What is the 'accept interfaces, return structs' pattern?

This Go-specific pattern suggests that functions should take interfaces as parameters to increase flexibility (decoupling) but return concrete types to make the API easier to use and more predictable.

How does this skill handle Go error management?

It implements modern error handling using context-aware wrapping (fmt.Errorf with %w), type assertions with errors.As, and value checks with errors.Is to ensure errors are never ignored.

Does it support Go performance optimization?

The skill includes specific guidance on pre-allocating slices to avoid re-allocations, using strings.Builder for efficient concatenation, and utilizing sync.Pool for frequent object reuse.

Can this skill help prevent goroutine leaks?

Yes, it provides patterns for safe concurrency that include context-based cancellation, buffered channels, and proper cleanup to ensure goroutines exit correctly when no longer needed.

API Development

Implements idiomatic Go patterns, best practices, and robust implementation guidelines for building efficient and maintainable applications.

The golang-patterns skill serves as a comprehensive guide for developers using Claude Code to write high-quality Go code. It enforces core language philosophies such as simplicity over cleverness, making zero values useful, and the 'accept interfaces, return structs' principle. By providing standardized patterns for error handling with context, advanced concurrency models like worker pools and errgroup, and structural designs like functional options, this skill ensures that generated Go code is production-ready, performant, and follows community-accepted conventions.
