Instead of reading entire files, agents ask structural questions like: \"who calls this function\", \"what breaks if I change it\", \"what's unused\", and get precise, AST-verified answers. UCN parses JS/TS, Python, Go, Rust, Java, and HTML inline scripts with tree-sitter, then exposes 28 navigation commands as a CLI tool, MCP server, or agent skill.","category":"development","tags":[],"official":false,"stars":1,"transport":"stdio","install":[{"cmd":"npx -y ucn","imports":[]}],"tools":[{"name":"ucn","description":"Universal Code Navigator - find symbols, trace callers, check impact, pick tests, extract code, and spot dead code from the terminal.
