pi-caveman-mode

When active, it injects a style instruction into pi's system prompt so replies become terse, blunt, and low-filler.

What it does

• Turns on automatically at session start
• Adds a caveman-style response rule to the agent system prompt
• Lets you toggle mode from chat input

Commands inside pi

• caveman mode or start caveman → enable
• normal mode or stop caveman → disable
