I don't believe you can add custom analyzers to `go vet`, which arguably rules it out.

But it is extremely simple to make a custom vet-like tool, because it's a trivial binary wrapper around the analysis framework, which is first-party (though it's structurally pretty limited by design, and won't handle all linting needs): https://cs.opensource.google/go/go/+/refs/tags/go1.26.5:src/...
