codespelunker - CLI code search tool that understands code structure and ranks results by relevance. No indexing required with CLI, TUI, MCP and HTTP support.
codespelunker, invoked as cs, is a code-search tool that parses repositories to distinguish executable code from comments and strings, then ranks matches by relevance. Developers and AI agents use it to locate implementations and useful snippets through a CLI, terminal interface, or HTTP service without maintaining a search index. The catalogue instruction helps coding agents use its structured search capabilities.
