WHY IT NEEDS A POLICY

Why launchnotes_publish_announcement needs a policy

Publishing an announcement creates a visible, public change (subscribers receive notification) but is not destructive—the announcement can be archived or unpublished later. It is not Execute (no arbitrary code execution), not Destructive (reversible), and not Financial (no money moves). While it affects visibility, the core operation is a state change/modification typical of Write operations.

From the tool's definition Tool description states 'Publish an announcement immediately, making it live and visible to subscribers' — this modifies the state of an announcement from draft/unpublished to published, a reversible operation.
