Checks provide automated evidence
Pull requests can display checks from GitHub Actions and other integrations. Checks may compile the project, run tests, lint code, scan dependencies or verify deployment requirements.
Passing checks are not the entire review
Automation catches repeatable problems, but reviewers still need to inspect design and behavior. A green build means the configured checks passed; it does not prove that every requirement is correct.
Required checks
Repositories can require selected checks before a protected branch accepts a pull request. This makes quality gates consistent instead of relying on memory.
