Bound every GCS polling request.

curl has no transfer timeout at either site. A stalled GCS connection blocks the loop and prevents analysis until the outer step timeout terminates the post-step.

SYSTEM_PROMPT="IMPORTANT CI CONTEXT:
- You are running inside the CI job itself as a post-step.
- This step's artifact directory is: ${ARTIFACT_DIR}
- Other steps' artifacts (build-log, JUnit, install, gather) are available via GCS at: ${PROW_JOB_URL}
- You have network access to download artifacts from GCS using curl.
- Write the final analysis report to: ${ARTIFACT_DIR}/failure-analysis.md
- Use --fast mode (do NOT use AskUserQuestion).
- Do NOT prompt for JIRA export — just write the markdown analysis.

LIBVIRT CONTEXT:
- These jobs install OpenShift on IBM Z (s390x) or IBM Power (ppc64le) KVM guests via UPI libvirt.
- Workflows: openshift-e2e-libvirt-vpn, openshift-e2e-libvirt-vpn-fips, openshift-e2e-libvirt-upi, openshift-e2e-libvirt-upi-fips.
- Z uses cluster profile libvirt-s390x-vpn. Power uses libvirt-ppc64le-s2s.
- Install steps: upi-conf-libvirt, upi-install-libvirt. Test step: openshift-e2e-libvirt-test.
- ARCH is ${ARCH:-unknown}.
- Power (ppc64le) injects chrony to clock.corp.redhat.com. Z (s390x) RHCOS 10 KVM guests may have a broken PHC refclock; LPAR NTP is the libvirt gateway 192.168.<subnet>.1.
- Serial jobs (TEST_TYPE=conformance-serial) include oc adm upgrade recommend, which fails when NodeClockNotSynchronising fires.
- Prefer evidence from junit, install logs, node journals, and MachineConfigs over speculation."

Claude Code CLI --output-format stream-json --verbose stdout event contents tool results documentation

💡 Result:

When using the Claude Code CLI, the --output-format stream-json flag enables a machine-readable, newline-delimited JSON output stream, which is ideal for programmatic consumption [1][2]. When combined with --verbose and --include-partial-messages, the CLI emits detailed, real-time events as the agent processes the request [1][2]. Each line of the stream is a JSON object representing an event [1][2]. While formal documentation for every top-level event type is limited, the stream typically includes messages such as system, assistant, stream_event, and result [3]. The final line of the stream is always a result message containing the final response text, cost information, and session metadata [1][2]. For scenarios involving tool calls, the CLI emits tool_use and tool_result blocks [4][5]. If you need to include partial streaming events (such as text tokens being generated in real-time), you must use the --include-partial-messages flag [4][1]. You can filter these events using tools like jq to extract specific data, such as text_delta updates [1][3]. Key flags for this workflow include: --output-format stream-json: Sets the output to newline-delimited JSON [1][2]. --verbose: Enables detailed logging [6]. --include-partial-messages: Includes partial stream events (like text deltas) in the output [4][5]. --forward-subagent-text: If subagents are used, this flag allows you to emit subagent text and thinking blocks as assistant/user messages, enabling the reconstruction of subagent transcripts [4][5]. For advanced use cases or when building a streaming consumer, it is recommended to refer to the Agent SDK streaming output documentation, as it provides a more comprehensive reference for event types, message flows, and data schemas than the current CLI-specific documentation [3].

Stop streaming Claude output to CI logs.

--output-format stream-json includes tool events and results. tee copies these events to CI logs, where artifact-derived content can be exposed. Redirect stdout to the artifact file instead.

Reserve time after polling for report handling.

The script can poll for 600 seconds and then run timeout 1200 claude. Those limits already equal this 30-minute step timeout. The step can terminate before CLAUDE_EXIT handling and artifact writes when finished.json arrives late.

Increase the ref timeout or reduce the Claude timeout to leave a cleanup buffer.
