Rtk Token Optimizer

What This Skill Does

The RTK Token Optimizer is a specialized CLI proxy designed to solve the problem of excessive LLM context consumption during software development. By leveraging a high-performance Rust binary, it intercepts standard developer commands—such as git operations, file listings, and test suite results—and compresses the textual output before it is passed to your AI agent. This tool effectively reduces the token overhead of common terminal tasks by 60-90%, allowing developers to maintain larger codebases within their AI context windows without hitting capacity limits or incurring unnecessary latency.

Installation

Installation is straightforward via Homebrew for macOS users: brew install rtk. For Linux or generic Unix-like environments, you can use the installation script: curl -fsSL https://raw.githubusercontent.com/rtk-ai/rtk/refs/heads/master/install.sh | sh. If you are a Rust developer, you can install from source using cargo install --git https://github.com/rtk-ai/rtk. After installation, run rtk init -g to set up the global hooks that enable automatic command wrapping for tools like Claude Code, Cursor, and Windsurf.

Use Cases

This skill is ideal for AI-assisted coding workflows where the AI agent frequently executes git status, ls -R, or long grep searches. By using rtk ls or rtk grep instead of standard commands, you ensure that the AI receives a cleaned, concise representation of your project state. It is particularly valuable for developers working with large repositories where traditional directory tree outputs or massive diffs would otherwise consume hundreds of tokens unnecessarily.

Example Prompts

1. "OpenClaw, please optimize my workflow by installing the rtk token optimizer globally and configuring it for use with my current Cursor environment."
2. "I'm hitting context window limits; can you use rtk commands to read my source files and run git status with the token-optimized output?"
3. "Show me how to verify my current token savings after setting up the rtk hook using the command-line interface."

Tips & Limitations

Note that RTK operates by intercepting Bash tool calls. Because Claude Code's native, non-shell tools like 'Read' or 'Glob' bypass the shell, you must explicitly use shell equivalents or rtk-prefixed commands to benefit from the compression. Always verify your installation with rtk --version after restarting your AI tool to ensure the environment path is correctly loaded.
