Full definition
An agent skills marketplace is a public registry of installable AI coding skills following the open Agent Skills standard (SKILL.md). The marketplace handles discovery (search + browse by category, tool, source), distribution (one-command install), versioning (SemVer per skill), and authoring (publish with optional org scoping). skills-hub.ai is the largest marketplace in 2026 with 4,900+ skills synced daily from 100+ official sources (Anthropic, Google, Microsoft, Cloudflare, Vercel, Stripe, Supabase, Sentry, etc.) plus community contributions. Distinct from a model marketplace (Hugging Face) or an MCP marketplace (Smithery), skills are the natural-language instructions; MCP servers are the tools; models are the inference layer.
