Codeix

Gives Claude seven read-only tools to query a pre-built semantic index of your codebase without grepping or re-parsing. You commit a .codeindex directory alongside your code, then search for symbols by name or signature, list all functions in a file, find callers or callees of a method, and search comments or docstrings separately from code. Handles Python, TypeScript, Rust, Go, and eight other languages using tree-sitter grammars. Auto-discovers git repos in monorepos and mounts dependency indexes so you can query across package boundaries. Useful when you want Claude to navigate a large codebase structurally instead of burning tokens on trial-and-error file reads.
