What problem does it solve? Plans and designs often contain silently assumed decisions that surface as costly surprises later. This Skill runs a structured interview that maps every decision as a design tree and asks all currently answerable questions in batched rounds, so nothing is left unexamined before work begins. ## Core Features & Use Cases - Design tree mapping: Models every decision as a branch, tracking which questions are blocked by unsettled prerequisites. - Frontier-based rounds: Asks the entire answerable frontier in one numbered round with recommended answers, then recomputes the frontier after each reply. - Autonomous fact-finding: Dispatches sub-agents to look up facts from the filesystem or tools instead of asking the user for anything discoverable. - Use Case: Before implementing a new feature, run the interview to surface every open design decision — data model, API shape, error handling — answering them round by round until the frontier is empty and the plan is fully specified. ## Quick Start Ask the assistant to grill you on your plan or design until every decision is settled and nothing is silently assumed.
