CodeGraph

Use an existing CodeGraph index when the installed integration can answer the structural question.

Discover access

1. Find the task's repository and inspect whether it has a CodeGraph index.
2. Discover available host tools and installed CLI help. An index directory alone does not prove that a server, binary, or watcher works.
3. Follow the host's code-intelligence precedence. Use LSP for definitions, references, and implementations when that is its primary route.
4. Use CodeGraph for supported graph exploration, impact analysis, or affected-test discovery.
5. Use native text/file tools for exact searches and current-source verification.

Do not initialize an index unless the user requests or approves it. Do not activate another indexing backend automatically as a fallback.

Query narrowly

Start with a known symbol, route, file, or question. Read the tool's current schema before calling it. Inspect returned source and graph limitations; dynamic dispatch and runtime registration may be incomplete.

If only CLI access is available, discover its supported verbs and flags with local help. Do not assume commands from another CodeGraph distribution apply.
