## MCP tools (17)

### `search_guide` (~102 tokens)

Search the Claude Code Ultimate Guide by topic, keyword, or question. Covers features, hooks, agents, MCP, skills, commands, and best practices. Use this FIRST for any Claude Code question instead of web search.

Input parameters:

- `limit` (number): Max results to return (default 10, max 20)
- `query` (string, required): Search query — topic, question, or keyword (e.g. "hooks", "custom agents", "cost optimization")

### `read_section` (~161 tokens)

Read a section from a guide file (markdown, YAML, examples). Supports pagination via offset, or a "#heading-slug" anchor to jump straight to a section (as returned by search_guide()). Use after search_guide() to fetch the full content at a specific location.

Input parameters:

- `limit` (number): Max lines to return (default 500, max 500)
- `offset` (number): Line number to start reading from (1-based, default 1). Ignored when path has a "#" anchor.
- `path` (string, required): Relative path from repo root, optionally with a "#heading-slug" anchor (e.g. "guide/ultimate-guide.md", "guide/core/memory-systems.md#1-tldr-three-track-model")

### `list_topics` (~32 tokens)

List all top-level topics and categories in the Claude Code Ultimate Guide. Useful for exploring what the guide covers before searching.

### `get_example` (~69 tokens)

Fetch a production-ready template or example from the guide (agents, skills, commands, hooks, scripts). Pass a partial name to search for matching examples.

Input parameters:

- `name` (string, required): Example name or partial match (e.g. "code-reviewer", "pre-commit hook", "custom agent")

### `get_changelog` (~63 tokens)

Return the last N entries from the Claude Code Ultimate Guide CHANGELOG. Shows what changed in the guide itself (not Claude Code CLI releases — use get_release() for that).

Input parameters:

- `count` (number): Number of recent changelog entries to return (default 5)

### `get_digest` (~69 tokens)

Return a digest of guide and Claude Code CLI changes for a given period. Combines guide CHANGELOG entries + official Claude Code releases in the time window.

Input parameters:

- `period` (string, required): Time window: "day" (24h), "week" (7 days), "month" (30 days)

### `get_cheatsheet` (~67 tokens)

Return the Claude Code cheatsheet — a compact 1-page reference covering the most important commands, shortcuts, config options, and workflows.

Input parameters:

- `section` (string): Optional: filter to a specific section (e.g. "installation", "hooks", "agents", "mcp")

### `list_examples` (~68 tokens)

List all production-ready templates in the guide by category (agents, commands, hooks, skills, scripts). Use get_example(name) to fetch the content of any specific template.

Input parameters:

- `category` (string): Filter by category: agents | commands | hooks | skills | scripts. Omit for all.

### `get_release` (~85 tokens)

Get details about Claude Code CLI official releases. Pass a version to get a specific release, or omit to get the latest and recent history.

Input parameters:

- `count` (number): Number of recent releases to show when no version specified (default 5)
- `version` (string): Specific version (e.g. "2.1.59"). Omit for latest + recent 5.

### `compare_versions` (~70 tokens)

Show what changed between two Claude Code CLI versions. Lists all releases in range with aggregated highlights and breaking changes.

Input parameters:

- `from` (string, required): Starting version (older), e.g. "2.1.50"
- `to` (string): Ending version (newer). Omit to use the latest.

### `get_threat` (~90 tokens)

Look up a specific threat by ID from the security threat database. Supports CVE IDs (e.g. "CVE-2025-53109") and technique IDs (e.g. "T001").

Input parameters:

- `id` (string, required): Threat ID: a CVE identifier (e.g. "CVE-2025-53109") or attack technique ID (e.g. "T001")

### `list_threats` (~69 tokens)

Browse the security threat database. Without a category, returns a summary with counts. With a category, returns the full list for that section.

Input parameters:

- `category` (string): Section to list: cves | authors | skills | techniques | mitigations | sources. Omit for a global summary.

### `search_examples` (~97 tokens)

Semantic search across all production-ready templates by intent (e.g. "hook lint", "agent code review"). Different from get_example (exact name) and list_examples (category browse).

Input parameters:

- `limit` (number): Max results to return (default 10, max 20)
- `query` (string, required): Search query describing the template you need, e.g. "hook lint", "agent code review", "pre-commit typescript"

### `init_official_docs` (~66 tokens)

Fetch the official Anthropic Claude Code docs (llms-full.txt) and store a local snapshot as the diff baseline. Run this first. Safe to re-run — overwrites previous baseline AND current. Takes ~5s (fetches ~1.2MB from Anthropic).

### `refresh_official_docs` (~58 tokens)

Re-fetch the official Anthropic Claude Code docs and update the "current" snapshot without touching the baseline. Run this to update the comparison target before diffing. Takes ~5s (fetches ~1.2MB from Anthropic).

### `diff_official_docs` (~64 tokens)

Compare the baseline and current official Anthropic Claude Code docs snapshots. Shows added, removed, and modified pages. No network call — reads local files only. Run init_official_docs() first, then refresh_official_docs() when you want to update the current snapshot.

### `search_official_docs` (~82 tokens)

Search the official Anthropic Claude Code documentation by keyword or topic. Uses the local current snapshot — no network call. Run init_official_docs() first.

Input parameters:

- `limit` (number): Max sections to return (default 5)
- `query` (string, required): Search term or topic (e.g. "hooks", "MCP authentication", "cost limits")
