Building a gRPC Lattice integration

Use this skill when the protocol choice is gRPC. Keep the guidance language-agnostic: prefer the user's existing language and tooling, generate the stubs you need, and only go deep on language specifics when the build actually requires it.

When to choose gRPC

Prefer gRPC when the user has:

• an existing protobuf or .proto contract,
• streaming or higher-rate telemetry requirements,
• a generated-stub workflow already in place,
• or a hardware or bridge integration that is naturally proto-first.

If the user also needs the Objects API, call out explicitly that Objects is REST-only and either add a small REST companion or reconsider the protocol choice.
