What problem does it solve? Large or vaguely defined work items cause agents and developers to start coding without a plan, producing tangled implementations, missed dependencies, and rework. This Skill turns a spec or clear requirements into an ordered list of small, verifiable tasks with explicit acceptance criteria, dependencies, and checkpoints. ## Core Features & Use Cases - Dependency-aware task ordering: Maps the dependency graph (schema → API → UI) and orders tasks bottom-up so foundations are built first. - Vertical slicing guidance: Splits work into complete feature slices rather than horizontal layers, so every task delivers working, testable functionality. - Task sizing and checkpoints: Provides XS–XL sizing rules, a plan document template, and verification checkpoints after every 2-3 tasks. - Use Case: Given a spec for a new user-management feature, produce a phased plan where Task 1 delivers account creation end-to-end, Task 2 delivers login, each with acceptance criteria, verification commands, and a human review checkpoint before proceeding. ## Quick Start Ask the agent to read the spec for your feature and produce a phased implementation plan with sized tasks, acceptance criteria, and checkpoints before writing any code.
