Castle Tools

CLI utilities managed by the castle platform. Each tool follows Unix philosophy: read from stdin or file arguments, write to stdout, compose via pipes.

Installation

Each category is its own package, installed individually:

castle sync    # installs all category packages

Or manually install a single category:

uv tool install --editable tools/document/

Directory Structure

tools/
├── <category>/
│   ├── pyproject.toml          # Per-category package
│   └── src/<category>/
│       ├── __init__.py
│       ├── <tool>.py           # Implementation
│       └── <tool>.md           # Documentation (YAML frontmatter + docs)
└── README.md

Each tool has two files:

• <tool>.py -- the implementation, with a main() entry point
• <tool>.md -- YAML frontmatter (command, description, version, category, system_dependencies) followed by usage documentation

Adding a New Tool

castle create my-tool --type tool --category document

Or manually:

1. Create tools/<category>/src/<category>/my_tool.py with an argparse main() function
2. Create tools/<category>/src/<category>/my_tool.md with YAML frontmatter
3. Add the entry point to tools/<category>/pyproject.toml:

   my-tool = "<category>.my_tool:main"
   

4. Register in castle.yaml:

   my-tool:
     description: What it does
     tool:
       tool_type: python_standalone
       category: <category>
       source: tools/<category>/
     install:
       path: { alias: my-tool }
   

5. Run castle sync to install

Tool Types

Castle manages three types of tools:

Type	Description	Installation
python_standalone	Own pyproject.toml	Individual uv tool install per category
script	Bash or binary	Symlinked to ~/.local/bin/

Conventions

• Read from stdin or file argument, write to stdout
• Error messages and status to stderr
• Exit 0 on success, 1 on error
• --help for usage, --version where applicable
• Composable via Unix pipes: pdf2md paper.pdf | gpt "summarize this"
