Cerberus schema based linting and code completion

[jmlord]

We have a Cerberus schema format that is used to validate .yml files in a GitHub action, using navikt/yaml-validator.

Now we would like to push this further and use the Cerberus schema to fuel a VS Code extension or RStudio add-in that would do linting and code completion. I was thinking of hooking the Cerberus schema on an existing language server or extension like Prettier, rather than designing a bespoke plugin.

Are there existing tooling to do that?

(This is not an issue per se, rather a question. This formerly was a Stack Overflow question, but it was closed as too library specific, so I brought it here.)
