# Go Patterns Skill Umbrella skill for Go development: Google style, testing, concurrency, error handling, failure modes, code review, SAP CC conventions, and quality gates. Load the references relevant to the task. ## Google Style Precedence Use this precedence when guidance differs: 1. The target repository's explicit rules and required compatibility constraints. 2. The Google Go Style Guide's canonical rules. 3. Google Go Style Decisions' normative guidance. 4. Google Go Style Best Practices' non-canonical recommendations. 5. Task-specific references below. Prefer local consistency only where the Google guide allows judgment. Do not create unrelated churn merely to restyle existing code. For new and nearby changed code, follow the current pinned guidance. Record a conscious exception when repository rules, generated-code constraints, or compatibility requirements require one. ## Reference Loading Table | Signal | Load These Files | Why | |---|---|---| | Google-specific style decisions | Relevant sections under `google-style-guide/` | Check the pinned conventions needed for the task | | Testing | `testing.md` | Writing, fixing, or reviewing Go tests | | Concurrency | `concurrency.md` | Goroutines, channels, sync primitives, race conditions | | Error handling | `error-handling.md` | Error wrapping, sentinels, custom types, errors.Is/As | | Review patterns | `preferred-patterns.md` | Detecting code smells, over-engineering, bad Go patterns | | Code review | `code-revie...
