API Development

Writes idiomatic, production-quality Go code using modern concurrency patterns and robust error handling.

About

This skill empowers Claude with deep Go (Golang) expertise, enabling it to assist with complex development tasks including concurrency orchestration via channels and goroutines, implementing the functional options pattern, and managing dependencies with Go modules. It enforces 'Effective Go' principles, helping developers avoid common anti-patterns such as goroutine leaks or interface misusage, while providing templates for high-performance testing and structured logging with the slog library.

Key Features

Advanced error handling strategies utilizing wrapping, sentinel errors, and custom types
Comprehensive testing templates for table-driven unit tests and performance benchmarks
Standardized project structure and module management following Go community best practices
0 GitHub stars
Implementation of idiomatic Go concurrency patterns including worker pools and context cancellation
Production-ready HTTP handler patterns and structured logging with the slog package

Use Cases

Building scalable microservices with clean API architectures and efficient concurrency
Refactoring legacy Go code to follow modern 'Effective Go' idiomatic standards
Debugging performance bottlenecks or goroutine leaks in complex distributed systems
