code-crawler
Answer questions about code relationships in an indexed repository - callers, callees, impact, entry points, routes, DI wiring, dead code, cycles - using the code-crawler MCP server's SQLite property graph. Use when the question is about how symbols connect (who calls this, what breaks if I change it, where does a request enter, is this reachable) rather than about text you can find by searching. Do not crawl a repository just to answer a question about a single file you already have open.
