SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Long, verbose AI responses waste tokens and slow down reading when you only need the technical answer. This Skill switches the assistant into an ultra-compressed communication mode that cuts token usage by roughly 75% without losing technical substance. ## Core Features & Use Cases - Persistent terse mode: Once triggered, every response stays compressed until you explicitly say "stop caveman" or "normal mode". - Technical accuracy preserved: Code blocks, error messages, and technical terms remain exact; only articles, filler, hedging, and pleasantries are removed. - Auto-clarity exception: Automatically reverts to full sentences for security warnings, irreversible action confirmations, and multi-step sequences where fragments could be misread. - Use Case: During a long debugging session, say "caveman mode" to get rapid, dense answers like "Bug in auth middleware. Token expiry check use < not <=." instead of paragraph-length explanations. ## Quick Start Say "caveman mode" or "be brief" to activate compressed responses for the rest of the conversation.

FAQPage Schema
How do I make AI responses shorter and use fewer tokens?▼

Activate caveman mode by saying "caveman mode", "be brief", or "less tokens". The assistant then drops articles, filler, and pleasantries, cutting token usage by roughly 75% while keeping all technical content intact.

How do I turn off caveman mode?▼

Say "stop caveman" or "normal mode" to revert to standard responses. The mode otherwise persists across every response in the conversation and does not drift back on its own.

Does terse mode change code blocks or error messages?▼

No. Code blocks remain unchanged and error messages are quoted exactly. Only prose is compressed; technical terms, commands, and syntax stay precise.

When does caveman mode switch back to full sentences automatically?▼

It temporarily drops compression for security warnings, irreversible action confirmations, multi-step sequences where fragment order could be misread, or when you ask for clarification. It resumes terse mode afterward.

What are the limitations of ultra-compressed responses?▼

Fragmented phrasing can be harder to parse for nuanced explanations or unfamiliar topics. For learning new concepts or reviewing risky operations, standard mode is usually clearer.
