# Golang > Go coding conventions, idiomatic patterns, and CLI commands reference. Follows Effective Go and Go Code Review Comments strictly. Trigger on any Go-related question — code style, error handling, concurrency, project structure, go mod, testing, etc. Use when this capability is needed. - Skill: `tomevault-io/golang-4` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add tomevault-io/golang-4` - Raw SKILL.md: https://api.skillmd.com/api/skills/tomevault-io/golang-4/raw - Safety review: pending (external: skill-scanner PASS, skillspector PASS) - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Coding & Dev Tools - Author: tomevault-io (https://skillmd.com/u/tomevault-io) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/tomevault-io/golang-4 --- # Golang Skill Go best practices, idiomatic patterns, and toolchain reference. Strictly follows [Effective Go](https://go.dev/doc/effective_go) and [Go Code Review Comments](https://go.dev/wiki/CodeReviewComments). ## How to use this skill Read the relevant reference file based on the user's question: ### 1. [Rules](../../rules/golang/rules.md) Read when writing or reviewing Go code — naming, formatting, error handling, documentation, package design. Covers: - Naming conventions (MixedCaps, acronyms, interface names) - Error handling (don't panic, wrap errors, sentinel errors) - Package design (small, focused, no circular deps) - Documentation comments (godoc format) - Import organization and blank imports - Variable declaration style - Receiver naming and type ### 2. [Patterns](references/patterns.md) Read when implementing Go features or asking about idiomatic Go approaches. Covers: - Interface design (small interfaces, accept interfaces return structs) - Concurrency (goroutines, channels, sync primitives, context) - Error patterns (custom errors, error wrapping, errors.Is/As) - Functional options pattern - Table-driven tests - Struct embedding - init() and package initialization - Graceful shutdown ### 3. Commands Read when the user needs Go build or test commands. - [go-build](../../commands/golang/go-build.md) — go build, cross-compilation, build tags, ldflags - [go-test](../../commands/golang/go-test.md) — go test, coverage, benchmarks, fuzzing --- > Source: [pkc918/reactor](https://github.com/pkc918/reactor) — distributed by [TomeVault](https://tomevault.io).
