## TL;DR
The agent waited forever because nobody told it how long to wait. Set a client timeout shorter than the agent's step budget, retry a bounded number of times with backoff, and decide up front whether a timeout escalates to a human or holds the transaction.

```text
fraud agent timed out waiting for risk-score api response
```

## Use this when
- The agent hangs or crashes waiting on a slow score response.
- Review SLAs slip because one slow call blocks the queue.
- Timeouts cluster during provider incidents or traffic spikes.

## Not for this skill when
- The API returns 429. That is rate limiting, a different fix.
- Authentication fails. That fails fast already.
- Scores are slow but always return. That is a latency budget question.

## Steps
1. Set an explicit timeout on the risk-score client, shorter than the agent step timeout. Verify: a hung API call fails fast instead of hanging the run.
2. Wrap the call in bounded retries, two or three attempts with jittered backoff. Verify: a transient blip recovers without agent intervention.
3. Define the timeout policy with your risk team: fail-closed and hold the transaction, or fail-open with human review. Verify: the policy is written down, not improvised per incident.
4. Add a circuit breaker that pauses score calls after N consecutive timeouts and alerts. Verify: a degraded API does not take the whole queue down with it.
5. Log timeout rate per endpoint. Verify: you can distinguish a slow endpoint from a slow network.

## Variant phrasings
### risk score api timeout fraud agent
Same failure, common phrasing.
### agent hung on score api
Symptom-level search.
### score api slow response handling
Engineering-side wording.

Compatibility: Any risk-score API behind an agent tool call. Timeout and retry live in the agent's HTTP client.

## Why it happens
Score APIs degrade under load, and agents without timeouts inherit the worst case: a 90-second server stall becomes a 90-second frozen agent, then a cascade of missed SLAs. Timeouts convert an unbounded hang into a bounded, countable failure the agent can reason about and route around.

## Edge cases / pitfalls
- Fail-open without human review is a fraud hole. Fail-closed without alerting is a revenue hole. Pick one and instrument it.
- Retries on non-idempotent endpoints can double-apply side effects. Confirm the score call is safe to retry.
- Do not set the timeout so tight that normal p99 latency trips it. Measure first.
- A circuit breaker that never resets is just an off switch. Give it a half-open probe.
