What problem does it solve? Long, filler-heavy AI responses waste tokens and slow down reading. This Skill cuts output token usage by roughly 65-75% by stripping articles, pleasantries, and hedging while keeping every technical detail, code block, and error string exact. ## Core Features & Use Cases - Six intensity levels: lite, full (default), ultra, plus three Classical Chinese (wenyan) variants for up to 80-90% character reduction. - Session persistence: the mode stays active across all turns until explicitly stopped with "stop caveman" or "normal mode". - Auto-clarity rule: 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, enable full mode so every explanation arrives as terse fragments like "Bug in auth middleware. Token expiry check use < not <=", cutting reading time without losing precision. ## Quick Start Ask the AI to enable caveman mode by saying "use caveman mode" or invoking /caveman, then continue your conversation normally.
