What problem does it solve? Plans and designs often contain hidden assumptions, unresolved dependencies, and unexamined risks that only surface during implementation. This Skill systematically interrogates a plan through structured one-at-a-time questioning until every major decision branch is resolved and the design is defensible. ## Core Features & Use Cases - Sequential Interrogation: Asks exactly one question at a time, using each answer to select the next highest-leverage unresolved question across an implicit decision tree. - Recommended Options: Presents clear answer options with a marked recommendation and reasoning, while using open-ended questions when fixed options would constrain the design space. - Comprehensive Coverage: Probes goals, users, constraints, APIs, data models, error handling, security, observability, testing, rollout, failure modes, and success criteria. - Use Case: Before writing code for a new service, ask the Skill to grill you on the architecture. It challenges vague assumptions, surfaces contradictions, and ends with a summary of the agreed design, remaining risks, and next steps. ## Quick Start Ask the assistant to grill you on your plan or design document and answer each question as it comes until the design is fully resolved.
