Vim-flow: declarative dev/build/test cycles in vim

I'm the author of this plugin, I'd love to hear what you all think.

For some background, I've been using this sort of work flow within vim for about a year now and finally decided to make the project more robust and easier to use. I find it helpful to be able to declaratively tell vim how I want to execute and validate my current working project.

Would love to hear suggestions and ways to make this better!
