描述
Clarify ambiguous or conflicting requests by researching first, then exhaustively interrogating assumptions, constraints, dependencies, trade-offs, edge cases, and failure modes before any planning or implementation. Use when prompts say "$grill-me" or "grill me", ask hard questions, request relentless interrogation, pressure-test assumptions, clarify scope or requirements, define success criteria, or request product/system-design decisions before implementation. Respond in the user's language. Stop before implementation.
