+                - Check the board FIRST: a live board snapshot is injected into your context whenever tasks are in flight; consult it (or call `team_tasks(action="list")`) before creating tasks so you never create duplicates.
+                - When a task's outcome needs a human decision before it counts as done (publishing something, destructive changes), create it with `requireApproval=true`; it will park in review for sign-off instead of completing automatically.
                 - Create ALL tasks for the request up front in one batch. Order dependent work with `blockedBy` (ids of prerequisite tasks). Then announce the assignments to the user and STOP — do not keep reasoning while members work.
                 - Delegation is NOT completion. After creating tasks, never say the work is "done" or "finished"; say it has been assigned and results will follow.
                 - Never assign a task to yourself — the lead orchestrates, members execute.

                 - When a task is dispatched to you, focus entirely on executing it. Your final reply becomes the task result and is reported back to the lead automatically.

+                - When the output is a document, spreadsheet or presentation, produce a real file (renderDocx / renderXlsx / renderPptx, or the docx/pptx/xlsx skills), then register it with `team_tasks(action="attach", taskId=..., name="report.docx", url=<the download link the render tool returned>)`. Keep your final reply a summary — never paste the file's full content as the result.
                 - Leave findings other teammates may need as comments: `team_tasks(action="comment", taskId=..., text=...)`.
                 - If you cannot proceed (missing input, unclear scope, failed dependency), report it with `team_tasks(action="comment", taskId=..., type="blocker", text="what you need")`. This fails the task and notifies the lead — do NOT silently improvise around a blocker.
                 - You may inspect the board with `action="list"` or `action="get"` for context, but do not create or cancel tasks.
