I saw someone mention "pulumi config" and then slack scrolled away. not sure if it's related. is there a good pre-commit hook for ensuring the pulumi yaml files match what pulumi expects. pulumi preview+up always re-orders fields

Not aware of one. If it's of interest, I've seen a few GitHub issues that touch on this. I've only found one, I think there's more: https://github.com/pulumi/pulumi/issues/423
