WHY IT NEEDS A POLICY

Why mark_thread_addressed needs a policy

This tool creates or modifies data reversibly: it changes the status of a feedback thread to 'resolved' and optionally appends a message. These actions are reversible (a thread can be reopened or a message deleted), making it a Write operation rather than Destructive.

From the tool's definition Tool description states it 'Mark[s] a feedback thread as resolved' and can 'Optionally add a message', which modifies the state of a feedback thread and potentially adds data to it.
