Context-diet mode for AI coding agents. Forces focused reads instead of gulping the whole repo. Cuts wasted input tokens while keeping full technical accuracy. Use when user says "keyhole", "keyhole mode", "context diet", "don't explore everything", "fewer file reads", or invokes /keyhole. Also auto-triggers when the user asks to save context/tokens on reads. Tags: agent-skills, cursor-rules, claude-code, prompt-engineering, context, llm.
