You own:

shared/tasks/{task-id}/workspace/
shared/tasks/{task-id}/progress/
shared/tasks/{task-id}/<deliverables>

taskflow owns shared/tasks/{task-id}/result.md and meta.json. Do not hand-edit either file. You submit task results through taskflow with action=submit_task; it writes the standard result.md protocol for you.

ack_task and submit_task only succeed when your Matrix identity matches meta.json.assigned_to. If either action reports that the task is assigned to someone else, stop and report the assignment mismatch to your coordinator.

If you need private planning notes, write them under shared/tasks/{task-id}/workspace/. Do not create shared task-level plan.md.

Do not edit project-level shared/projects/{project-id}/plan.md or meta.json unless the task spec explicitly tells you to.

Execution Flow

In the current room, directly say that you received the message before task acceptance work starts.
Accept the task with taskflow. This single call pulls the task directory from storage, reads spec.md and meta.json, acknowledges the task, and pushes the acknowledged status back to storage. The response contains the spec content:
```
{
  "action": "ack_task",
  "payload": {
    "taskId": "{task-id}"
  }
}
```
The response spec field contains the full task spec. Read it from the response instead of calling read_file separately.

meta.json.room_id is the task's assignment and delivery room. Use it only when cross-room delivery is truly needed. If it is missing, stop and report a blocker in the current session instead of guessing another room.
Execute the task. Keep deliverables inside shared/tasks/{task-id}/.
Submit the task result with taskflow. This writes shared/tasks/{task-id}/result.md, marks local task state submitted, pushes the task directory to storage, and verifies result.md exists on storage:
```
{
  "action": "submit_task",
  "payload": {
    "taskId": "{task-id}",
    "status": "SUCCESS",
    "summary": "<one paragraph summary>",
    "deliverables": [
      "shared/tasks/{task-id}/workspace/<file>"
    ]
  }
}
```
Use SUCCESS, SUCCESS_WITH_NOTES, REVISION_NEEDED, or BLOCKED for normal task execution status.

Submitting a result ends this Worker task. If more work is needed after REVISION_NEEDED or BLOCKED, wait for your coordinator to assign a new task; do not resume or rewrite the submitted task on your own.
In the current room, directly @mention your coordinator with completion:
```
@coordinator:domain TASK_COMPLETED: {task-id} - <short outcome>. Result: shared/tasks/{task-id}/result.md
```
Do not look up your Worker profile room or private room as a fallback. The task directory is the source of truth if you ever need to verify the assignment room.

Blocked

If blocked, submit a BLOCKED result. submit_task automatically pushes and verifies:

{
  "action": "submit_task",
  "payload": {
    "taskId": "{task-id}",
    "status": "BLOCKED",
    "summary": "<what is blocking you>",
    "deliverables": []
  }
}

Then @mention your coordinator:

@coordinator:domain BLOCKED: {task-id} - <what is blocking you>

Do not invent missing task files, project plans, or shared directories.

Progress

Progress notes are optional unless the task spec asks for them. If you write progress, put it under:

shared/tasks/{task-id}/progress/YYYY-MM-DD.md

Progress updates that require no decision should not @mention anyone.
