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.
