The note on how all those tools seem to mostly be spec-first and vague about spec maintenance was interesting to me. Me and my cofounder have been going all-in on spec-as-source, as we think it's really the most interesting use of specs, but it's also challenging to get of the ground. If anybody has any thoughts on this, I'd love to hear them.

Also in case somebody wants to try a spec-as-source tool, we'd love feedback: https://specific.dev
