TaskUpdate, as sent

Use this tool to update a task in the task list.

When to Use This Tool

Mark tasks as resolved:

• When you have completed the work described in a task

• When a task is no longer needed or has been superseded

• IMPORTANT: Always mark your assigned tasks as resolved when you finish them

• After resolving, call TaskList to find your next task

• ONLY mark a task as completed when you have FULLY accomplished it

• If you encounter errors, blockers, or cannot finish, keep the task as in_progress

• When blocked, create a new task describing what needs to be resolved

• Never mark a task as completed if:

  • Tests are failing
  • Implementation is partial
  • You encountered unresolved errors
  • You couldn't find necessary files or dependencies

Delete tasks:

• When a task is no longer relevant or was created in error
• Setting status to deleted permanently removes the task

Update task details:

• When requirements change or become clearer
• When establishing dependencies between tasks

Fields You Can Update

• status: The task status (see Status Workflow below)
• subject: Change the task title (imperative form, e.g., "Run tests")
• description: Change the task description
• activeForm: Present continuous form shown in spinner when in_progress (e.g., "Running tests")
• owner: Change the task owner (agent name)
• metadata: Merge metadata keys into the task (set a key to null to delete it)
• addBlocks: Mark tasks that cannot start until this one completes
• addBlockedBy: Mark tasks that must complete before this one can start

Status Workflow

Status progresses: pending → in_progress → completed

Use deleted to permanently remove a task.

Staleness

Make sure to read a task's latest state using TaskGet before updating it.

Examples

Mark task as in progress when starting work:

{"taskId": "1", "status": "in_progress"}

Mark task as completed after finishing work:

{"taskId": "1", "status": "completed"}

Delete a task:

{"taskId": "1", "status": "deleted"}

Claim a task by setting owner:

{"taskId": "1", "owner": "my-name"}

Set up task dependencies:

{"taskId": "2", "addBlockedBy": ["1"]}
