Yup, I actually force my agents to build a formally validated CUE spec for everything they build, I have a service that gives them a wizard for interacting with the cue to add/remove/update, then when everything we discuss is represented they can use it to sync a project, which will automatically generate missing unit/e2e tests, iac docs, folder stubs with README.md files, etc. It was a lot of work to get agents to interact with the service correctly, so many facepalm moments, but it's pretty magical when it works.
