Rtk

This skill helps you install and configure RTK (Rust Token Killer), a CLI proxy that rewrites verbose shell commands into token-optimized output before they hit your AI agent. It handles the common trap of installing the wrong `rtk` package via Cargo, walks through the right init mode for Claude Code, Codex, Gemini, Cursor, or OpenCode, and explains when to use direct `rtk` wrappers instead of relying on shell hooks. The setup matters because built-in file tools bypass hooks entirely, so you need to know when `rtk read` or `rtk grep` saves tokens that automatic rewriting misses. Useful if you're burning context on giant git diffs or test output.

rtk - Rust Token Killer for AI Coding Agents

Keyword: rtk · rust token killer · rtk init · rtk gain

The target repository is the akillness/rtk fork of rtk-ai/rtk. The fork tracks upstream code, while the bundled install.sh still downloads release artifacts from rtk-ai/rtk.

RTK is a high-performance CLI proxy that rewrites common shell commands into token-optimized equivalents before their output reaches an AI agent. Use this skill to verify the right RTK binary, install or repair it, choose the correct rtk init mode for the user's agent, and fall back to direct rtk commands when no automatic hook exists.
