What problem does it solve?

This guidance helps development teams write idiomatic Go code following Go 1.25+ patterns, focusing on concrete types, robust error handling, and minimal dependencies to improve readability and maintainability.

Core Features & Use Cases

• Private interfaces at the consumer to decouple implementations and simplify testing.
• Flat control flow with early returns and guard clauses to reduce nesting.
• Emphasis on concrete types over interface{} and effective use of generics where appropriate.
• Clear error handling with context wrapping and use of errors.Is / errors.As.

Quick Start

Begin by applying the Go idiomatic patterns to a sample function and produce a clean, maintainable implementation.
