What problem does it solve? Turning a plan, spec, or PRD into actionable work items is hard: horizontal layer-by-layer tickets create dependencies and nothing is demoable until the end. This Skill decomposes source material into thin vertical slices that each cut through all layers and can be implemented, tested, and merged independently. ## Core Features & Use Cases - Vertical Slice Decomposition: Converts PRDs and specs into tracer-bullet issues that are each demoable on their own, with HITL/AFK typing and explicit dependency ordering. - Deep Module Awareness: Respects module boundaries from the PRD, ensuring deep modules are built as isolated early slices and thin binaries compose them afterward. - Interactive Refinement: Interviews the user one question at a time about scope, blockers, user stories, and acceptance criteria before publishing. - Use Case: After writing a PRD for a new service, ask the assistant to break it into issues; you receive a numbered, dependency-ordered issue set with acceptance criteria and a Mermaid dependency graph grouped by phase. ## Quick Start Ask the assistant to break the attached PRD into vertical-slice implementation issues with dependencies and acceptance criteria.
