WHY IT NEEDS A POLICY

Why fc_create_post needs a policy

This tool creates new data (a post) in the FluentCommunity system, which is a Write operation. It does not delete, execute code, move money, or perform destructive actions. Severity is medium because while post creation is reversible (posts can be edited or deleted later), an AI agent could spam, create inappropriate content, or flood the community, causing operational disruption and requiring administrative cleanup.

From the tool's definition Tool named 'fc_create_post' with description 'Create a new post in FluentCommunity' explicitly performs content creation, a reversible write operation.
