When using GitHub Actions, we often
include steps that use Git to check out the code of the repository, make some
changes to the code, and then commit these changes back to the repo. Additional
steps subsequently act upon these changes within the same workflow run. For
example, appending auto-generated release notes to a CHANGELOG.md file and
committing it to the repo, to later bundle the changelog with release artifacts.
Another example is using a workflow that periodically uses a linter to clean up
the code base. Simple enough, right?
