WHAT IT DOES

What karea_close_task does on Karea

AI agents use karea_close_task to create or update resources in Karea — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Karea environment.

WHY IT NEEDS A POLICY

Why karea_close_task needs a policy

Closing a task changes its status irreversibly in the task management system. While the action itself is reversible (tasks can typically be reopened), it modifies application state and affects workflow. This is a Write operation rather than Destructive because the underlying task data persists and the action is not permanently destructive.

From the tool's definition Tool name 'karea_close_task' and description 'Mark a task as done' indicate a state change operation that modifies task data.
