This is a comprehensive reference for working with Protocol Buffers and the buf toolchain. It enforces a strict workflow: match existing project style, write proto code with mandatory protovalidate constraints on every field, then verify with buf format and lint. The skill includes templates for common service patterns (CRUD with pagination, batch operations), language-specific buf.gen.yaml configs for Go, TypeScript, Python, and Java, and practical guidance on schema evolution and breaking changes. The insistence on validation for production APIs is opinionated but sensible. If you're building gRPC or Connect services and want to avoid the usual proto pitfalls around versioning and validation, the troubleshooting guide and review checklist alone make this worth having.
