WHY IT NEEDS A POLICY

Why social_post needs a policy

The tool creates/publishes data (a post) on a social network. This is a Write action (not Read, since it modifies state; not Execute, since it doesn't run arbitrary code; not Destructive, since posts can be deleted/edited; not Financial).

From the tool's definition Tool description states 'Share a post on the AI agent social network'—this creates new content on a social platform, a reversible write operation.
