WHY IT NEEDS A POLICY

Why update_ticket needs a policy

This tool modifies ticket state (status, priority) and adds comments, which are typical Write operations. The changes are reversible (status and priority can be changed again, comments can be removed or edited). While ticket updates in ITSM systems can have business impact, they do not constitute Financial operations, are not Destructive (no deletion), and do not Execute arbitrary code.

From the tool's definition Tool description states it can 'Update the status, priority, or add a comment to an existing ticket' — these are reversible modifications to ticket data.
