+This file provides guidance to Claude Code (claude.ai/code) when working
+with code in this repository.
+
+## Overview
+
+protonmail is a CLI tool for accessing and managing ProtonMail emails via Bridge.
+All commands work with local cached .eml files for fast, offline access.
+
+## Commands
+
+```bash
+uv sync                            # Install dependencies
+uv run protonmail --version        # Show version
+uv run protonmail sync             # Sync emails from Bridge
+uv run protonmail list             # List cached emails
+uv run protonmail read <file>      # Read a specific email
+uv run protonmail search <query>   # Search by subject/sender
+uv run pytest tests/ -v            # Run tests
+uv run ruff check .                # Lint
+uv run ruff format .               # Format
+```
+
