Public Grpc API Design

Category: Engineering  ·  Sub-category: backend  ·  Last updated:
Design a public gRPC surface for external developers - the when-gRPC-at-all gate (most platforms keep gRPC internal and publish REST or transcoded JSON), AIP proto package and versioning conventions, buf breaking-change gates and their google.api.http blind spot, unary-by-default streaming decisions, the google.rpc.Status error model with its HTTP-mapping traps, transcoding and gateway architecture (Connect-RPC, grpc-gateway, Envoy), and external auth and TLS. Use whenever the user mentions gRPC, protobuf or .proto files, buf, Connect-RPC, grpc-gateway, or gRPC-JSON transcoding at a public edge - even if they never say "gRPC API design". Design layer only, not language-specific server implementation.

From the source SKILL.md

You are a public gRPC surface designer. Decide whether gRPC belongs at a platform's public edge at all, and - when it does - design the proto governance, streaming posture, error model, transcoding architecture, and external auth that let developers you have never met consume it safely.

What this skill does

Public Grpc API Design is a community-contributed Claude Code skill in the backend sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/public-grpc-api-design/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use whenever the user mentions gRPC, protobuf or .proto files, buf, Connect-RPC, grpc-gateway, or gRPC-JSON transcoding at a public edge - even if they never say "gRPC API design".

Who uses this skill

The Public Grpc API Design Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 196,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

Design layer only, not language-specific server implementation.
Is this skill free to install?
Yes. ClaudSkills is an open registry — every skill keeps its source repository's license, and manual install via copy is free. ClaudSkills Pro ($9/mo, $79/yr, or $149 one-time) adds one-click install via the desktop app and a multi-signal Quality Score.
When should I use the Public Grpc API Design skill?
Use Public Grpc API Design when your Claude Code task falls under the Engineering category — specifically in the backend area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Public Grpc API Design" or describe the task and let Claude pick). Browse related skills at /category/engineering/.
What is a Claude Code skill and how does the Public Grpc API Design skill fit in?
A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Public Grpc API Design is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Engineering category.
