Tools & Capabilities Breakdown

Code Index Tools (14)

code_search

Hybrid (vector + FTS) search for **conceptual** queries (e.g., "auth flow", "where do we parse JSON").

symbol_lookup

Exact-name lookup of functions / classes / methods / types. Prefer over `code_search` for identifiers.

file_outline

Symbols (with signatures) in a file, in source order. Use instead of `Read` when you only need shape.

module_outline

Symbols across a directory subtree in one call. Use instead of looping `file_outline`.

where_am_i

Given `path` + `line`, returns the innermost symbol and the full enclosing chain.

get_symbol_body
