Least-Privilege Tool Architecture
During review-only mail tasks, publish narrow read/search tools backed by an identity without mail mutation scope. Remove generic terminal access and ambient gog credentials that can bypass those tools. The guidance's typed database example needs a mail-provider adapter with independently tested read-only grants; a prompt or tool name saying read-only is insufficient. This prevents the delegated run from performing cleanup even if it loses the user's instruction.
