What problem does it solve? Long, filler-heavy AI responses waste output tokens and slow down reading. This Skill compresses every model response into terse caveman-style prose, cutting output tokens by roughly 65% while keeping code, error strings, and technical terms exact. ## Core Features & Use Cases - Six intensity levels: lite, full (default), ultra, plus three Classical Chinese (文言文) modes for up to 80-90% character reduction. - Persistent session mode: once activated, compression applies to every response until explicitly stopped with "stop caveman" or "normal mode". - Auto-clarity fallback: automatically reverts to normal prose for security warnings, irreversible-action confirmations, and ambiguous multi-step sequences, then resumes compression. - Use Case: During a long debugging session, invoke /caveman so every explanation arrives as short fragments like "Bug in auth middleware. Token expiry check use < not <=", saving tokens across hundreds of turns. ## Quick Start Ask the AI to enable caveman mode by saying "use caveman mode" or invoking /caveman, and all subsequent responses will be compressed until you say "stop caveman".
