What problem does it solve? Large or vague work items stall implementation and produce tangled results. This Skill turns a spec or clear requirements into small, ordered tasks with explicit acceptance criteria, verification steps, and dependency mapping so work can start immediately and be tracked reliably. ## Core Features & Use Cases - Structured Task Breakdown: Converts requirements into tasks with acceptance criteria, verification steps, dependencies, files likely touched, and size estimates (XS through XL). - Vertical Slicing & Dependency Ordering: Maps the dependency graph and slices work into complete feature paths rather than horizontal layers, with checkpoints after every 2-3 tasks. - Plan Persistence with Conflict Safety: Saves plans to tasks/plan.md and task lists to tasks/todo.md or an external tracker (GitHub Issues, Jira, Linear, beads), and refuses to overwrite incomplete existing plans without user confirmation. - Use Case: Given a spec for a user authentication feature, produce a plan document plus an ordered task list covering schema, API, and UI slices, each independently testable. ## Quick Start Ask the AI to break the attached feature spec into an ordered task list with acceptance criteria saved to tasks/plan.md and tasks/todo.md.
