A CLI proxy that compresses command outputs (cargo test, git status, etc.) before they reach the LLM context window, reducing token consumption by 60-90%.

Market Position

RTK positions itself as the leading 'token killer' for CLI-based AI agents, competing with native optimizations in tools like Claude Code by being model-agnostic and more aggressive in compression.
