golang-grpc

Provides gRPC usage guidelines, protobuf organization, and production-ready patterns for Golang microservices. Use when implementing, reviewing, or debugging gRPC servers/clients, writing proto files, setting up interceptors, handling gRPC errors with status codes, configuring TLS/mTLS, testing with bufconn, or working with streaming RPCs.

Quality

Content

87%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is a tight, actionable gRPC reference with real progressive disclosure into bundle files. Its only weakness is the absence of explicit validation/feedback loops, leaving workflow_clarity at 2.

Suggestions

Add an explicit validate→fix→retry checkpoint for the production setup steps (e.g. after configuring TLS/mTLS, run a connectivity/mTLS handshake check before declaring the server production-ready).

Turn the graceful-shutdown snippet into a short sequenced workflow with an explicit 'verify drain completes; otherwise force Stop()' validation step.

Add a brief verification step after proto generation (e.g. 'run `protoc`/`buf generate` then confirm generated files compile with `go build ./...`') to close the feedback loop on the code-gen step.

DimensionReasoningScore

Conciseness

Lean, table-and-bullet-driven body that assumes Claude's competence and avoids explaining basic concepts; explanatory clauses (e.g. 'a slow upstream hangs goroutines indefinitely') add value rather than padding.

3 / 3

Actionability

Multiple complete, executable Go code blocks (server setup, interceptors, client with retry policy, streaming, error handling) plus concrete commands and named packages — copy-paste ready.

3 / 3

Workflow Clarity

The body defines Build/Review modes and topic sections but is a best-practices reference rather than a sequenced workflow; it lacks explicit validate→fix→retry checkpoints for risky operations like production TLS or shutdown, which caps clarity at 2.

2 / 3

Progressive Disclosure

Clear overview with well-signaled, one-level-deep references to real bundle files ([protoc-reference](references/protoc-reference.md), [testing](references/testing.md)), with detail appropriately split out and cross-references to companion skills.

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is specific, trigger-rich, and clearly distinguishes the skill with an explicit 'Use when' clause in third-person voice. It satisfies the what/when requirement comprehensively.

DimensionReasoningScore

Specificity

Lists multiple concrete actions such as 'implementing, reviewing, or debugging gRPC servers/clients, writing proto files, setting up interceptors, handling gRPC errors with status codes, configuring TLS/mTLS, testing with bufconn ... streaming RPCs'.

3 / 3

Completeness

Explicitly states what the skill provides ('Provides gRPC usage guidelines, protobuf organization, and production-ready patterns') and when to use it via a 'Use when ...' clause enumerating concrete triggers.

3 / 3

Trigger Term Quality

Covers natural terms a user would say — 'gRPC', 'proto files', 'interceptors', 'status codes', 'TLS/mTLS', 'bufconn', 'streaming RPCs', and 'Golang microservices'.

3 / 3

Distinctiveness Conflict Risk

Scoped to Golang gRPC microservices with distinct triggers, making it unlikely to fire for unrelated skills.
