Execute the implementation plan, track progress in the task backend. Use after planning.

groove work exec Outcome Code, tests, and artifacts are written per the plan. The work task is created/updated in the backend with progress notes. Output is ready for review. Acceptance Criteria Implementation matches the plan from /groove work plan Work task body tracks progress with dated notes Output (code, tests, docs) is complete enough to hand off to /groove work review Stage task created/updated in backend: YYYY MM DD, Work Constraints Read tasks.backend from .groove/index.md to determine backend If no prior plan exists, warn the user and ask them to confirm scope before proceeding Append progress notes to task body as work proceeds — do not overwrite Do not mark task as completed during this stage — that happens after review Create stage task via /groove utilities task create if tasks.backend != none (title YYYY MM DD, Work )
