Stages 1-2 of the Software Factory - a relentless one-question-at-a-time interview that sharpens a loose idea into a brief (factory/BRIEF.md), then breaks the brief into a staged, dependency-ordered task list (factory/PLAN.md). This is the skill that CREATES the task list. Built for semi-technical and non-technical builders - plain language, a recommendation with every question. Use standalone or via /factory. Triggers - "plan my build", "turn this idea into tasks", "factory plan".
