rtk-ai/rtk: Rust CLI Proxy Cuts LLM Token Consumption 60-90% on Dev Commands — 12,252 Stars
GitHub·high signal
RTK (Rust Token Killer) is a single-binary CLI proxy that intercepts and compresses command outputs before they hit your LLM context window. Real-world results show cargo test compressing 155 lines to 3 (98% reduction) and git status dropping 119 chars to 28 (76%). Works transparently with Claude Code, Cursor, Gemini CLI, Codex, Aider, and Windsurf with under 10ms overhead.
