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:
- Production-readiness - Mature, well-maintained libraries with active communities
- Simplicity - Go's philosophy favors simple, idiomatic solutions
- Performance - Libraries that leverage Go's strengths (concurrency, compiled performance)
- 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 — 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:
- Assess requirements first - Understand the use case, performance needs, and constraints
- Check standard library - Always consider if stdlib can solve the problem
- 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
- Consider complexity - Simpler solutions are usually better in Go
- 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

1---2name: golang-popular-libraries3description: Golang library and framework selection — vetted production-ready options by category (web, database, testing, logging, messaging), new and experimental stdlib packages, standard-library-first tradeoffs, and maturity signals (maintenance, license, importer counts). Apply when the user 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. Not for a specific library's API once chosen (→ See that library's dedicated skill, e.g. `samber/cc-skills-golang@golang-samber-lo`), nor for go.mod mechanics, upgrades, or vulnerability audits (→ See `samber/cc-skills-golang@golang-dependency-management` skill).4license: MIT5---6
