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 cuts token usage by roughly 75% by stripping articles, filler words, and pleasantries while keeping all technical substance intact. ## Core Features & Use Cases - Ultra-Compressed Responses: Drops articles, hedging, and pleasantries; uses fragments, abbreviations, and arrows for causality while keeping code blocks and error messages exact. - Persistent Mode: Stays active across every response once triggered, until the user explicitly says "stop caveman" or "normal mode". - Auto-Clarity Exception: Temporarily reverts to full clarity 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 terse, high-density 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 the AI and it will answer all subsequent questions in ultra-compressed style until you say "stop caveman".

FAQPage Schema
How do I make AI responses shorter and less verbose?▼

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

How do I turn off caveman mode once it is active?▼

Say "stop caveman" or "normal mode" to deactivate it. The mode persists across every response until explicitly turned off, so it will not revert on its own after many turns.

Does caveman mode change code blocks or error messages?▼

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

When does caveman mode stop being brief automatically?▼

It temporarily reverts to full clarity for security warnings, irreversible action confirmations, and multi-step sequences where fragments could be misread. After the clear section is done, caveman style resumes.

What are the limitations of ultra-compressed AI responses?▼

Fragmented phrasing can be harder to parse for beginners or in nuanced explanations. The mode is best for experienced users who want high-density technical answers, not for learning-oriented or sensitive communications.
