WHY IT NEEDS A POLICY

Why create_task_document needs a policy

Attaching a file to a task is a reversible write operation that modifies task metadata/structure. It does not delete data (ruling out Destructive), execute arbitrary code (ruling out Execute), move money (ruling out Financial), or merely read data (ruling out Read).

From the tool's definition Tool description states 'Attach a file to a task' — this creates a new association/relationship between a file and a task, modifying task state by adding a document attachment.
