What problem does it solve? Plans and design decisions often contain hidden assumptions and unresolved dependencies that surface too late. This Skill stress-tests an idea by interviewing the user relentlessly until every decision in the design tree is explicitly settled. ## Core Features & Use Cases - Design Tree Mapping: Models a plan as a tree of decisions where each choice branches into dependent sub-decisions. - Frontier-Based Rounds: Asks only the questions whose prerequisites are already settled, numbering each one and providing a recommended answer. - Fact-Finding via Sub-Agents: Dispatches sub-agents to look up environmental facts instead of asking the user for anything discoverable. - Use Case: Before implementing an ambiguous feature, run a grilling session to expose every open design question, settle them round by round, and reach a confirmed shared understanding before writing code. ## Quick Start Ask the assistant to grill you on your plan for the new feature until every design decision is settled.
