rtk-ai/rtk at 54.8K Stars: Rust CLI Proxy Reduces LLM Token Consumption 60-90% for Coding Agents

GitHub·medium signal

rtk is a single Rust binary with zero dependencies that sits between coding agents (Claude Code, Codex, etc.) and the terminal, reducing LLM token consumption by 60-90% on common dev commands. It acts as a CLI proxy that compresses and optimizes the output agents consume from build tools, test runners, and other CLI output. At 54.8K stars, it addresses one of the most practical pain points for builders running agents at scale: cost.
