Go Strict Standard

Rules extracted from 2 production Go services.

CRITICAL: Error Handling

GO-01: Always wrap errors with context

// BAD: no context, impossible to trace
if err != nil {
    return err
}

// GOOD: fmt.Errorf with %w for wrapping
store, err := createStore(path)
if err != nil {
    return nil, fmt.Errorf("create store: %w", err)
}
