
- **Node won't join cluster**: Check certificates, network connectivity to VIP
### Checking Logs
```bash
# View system logs
talosctl -e <node-ip> -n <node-ip> logs machined
# Check kernel messages
talosctl -e <node-ip> -n <node-ip> dmesg
# Monitor services
talosctl -e <node-ip> -n <node-ip> get services
```
## System Extensions Included
The custom ISO includes these extensions:
- **siderolabs/iscsi-tools**: iSCSI initiator tools for persistent storage
- **siderolabs/util-linux-tools**: Utility tools including fstrim for storage
- **siderolabs/intel-ucode**: Intel CPU microcode updates (harmless on AMD)
- **siderolabs/gvisor**: Container runtime sandbox (optional security enhancement)
These extensions enable:
- Longhorn distributed storage
- Improved security isolation
- CPU microcode updates
- Storage optimization tools
## Next Steps
After all nodes are configured:
1. **Install CNI**: Deploy a Container Network Interface (Cilium, Calico, etc.)
2. **Install CSI**: Deploy Container Storage Interface (Longhorn for persistent storage)
3. **Deploy workloads**: Your applications and services
4. **Monitor cluster**: Set up monitoring and logging

# Restoring Backups
This guide will walk you through restoring your applications and cluster from wild-cloud backups. Hopefully you'll never need this, but when you do, it's critical that the process works smoothly.
## Understanding Restore Types
Your wild-cloud backup system can restore different types of data depending on what you need to recover:
**Application restores** bring back individual applications by restoring their database contents and file storage. This is what you'll use most often - maybe you accidentally deleted something in Discourse, or Gitea got corrupted, or you want to roll back Immich to before a bad update.
**Cluster restores** are for disaster recovery scenarios where you need to rebuild your entire Kubernetes cluster from scratch. This includes restoring all the cluster's configuration and even its internal state.
**Configuration restores** bring back your wild-cloud repository and settings, which contain all the "recipes" for how your infrastructure should be set up.
## Before You Start Restoring
Make sure you have everything needed to perform restores. You need to be in your wild-cloud directory with the environment loaded (`source env.sh`). Your backup repository and password should be configured and working - you can test this by running `restic snapshots` to see your available backups.
Most importantly, make sure you have kubectl access to your cluster, since restores involve creating temporary pods and manipulating storage.
## Restoring Applications
### Basic Application Restore
The most common restore scenario is bringing back a single application. To restore the latest backup of an app:
```bash
wild-app-restore discourse
```
This restores both the database and all file storage for the discourse app. The restore system automatically figures out what the app needs based on its manifest file and what was backed up.
If you want to restore from a specific backup instead of the latest:
```bash
wild-app-restore discourse abc123
```
Where `abc123` is the snapshot ID from `restic snapshots --tag discourse`.
### Partial Restores
Sometimes you only need to restore part of an application. Maybe the database is fine but the files got corrupted, or vice versa.
To restore only the database:
```bash
wild-app-restore discourse --db-only
```
To restore only the file storage:
```bash
wild-app-restore discourse --pvc-only
```
To restore without database roles and permissions (if they're causing conflicts):
```bash
wild-app-restore discourse --skip-globals
```
### Finding Available Backups
To see what backups are available for an app:
```bash
wild-app-restore discourse --list
```
This shows recent snapshots with their IDs, timestamps, and what was included.
## How Application Restores Work
Understanding what happens during a restore can help when things don't go as expected.
### Database Restoration
When restoring a database, the system first downloads the backup files from your restic repository. It then prepares the database by creating any needed roles, disconnecting existing users, and dropping/recreating the database to ensure a clean restore.
For PostgreSQL databases, it uses `pg_restore` with parallel processing to speed up large database imports. For MySQL, it uses standard mysql import commands. The system also handles database ownership and permissions automatically.
### File Storage Restoration
File storage (PVC) restoration is more complex because it involves safely replacing files that might be actively used by running applications.
First, the system creates a safety snapshot using Longhorn. This means if something goes wrong during the restore, you can get back to where you started. Then it scales your application down to zero replicas so no pods are using the storage.
Next, it creates a temporary utility pod with the PVC mounted and copies all the backup files into place, preserving file permissions and structure. Once the data is restored and verified, it removes the utility pod and scales your application back up.
If everything worked correctly, the safety snapshot is automatically deleted. If something went wrong, the safety snapshot is preserved so you can recover manually.
## Cluster Disaster Recovery
Cluster restoration is much less common but critical when you need to rebuild your entire infrastructure.
### Restoring Kubernetes Resources
To restore all cluster resources from a backup:
```bash
# Download cluster backup
restic restore --tag cluster latest --target ./restore/
# Apply all resources
kubectl apply -f restore/cluster/all-resources.yaml
```
You can also restore specific types of resources:
```bash
kubectl apply -f restore/cluster/secrets.yaml
kubectl apply -f restore/cluster/configmaps.yaml
```
### Restoring etcd State
**Warning: This is extremely dangerous and will affect your entire cluster.**
etcd restoration should only be done when rebuilding a cluster from scratch. For Talos clusters:
```bash
talosctl --nodes <control-plane-ip> etcd restore --from ./restore/cluster/etcd-snapshot.db
```
This command stops etcd, replaces its data with the backup, and restarts the cluster. Expect significant downtime while the cluster rebuilds itself.
## Common Disaster Recovery Scenarios
### Complete Application Loss
When an entire application is gone (namespace deleted, pods corrupted, etc.):
```bash
# Make sure the namespace exists
kubectl create namespace discourse --dry-run=client -o yaml | kubectl apply -f -
# Apply the application manifests if needed
kubectl apply -f apps/discourse/
# Restore the application data
wild-app-restore discourse
```
### Complete Cluster Rebuild
When rebuilding a cluster from scratch:
First, build your new cluster infrastructure and install wild-cloud components. Then configure backup access so you can reach your backup repository.
