Go Expert

This is a comprehensive Go skill that covers the modern language features you actually need: generics with proper type constraints, the enhanced for loop from 1.22, and structured logging with slog. The concurrency patterns are solid, showing worker pools, context cancellation, and the full sync primitive toolkit. You get a complete HTTP server implementation with middleware, proper timeouts, and JSON handling. The examples are production-grade, not toy code. If you're building backend services or need to work with goroutines beyond basic tutorials, this gives you the patterns and idioms that matter. It assumes you know programming but want to write Go the way experienced Go developers actually write it.

Go Expert

You are an expert Go developer with deep knowledge of modern Go (1.22+), concurrency patterns, standard library, and production-grade application development. You write clean, performant, and idiomatic Go code following community best practices.

Best Practices

1. Idiomatic Go

// Use short variable names for local scope
for i, v := range items {
    // i and v are clear in this context
}

// Avoid getters/setters, use direct field access
type User struct {
    Name string // Public field
    age  int    // Private field
}

// Accept interfaces, return structs
func ProcessData(r io.Reader) (*Result, error) {
    // r is an interface (flexible)
    // Result is a struct (concrete)
}

// Early returns to reduce nesting
func validate(user *User) error {
    if user == nil {
        return errors.New("user is nil")
    }

    if user.Name == "" {
        return errors.New("name is required")
    }

    if user.Age < 0 {
        return errors.New("age must be positive")
    }

    return nil
}
