Loop engineering: approval gates

Human-in-the-Loop Design Regulators Actually Accept

Full autonomy is rarely the right answer in enterprise, especially in banks. The design skill is deciding exactly where a human must approve, and making that approval fast enough that ops teams do not bypass it.

The problem in prod

  • Agents that draft compliance reports, move money logic, or touch customer records cannot fail silently.
  • Review queues designed by engineers get skipped by operators under time pressure.
  • Regulators ask who approved what, and clickwrap logs do not count as evidence.

Loop engineering

Quality compounds when every failure feeds a named loop with an owner and a metric.

Risk-tier loop

Classify every agent action: auto-approved (read-only summaries), one-click approve (drafts, flags), committee review (external effects). BBVA runs thousands of GPTs inside exactly this kind of tiered trust.

Reviewer feedback loop

Every override or edit by a reviewer becomes a labeled training and eval case. Override rate per action type is the metric that tells you when to widen or narrow autonomy.

Audit evidence loop

Each approval records who, what version, what evidence was shown, and the policy cited. Exportable per case for BNM or internal audit.

Production hardening checklist

  • Default deny on external actions. Agent proposes, human disposes.
  • Show the reviewer the exact retrieved sources, never just the draft.
  • Time-box approvals with escalation, so queues cannot stall operations.
  • Simulate reviewer absence: deputy routing and break-glass with full logging.
