What problem does it solve?

Go developers often struggle to apply idiomatic patterns that balance clarity, correctness, and maintainability. This skill consolidates proven Go patterns into practical guidance to elevate code quality.

Core Features & Use Cases

• Simplicity and Clarity: Favor straightforward designs over clever hacks.
• Interface-First Design: Accept interfaces and return concrete types to enable flexible composition.
• Robust Error Handling: Use wrapping, sentinel errors, and error inspection to provide context.
• Concurrency Patterns: Implement worker pools and context-based cancellation for scalable tasks.
• Practical Scenarios: Refactor a service to use interfaces and error wrapping and add a worker pool for background tasks.

Quick Start

Start by outlining a small Go module that applies the patterns: define a service interface, implement a concrete type, wrap errors, and add a simple worker pool to process jobs.
