You know the library landscape well enough to recommend the simplest production-ready option — and to tell the developer when the standard library is already enough. # Go Libraries and Frameworks Recommendations ## Core Philosophy When recommending libraries, prioritize: 1. **Production-readiness** - Mature, well-maintained libraries with active communities 2. **Simplicity** - Go's philosophy favors simple, idiomatic solutions 3. **Performance** - Libraries that leverage Go's strengths (concurrency, compiled performance) 4. **Standard Library First** - SHOULD prefer stdlib when it covers the use case; only recommend external libs when they provide clear value ## Reference Catalogs - [Standard Library - New & Experimental](./references/stdlib.md) — v2 packages, promoted x/exp packages, golang.org/x extensions - [Libraries by Category](./references/libraries.md) — vetted third-party libraries for web, database, testing, logging, messaging, and more - [Development Tools](./references/tools.md) — debugging, linting, testing, and dependency management tools Find more libraries here: This skill is not exhaustive. Please refer to library documentation and code examples for more information. ## General Guidelines When recommending libraries: 1. **Assess requirements first** - Understand the use case, performance needs, and constraints 2. **Check standard library** - Always consider if stdlib can solve the problem 3. **Prioritize maturity** - MUST check maintenance status, license, and community adoption before recommending 4. **Consider complexity** - Simpler solutions are usually better in Go 5. **Think about dependencies** - More dependencies = more attack surface and maintenance burden Remember: The best library is often no library at all. Go's standard library is excellent and sufficient for many use cases. ## Anti-Patterns to Avoid - Over-engineering simple problems with complex libraries - Using libraries that wrap standard library functionality without adding value - Abandoned or unmaintained libraries: ask the developer before recommending these - Suggesting libraries with large dependency footprints for simple needs - Ignoring standard library alternatives ## Cross-References - → See `samber/cc-skills-golang@golang-dependency-management` skill for adding, auditing, and managing dependencies - → See `samber/cc-skills-golang@golang-samber-do` skill for samber/do dependency injection details - → See `samber/cc-skills-golang@golang-samber-oops` skill for samber/oops error handling details - → See `samber/cc-skills-golang@golang-stretchr-testify` skill for testify testing details - → See `samber/cc-skills-golang@golang-grpc` skill for gRPC implementation details
