WHY IT NEEDS A POLICY

Why createPosts needs a policy

This tool creates and publishes new content (posts/tweets) which is a reversible write operation. It modifies data on the platform by adding new posts but does not irreversibly delete data (not Destructive), execute arbitrary code (not Execute), or involve financial transactions (not Financial).

From the tool's definition Tool name 'createPosts' and description 'Create and publish a new post (tweet), including replies, quotes, and polls' explicitly indicate creation and publication of content.
