Using jdx/mise in GitHub Actions has been very nice, I recommend it. It's not just a nice task runner, it also manages the dependencies of your tasks (stuff like Python, Node.js, even random tools from GitHub) so that "mise run build" does the exact same thing both locally and in CI. Then the ideal GHA workflow is just "install mise, run this mise task". And not only for building, we have it set up for commit checks too.
