What problem does it solve? Breaking a vague roadmap topic into well-sized, adoption-focused milestones and tasks is hard to do consistently, especially when the work must align with an existing project board's conventions, priorities, and anti-goals. ## Core Features & Use Cases - Adoption-lens decomposition: Evaluates each candidate against mission pillars, target adopters, friction removed, and observable signals before proposing it. - Board-aware planning: Reads the existing .pm board state, completed milestones, and repository documentation to avoid duplicating shipped work. - Sizing and quality gating: Applies the canonical sizing rule and milestone quality gate, routing undersized work to inbox notes and rejecting non-meaningful milestones. - Use Case: A maintainer wants to plan "improve onboarding for new contributors" — the skill reads the board, decomposes the topic into sized milestones with dependencies, and emits a text proposal plus the exact /pm commands to materialize it. ## Quick Start Invoke /pm-brainstorm with a topic such as "improve time-to-first-ledger for new users" to receive a prioritized milestone proposal and the /pm commands to create it.
