What problem does it solve? Plans and decisions often contain hidden assumptions and unexplored branches that only surface after execution begins. This Skill interviews you relentlessly about a plan, decision, or idea, mapping it as a design tree so every dependent decision is examined before you act. ## Core Features & Use Cases - Design Tree Mapping: Models your plan as a tree where every decision branches into the decisions that depend on it. - Frontier-Based Rounds: Asks only the questions whose prerequisites are settled, numbering each one and providing a recommended answer so you can respond quickly. - Autonomous Fact-Finding: Dispatches sub-agents to look up facts from the environment instead of asking you for anything it could find itself. - Use Case: Before committing to a system architecture, have the Skill grill you on scaling, data model, deployment, and failure handling until no assumption is left silently made. ## Quick Start Grill me on my plan to migrate our monolith to microservices.
