rtk - Rust Token Killer

High-performance CLI proxy to minimize LLM token consumption.

Website | GitHub | Install

rtk filters and compresses command outputs before they reach your LLM context, saving 60-90% of tokens on common operations.

⚠️ Important: Name Collision Warning

There are TWO different projects named "rtk":

1. ✅ This project (Rust Token Killer) - LLM token optimizer

   • Repos: rtk-ai/rtk
   • Purpose: Reduce Claude Code token consumption

2. ❌ reachingforthejack/rtk - Rust Type Kit (DIFFERENT PROJECT)

   • Purpose: Query Rust codebase and generate types
   • DO NOT install this one if you want token optimization

How to verify you have the correct rtk:

rtk --version   # Should show "rtk 0.22.2"
rtk gain        # Should show token savings stats

If rtk gain doesn't exist, you installed the wrong package. See installation instructions below.

Token Savings (30-min Claude Code Session)

Typical session without rtk: ~150,000 tokens With rtk: ~45,000 tokens → 70% reduction

| Operation | Frequency | Standard | rtk | Savings | |-----------|-----------|----------|-----|---------| | / | 10× | 2,000 | 400 | -80% | | / | 20× | 40,000 | 12,000 | -70% | | / | 8× | 16,000 | 3,200 | -80% | | | 10× | 3,000 | 600 | -80% | | | 5× | 10,000 | 2,500 | -75% | | | 5× | 2,500 | 500 | -80% | | | 8× | 1,600 | 120 | -92% | | / | 5× | 25,000 | 2,500 | -90% | | | 3× | 3,000 | 600 | -80% | | | 4× | 8,000 | 800 | -90% | | | 3× | 6,000 | 600 | -90% | | | 3× | 900 | 180 | -80% | | | | | | |
