Retrieve the overview / available topics for a repository from Google CodeWiki.

Use this to discover what CodeWiki knows about a repo before asking specific questions with codewiki_search_wiki.

Returns section titles with short content previews (not the full page). For detailed content, call codewiki_read_contents with a section title.

Response size: typically 5–30 KB depending on the repository. Cached for 30 minutes — repeated calls for the same repo are instant.

Rate limit: max 10 calls per 60 s per repo URL. Duplicate concurrent calls are automatically deduplicated.

Args: repo_url: Full repository URL (e.g. https://github.com/microsoft/vscode-copilot-chat) or shorthand owner/repo (e.g. microsoft/vscode-copilot-chat). Bare keywords (e.g. 'vue') are auto-resolved with interactive disambiguation.

Get a list of documentation topics for a repository from Google CodeWiki.

Returns the table of contents / section structure as a JSON list so you can choose which sections to read with codewiki_read_contents.

Recommended first step — call this before codewiki_read_contents or codewiki_list_topics to discover available sections without consuming many tokens.

Response size: typically 1–3 KB (lightweight JSON). Cached for 5 minutes — repeated calls are instant.

Rate limit: max 10 calls per 60 s per repo URL. Duplicate concurrent calls are automatically deduplicated.

Args: repo_url: Full repository URL (e.g. https://github.com/facebook/react) or shorthand owner/repo (e.g. facebook/react). Bare keywords (e.g. 'react') are auto-resolved with interactive disambiguation.

View documentation about a GitHub repository from Google CodeWiki.

Without section_title, returns the full wiki content (may be truncated). With section_title, returns just that section's content.

Use codewiki_read_structure first to see available sections.

Pagination (when section_title is empty):

• offset — section index to start from (default 0).

• limit — max sections per response (default 5). The response includes has_more and next_offset when more sections are available, so you can call again to continue.

Response size: 2–10 KB per section, 5–30 KB for paginated full page. Cached for 5 minutes — repeated calls are instant.

Rate limit: max 10 calls per 60 s per repo URL. Duplicate concurrent calls are automatically deduplicated.

Args: repo_url: Full repository URL (e.g. https://github.com/facebook/react) or shorthand owner/repo (e.g. facebook/react). Bare keywords (e.g. 'react') are auto-resolved with interactive disambiguation. section_title: Optional. Title (or partial title) of a specific section to retrieve. If empty, returns the full wiki. offset: Section index to start from (0-based, default 0). limit: Maximum sections to return (default 5, max 50).

Ask Google CodeWiki a question about an open-source repository.

This uses the interactive chat feature powered by Gemini. For reading wiki content directly, use codewiki_read_contents instead.

Results are cached for 2 minutes — repeated identical queries are instant.

Response size: typically 0.5–5 KB depending on the answer.

Rate limit: max 10 calls per 60 s per repo URL.

Args: repo_url: Full repository URL (e.g. https://github.com/microsoft/vscode-copilot-chat) or shorthand owner/repo (e.g. microsoft/vscode-copilot-chat). Bare keywords (e.g. 'vue') are auto-resolved with interactive disambiguation. query: The question to ask (required).

Request Google CodeWiki to index a repository that is not yet available.

Use this tool when codewiki_list_topics or codewiki_read_structure returns a NOT_INDEXED error, indicating the repository has no CodeWiki documentation yet.

This tool will:

1. Search for the repository on CodeWiki.

2. Click "Request repository" to open the submission dialog.

3. Fill in the GitHub URL and submit the request.

4. Return confirmation and next-step guidance.

Note: Google CodeWiki reviews requests and indexes repositories based on popularity and demand. There is no guaranteed timeline.

Args: repo_url: Full repository URL (e.g. https://github.com/owner/repo) or shorthand owner/repo (e.g. owner/repo). Bare keywords (e.g. 'vue') are auto-resolved with interactive disambiguation.
