rtk: A Rust CLI Proxy Tool that Reduces LLM Token Consumption by 60-90%

rtk is a lightweight, Rust-based CLI proxy tool designed to reduce LLM token consumption in development scenarios. By filtering and compressing command outputs before they enter the LLM context, it saves 60% to 90% of tokens for common development commands with an added latency of under 10 milliseconds. With zero external dependencies, this project is ideal for developers heavily relying on AI-assisted programming.
