CS – indexless code search that understands code, comments and strings

Codespelunker (cs) is a CLI code search tool that combines the speed of command-line tools with intelligent relevance ranking. Unlike grep or ripgrep, it parses code structure on-the-fly to distinguish between code, comments, and strings, ranking matches by relevance using BM25 scoring. It includes features like complexity gravity to surface implementation files over interfaces, multiple search interfaces including TUI and HTTP modes, and MCP server support for LLM integration.
