RTK (Rust Token Killer) Skill

Overview

RTK is a high-performance CLI proxy that minimizes LLM token consumption by filtering and compressing command outputs. It achieves 60-90% token savings on common development operations.

When to Use

• Before running verbose commands: git log, cargo test, bun install (or npm install)
• When context window is limited: Large projects with many files
• For cost optimization: Reduce token usage per session
• For build/test output: Only show failures, not full output

When NOT to Use

• When RTK is not installed — fall back gracefully to raw commands; do not fail or stall waiting for RTK
• When verbose output is explicitly needed for debugging (e.g., investigating a specific build warning) — use the raw command directly
• For commands where RTK's output compression would hide information needed for the current task
• For git commit, git push, or other write commands where you need to confirm the exact output
