caveman

Token-compression skill + tooling

FreeCost & efficiencygithub.com

What it is

A skill that makes the agent respond in terse fragment style to cut output tokens, at four compression levels. Companion tools attack the input side: caveman-compress rewrites CLAUDE.md and memory files (~46% fewer input tokens), caveman-shrink wraps any MCP server with compressed tool descriptions. ~69k stars.

Why it earns a slot

The caveman-compress and caveman-shrink utilities are the parts worth having — they save tokens without making the agent's prose unreadable.

Know before you commit

Headline claim is 75% output reduction; the repo's own 10-task benchmark reports 65% average with a 22–87% range. And terse fragment output is genuinely harder to review.
