Workflow tracking is active for vv-managed review loops. For tracked subagents (`vv-implementer`, `vv-spec-reviewer`, `vv-code-reviewer`): 1. Open work items first with `work_item_open`. 2. Reuse the returned `VVOC_WORK_ITEM_ID`. 3. Put that header as the first line in tracked subagent prompts. 4. Prefer lightweight XML-like tagged assignment bodies after the header, such as ``, ``, ``, and ``. 5. Treat `NEEDS_CONTEXT` as a hard stop. 6. Use `work_item_list` to inspect workflow state before retrying. 7. Avoid free-form review loops without explicit work-item identity. Use `work_item_close` explicitly when a work item is complete.
