I decided to give it a try. It wants you to select your "proto path" as a first step. Mine is a directory; we have something like src/ and then subsystems' proto files live in src/subsystem/subsystem.proto and import each other with 'import subsystem/subsystem.proto'. It didn't let me pick a directory with the file checker, nor did it let me just type a directory name, so that's annoying.

I picked one of the subsystems at random and it fails to import gogo's proto files. Yeah, that's always an annoyance, I guess you have to "go mod download" and add the correct path under ~/go/pkg/mod/... to locate that for it.

I couldn't figure out how to let it connect to my server and just autodiscover the protos like grpcurl does. At this point I gave up. I usually just make a main.go somewhere that does cc := grpc.Dial(...); res, err := whatever.FooClient(cc).Method(&whatever.Request{...}); fmt.Println(res, err) when I want to test something, so I doubt I'd integrate this with my workflow anyway.
