Claude Code Documentation Tool

Enhanced fork of ericbuess/claude-code-docs with native plugin support, auto-discovery Skill, and AI-powered semantic search.

Official Claude docs, always up-to-date, always at your fingertips. Stop searching the web — ask Claude directly and get accurate answers grounded in official documentation.

Why Use This?

Claude knows a lot — but documentation changes fast. API parameters shift, new features land, SDK methods get renamed. This tool gives Claude a local mirror of every official doc page, so answers come from the source, not stale training data.

Without claude-code-docs	With claude-code-docs
Claude guesses from training data	Claude reads the latest official docs
Broken or outdated URLs in answers	Correct platform.claude.com / code.claude.com links
"I think the API works like..."	"According to the documentation..."
You verify answers manually	Answers cite specific doc pages

Quick Start — Plugin Install (Recommended)

Two commands, no dependencies:

/plugin marketplace add costiash/claude-code-docs
/plugin install claude-docs@claude-code-docs

That's it. On your next session Claude will automatically:

1. Clone all documentation files to ~/.claude-code-docs/
2. Keep them updated every session via git pull
3. Make the /docs command available for manual lookups
4. Activate the auto-discovery Skill — Claude reads docs automatically when you ask Claude-related questions

What the Plugin Gets You

• /docs command — Look up any topic: /docs hooks, /docs extended thinking, /docs Agent SDK sessions
• Auto-discovery Skill — Claude proactively searches docs when you ask about Claude Code, the API, SDKs, or prompt engineering. No /docs prefix needed.
• Interactive Courses — Turn any Claude topic into a stunning, self-contained HTML course with animated diagrams, protocol conversations, quizzes, and code translations. Just say "create a course on hooks" or run /docs --course <topic>.
• Session-start auto-updates — Docs stay fresh automatically. No cron jobs, no manual pulls.
• Content search — Shell-based full-text search and fuzzy filename matching, no Python needed
• Zero dependencies — No Python, no jq, no curl. Just Claude Code with plugin support.

Legacy: Script Install (Migration)

For environments without plugin support, the install script clones documentation locally:

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

If Claude Code is detected, the script will guide you to install the plugin instead. Without Claude Code, it falls back to git clone for basic documentation access.

Team / Organization Adoption

Auto-prompt every team member to install the plugin by adding this to your project's .claude/settings.json:

{
  "extraKnownMarketplaces": {
    "claude-code-docs": {
      "source": {
        "source": "github",
        "repo": "costiash/claude-code-docs"
      }
    }
  },
  "enabledPlugins": {
    "claude-docs@claude-code-docs": true
  }
}

Commit this file to your repository. When a team member trusts the project folder, they'll be prompted to install the marketplace and plugin automatically — no manual setup needed.

Interactive Courses — Learn Claude by Doing

This isn't just a docs mirror anymore. Ask about any Claude topic and get a beautifully crafted, interactive HTML course — complete with animated protocol diagrams, hands-on quizzes, code-with-English translations, and a stunning dark Obsidian & Amber visual theme. One self-contained file, zero setup, opens right in your browser.

/docs --course hooks          # Generate a course on Claude Code hooks
/docs --course tool use       # Deep dive into the Tool Use API
/docs --course prompt caching # Master caching with visual explanations

Or just ask naturally after any docs response — Claude will offer to create a course on whatever you just looked up.
