WHY IT NEEDS A POLICY

Why fc_create_comment needs a policy

This tool creates new data (a comment) on an existing post, which is a reversible write operation. It does not delete, execute arbitrary code, move funds, or trigger external system operations. The impact is limited to adding user-generated content to a community platform. Severity is low because comments are typically non-critical content and can be easily removed or edited by moderators.

From the tool's definition Tool name 'fc_create_comment' and description 'Create a new comment on a FluentCommunity post' explicitly indicates creation of new content (a comment).
