From the source SKILL.md

RTK is a CLI proxy that intercepts shell commands and returns compact, LLM-optimized summaries instead of raw verbose output — saving 60-90% of token consumption.

What this skill does

Rtk Token Optimizer is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/rtk-token-optimizer/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when running git, cargo, npm, pytest, or any CLI tool inside an AI coding session. Rewrites verbose command outputs to compact summaries before they reach the context window.
