UCN (Universal Code Navigator) is an AST-powered command-line tool designed to provide deep insights into your codebase without reading full files. By leveraging tree-sitter, it parses various programming languages (JS/TS, Python, Go, Rust, Java, HTML) to build a precise call graph and symbol table. This enables developers to understand code structure, dependencies, and execution flows, helping answer complex questions like 'who calls this function?', 'what breaks if I change this signature?', or 'what code is safe to delete?', all while running entirely locally. It offers a comprehensive suite of 28 commands for diverse code intelligence tasks and integrates seamlessly with AI agents.
