Finding: wb01-tools-c159c6aae0cbe3a7de — Know and set SDK retry and timeout defaults when running tool agents Classification: ENVIRONMENT_TRAP Claim: The OpenAI Node SDK README states that connection errors, 408, 409, 429 and 5xx responses are retried 2 times by default with short exponential backoff, and requests time out after 10 minutes by default, with timed-out requests also retried twice. Scope: tools; version OpenAI SDK git snapshot; task family API error, retry and timeout configuration Rationale (SOURCE_REPORTED): INFERENCE: automatic retries and a long default timeout can lengthen wall-clock time; the source gives no latency figures. INFERENCE: retries re-send API requests rather than re-execute application tools; the excerpt does not state this. Evidence strength: LIMITED Transferability: LOW Cost effect: UNKNOWN; latency effect: UNKNOWN Recommended behavior: INFERENCE: under step or time budgets set maxRetries and timeout explicitly and log the request ID. Anti-pattern: Assuming the SDK fails fast or ignoring hidden retries in time budgets. Material claims and sources: - claim-1: The OpenAI Node SDK README states that connection errors, 408, 409, 429 and 5xx responses are retried 2 times by default with short exponential backoff, and requests time out after 10 minutes by default, with timed-out requests also retried twice. [openai-errors; EXTERNAL_EVIDENCE] Applicability: - Agent harnesses using the OpenAI Node SDK at this snapshot - Runs with wall-clock or step budgets Failure modes: - Hidden retries consuming time or rate-limit budget - Long waits before a timeout surfaces Limitations: - Defaults may change across versions - Worst-case latency not stated in source - Node SDK only Unknowns: - Retry frequency in practice - Effect on task success, cost or latency Counterevidence: - Not observed in this review. Sources: - openai-errors: https://github.com/openai/openai-node/blob/bc6c0bfb70f253d5caa3f335699e9713ea9067b5/README.md (OFFICIAL_REPOSITORY; retrieved 2026-10-08T22:34:16.158Z) This is an original source-grounded research note, not an official benchmark endorsement or a measured benchmark improvement.
