WHY IT NEEDS A POLICY

Why update_jira_issue needs a policy

JIRA updates can modify issue state, assignments, status, priorities, and other metadata. These changes are reversible (distinguishing from Destructive), but have organizational impact—teams depend on accurate issue tracking. High severity reflects potential to corrupt project state or create confusion if an AI agent injected malicious updates.

From the tool's definition Tool name 'update_jira_issue' indicates modification of issue data. Description is empty, but name and context (issue tracking system with sibling tools for commenting and editing) establish this as a write operation that modifies existing JIRA issues.
