What is the problem?
整理新手排查 GitHub Actions build 失败时的常见错误：只看最后一行、改错 workflow、删除测试、泄露 secret、忽略客户权限，并给出更稳的解决顺序。
Quick solution
Treat this as a GitHub troubleshooting issue. First confirm the environment, inputs, permissions, logs, and delivery boundary. Then use the linked deep guide for the full checklist before changing production code or promising a result.
Read the deep guideDetailed steps
- Confirm the scenario, tool version, account permissions, inputs, and expected output before changing anything.
- Check configuration, logs, command output, and human review boundaries against the linked deep guide.
- Record the before and after result, then verify that the fix did not introduce platform, privacy, or delivery risk.
Commands or code
The source article does not include a copyable command block. Do not invent commands here; follow the diagnostic steps in the deep guide and validate changes in the real project environment.
Risk notes
Confirm the real project environment, account permissions, platform rules, and output quality before delivery. Do not ship AI-generated changes without human review, and do not claim indexing, income, deployment success, or ranking improvements without measured evidence.
