That architecture can coordinate multi-step work, but it can also repeat expensive calls, trust hostile context, misuse valid tools, or report success before the underlying business state is complete. Production design therefore begins with a bounded job and an authority model. Define the terminal states, allowed tools, identity, data scope, step and spend limits, approval transitions, and recovery owner before optimizing prompts. The model may interpret context and propose a path; deterministic services should still enforce permissions, schemas, destinations, transaction rules, and consequential approvals.

More autonomy magnifies the cost of unclear identity and missing stop conditions.
