What problem does it solve? It automates the disciplined execution of a development story: finding the next ready story in the sprint plan, implementing each task with tests, and updating tracking files, so developers follow a consistent, auditable workflow instead of ad-hoc coding. ## Core Features & Use Cases - Sprint Story Discovery: Automatically locates 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 following a red-green-refactor cycle, writing failing tests first and validating against acceptance criteria. - Review Continuation: Detects prior code review findings and prioritizes unresolved review follow-up tasks before continuing regular work. - Use Case: A developer says "implement the next story in the sprint plan" and the agent loads the story spec, implements all tasks with tests, updates the story file and sprint status to review, and reports a completion summary. ## Quick Start Ask the agent to dev the story at a given story file path or to implement the next ready story in the sprint plan.
