WHY IT NEEDS A POLICY

Why add_case_comment needs a policy

This tool adds data to a case, which is a reversible write operation. It does not delete, execute arbitrary commands, or move money. The mutation semantic confirms it modifies case state. Severity is medium because adding comments to cases could inject misleading information into incident response workflows, potentially affecting decision-making, but the impact is bounded to case metadata and is reversible.

From the tool's definition Tool name 'add_case_comment' and description explicitly identifies it as a 'mutation addCaseComment' which creates/appends data (a comment) to an existing case record.
