Spending limits that survive autonomous loops
Design per-transaction, daily, and count limits that protect finance when agents iterate tool calls at machine speed—enforce limits with Auctra. Use Auctra.

Why loops break naive caps
An agent in a retry loop can attempt dozens of purchases in minutes if only per-transaction limits exist. Daily aggregates and count limits catch runaway automation quickly.
Auctra evaluates all active constraints on every evaluateAction call. Blocked attempts appear in audit with exceeded limit details for tuning.
Calibrating limits
Start from historical human approval thresholds minus a safety margin. Review Team accountability reports after two weeks to see actual utilization percentiles.
Tighten limits when error rates rise; loosen when approval queues grow on legitimate volume. Sponsors should own limit changes with documented rationale.
Multi-currency and vendor constraints
Express limits per currency to avoid conversion ambiguities. Vendor allowlists prevent agents from paying unapproved suppliers even within amount caps.
Agentic commerce compliance often requires both—document them in delegation templates. Export audit samples when onboarding new marketplaces.
Emergency brakes
Revoke delegations immediately during suspected compromise. Pair with payment processor velocity rules as defense in depth.
Auctra ties sponsors, expiring delegations, and pre-action evaluation into one accountability chain your security and finance teams can audit.
Key takeaways
- Authority is enforced before side effects — use Delegations and evaluateAction together.
- Every production agent needs a named sponsor and bounded delegation visible in the console.
- Blocked and approval-required outcomes are evidence, not failures — review them in Delegations.
Implementation checklist
- Sign up at console.auctra.tech and open Delegations (/console/delegations).
- Register one agent with a named human sponsor accountable for its actions.
- Create a narrow delegation aligned with this article's workflow (Spending limits that survive autonomous loops).
- Call evaluateAction from your agent or SDK before the consequential tool executes.
- Confirm sponsor, delegator, decision, and outcome appear in Audit or Delegations.
