What problem does it solve? Breaking a large epic into sprint-ready user stories is slow and error-prone: teams often create horizontal slices, duplicate existing stories, or skip quality checks. This Skill automates epic decomposition with vertical slicing, INVEST validation, and idempotent story creation in your PM tool. ## Core Features & Use Cases - Vertical Slicing & INVEST Validation: Identifies story candidates from workflow steps, CRUD operations, business rules, and user roles, then validates each against INVEST criteria before creation. - Idempotent Story Creation: Detects existing stories linked to the epic and creates only missing ones via the composed /capability-write-issue skill, so re-runs never duplicate work. - Coverage Reporting: Validates that stories cover the full epic scope and reports totals, points, and next steps. - Use Case: A product manager selects Epic #42 (user onboarding). The Skill proposes five story candidates, skips two that already exist, validates the rest against INVEST, creates them in the PM tool, and reports 13 total estimated points. ## Quick Start Ask the AI to break down epic #42 into user stories using vertical slicing and INVEST validation.
