Task Assignment

How to assign team members to tasks and filter your board by assignee.

Who can be assigned?

Any organisation member who has Edit permission or higher on a board can be assigned to tasks on that board. This includes:

• Owners and admins (who have automatic full access to all boards)
• Members with a direct, team, or organisation-wide grant of Edit, Share (team), or Share (org)

If someone only has Read access to a board, they will not appear in the assignee picker.

See Organisations and Teams for details on permissions and sharing.

Assigning users to a task

1. Open a task by clicking it on the board
2. Scroll to the Assignees section (below Priority)
3. Click + Add assignee to open the picker
4. Search for a member by name or email (optional)
5. Click a member to assign them — a checkmark appears next to their name
6. Click away from the picker to close it

You can assign multiple people to the same task. Each assigned member appears as a chip showing their avatar and name.

Self-assignment

You can assign yourself to any task on a board where you have edit access. There is no distinction between assigning yourself and assigning someone else.

Removing an assignee

On the task detail page, each assignee chip has a small × button. Click it to remove that person from the task. Only users with edit permission on the board can add or remove assignees.

Assignee avatars on the board

When a task has assignees, their profile pictures (or initials if no picture is set) appear as small overlapping circles on the task card in the board view. Up to three avatars are shown; if there are more, a +N indicator appears.

This gives you a quick visual overview of who is working on what without opening each task.

Filtering by assignee

When at least one task on the board has an assignee, a Filter by assignee dropdown appears above the board lanes. Use it to focus on specific work:

To clear the filter, select All from the dropdown or click the × button next to it.

The filter works on all lanes simultaneously — cards that do not match the filter are hidden.

What happens when someone loses access?

If a member is removed from the organisation, removed from a team, or has their board grant revoked, their task assignments are automatically cleaned up:

• The system checks whether the person still has edit access through any other route (e.g. they lost a team grant but still have a direct grant)
• If they no longer have edit access, they are silently removed from all tasks on that board
• No manual cleanup is needed

This ensures that only people who can actually work on a board remain assigned to its tasks.

Assigning via the API and MCP

If you use the External API or MCP tools, you can include assignee user IDs when creating or updating tasks:

• Create task: pass assigneeIds — an array of user ID strings
• Update task: pass assigneeIds to replace the current assignee list

See the External API documentation and MCP tool descriptions for details.
