Mason: A declarative build tool on top of Dagger

Nice addition on top of Dagger — sounds conceptually similar to the now-defunct Earthly. Just one comment: please, no YAML. Anything but YAML/JSON — PKL, Starlark, TypeScript, you name it.

For the love of god, just use Nix. Oh look, more YAML. I really just can't, the more I look the more I'm in slight disbelief.
