Caveman

Cuts your token usage by about 75% by having Claude respond like a technically accurate caveman. No articles, no filler words, just the substance. It has intensity levels from lite (just removes pleasantries) to ultra (aggressive abbreviation) to wenyan modes that use classical Chinese grammar for maximum compression. Good for when you're burning through tokens on repetitive tasks or long coding sessions. It smartly breaks character for security warnings and destructive operations, then snaps back. The persistence mechanism is solid, it won't drift back to verbose mode after a few turns like some prompt hacks do. Honestly kind of hilarious to use while still being genuinely useful for API costs.
