What problem does it solve? Large cross-cutting product redesigns and multi-feature initiatives lack a shared, concrete destination, causing teams to jump into implementation without aligned decisions or a way to divide work into independently reviewable pieces. ## Core Features & Use Cases - Destination Definition: Writes or refines a master plan document under docs/master-plans/ using the repository template, recording decisions rather than implementation status. - Decision Facilitation: Resolves product decisions one at a time with the user, offering three concrete choices with a marked recommendation and supporting evidence. - Slice Decomposition: Splits the destination into small slices, each with a clear human-visible result and a clear human-doable action, plus ASCII mockups for UI composition and interaction states. - Use Case: When planning a ground-up redesign of a campaign manager UI, use this Skill to produce a master plan that records layout decisions, constraints, and acceptance criteria, then hands off individual slices for focused execution plans. ## Quick Start Ask the assistant to create a master plan for your broad product goal, for example by saying create a master plan for redesigning the dungeon map editor experience.
