Claude Code Bible

Official documentation reference management for Claude Code.

Purpose

Maintain up-to-date local copies of Claude Code official documentation.

Commands

/claude-code-bible update

Fetch the latest documentation from code.claude.com.

What it does:

• Fetches https://code.claude.com/docs/llms.txt
• Extracts all documentation URLs from the llms.txt content
• Downloads each documentation page and saves as markdown
• Writes a timestamp file for cache tracking
• Respects a 24-hour cache (skip if fresh, unless --force used)

Usage:

# Fetch latest docs (skip if cached < 24h)
node .codex/skills/claude-code-bible/scripts/fetch-docs.js

# Force update even if cache is fresh
node .codex/skills/claude-code-bible/scripts/fetch-docs.js --force

# Custom output directory
node .codex/skills/claude-code-bible/scripts/fetch-docs.js --output /path/to/output

Default output location:

~/.codex/references/claude-code/
├── llms.txt              # Master index
├── last-updated.txt      # ISO timestamp
├── <doc-name>.md         # Individual doc pages
└── ...

Exit codes:

• 0: Success (or cache is fresh)
• 1: Fatal error

Implementation Notes

Fetch Script (fetch-docs.js)

Features:

• Uses only Node.js built-in modules (https, fs, path)
• Handles HTTP redirects (3xx responses)
• Respects server with 200ms delay between requests
• 24-hour cache to avoid unnecessary fetches
• Comprehensive error reporting

Cache behavior:

• Checks last-updated.txt timestamp
• Skips fetch if < 24 hours old (unless --force)
• Always updates timestamp on successful fetch

Error handling:

• Reports HTTP errors with status codes
• Continues on individual page failures
• Prints summary of successes and failures

Integration with Other Skills

• Should update local docs first: /claude-code-bible update

dev-review

• Can reference official docs for best practices

Benefits

1. Up-to-date: Always have latest documentation locally
2. Offline access: Work with docs even without internet
3. Learning: Reference official patterns when creating new components

Notes

• The fetch script is production-ready and can be used immediately
• Consider running /claude-code-bible update weekly to stay current
