What problem does it solve? Turning a finished requirement into an actionable implementation plan is hard: teams often split work horizontally by technical layer, creating tasks that cannot be independently built, tested, or verified. This Skill decomposes requirements into fully independent vertical slices that each cut through data, logic, interface, and output layers, so every work item can be developed in parallel and validated on its own. ## Core Features & Use Cases - Vertical Slice Decomposition: Splits requirements by user behavior, data entity, scenario, or complexity, ensuring each slice spans all technical layers end to end. - AFK/HITL Classification: Labels each work item as agent-completable (AFK) or requiring human decisions (HITL), preventing agents from attempting work that needs human judgment. - Independence Validation: Checks every slice pair for shared dependencies, flags strong dependencies for merging or re-splitting, and documents fallback plans for weak ones. - Use Case: After completing requirement mining for a user management feature, use this Skill to split it into independent slices like registration, login, and password reset, each ready to enter technical design separately and be developed in parallel. ## Quick Start Ask the AI to split this requirement into independent work items that can each be developed and verified separately.
