rtk

rtk is a high-performance command-line interface (CLI) proxy designed to significantly reduce LLM token consumption by filtering and compressing command outputs, typically achieving 60-90% savings. Implemented as a single Rust binary, it supports over 100 common CLI commands and employs four core strategies: smart filtering, grouping, truncation, and deduplication. With a transparent auto-rewrite hook for Bash commands, rtk optimizes the context provided to LLMs without altering user workflows, thereby enhancing efficiency and cost-effectiveness when interacting with AI tools.
