Review failed Nx Cloud CI pipeline executions and group recurring, evidence-based failure patterns. Use this skill whenever a user asks about failed CI pipelines, recurring task failures, failed CIPEs, a CI failure review, or a last-24-hours CI report. Use the nx-cloud-api skill for every Nx Cloud read. This read-only skill separates task, workflow, agent, timeout, cancellation, and unknown cases. It suggests diagnostic next steps without changing systems.
