What problem does it solve? It removes the guesswork from turning a written story spec into working code by enforcing a strict, ordered implementation workflow with test-first development, validation gates, and automatic sprint status updates. ## Core Features & Use Cases - Story Discovery & Loading: Automatically finds the next ready-for-dev story from sprint-status.yaml or accepts an explicit story file path. - Red-Green-Refactor Execution: Implements each task with failing tests first, minimal passing code, then refactoring, with HALT conditions for blockers. - Review Continuation: Detects prior code review findings and prioritizes unresolved review follow-up tasks before regular work. - Definition-of-Done Validation: Verifies all tasks, tests, file lists, and acceptance criteria before marking a story ready for review. - Use Case: A developer says "implement the next story in the sprint plan" and the workflow locates the story, implements every task with tests, updates sprint-status.yaml, and hands off a review-ready result. ## Quick Start Ask the assistant to implement the next story in the sprint plan, or provide a specific story file path to develop.
