What problem does it solve? Design and requirements conversations often dive into implementation detail before the high-level shape is agreed, leaving teams with deep answers to the wrong questions. This Skill runs a structured interview that covers one level of detail completely — decomposing a system into parts, defining scope, and pinning down what is wanted and explicitly not wanted — before any deeper discussion begins. ## Core Features & Use Cases - Fixed-altitude interviews: Sweeps the whole surface at one level (A0 Intent through A4 Ready) and parks any question that belongs deeper, with a labeled parked list. - Strawman-first sweep: Drafts a complete decomposition with best guesses filled in so the human reacts to a concrete proposal instead of composing from a blank page. - Standing readbacks and paper trail: Ends every round with a numbered agreed/open/parked summary and writes glossaries and ADRs as decisions crystallise. - Use Case: When starting a new service whose requirements are vague, run a survey at A1 Parts to agree the component list, what each part owns, and what is explicitly out of scope, before any prototyping or implementation. ## Quick Start Ask the agent to run a survey at A1 Parts to decompose your system idea into components and agree scope before writing any code.
