Protocol Buffers Design Skill

When to Use This Skill

Use this skill when:

• Designing gRPC services - Protocol Buffers (proto3) for typed service contracts
• Schema definition - Messages, enums, services, streaming patterns
• Implementing in C# - gRPC with ASP.NET Core
• Schema evolution - Backward/forward compatibility, versioning

MANDATORY: Documentation-First Approach

Before creating protobuf definitions:

1. Invoke docs-management skill for API contract patterns
2. Verify proto3 syntax via MCP servers (context7 for latest spec)
3. Base all guidance on Google's Protocol Buffers documentation
