rtk-ai/rtk Trends at 48,258 Stars — Rust CLI Proxy Cuts AI Coding Agent Token Consumption 60-90% With Zero Dependencies

GitHub·high signal

RTK (Rust Token Killer) is a single-binary CLI proxy that intercepts common dev commands (git status, ls, etc.) and compresses their output before it reaches your LLM context, dropping typical 30-minute Claude Code sessions from ~150K tokens to ~45K. It supports transparent auto-rewrite hooks for 12 AI coding tools including Claude Code, Cursor, Codex, and Gemini CLI with under 10ms overhead. For anyone paying per-token or hitting context limits, this is the most practical cost-reduction tool in the agentic coding ecosystem — 48,258 stars and growing fast.
