About rtk
rtk is an Apache 2.0 Rust CLI proxy that sits between an AI coding agent and the shell, filtering and compressing command output so 60 90% fewer tokens reach the model, and it is built for developers running agentic coding tools such as Claude Code, Cursor, or Codex against real repositories.
