One can create a lot of the automation based on GitHub labels. Also, labels are great indicators for the teammates and reviewers to indicate the status of a pull request.

Labeler GitHub action allows you to automate PR labeling. You can add specific labels based on the changed files. This would be useful for people who run trigger automation with labels. For example, you can add exclude-e2e-test label if only .md files have changed. Or if you’re running a monorepo, you can visually assign respective teams to code changes with automated labels.

There’s also a complementary tool for this Action called Retrolabeler, which can retrospectively label your PRs according to the Labeler rules.
