WHAT IT DOES

What confluence_add_comment does on Atlassian

WHY IT NEEDS A POLICY

Why confluence_add_comment needs a policy

Adding a comment creates new content that is reversible (comments can be edited or deleted later). This is a Write operation—it modifies state by appending data but does not execute arbitrary code, delete content, or cause financial impact. Severity is medium because malicious comments could spread misinformation or disrupt collaboration, but the impact is limited to a single page's comments and can be remediated.

From the tool's definition Tool name 'confluence_add_comment' and description 'Adds a comment to a Confluence page' indicate creation of new comment data on an existing page.
