# Claude Code Ultimate Guide - Project Context

## Purpose

This repository is the **comprehensive documentation for Claude Code** (Anthropic's CLI tool). It teaches users how to use Claude Code effectively through guides, examples, and templates.

**Meta-note**: This repo documents Claude Code, so its own configuration should be exemplary.

## Key Files

| File | Purpose |
|------|---------|
| `VERSION` | Single source of truth for version (currently 3.6.1) |
| `guide/ultimate-guide.md` | The main reference (search here first) |
| `guide/cheatsheet.md` | Quick reference for daily use |
| `machine-readable/reference.yaml` | LLM-optimized index with line numbers |
| `CHANGELOG.md` | All changes with detailed descriptions |

## Commands

### Version Management
```bash
# Check version consistency across all docs
./scripts/sync-version.sh --check

# Fix version mismatches (updates from VERSION file)
./scripts/sync-version.sh

# Bump version
echo "3.7.0" > VERSION && ./scripts/sync-version.sh
```

### Before Committing
```bash
# Verify versions are synchronized
./scripts/sync-version.sh --check
```

## Conventions

### Documentation Style
- **Accuracy over marketing**: No invented percentages or unverified claims
- **Practical examples**: Every concept has a concrete example
- **Source attribution**: Credit community contributions with links
- **Version alignment**: All version numbers must match `VERSION` file

### File Organization
- New guides → `guide/`
- New templates → `examples/{agents,commands,hooks,skills}/`
- Navigation updates → Update both `README.md` and `guide/README.md`

### Versioning
- `VERSION` file is the single source of truth
- Run `./scripts/sync-version.sh` after changing version
- Files that contain version: README.md, cheatsheet.md, ultimate-guide.md, reference.yaml

## Current Focus

Check `IDEAS.md` for planned improvements and `CHANGELOG.md [Unreleased]` for work in progress.
