$npx -y skills add samber/cc-skills-golang --skill golang-popular-librariesRecommends 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.
| 1 | **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. |

| 4 | |
| 5 | ## Core Philosophy |
| 6 | |
| 7 | When recommending libraries, prioritize: |
| 8 | |
| 9 | 1. **Production-readiness** - Mature, well-maintained libraries with active communities |
| 10 | 2. **Simplicity** - Go's philosophy favors simple, idiomatic solutions |
| 11 | 3. **Performance** - Libraries that leverage Go's strengths (concurrency, compiled performance) |
| 12 | 4. **Standard Library First** - SHOULD prefer stdlib when it covers the use case; only recommend external libs when they provide clear value |
| 13 | |
| 14 | ## Reference Catalogs |
| 15 | |
| 16 | - [Standard Library - New & Experimental](./references/stdlib.md) — v2 packages, promoted x/exp packages, golang.org/x extensions |
| 17 | - [Libraries by Category](./references/libraries.md) — vetted third-party libraries for web, database, testing, logging, messaging, and more |
| 18 | - [Development Tools](./references/tools.md) — debugging, linting, testing, and dependency management tools |

| 22 | 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. |

| 24 | ## General Guidelines |
| 25 | |
| 26 | When recommending libraries: |
| 27 | |
| 28 | 1. **Assess requirements first** - Understand the use case, performance needs, and constraints |
| 29 | 2. **Check standard library** - Always consider if stdlib can solve the problem |
| 30 | 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 |
| 31 | 4. **Consider complexity** - Simpler solutions are usually better in Go |
| 32 | 5. **Think about dependencies** - More dependencies = more attack surface and maintenance burden |
| 33 | |
| 34 | Remember: The best library is often no library at all. Go's standard library is excellent and sufficient for many use cases. |
| 35 | |
| 36 | ## Anti-Patterns to Avoid |
| 37 | |
| 38 | - Over-engineering simple problems with complex libraries |
| 39 | - Using libraries that wrap standard library functionality without adding value |
| 40 | - Abandoned or unmaintained libraries: ask the developer before recommending these |
| 41 | - Suggesting libraries with large dependency footprints for simple needs |
| 42 | - Ignoring standard library alternatives |
