sdd-implement

Automate plan execution by processing exploration and plan data to implement tasks in waves, honoring a Batch Assignment Table to run ordered and parallel batches, then validating quality gates after each batch completes.

Track progress during code change execution by updating [ ] to [X] markers in plan.md as tasks complete, providing clear traceability and status reporting for artifacts and next steps across each wave-scoped batch.

Quality gates validate checkpoints after each batch during code change orchestration, halting execution immediately upon failure to prevent regressions and ensure reliable deliveries before proceeding to the next wave.

You must provide `.sdd/{change-name}/exploration.md` and `.sdd/{change-name}/plan.md` files to run automated plan execution, as the system reads these to gather context, perform changes via Edit and Write tools, and guide implementation.

You can run parallel tasks when automating a software engineering plan if the Batch Assignment Table explicitly allows it, executing wave-scoped batches in order while maintaining safe execution and quality gate validation.

When a quality gate validation fails during plan execution, the system halts the batch-driven orchestration immediately to prevent regressions, ensuring no further tasks execute until the checkpoint failure is resolved.
