What problem does it solve? Go developers building microservices, REST APIs, and CLI tools often need consistent, idiomatic patterns for web frameworks, database access, and concurrent programming. This Skill provides structured guidance and production-ready code patterns for Go 1.23+ development, reducing time spent searching documentation and avoiding common pitfalls in error handling, concurrency, and deployment. ## Core Features & Use Cases - Web Framework Patterns: Complete routing, middleware, and request-binding examples for Fiber v3, Gin, Echo, and Chi, including validation and error handling. - Database & ORM Guidance: GORM model definitions, query patterns, transactions, and raw SQL with pgx connection pooling for PostgreSQL. - Concurrency Patterns: Errgroup, worker pools, semaphores, and fan-out/fan-in implementations with context-based cancellation and timeouts. - Use Case: When building a high-performance REST API in Go, ask for a Fiber application scaffold and receive a complete structure with middleware, graceful shutdown, PostgreSQL integration, and a minimal multi-stage Dockerfile producing a 10-20MB container image. ## Quick Start Ask the assistant to create a Go REST API with Fiber and PostgreSQL including graceful shutdown and Docker deployment.
