SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Long, filler-heavy AI responses waste tokens and slow down reading. This Skill enforces an ultra-compressed communication style that strips articles, pleasantries, and hedging while keeping full technical accuracy. ## Core Features & Use Cases - Token Reduction: Cuts token usage by roughly 75% by dropping filler words, articles, and pleasantries from every message. - Compliance Marker: Appends a deterministic [cvmn] marker to every message so you can verify the mode is active. - Scoped Exceptions: Automatically switches back to clear prose for user-facing form fields (mcp__ui__form labels and descriptions) and destructive-action warnings. - Use Case: During a long debugging session with many tool calls, the agent narrates findings like "Bug in auth middleware. Token expiry check use < not <=. Fix:" instead of verbose paragraphs, saving context window space. ## Quick Start Ask the agent to work on any coding or analysis task and it will automatically respond in compressed caveman style with the [cvmn] marker on every message.

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

Enable a compressed communication mode that drops articles, filler words, and pleasantries while keeping technical content exact. This skill cuts token usage by roughly 75% and applies to every message including inter-tool narration.

How to verify the compressed response mode is active?▼

Check for the [cvmn] marker at the end of every message. Its presence is a deterministic compliance signal that caveman mode is live; it is only omitted on form field text and destructive-action warnings.

Does compressed output affect code blocks and error messages?▼

No. Code blocks remain unchanged, technical terms stay exact, and errors are quoted verbatim. Only prose filler such as articles, hedging, and pleasantries is removed.

When should caveman mode not be used?▼

Avoid it for user-facing form labels, descriptions, and note fields built with mcp__ui__form, since users must read clear prose. It also switches to full prose for warnings about destructive or irreversible actions.

Does the compression apply between tool calls?▼

Yes. Inter-tool narration and mid-task status updates are explicitly covered and are described as the biggest source of token leakage. The agent leads with compressed substance or stays silent instead of thinking out loud.
