Activation
This is the description your AI agent reads to decide when to run this skill — the better it matches your request, the more reliably it fires.
Token compression skill. Use when: context window is filling up, on long-running multi-session tasks, when Manager explicitly says 'caveman mode', or when user needs faster/cheaper agent responses. Reduces output tokens 65–75% by switching to telegraphic prose. Three intensity levels: lite, full, ultra.Key capabilities
- →Compress output
- →Reduce token spend
- →Adopt telegraphic prose
- →Manage context window
How it works
Uses three intensity levels to reduce token usage by 65-75% through telegraphic writing.

About caveman
Reduces output tokens by adopting telegraphic prose across three intensity levels (lite, full, ultra) to manage context window pressure.

Limitations
- →Never compress code or security findings
How it compares
Specifically designed for token-constrained environments and long-running sessions.
