rtk-ai: Rust CLI Proxy Compresses LLM Token Consumption 60-90% for Coding Agents, Hits 39K Stars
rtk (Rust Token Killer) is a single Rust binary that transparently intercepts Bash commands and compresses output before it reaches the agent's context window. It hooks into Claude Code, Cursor, Codex, Aider, and Windsurf — e.g., pytest -v output drops from 750 tokens to 24 tokens. By reducing CLI noise by 89%, rtk extends agent sessions up to 3x before hitting context limits. Currently trending at 39,172 GitHub stars with a Go-based alternative (snip) also emerging.
