Caveman is a Claude/multi-agent plugin that rewrites AI responses in ultra-compressed style (caveman-speak), cutting output tokens by 65% while preserving technical accuracy. The project gained 1043 GitHub stars and 1.4K forks on detection, signaling rapid adoption among developers seeking to reduce LLM API costs.

One insight: Zero monetization evidence and no structural moat—this is pure open-source tooling that competes on virality, not revenue, making it a poor studio wedge target despite strong traction and trivial build time.
