External Skills Catalog

Curated directory of community and official Claude Code skills. Use this when the user needs a capability that vibecosystem doesn't cover natively, or when recommending external tools.

When to Use

User asks for a skill/capability that doesn't exist in vibecosystem
User wants to discover what else is available for Claude Code
Recommending complementary skills for a specific workflow
Fallback when internal skills can't fully handle a request

Quality Ranking

Skills are ranked by reliability and maintenance:

Tier	Label	Criteria
1	Official	Made by Anthropic or verified partners
2	Well-starred	50+ GitHub stars, active maintenance, good docs
3	Community	Open source, functional, may lack polish

Always prefer higher-tier skills. Mention tier when recommending.

Install Instructions

Claude Code (CLI)

# MCP-based skills: add to ~/.claude/mcp.json or project .mcp.json
{
  "mcpServers": {
    "skill-name": {
      "command": "npx",
      "args": ["-y", "@package/mcp-server"]
    }
  }
}

# Prompt-based skills: add to ~/.claude/commands/ or project .claude/commands/
mkdir -p .claude/commands
echo "skill content here" > .claude/commands/skill-name.md

Claude.ai (Web)

MCP skills can be added via Settings > Integrations > MCP Servers.

Fallback Strategy

When the needed skill doesn't exist:

Step 1: WORKAROUND
  → Can an existing vibecosystem skill handle it partially?
  → Example: No "email" skill? Use copywriter agent + manual send

Step 2: COMBO
  → Can 2+ existing skills combine to solve it?
  → Example: No "API mock" skill? Use mocksmith + backend-dev

Step 3: CREATE
  → Is it worth creating a new internal skill?
  → Use /skill-create to generate from session patterns

Step 4: EXTERNAL
  → Search this catalog for a community skill
  → Check: https://github.com/topics/claude-code
  → Check: https://github.com/topics/mcp-server
  → Web search: "claude code [capability] skill 2026"

Discovering New Skills

The external ecosystem grows fast. When this catalog doesn't have what you need:

Search GitHub: claude code skill [keyword] or mcp server [keyword]
Check MCP server directories for new integrations
Look at Claude Code community discussions
Consider building and contributing your own

Tips

Always verify external skills before recommending (check repo activity, stars, last commit)
Prefer MCP-based skills for deeper integration
Prompt-based skills are easier to install but less powerful
When recommending, include the install command so the user can act immediately
If a skill has known issues, mention them upfront
