Summary
RTK is an open-source terminal output compressor designed specifically for AI coding workflows. It intercepts and compresses terminal output to save ~90% on API token costs.
Problem it solves
- When AI tools like Claude Code run tests/compilation in the background, they generate massive amounts of whitespace, comments, duplicate logs, and error messages
- This junk data fills up the context window, wastes tokens, and causes the AI to “forget” conversation history
How it works
- Intercepts all terminal output with <10ms latency
- Applies filtering, summarization, and deduplication strategies
- Reduces token volume by ~90%
Installation
- Install via Cargo from the official GitHub repo
- One-click global hook initialization that auto-rewrites 100+ common commands
Security warnings
- There’s a name-conflict package on crates.io — must specify the official GitHub source when installing
- Terminal logs may contain passwords or API keys — recommend setting up sensitive keyword filtering
