What problem does it solve?
Solo builders drown in one-off GitHub skills and cannot quickly find versioned, categorized Claude plugins for RBAC, UI kits, or AI chat patterns.
Who is it for?
Claude Code users who want a broad, keyword-indexed plugin library and pick tools per feature sprint.
Skip if: Builders who need a single opinionated workflow (for example only Medusa ecommerce or only Defang deploy) without browsing a large catalog.

Agent MarketplaceMrMYHuang/agent-marketplace
Journey fit
Primary fit
The catalog's breadth maps to implementation work—pick plugins as you build features—so build is the canonical hub shelf even though individual plugins span ship and security. integrations fits a mega-marketplace where you attach specialized plugins (RBAC, Aceternity UI, AI elements) into an existing app rather than one monolithic skill.
How it compares
Large curated multi-domain marketplace, not a single-vendor deploy stack or a four-plugin commerce bundle.

Claude Skills is for solo builders and small teams using Claude Code who want many optional plugins—security, UI, AI, and more—from one maintained marketplace.
When should I use Claude Skills?
Use it whenever you need a specialized Claude plugin during build, ship, or growth work and prefer enabling named plugins from a 170-item catalog instead of cloning repos.
How do I add Claude Skills to my agent?
