ci-troubleshooting

Systematically debug GitHub Actions failures using a structured Observe → Cluster → Reproduce → Fix → Validate workflow. This approach identifies the actual root cause by observing logs within 30 seconds, clustering related failures, reproducing locally within 2 minutes, implementing a fix, then validating across local, branch CI, and main environments with prescribed commands.

Yes. This workflow guides you to identify the triggering commit by clustering multiple failures to a single root cause, then validating the fix across branch CI and main. This eliminates debugging each test individually and pinpoints the exact commit causing the pipeline break.

Use a non-hypothesis-driven workflow with fixed time budgets: 30 seconds to observe logs, 30 seconds to cluster failures, 2 minutes to reproduce locally. This systematic approach moves directly from observation to root cause identification, then validation through local, branch CI, and main tier environments.

No. This workflow identifies when multiple test failures share a single root cause through failure clustering, so you fix the underlying issue once rather than addressing each test separately. Multi-tier validation ensures the fix works before merging to main.

Validate fixes through a three-tier process: reproduce and fix locally, verify the fix passes on your branch CI pipeline, then confirm it passes on main. Prescribed commands for each tier ensure the root cause is actually resolved before integration.

This workflow applies to build, test, dependency, timeout, and infrastructure failures in GitHub Actions. The observation and clustering steps identify the root cause across these failure categories, enabling targeted fixes rather than guessing at solutions.
