## Behavior and boundaries

Permanently deletes exactly one writable Google Tasks or Microsoft To Do task. Use list_tasks or get_task first and proceed only when exactly one intended task matches and writable=true. The account, list, task, provider grant, organization binding, and current existence are revalidated immediately before deletion. Repeating the same deletion is safe and reports changed=false.

## Permissions

Granted scopes, accounts, calendars and visibility rules limit access. Workspace administrators do not automatically gain access to other users’ accounts.

`tasks:read`, `tasks:write`
