RTK is a command-line proxy written in Rust that intercepts and optimizes developer commands to reduce LLM token consumption by 60-90%, making it useful for developers who frequently use AI coding assistants like Claude. It works as a single binary with no external dependencies, sitting between your CLI and language models to minimize unnecessary token usage while maintaining functionality. Developers would use this to lower API costs and improve performance when integrating AI tools into their development workflows.
