golang-lint

Linting best practices and golangci-lint configuration for Golang projects — running linters, configuring .golangci.yml, suppressing warnings with nolint directives, interpreting lint output, and selecting linters. Use when configuring golangci-lint, asking about lint warnings or nolint suppressions, setting up code quality tooling, or choosing linters. Also use when the user mentions golangci-lint, go vet, staticcheck, or revive.

golang-how-to

Golang skills orchestrator — always active on any Golang coding, review, debug, or setup task. Reads the task context and loads the most relevant skills from samber/cc-skills-golang, often multiple at once: writing a gRPC service loads golang-grpc + golang-testing + golang-error-handling; debugging a panic loads golang-troubleshooting + golang-safety; auditing security loads golang-security + golang-lint + golang-safety. Also: disambiguates competing clusters when two skills seem to overlap (performance vs benchmark vs troubleshooting, samber/lo vs mo vs ro, DI cluster, safety vs security), and configures CLAUDE.md or AGENTS.md to force-trigger skills in a project (/golang-how-to configure).

golang-project-layout

Provides a guide for setting up Golang project layouts and workspaces. Use when starting a new Go project, organizing an existing codebase, setting up a monorepo with multiple packages, creating CLI tools with multiple main packages, deciding between cmd/internal/pkg directory conventions, or discussing package restructuring, package splits, or module splits.

Go gRPC Best Practices

Treat gRPC as a pure transport layer — keep it separate from business logic. The official Go implementation is google.golang.org/grpc.

This skill is not exhaustive. Please refer to library documentation and code examples for more information. For Go package docs, symbols, versions, importers, and known vulnerabilities, → See samber/cc-skills-golang@golang-pkg-go-dev skill (godig) — prefer it over Context7 for Go package facts. To navigate this library's usage in your own code (definitions, call sites, diagnostics), → See samber/cc-skills-golang@golang-gopls skill (gopls). Context7 remains a fallback for docs not indexed on pkg.go.dev.

Code	When to Use
`InvalidArgument`	Malformed input (missing field, bad format)
`NotFound`	Entity does not exist
`AlreadyExists`	Create failed, entity exists
`PermissionDenied`	Caller lacks permission
`Unauthenticated`	Missing or invalid token
`FailedPrecondition`	System not in required state
`ResourceExhausted`	Rate limit or quota exceeded
`Unavailable`	Transient issue, safe to retry
`Internal`	Unexpected bug
`DeadlineExceeded`	Timeout

Pattern	Use Case
Server streaming	Server sends a sequence (log tailing, result sets)
Client streaming	Client sends a sequence, server responds once (file upload, batch)
Bidirectional	Both send independently (chat, real-time sync)

Setting	Purpose	Typical Value
`keepalive.ServerParameters.Time`	Ping interval for idle connections	30s
`keepalive.ServerParameters.Timeout`	Ping ack timeout	10s
`grpc.MaxRecvMsgSize`	Override 4 MB default for large payloads	16 MB
Connection pooling	Multiple conns for high-load streaming	4 connections

Common Mistakes

Cross-References

Mistake	Fix
Returning raw `error`	Becomes `codes.Unknown` — client can't decide whether to retry. Use `status.Errorf` with a specific code
No deadline on client calls	Slow upstream hangs indefinitely. Always `context.WithTimeout`
New connection per request	Wastes TCP/TLS handshakes. Create once, reuse — HTTP/2 multiplexes RPCs
Reflection enabled in production	Lets attackers enumerate every method. Enable only in dev/staging
`codes.Internal` for all errors	Wrong codes break client retry logic. `Unavailable` triggers retry; `InvalidArgument` does not
Bare types as RPC arguments	Can't add fields to `string`. Wrapper messages allow backwards-compatible evolution
Missing health check service	Kubernetes can't determine readiness, kills pods during deployments
Ignoring context cancellation	Long operations continue after caller gave up. Check `ctx.Err()`
