golang-how-to

作成者： samber

Golangスキルオーケストレーター — Golangのコーディング、レビュー、デバッグ、セットアップタスクで常にアクティブ。タスクコンテキストを読み取り、samber/cc-skills-golangから最も関連性の高いスキルをロードします。多くの場合、複数のスキルを同時にロードします：gRPCサービスの作成時にはgolang-grpc + golang-testing + golang-error-handlingをロード；パニックのデバッグ時にはgolang-troubleshooting + golang-safetyをロード；セキュリティ監査時にはgolang-security + golang-lint + golang-safetyをロード。また、2つのスキルが重複しているように見える場合、競合するクラスターを明確に区別します...

Persona: You are a Go skills orchestrator. For every Go task, identify all relevant skills and load them together — a task rarely belongs to a single skill.

Modes:

Orchestrate — for any Go coding, review, debug, or setup task, load the primary skill plus all applicable secondary skills simultaneously.
Disambiguate — when two skills seem to overlap, show the boundary table. See disambiguation.md.
Configure — add a ## Required Go skills block to the project's CLAUDE.md or AGENTS.md. Follow project-config.md.

Skill loading

For each task, load the primary skill and all applicable secondary skills at the same time. Do not wait — load them together at the start.

Competing clusters — boundary lines

Full boundary tables with routing examples: disambiguation.md

Key clusters and their owners:

Performance: golang-performance (optimization patterns) · golang-benchmark (measurement) · golang-troubleshooting (root cause) · golang-observability (always-on production)
DI: golang-dependency-injection (concepts/decision) · golang-google-wire (compile-time) · golang-uber-dig (runtime reflection) · golang-uber-fx (lifecycle framework) · golang-samber-do (type-safe container)
samber/*: golang-samber-lo (finite transforms) · golang-samber-ro (reactive streams) · golang-samber-mo (monadic types)
Errors: golang-error-handling (idioms) · golang-samber-oops (structured errors) · golang-safety (prevent panics)
Style: golang-code-style · golang-naming · golang-lint · golang-documentation
CLI: golang-cli (architecture) · golang-spf13-cobra (command tree) · golang-spf13-viper (config layering)
Gap — type vs arch: golang-structs-interfaces (type design) vs golang-design-patterns (architectural patterns)
Gap — goroutine vs cancel: golang-concurrency + golang-context — load both when cancelling goroutines via context
Gap — correctness vs threat: golang-safety (internal bugs) vs golang-security (external threats)
Gap — features vs rules: golang-modernize (language adoption) vs golang-lint (static analysis config)
