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 commit. ## 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 already settled, numbering each question and providing a recommended answer per round. - Fact-Finding via Sub-Agents: Dispatches sub-agents to look up facts from the filesystem or tools instead of asking you for information it can find itself. - Use Case: Before starting a migration project, use this Skill to grill yourself on the plan; it will surface unanswered questions about rollback strategy, data validation, and sequencing across multiple rounds until nothing is silently assumed. ## Quick Start Ask the AI to grill you on your plan for the upcoming product launch and answer each numbered round of questions until the frontier is empty.
