rtk
About rtk
rtk is a command-line proxy designed to reduce token consumption when working with large language models (LLMs) during development tasks. It filters and compresses command outputs before they reach the LLM context, achieving 60-90% reduction in token usage. The tool supports over 100 common developer commands and adds less than 10ms overhead per operation.
Built as a single Rust binary with zero dependencies, rtk integrates with various AI coding tools like Claude Code, Gemini CLI, and Cursor. It works by rewriting shell commands through hooks or plugin APIs, automatically applying optimization strategies without requiring manual intervention.
The tool provides specialized handling for git operations, test runners, linters, and package managers. It supports multiple platforms including Linux, macOS, and Windows (via WSL for full functionality). Installation options include Homebrew, direct download of pre-built binaries, or compilation from source.