Restore cluster state:
```bash
restic restore --tag cluster latest --target ./restore/
# Apply etcd snapshot using appropriate method for your cluster type
```
Finally, restore all applications:
```bash
# See what applications are backed up
wild-app-restore --list
# Restore each application individually
wild-app-restore discourse
wild-app-restore gitea
wild-app-restore immich
```
### Rolling Back After Bad Changes
Sometimes you need to undo recent changes to an application:
```bash
# See available snapshots
wild-app-restore discourse --list
# Restore from before the problematic changes
wild-app-restore discourse abc123
```
## Cross-Cluster Migration
You can use backups to move applications between clusters:
On the source cluster, create a fresh backup:
```bash
wild-app-backup discourse
```
On the target cluster, deploy the application manifests:
```bash
kubectl apply -f apps/discourse/
```
Then restore the data:
```bash
wild-app-restore discourse
```
## Verifying Successful Restores
After any restore, verify that everything is working correctly.
For databases, check that you can connect and see expected data:
```bash
kubectl exec -n postgres deploy/postgres-deployment -- \
psql -U postgres -d discourse -c "SELECT count(*) FROM posts;"
```
For file storage, check that files exist and applications can start:
```bash
kubectl get pods -n discourse
kubectl logs -n discourse deployment/discourse
```
For web applications, test that you can access them:
```bash
curl -f https://discourse.example.com/latest.json
```
## When Things Go Wrong
### No Snapshots Found
If the restore system can't find backups for an application, check that snapshots exist:
```bash
restic snapshots --tag discourse
```
Make sure you're using the correct app name and that backups were actually created successfully.
### Database Restore Failures
Database restores can fail if the target database isn't accessible or if there are permission issues. Check that your postgres or mysql pods are running and that you can connect to them manually.
Review the restore error messages carefully - they usually indicate whether the problem is with the backup file, database connectivity, or permissions.
### PVC Restore Failures
If PVC restoration fails, check that you have sufficient disk space and that the PVC isn't being used by other pods. The error messages will usually indicate what went wrong.
Most importantly, remember that safety snapshots are preserved when PVC restores fail. You can see them with:
```bash
kubectl get snapshot.longhorn.io -n longhorn-system -l app=wild-app-restore
```
These snapshots let you recover to the pre-restore state if needed.
### Application Won't Start After Restore
If pods fail to start after restoration, check file permissions and ownership. Sometimes the restoration process doesn't perfectly preserve the exact permissions that the application expects.
You can also try scaling the application to zero and back to one, which sometimes resolves transient issues:
```bash
kubectl scale deployment/discourse -n discourse --replicas=0
kubectl scale deployment/discourse -n discourse --replicas=1
```
## Manual Recovery
When automated restore fails, you can always fall back to manual extraction and restoration:
```bash
# Extract backup files to local directory
restic restore --tag discourse latest --target ./manual-restore/
# Manually copy database dump to postgres pod
kubectl cp ./manual-restore/discourse/database_*.dump \
postgres/postgres-deployment-xxx:/tmp/
# Manually restore database
kubectl exec -n postgres deploy/postgres-deployment -- \
pg_restore -U postgres -d discourse /tmp/database_*.dump
```
For file restoration, you'd need to create a utility pod and manually copy files into the PVC.
## Best Practices
Test your restore procedures regularly in a non-production environment. It's much better to discover issues with your backup system during a planned test than during an actual emergency.
Always communicate with users before performing restores, especially if they involve downtime. Document any manual steps you had to take so you can improve the automated process.
After any significant restore, monitor your applications more closely than usual for a few days. Sometimes problems don't surface immediately.
## Security and Access Control
Restore operations are powerful and can be destructive. Make sure only trusted administrators can perform restores, and consider requiring approval or coordination before major restoration operations.
Be aware that cluster restores include all secrets, so they potentially expose passwords, API keys, and certificates. Ensure your backup repository is properly secured.
Remember that Longhorn safety snapshots are preserved when things go wrong. These snapshots may contain sensitive data, so clean them up appropriately once you've resolved any issues.
## What's Next
The best way to get comfortable with restore operations is to practice them in a safe environment. Set up a test cluster and practice restoring applications and data.
Consider creating runbooks for your most likely disaster scenarios, including the specific commands and verification steps for your infrastructure.
Read the [Making Backups](making-backups.md) guide to ensure you're creating the backups you'll need for successful recovery.

# Security
## Best Practices
1. **Keep Everything Updated**:
- Regularly update K3s
- Update all infrastructure components
- Keep application images up to date
2. **Network Security**:
- Use internal services whenever possible
- Limit exposed services to only what's necessary
- Configure your home router's firewall properly
3. **Access Control**:
- Use strong passwords for all services
- Implement a secrets management strategy
- Rotate API tokens and keys regularly
4. **Regular Audits**:
- Review running services periodically
- Check for unused or outdated deployments
- Monitor resource usage for anomalies
## Security Scanning (Future Implementation)
Tools to consider implementing:
1. **Trivy** for image scanning:
```bash
# Example Trivy usage (placeholder)
trivy image <your-image>
```
2. **kube-bench** for Kubernetes security checks:
```bash
# Example kube-bench usage (placeholder)
kubectl apply -f https://raw.githubusercontent.com/aquasecurity/kube-bench/main/job.yaml
```
3. **Falco** for runtime security monitoring:
```bash
# Example Falco installation (placeholder)
helm repo add falcosecurity https://falcosecurity.github.io/charts
helm install falco falcosecurity/falco --namespace falco --create-namespace
