Your AI agent shouldn't have more permissions than the employee it assists

The author warns against granting agents broad API access for convenience: a sales assistant agent can then modify records it shouldn't, access unrelated customer data, and act outside its role — an old security problem surfacing through a new vector.
Recommended practices: least-privilege permissions, scoped credentials, tool input validation, explicit approval for sensitive actions, and treating retrieved documents and user messages as untrusted input rather than permission-overriding instructions. Key line: an agent making a bad decision is one problem; having the authority to turn it into a serious incident is another.
