Gives Claude a set of code intelligence commands that run tree-sitter queries instead of reading full files. You get symbol lookups, call graph traces, impact analysis, dead code detection, and refactoring plans across JavaScript, TypeScript, Python, Go, Rust, Java, and HTML. Works without language servers or background processes. Ask Claude to trace execution flow from a function, find all callers of a method, verify call sites match signatures, or identify which tests cover changed code. Everything runs through a single MCP tool that wraps the underlying CLI commands. Useful when you want an agent to navigate a codebase structurally rather than grep through source text or load entire files into context.
