name: tidb-doc-finder description: "TiDB-specific documentation lookup guided by this repo's llms.txt hub: read llms.txt, pick the best linked source (tidb-dev-guide llms-full.txt, TiDB user guide llms.txt, or Uber Go style guide), fetch it, then search within it to answer with precise references. Use when asked to find docs, research, or provide doc-grounded answers about TiDB development or usage."

tidb-doc-finder

Use llms.txt in the current repo as the single source of truth for "where to look".

Workflow

1. Read the hub

   • Open llms.txt and extract the doc endpoints (URLs).
   • Do not hardcode URLs elsewhere; llms.txt is authoritative.

2. If MCP tidb-doc-ext is available, prefer it

   • Use the MCP to fetch documentation content.
   • Only request markdown sources; do not fetch HTML or URLs without a file extension.
   • If MCP is available, use it instead of the local fetch/cache scripts; otherwise fall back to the scripts below.

3. Select the best source

   • TiDB dev / contribution / architecture -> TiDB Developer Guide (llms-full.txt)
   • TiDB SQL behavior / user-facing features / releases -> TiDB User Guide (llms.txt)
   • Go style / idioms -> Uber Go Style Guide (style.md)

4. Fetch to a local cache file (recommended)

   • Use tidb-doc-finder/scripts/fetch.sh to download and cache the selected source.
   • Keep the cache so subsequent searches are fast and can be done offline.

5. Search within the fetched file

   • Use tidb-doc-finder/scripts/search.sh <cached_file> <query> to:
     • find the most relevant sections,
     • show a small excerpt,
     • and capture headings/anchors if present.

6. Answer with doc-grounded output

   • Provide a direct answer.
   • Include the source URL from llms.txt and the matched heading/section name.
   • If the doc does not contain the answer, say so and propose the next-best source (still chosen from llms.txt).

Commands

• Fetch: bash tidb-doc-finder/scripts/fetch.sh <url>
• Search: bash tidb-doc-finder/scripts/search.sh <cached_file> <query>
