What problem does it solve? Turning a written story spec into working, tested code requires disciplined execution: finding the next ready story, loading project context, writing tests first, and tracking status. This Skill automates that entire developer workflow so a story goes from ready-for-dev to review in one continuous run. ## Core Features & Use Cases - Sprint Story Discovery: Automatically finds the next story marked ready-for-dev in sprint-status.yaml or accepts an explicit story file path. - Test-Driven Implementation: Executes each task/subtask with a red-green-refactor cycle, writing failing tests before minimal implementation. - Status & Review Tracking: Updates story checkboxes, File List, Dev Agent Record, Change Log, and sprint status, including resuming work after a code review. - Use Case: A developer says "implement the next story in the sprint plan" and the Skill loads the story spec, implements every task with tests, runs the full regression suite, and marks the story ready for review. ## Quick Start Implement the next ready-for-dev story from the sprint plan following its spec file.
