WHY IT NEEDS A POLICY

Why add_jira_comment needs a policy

Adding a comment creates new data within a Jira issue and is reversible (comments can typically be edited or deleted). This is a Write operation rather than Read (retrieves data) or Execute (runs arbitrary code).

From the tool's definition Tool description states it 'Adds a comment to an existing Jira issue' — this is a create operation that modifies an issue by adding new content. The mention of controlling 'visibility of the comment' indicates additional write-level control over data state.
