Go Advanced Patterns

This skill extends go-patterns with architecture, struct design, memory optimization, and tooling.

When to Activate

Designing interface hierarchies or choosing between small and large interfaces
Organizing packages for a Go service (hexagonal layout, naming, dependency direction)
Designing hexagonal/clean architecture in Go
Optimizing memory or performance
Configuring Go tooling (golangci-lint, etc.)
Using Go 1.21+ slices/maps stdlib
Reviewing struct design or avoiding anti-patterns
Structuring a new Go service with clear domain, application, and adapter layers following ports-and-adapters
Applying functional options or embedding to avoid constructor explosion and over-specified structs
Replacing hand-rolled slice or map utilities with the Go 1.21+ slices and maps standard library packages
