Relentless one-question-at-a-time interrogation that drives every unresolved decision out of a plan, design, or fuzzy idea BEFORE prompt-transform reformats it and any code or formal plan is written. USER-INVOKED ONLY — triggers when the user types /grill, /grill <topic>, says "grill me", "grill this plan/design", "stress-test this", "interrogate me on X", "poke holes in this", or "what am i missing". Walks the decision tree branch by branch via AskUserQuestion (one question, recommended answer first), resolves dependencies in order, pins overloaded terms, surfaces code-vs-claim contradictions from the live codebase (codegraph-elai + elai.map + ELAI-FEATURE-MAP), routes unverified external claims to grounding, and hands a resolved-decisions block to prompt-transform / planning-workflow / idea-intake. Read-only on code, works in any FSM state, never auto-fires, never transitions the FSM.

Apple's approach to interface design and fluid, physical motion, translated for the web. Use when building or reviewing gesture-driven UI, spring animations, drag/swipe/sheet interactions, momentum and interruptible transitions, translucent materials and depth, typography (optical sizing, tracking, leading), reduced-motion, or the design foundations (feedback, spatial consistency, restraint) behind Apple-style interfaces.
