Idempotency in agent action evaluation
Prevent duplicate charges and duplicate audit noise when agents retry tool calls after timeouts or approvals—idempotency patterns for Auctra evaluateAction.

Why agents retry
LLM orchestration retries on transient errors, network blips, and user impatience. Without idempotency, retries can double-evaluate or double-execute monetary actions.
Pass a stable idempotencyKey per logical business action as the second evaluateAction option. Auctra returns the original decision when that key is reused for the same request.
Key design
Derive keys from business identifiers: orderId + actionType, or a client-generated UUID stored at intent creation. Do not reuse keys across different actions or amounts.
After approval, reuse the same key when resuming execution. Downstream payment APIs should use their own idempotency headers aligned to the same logical action.
Failure scenarios
If evaluateAction succeeds but downstream fails, retain action_request_id for correlation and use the downstream API's own idempotency control. If evaluation inputs change materially, generate a new Auctra idempotencyKey.
Document retry policy in agent runbooks for on-call engineers. Team audit helps debug idempotency collisions during integration.
Testing
Simulate duplicate evaluateAction calls in CI and assert identical action_request_id values. Include approval resume paths in idempotency tests.
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 API keys 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 API keys.
Implementation checklist
- Sign up at console.auctra.tech and open API keys (/console/api-keys).
- Register one agent with a named human sponsor accountable for its actions.
- Create a narrow delegation aligned with this article's workflow (Idempotency in agent action evaluation).
- Call evaluateAction from your agent or SDK before the consequential tool executes.
- Confirm sponsor, delegator, decision, and outcome appear in Audit or API keys.
People also ask
- What is idempotency in agent action evaluation?
- Supplying a stable key so retries return the same authority decision instead of creating duplicate evaluations or executions.
- How does Auctra handle idempotency keys?
- Duplicate evaluateAction requests with the same key return the original decision within the retention period.
- How does Auctra help with agent authority?
- Auctra registers sponsors, issues expiring delegations, evaluates actions before execution, and preserves auditable accountability records.
