What it does

Generating Grpc Services is an agent skill from jeremylongshore/tons-of-skills-marketplace. Generate gRPC service definitions, stubs, and implementations from Protocol Buffers. Use when creating high-performance gRPC services. Trigger with phrases like "generate gRPC service", "create gRPC API", or "build gRPC server".

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/errors.md`, `references/examples.md` and `references/implementation.md`). Compatibility notes: Designed for Claude Code

It sits in Backend & APIs, covering gRPC and Protobuf. It works with gRPC. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Write
    • Edit
    • Grep
    • Glob
    • Bash(api:grpc-*)

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • grpc.io
    • protobuf.dev
    • buf.build
    • grpc-ecosystem.github.io

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Designed for Claude Code

    From compatibility in the SKILL.md frontmatter.

Context cost

Generating Grpc Services loads about 1.3k tokens when it runs, and up to ~3.8k if it reads all its reference files. Until then it costs about 63 tokens; SKILL.md has 514 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~63
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.8k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Generating gRPC Services

Overview

Generate gRPC service definitions, client/server stubs, and implementations from Protocol Buffer (protobuf) .proto files. Scaffold unary, server-streaming, client-streaming, and bidirectional-streaming RPC methods with proper error status codes, interceptors for auth/logging, and health check service registration.

Prerequisites

  • Protocol Buffers compiler (protoc) v3.21+ installed
  • Language-specific gRPC plugin: grpc_tools_node_protoc_plugin (Node.js), grpcio-tools (Python), or Go gRPC plugin
  • buf CLI for proto linting and breaking change detection (recommended)
  • gRPC testing tool: grpcurl, evans, or BloomRPC
  • TLS certificates for production transport security (mTLS recommended for service-to-service)

Instructions

  1. Read existing .proto files using Glob and Read, or design new service definitions with message types, RPC methods, and streaming patterns per service requirements.
  2. Define proto3 message types with appropriate field types, using google.protobuf.Timestamp for dates, google.protobuf.Struct for dynamic fields, and oneof for polymorphic messages.
  3. Compile .proto files with protoc to generate language-specific stubs, server interfaces, and client libraries using the appropriate gRPC plugin.
  4. Implement server-side RPC handlers for each method, returning proper gRPC status codes (OK, NOT_FOUND, INVALID_ARGUMENT, PERMISSION_DENIED) instead of generic errors.
  5. Add server interceptors for authentication (extracting JWT from metadata), request logging with correlation IDs, and deadline propagation across service calls.
  6. Implement health check service (grpc.health.v1.Health) and reflection service for runtime introspection by tools like grpcurl.
  7. Configure TLS transport security, preferring mutual TLS (mTLS) for service-to-service communication with certificate rotation support.
  8. Write integration tests using an in-process test server, validating all RPC methods including streaming scenarios with multiple messages and error conditions.
  9. Generate a REST-to-gRPC gateway using grpc-gateway annotations for HTTP/JSON clients that need to access gRPC services.

See ${CLAUDE_SKILL_DIR}/references/implementation.md for the full implementation guide.

Error Handling

ErrorCauseSolution
INVALID_ARGUMENT (3)Request message fails field validation constraintsReturn detailed BadRequest error details with field-level violation descriptions
NOT_FOUND (5)Requested resource does not existInclude resource type and ID in error message metadata for client debugging
PERMISSION_DENIED (7)Caller lacks required role or scope in JWT metadataReturn required permission in error details; log denied access attempt
DEADLINE_EXCEEDED (4)RPC took longer than client-specified deadlinePropagate deadlines to downstream calls; implement cascading timeout budgets
UNAVAILABLE (14)Server overloaded or downstream dependency unreachableClient should retry with exponential backoff; server should implement backpressure

Refer to ${CLAUDE_SKILL_DIR}/references/errors.md for comprehensive error patterns.

Examples

User management service: Define UserService with CreateUser, GetUser, ListUsers (server-streaming for large result sets), and UpdateUser RPCs with field mask support for partial updates.

Real-time event stream: Bidirectional streaming RPC where clients subscribe to event topics and the server pushes filtered events, with flow control via client-side backpressure signals.

gRPC-Web frontend: Generate gRPC-Web compatible stubs for browser clients using Envoy proxy for HTTP/2 to gRPC translation, enabling direct proto-based communication from React/Vue applications.

See ${CLAUDE_SKILL_DIR}/references/examples.md for additional examples.
