Claude Code Documentation Mirror

Local mirror of Claude Code documentation files from https://docs.anthropic.com/en/docs/claude-code/, updated every 3 hours.

Why This Exists

• Faster than web fetching - Read from local files instantly
• Works offline - No internet required after cloning
• Always up-to-date - Auto-updates every 3 hours via GitHub Actions

Prerequisites

This tool requires the following to be installed:

• git - For cloning and updating the repository
• jq - For JSON processing in the auto-update hook
• curl - For downloading the installation script
• Claude Code - Obviously :)

Platform Support: Currently macOS only. Linux support contributions welcome!

Installation

Run this single command from wherever you want to store the docs:

curl -fsSL https://raw.githubusercontent.com/shaneholloman/claude-code-docs/main/install.sh | bash

This will:

1. Clone the repository (or use existing if found)
2. Create the /user:docs slash command
3. Set up automatic git pull when reading docs

Note: The command is /user:docs (not /docs). If you have a different docs command from another installation, both will coexist.

Usage

The /user:docs command provides instant access to documentation with optional freshness checking.

Default: Lightning-fast access (no checks)

/user:docs hooks        # Instantly read hooks documentation
/user:docs mcp          # Instantly read MCP documentation
/user:docs memory       # Instantly read memory documentation

You'll see: Reading from local docs (run /user:docs -t to check freshness)

Optional: Check documentation freshness with -t flag

/user:docs -t           # Show when docs were last updated
/user:docs -t hooks     # Check freshness, then read hooks docs
/user:docs -t mcp       # Check freshness, then read MCP docs

The -t flag shows:

• When GitHub last updated the docs
• When your local copy last synced
• Triggers a sync if it's been 3+ hours

Creative usage examples

# Natural language queries work great
/user:docs what environment variables exist and how do I use them?
/user:docs explain the differences between hooks and MCP

# Check for recent changes
/user:docs -t what's new in the latest documentation?

# Search across all docs
/user:docs find all mentions of authentication
/user:docs how do I customize Claude Code's behavior?

Performance notes

• Default mode: Zero overhead - reads docs instantly
• With -t flag: Checks timestamps and syncs if needed (only every 3 hours)
• Error handling: If docs are missing, you'll see instructions to reinstall

How Updates Work

The docs automatically stay up-to-date:

• GitHub Actions updates the repository every 3 hours
• The hook compares GitHub's timestamp with your local sync time
• If GitHub has newer content, it automatically syncs before reading
• You'll see "🔄 Updating docs to latest version..." when this happens
• No manual updates needed!

Performance:

• /user:docs reads instantly and the hook ensures content is always current
• /user:docs -t shows you exact timestamps of GitHub updates vs local sync

Troubleshooting

Command not found

If /user:docs returns "command not found":

1. Check if the command file exists: ls ~/.claude/commands/docs.md
2. Restart Claude Code to reload commands
3. Re-run the installation script

Documentation not updating

If documentation seems outdated:

1. Run /user:docs -t to check sync status and force an update
2. Manually update: cd /path/to/claude-code-docs && git pull
3. Check if GitHub Actions are running: View Actions

Installation errors

• "git/jq/curl not found": Install the missing tool first
• "Failed to clone repository": Check your internet connection
• "Failed to update settings.json": Check file permissions on ~/.claude/settings.json

Hook not working

If docs aren't auto-updating:

1. Check your Claude settings: cat ~/.claude/settings.json | jq .hooks
2. Look for error messages when using /user:docs
3. Re-run the installer to reset the hook

Uninstalling

To completely remove the docs integration:

1. Remove the command file:

   rm ~/.claude/commands/docs.md

2. Remove the auto-update hook:

   • Run /hooks in Claude Code
   • Find "PreToolUse - Matcher: Read"
   • Select the hook and remove it

3. Delete the repository:

   rm -rf /path/to/claude-code-docs

Security Notes

• The installer modifies ~/.claude/settings.json to add an auto-update hook
• The hook only runs git pull when reading documentation files
• All operations are limited to the documentation directory
• No data is sent externally - everything is local
• Repository Trust: The installer clones from GitHub over HTTPS. For additional security, you can:
  • Fork the repository and install from your own fork
  • Clone manually and run the installer from the local directory
  • Review all code before installation
