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.

When to use this skill

• Verify whether RTK is already installed and whether it is the correct project
• Repair the common cargo install rtk name-collision mistake
• Install RTK with Homebrew, the repository install.sh, or Cargo
• Initialize RTK for Claude Code, Codex, Gemini CLI, Cursor, Copilot, Windsurf, Cline, or OpenCode
• Explain when rtk init -g is better than local project setup
• Use direct rtk wrappers such as rtk git status, rtk read, rtk grep, rtk test, or rtk lint
• Diagnose why automatic rewriting is not happening
• Explain why built-in file tools do not pass through shell hooks and when to use direct rtk commands instead
