SYSTEM DOCUMENTATION & REQUIREMENTS

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".

FAQPage Schema
How do I reduce AI output tokens in chat responses?

Enable a compression mode like caveman, which drops articles, filler, pleasantries, and hedging from every response. It cuts output tokens by roughly 65% while keeping code, error strings, and technical terms exact.

How do I turn on caveman mode?

Invoke /caveman for the default full mode, or specify a level such as /caveman lite, /caveman ultra, or /caveman wenyan. The mode persists for the whole session until you say "stop caveman" or "normal mode".

Does caveman mode change code blocks or error messages?

No. Code blocks, function names, API names, CLI commands, and exact error strings are always preserved verbatim. Only the surrounding prose is compressed; technical content stays exact.

Can caveman mode reply in languages other than English?

Yes. It preserves the user's dominant language, compressing style rather than translating. It also offers three Classical Chinese (文言文) levels achieving 80-90% character reduction.

When does caveman mode stop compressing responses?

It automatically drops to normal prose for security warnings, irreversible-action confirmations, ambiguous multi-step sequences, and when the user repeats a question. Compression resumes after the clarity-critical part is done.
