WHY IT NEEDS A POLICY

Why create_forum_post needs a policy

This tool creates new data (a forum post) in a Discord server, which is a reversible write operation. The severity is medium because while forum posts can be deleted, creating them could be misused to spam, create misleading content, or disrupt server discussions, but the impact is limited to a single Discord server and the action is reversible.

From the tool's definition Tool name 'create_forum_post' and description 'Create a new post in a forum channel' indicate creation of new content.
