Protocol Buffers and gRPC service definition with backward compatibility checks

Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Protocol Buffers and gRPC Designer Skill ## Overview This skill specializes in designing Protocol Buffers schemas and gRPC service definitions with a focus on backward compatibility, performance, and cross-language interoperability. ## Capabilities - Design .proto files following Google's style guide and best practices - Implement gRPC service definitions with streaming support - Validate wire format backward compatibility - Generate language-specific stubs for multiple targets - Configure proto linting and breaking change detection - Design efficient message structures for performance - Implement gRPC interceptors and middleware patterns ## Target Processes - API Design Specification - Backward Compatibility Management - Multi-Language SDK Strategy ## Integration Points - buf (schema registry, linting, breaking change detection) - protoc (Protocol Buffer compiler) - grpcurl (gRPC testing) - gRPC-Gateway (REST transcoding) - Connect (modern gRPC alternative) ## Input Requirements - Service domain requirements - Message structure definitions - Streaming requirements (unary, server, client, bidirectional) - Target languages for code generation - Backward compatibility policy ## Out

What does the protobuf-grpc-designer skill do?
Protocol Buffers and gRPC service definition with backward compatibility checks
How do I install it?
Run `npx skills add a5c-ai/babysitter --skill protobuf-grpc-designer --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From a5c-ai/babysitter, a repository with 1,642 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
