What problem does it solve? Plans often hide silent assumptions and unresolved decisions that only surface during implementation, causing rework and stalls. This Skill forces every open question in a plan into the open through a structured one-question-at-a-time interview, so each decision is either answered concretely or explicitly deferred with an owner and a cost. ## Core Features & Use Cases - Decision tree mapping: Maps the plan as a tree of dependent decisions, posting the full numbered question list up front and re-deriving what is askable after every answer. - Disciplined questioning: Enforces one short question per turn with two or three options and a single-reason recommendation, never asking what code search, memory, or research subagents can answer. - Managed deferrals: Every deferred decision gets an owner, a reversal cost, an unblocking plan, and a record in durable ticket state for later resumption. - Use Case: Before implementing a multi-repo feature, run a grilling session to surface the seven decisions the plan assumes, resolve five with the user, and defer two to named owners with documented fallback defaults. ## Quick Start Ask the assistant to grill you on your current plan or design so every open question is resolved or explicitly deferred before implementation begins.
