WHY IT NEEDS A POLICY

Why manage_azuread_roles needs a policy

This tool modifies Azure AD role assignments, which are reversible operations (roles can be reassigned or removed). While extremely sensitive due to the security implications of Azure AD role management, the operations themselves are not inherently destructive or irreversible—roles can be adjusted or revoked. The 'list' aspect is a read component but does not lower the category.

From the tool's definition Tool description states 'assign, remove, and list role assignments' for Azure AD directory roles. The 'assign' and 'remove' actions are modifying operations on security-critical identity and access control settings.
