Lesson 9Claude Skills

Claude Skills Marketplace

Beyond building your own skills, five community platforms let you discover, browse, and install thousands of ready-made skills and MCP tools for Claude Code and other AI agents — from AI-graded curated directories to million-skill GitHub indexes and MCP marketplaces with managed auth.

SkillHubskillhub.club

SkillHub is a curated skills directory where every skill is graded by AI across five dimensions: Practicality, Clarity, Automation, Quality, and Impact. S-rank skills (9.0+) are the best of the best. You can browse by category (Development, Frontend, Backend, Data, AI/ML), search semantically, or install via the CLI in one command.

SkillsMPskillsmp.com

SkillsMP aggregates over 1.1 million skills from public GitHub repositories. It's the largest collection available and indexes skills compatible with Claude Code, OpenAI Codex CLI, and other tools that support the open SKILL.md standard. You can browse by occupation (23 major groups, 867 SOC categories) or by use-case category, and a public REST API lets you query the catalogue programmatically.

SkillsMP does not have a dedicated CLI — you find the skill, clone the repository, and copy the skill folder into your skills directory:

# Find the skill on skillsmp.com, copy the GitHub repo URL, then:
$ git clone https://github.com/obra/superpowers
$ cp -r superpowers/systematic-debugging ~/.claude/skills/
✔ Skill available as /systematic-debugging
ℹ️ Info: SkillsMP is an independent community project and is not affiliated with Anthropic. Always review skill content before installing — treat community skills like any open-source code.

Smitherysmithery.ai

Smithery is primarily an MCP (Model Context Protocol) marketplace — 7,887+ servers covering tools like GitHub, Notion, Supabase, Slack, and Google Sheets. It also has a growing Skills section. What makes Smithery different is its auth handling: install a tool once and Smithery manages OAuth, credential injection, and retries across Claude, GPT, and other agents automatically.

Set up Smithery's CLI and add an MCP to Claude in two commands:

# One-time CLI setup
$ npx -y smithery setup
# Add a tool (Smithery handles auth for you)
$ npx smithery mcp add notion
→ auth_required
→ https://auth.smithery.ai/... ← visit to authorize
✔ notion connected
💡 Tip: Use SkillHub or SkillsMP to find Claude-specific SKILL.md skills. Use Smithery when you need to connect Claude to external services (GitHub, Notion, Slack) with managed auth — it handles the OAuth plumbing so you don't have to.

More MCP directories

If you need to browse MCP servers beyond what Smithery lists, two more community directories cover a wider catalogue. Neither hosts Claude SKILL.md skills directly, but both are useful when hunting for tool integrations.

mcp.so20K+ MCPs
mcp.so · community-driven

A community-run MCP discovery site with 20,617+ servers. Supports filtering by featured, hosted, and official servers. No CLI — browse and copy configs manually. Includes a playground for testing servers in the browser.

Review any SKILL.md before installing — check the allowed-tools field in particular to understand what shell commands the skill can run.

The marketplace shows what's possible. Now let's focus on writing instructions that are clear, reliable, and produce consistent results.
