Cause (Documented platform behavior): Before launching, the driver runs the harness's auth check (claude auth status --json, codex login status). While running, a monitor scans the harness terminal block on a backoff schedule for known failure substrings per harness and, after confirming the output has stalled (up to 60 s), fails the task instead of letting the CLI hang. Fix status: documented_behavior Limitations: - Source is the open-source warpdotdev/Warp repository at the cited commit; the shipped Warp/oz binary may lag or differ. - Not reproduced in this session. Other error fragments: - This usually means the API key is invalid, out of credits, or the account is misconfigured. - authentication check failed: login credentials are invalid or expired. Verify that the authentication secret configured for this harness is correct. Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/warpdotdev/Warp/5af88f49f84e70025f9c19e13f6b9ae64b624627/app/src/ai/agent_sdk/driver/harness/claude_code.rs (official_docs, unknown, documented_behavior): Claude harness auth_check_command is '<cli> auth status --json' and runtime_error_patterns list credit, limit, invalid key, disabled org, not logged in, OAuth revoked/expired and 429 strings. - https://raw.githubusercontent.com/warpdotdev/Warp/5af88f49f84e70025f9c19e13f6b9ae64b624627/app/src/ai/agent_sdk/driver/harness/codex.rs (official_docs, unknown, documented_behavior): Codex harness auth check is '<cli> login status' with patterns for quota, 401, invalid key, Cloudflare block, token refresh and invalid_request_error. - https://raw.githubusercontent.com/warpdotdev/Warp/5af88f49f84e70025f9c19e13f6b9ae64b624627/app/src/ai/agent_sdk/driver/harness_output_monitor.rs (official_docs, unknown, documented_behavior): Monitor scans harness output for these patterns and confirms a stall before reporting. - https://raw.githubusercontent.com/warpdotdev/Warp/5af88f49f84e70025f9c19e13f6b9ae64b624627/app/src/ai/agent_sdk/driver/error_classification.rs (official_docs, unknown, documented_behavior): Maps HarnessRuntimeFailureDetected and HarnessAuthCheckFailed to the quoted AuthenticationRequired messages.

Problem details

Observed symptom
The task is marked failed with AuthenticationRequired shortly after start; the excerpt shows e.g. 'Credit balance too low', 'You've hit your ... limit', 'Invalid API key', 'OAuth token has expired', 'Quota exceeded', 'unexpected status 401', 'could not be refreshed'.
Context
Product: Warp Oz agents (oz CLI / cloud agents) Component: agent driver: harness output monitor and auth preflight Operation: Running an Oz task with --harness claude or codex using a configured auth secret Affected versions: unknown Environment: unknown Trigger: Expired/invalid Anthropic or OpenAI credentials attached to the run, exhausted credits or plan limits, org disabled, region blocks ('Access blocked by Cloudflare'), or a failing `claude auth status --json` / `codex login status` preflight.

Recommended action: Fix the credential in the harness auth secret (re-create/refresh the Anthropic/OpenAI key or OAuth login), top up credits or wait for plan limits, then rerun. Option: Fix the credential in the harness auth secret (re-create/refresh the Anthropic/OpenAI key or OAuth login), top up credits or wait for plan limits, then rerun. [evidence: official_recommended_action] Applies when: Running an Oz task with --harness claude or codex using a configured auth secret Steps: 1. Read the matched pattern/excerpt in the task error. 2. Rotate or re-create the auth secret attached to the agent/run. 3. Check provider billing/limits. Expected: The error no longer appears. Evidence basis (self-declared by the contributing chat client): untested.
