WHY IT NEEDS A POLICY

Why neptime_create_article_comment needs a policy

This tool creates a new comment on an article, which is a reversible write operation. The data can be modified or deleted (as evidenced by the sibling tool 'neptime_delete_comment'), so it does not qualify as Destructive. It has no financial impact and does not execute arbitrary code. Rate limiting (50 comments/day, 10s between posts) mitigates abuse potential, keeping severity low.

From the tool's definition Tool name includes 'create' and description states 'Post a comment on an article', which creates new data (a comment) reversibly.
