What bb_add_pull_request_comment does on Bitbucket Cloud MCP Server

WHY IT NEEDS A POLICY

Why bb_add_pull_request_comment needs a policy

Adding comments creates reversible new data in the pull request system. While it modifies state, it does not execute code, delete data, move money, or trigger destructive operations. The blast radius is medium because malicious comments could spread misinformation or spam across pull requests, but the effect is containable and reversible. This is clearly a Write-category tool.

From the tool's definition Tool description states it 'Add a comment to a pull request' and supports threaded replies via parent_id. These are write operations that create new content (comments) in the repository collaboration system.
