Full definition
A skill marketplace (or skill registry) is a public catalog of AI agent skills you can browse, search, install, and contribute to. Skills-hub.ai is the largest in 2026, with skills synced daily from 198 official sources (Anthropic, Google, Microsoft, Cloudflare, Vercel, Stripe, Supabase, Sentry, etc.) plus community contributions. Other registries exist (LobeHub's agent skills marketplace, vendor-specific catalogs) but skills-hub is tool-agnostic, every skill works in every major AI coding tool via the open Agent Skills standard.
