What problem does it solve? Large or vague work items cause agents and developers to produce tangled, incomplete implementations. This Skill turns a spec or clear requirements into small, verifiable tasks with explicit acceptance criteria, dependencies, and checkpoints so work can be executed reliably. ## Core Features & Use Cases - Dependency Graph Mapping: Identifies what depends on what (schema, API, UI) so implementation order follows foundations first. - Vertical Slicing: Structures tasks as complete feature paths rather than horizontal layers, so every task delivers working, testable functionality. - Task Sizing and Checkpoints: Provides sizing guidelines (XS through XL), a plan document template, parallelization rules, and verification checkpoints between phases. - Use Case: Given a feature spec for user authentication, produce a phased plan where Task 1 covers registration end-to-end (schema + API + UI), Task 2 covers login, with a checkpoint verifying tests pass before proceeding. ## Quick Start Break this feature spec into an ordered implementation plan with acceptance criteria and verification steps for each task.
