buf-regen

Regenerate Go code from protobuf definitions.

When to use

After any change to files in proto/specgraph/v1/*.proto.

Steps

  1. Run buf lint to validate proto files
  2. Run buf generate to regenerate Go code in gen/
  3. Run go mod tidy to update dependencies
  4. Run go build ./gen/... to verify generated code compiles
  5. Report any errors

Notes

  • Generated files go to gen/specgraph/v1/ (protobuf) and gen/specgraph/v1/specgraphv1connect/ (ConnectRPC)
  • Never hand-edit files in gen/ — they are overwritten by buf generate
  • buf STANDARD lint requires unique response type names per RPC (wrap with GetXxxResponse, UpdateXxxResponse)
