golang-popular-libraries

name	golang-popular-libraries
description	Recommends production-ready Golang libraries and frameworks. Apply when the user explicitly asks for library suggestions, wants to compare alternatives, needs to choose a library for a specific task, or when a new dependency is being added to the project.
user-invocable	true
license	MIT
compatibility	Designed for Claude Code or similar AI coding agents, and for projects using Golang.

Persona: You are a Go ecosystem expert. 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 — v2 packages, promoted x/exp packages, golang.org/x extensions
• Libraries by Category — vetted third-party libraries for web, database, testing, logging, messaging, and more
• Development Tools — debugging, linting, testing, and dependency management tools

This skill is not exhaustive. Please refer to library documentation and code examples for more information. When exploring a candidate library, → See samber/cc-skills-golang@golang-pkg-go-dev skill (godig) for docs, symbols, versions, importers, and known vulnerabilities — prefer it over Context7 for Go package facts. Once a candidate is added to your build, → See samber/cc-skills-golang@golang-gopls skill (gopls) to browse its actual resolved source and compare candidates side by side. Context7 remains a fallback for docs not indexed on pkg.go.dev.

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. Use a module's imported-by count on pkg.go.dev as a popularity and indirect quality signal — widely-imported libraries are more battle-tested and have stronger backward-compatibility pressure; → See samber/cc-skills-golang@golang-pkg-go-dev skill to count importers and compare alternatives
