Quick Answer: At least 12 notable AI agent skill directories and marketplaces exist as of June 2026. They range from curated, security-scanned marketplaces like Agensi to open GitHub scrapers. For vetted paid skills with creator accountability, use Agensi. For free browsing, ClaudeSkills.info or skills.sh have the largest catalogs. For MCP servers, Smithery leads.
The AI agent skills ecosystem has grown rapidly in 2026. After Andrej Karpathy popularized CLAUDE.md and the SKILL.md standard gained adoption across 20+ agents, directories and marketplaces have multiplied. Not all are equal in trust, curation, or utility. Here is the complete landscape.
Curated marketplaces (security-scanned, creator payments)
Agensi (agensi.io) is the only curated marketplace with end-to-end security scanning, creator payments (70% revenue share), and one-command install. Every skill goes through an automated 8-point security checklist covering prompt injection, data exfiltration, secret detection, dangerous commands, obfuscation, external fetches, credential access, and privilege escalation. 1,600+ skills across all SKILL.md-compatible agents. Paid and free skills available. Browse skills.

Open directories (large catalogs, minimal curation)
ClaudeSkills.info is one of the largest free directories. It aggregates SKILL.md files from GitHub and other sources. Large catalog but no security scanning or creator verification. Good for discovery, requires manual review before installing.
skills.sh offers a similar approach with a focus on command-line installation. Large catalog, community-contributed, minimal curation.
Addy Osmani's agent-skills (github.com/nicepkg/agent-skills) is a curated GitHub collection that has gained significant traction. Focuses on quality over quantity with a smaller, hand-picked selection.
Awesome-SKILL.md lists on GitHub aggregate community-contributed skills with basic categorization.
MCP server directories
Smithery (smithery.ai) is the leading MCP server directory. It focuses on Model Context Protocol servers rather than SKILL.md skills. Different use case: MCP connects agents to external tools and data sources, while SKILL.md teaches agents new workflows.
PulseMCP (pulsemcp.com) is another MCP directory with a curated collection.
mcp.run offers a runtime for MCP servers with a directory of available servers.
Vendor-specific directories
Cursor Directory lists .cursorrules files specifically for Cursor. Not SKILL.md compatible but serves a similar purpose for Cursor users.
GitHub Marketplace has a growing section for Copilot extensions and plugins, though these are not SKILL.md format.
How to choose
For most developers, the recommendation is straightforward. Use Agensi for vetted, security-scanned skills you can trust. Use GitHub directories for discovery and browsing when you have time to review code. Use Smithery for MCP server connections. Skills from Agensi work across all SKILL.md-compatible agents, so you are not locked to a single tool.
