What problem does it solve? Plans, designs, and product ideas often contain vague assumptions, contradictions, and untested hypotheses that surface too late. This Skill relentlessly interviews you in Japanese, round by round, until every implicit assumption is resolved and a shared understanding is reached. ## Core Features & Use Cases - Round-based frontier questioning: Groups all currently answerable questions into a single numbered round with recommendations, deferring dependent questions to later rounds. - Rigorous challenge of vagueness: Refuses to accept answers like "somehow" or "roughly", challenges assumptions, contradictions, and wishful thinking, and never starts implementation before agreement. - Fact vs. decision separation: Investigates codebase facts and reference materials itself, asking you only for decisions that require judgment. - Use Case: You want to build a new authentication system with JWT. The Skill batches questions about session management, refresh tokens, logout, and security edge cases into one round, each with a recommended answer, and pushes back on any vague replies. ## Quick Start Ask the AI to grill you on your project plan or design idea using the personal-grill-me skill until you reach a shared understanding.
