# Claude Code

## Overview

Claude Code is Anthropic's official CLI providing specialized subagents, extensibility (plugins, skills, hooks, MCP), and enterprise features (sandboxing, monitoring). See [references/claude-code-urls.md](references/claude-code-urls.md) for the full documentation index.

## Instructions

### Step 0 — Refresh the doc index when fetching docs

If you need to consult the official docs to answer (i.e. you'll hit step 1 or step 2 below), run `bash ~/.claude/skills/claude-code/scripts/fetch-claude-code-urls.sh` first to rewrite `references/claude-code-urls.md` from Anthropic's current `llms.txt`. Skip the refresh for purely conceptual answers or when the existing snapshot is sufficient.

### Step 1 — Find the relevant doc

Read [references/claude-code-urls.md](references/claude-code-urls.md) to find the matching doc. Each line is:

```
- [Title](https://code.claude.com/docs/en/<page>.md): <description>
```

Match the user's question to the most relevant entry by title or description.

**If no good match is found:**
- Try broad matching (e.g., user asks about "permissions" → check `settings.md`, `permissions.md`, `plugins.md`)
- If still no match, try WebFetch of the most likely URL from the topic table below
- If that fails, answer directly from your knowledge and suggest the user check the official docs at `https://code.claude.com/docs`

### Step 2 — Answer the question

**For capability/concept questions** ("can Claude Code do X?", "what is Y?"):
- Answer directly from your knowledge if confident
- Cite the matching URL from `claude-code-urls.md` for further reading

**For implementation/configuration questions** (formats, schemas, syntax, step-by-step):
- WebFetch the `.md` URL from `claude-code-urls.md` to get current, accurate details
- Provide complete working examples with file paths
- Always cite the source URL
- If WebFetch fails, answer from your knowledge and note that you're using cached information
