WHY IT NEEDS A POLICY

Why create_social_post needs a policy

This tool creates or modifies social media content, which is a reversible write operation. It does not execute arbitrary code, delete data, or move money. However, severity is medium rather than low because autonomous posting to social media by an AI agent without proper authorization could have reputational or compliance consequences, and the tool's broad scope ('any topic') increases misuse potential.

From the tool's definition Tool name 'create_social_post' and description 'Generate a social media post with image and text for any topic' indicate creation of content.
