Very quickly mise went from "what's that?" to "I need it everywhere" because of the "overlay on existing systems" approach. It's all over our org at work, and all over the local dev community here. It has also simplified all of our CI and made the random python projects a breeze to run. Great work!

Ironically I pushed for it because it also has tasks that can be written in Bash (we have a mix of Bash scripts and Makefiles for task running across projects while I will die on the hill that shell scripts should be written in a shell script: not Makefile, not a string in a json file, not a string in a yaml file) but we never did get around to that.

it was definitely a risky move, env vars are not perfect for this use-case (varargs is awkward) but I'm happy I went with the file tasks setup and the magic comments anyways. It's nice that you're not working in bash-inside-yaml or coming up with a new file type. It is just bash.
