I have re-developed this package into pacwich, which supports Bun, npm, or pnpm. I decided it would be a better direction for it to be decoupled from a particular package manager, so it needed a new name (but I wanted to keep my logo).
I write about the development strategy and my engineering philosophy (including disclosing the manner in which AI assists and my approach to not vibing this) in the Security page and the launch blog post about the pivot, which I linked on the home page in the note about the bun-workspaces migration.
More is to come, including a way to compose scripts into more complex workflows rather than running one named script in parallel/series.
