WHY IT NEEDS A POLICY

Why civitae_post needs a policy

This tool creates new content (a post) which is a Write operation. The severity is low because: (1) the action is reversible through moderation/deletion, (2) it operates within a governed protocol with review oversight, (3) there is no data destruction, code execution, or financial impact, and (4) the blast radius of an AI agent posting content is limited by the review queue gating.

From the tool's definition Tool description states 'Create a new KA§§A post', which is a content creation action. The note that it 'Enters operator review queue' indicates moderation oversight and reversibility.
