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 4,900+ skills synced daily from 100+ 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.
