SYSTEM DOCUMENTATION & REQUIREMENTS

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.

FAQPage Schema
How do I reduce token usage in AI chat responses?

Enable caveman mode by saying "use caveman" or invoking /caveman. The assistant drops articles, filler, and pleasantries, cutting output tokens by roughly 65-75% while keeping code, error strings, and technical terms exact.

How do I turn off caveman mode?

Say "stop caveman" or "normal mode" and the assistant reverts to standard prose. The mode otherwise persists for the entire session and does not drift back on its own.

What compression levels does caveman mode support?

Six levels: lite (full sentences, no filler), full (default, drops articles), ultra (abbreviations and arrows), and wenyan-lite, wenyan-full, wenyan-ultra for Classical Chinese compression up to 80-90% character reduction.

Does caveman mode change code blocks or error messages?

No. Code blocks, function names, API names, and error strings are never abbreviated or altered. Only surrounding prose is compressed, so technical accuracy is fully preserved.

When does caveman mode stop compressing automatically?

It drops to normal prose for security warnings, irreversible-action confirmations, multi-step sequences where fragments risk misreading, and when you repeat a question. Compression resumes after the clear portion.
