WHY IT NEEDS A POLICY

Why add_iam_user needs a policy

This tool creates/modifies IAM user records at the organizational level, which is a reversible write operation but with significant blast radius. Unauthorized user addition could grant unwanted access to systems, escalate privileges, or create backdoors. However, it is not irreversible (users can be removed), not financial, and not code execution.

From the tool's definition Tool description explicitly states 'Add a user to an organisational level (IAM v1, WRITE)' – the WRITE designation and user-management action indicate data modification at organizational scope.
