Skill Curator

Skill Curator — Find the Best Claude Code Skills

Discover the right Skills for any task from 117,000+ options, with quality verification powered by GitHub enrichment.

How It Works

1. Analyze your goal and break it into actionable tasks
2. Search the SkillsMP database (keyword + AI semantic search)
3. Verify each skill's quality via GitHub (stars, freshness, documentation, license)
4. Score skills on a 0–100 quality scale
5. Present a structured workflow plan with ranked recommendations

What Makes This Different

Unlike basic keyword search, every result is enriched with GitHub data and scored across 4 axes:

Prerequisites

Required: Apify MCP configured in your Claude Code environment.

Setup (one-time, ~3 minutes)

1. Get an Apify API token (free tier available)

   • Sign up at https://apify.com
   • Go to Settings → Integrations → API tokens
   • Create a new token and copy it

2. Add Apify MCP to your Claude Code settings

   Add the following to your Claude Code MCP settings (~/.claude/settings.json or project-level .claude/settings.json):

   {
     "mcpServers": {
       "apify": {
         "command": "npx",
         "args": ["-y", "@apify/actors-mcp-server"],
         "env": {
           "APIFY_TOKEN": "apify_api_YOUR_TOKEN_HERE"
         }
       }
     }
   }
   

3. Restart Claude Code to pick up the new MCP server

Verify Setup

After restarting, you can verify by asking Claude: "List available MCP tools". You should see mcp__apify__call_actor in the list.

Usage

/skill-curator [your goal]

Examples

/skill-curator Build a REST API with authentication and deploy to AWS
/skill-curator 技術書を執筆してPDF出版したい
/skill-curator Analyze CSV data and create interactive visualizations
/skill-curator Set up a CI/CD pipeline for a monorepo

Pricing

Each search costs approximately $0.15 on your Apify account (Pay-Per-Event billing). A typical invocation runs 1–3 searches depending on goal complexity.

Processing Instructions

When the user invokes this skill with $ARGUMENTS, follow these steps precisely.

Step 0: Preflight Check

Before searching, confirm Apify MCP is available by checking that you have access to the mcp__apify__call_actor tool. If the tool is not available, inform the user:

Apify MCP is not configured. Please follow the setup instructions:

1. Get a free Apify API token at https://apify.com (Settings → Integrations)
2. Add the Apify MCP server to your Claude Code settings (see README for details)
3. Restart Claude Code

Do NOT proceed without mcp__apify__call_actor access.

Step 1: Goal Analysis

Analyze the user's goal: $ARGUMENTS

Identify:

• Primary objective: The main thing they want to accomplish
• Secondary objectives: Supporting tasks implied by the goal
• Domain: Area this falls into (web dev, data, document, DevOps, etc.)
• Complexity: Simple (1-2 tasks) / Moderate (3-5) / Complex (6-8)

Step 2: Search Query Generation

Based on the analysis, generate 1 to 3 search queries in English:

• Primary query: Broad query covering the main goal (ALWAYS run this)
• Refinement query 1: Targeted at an under-covered sub-task (only if needed)
• Refinement query 2: For a specialized domain aspect (only if needed)

Guidelines for query generation:

• Use English for best results (SkillsMP index is English-dominant)
• Keep queries concise: 3-6 words work best for keyword search
• For complex/nuanced goals, enable AI semantic search (includeAiSearch: true)
• Use domain-specific terms (e.g., "REST API authentication" not "make secure backend")

Step 3: Call Skill Curator Actor

For each query, call the Apify Actor using the mcp__apify__call_actor tool:

Parameters:

• actorId: "C5SaxR8oWbctCy0Ai"
• input: JSON object with:
  • query (string, required): The search query
  • limit (number, optional, default 10): Max results (1-20)
  • includeAiSearch (boolean, optional, default false): Enable AI semantic search for better relevance (adds ~8s latency)
  • minStars (number, optional, default 0): Minimum GitHub stars filter

Example call:

mcp__apify__call_actor({
  actorId: "C5SaxR8oWbctCy0Ai",
  input: {
    "query": "REST API authentication middleware",
    "limit": 10,
    "includeAiSearch": true,
    "minStars": 0
  }
})

Cost optimization:

• For simple goals: 1 search with limit: 10
• For moderate goals: 1-2 searches with limit: 10
• For complex goals: 2-3 searches with limit: 10-15
• Enable includeAiSearch only when keyword results are likely insufficient (natural language queries, niche domains)

If multiple searches are needed and they are independent, run them in parallel.

Step 4: Process Enriched Results

The Actor returns enriched results with this structure per item:

{
  "name": "skill-name",
  "author": "author-name",
  "description": "...",
  "githubUrl": "https://github.com/...",
  "skillUrl": "https://skillsmp.com/...",
  "qualityScore": {
    "overall": 72,
    "popularity": 65,
    "freshness": 80,
    "documentation": 75,
    "license": 100
  },
  "repoMetadata": {
    "stars": 234,
    "forks": 12,
    "openIssues": 3,
    "license": "MIT",
    "lastPush": "2026-01-15T...",
    "topics": ["claude", "skill"]
  },
  "skillMdAnalysis": {
    "hasFrontmatter": true,
    "hasName": true,
    "hasDescription": true,
    "hasAllowedTools": true,
    "bodyLength": 2450,
    "hasExamples": true
  },
  "searchSource": "keyword"
}

Processing:

1. Aggregate results from all searches
2. Deduplicate by author/name (keep the one with higher qualityScore.overall)
3. Sort by qualityScore.overall descending
4. Map each result to the user's tasks based on description relevance

Step 5: Skill Selection

For each task in the workflow, select the best skill:

Selection criteria (in order of priority):

1. Relevance: Does the skill's description match the task?
2. Quality Score: Higher qualityScore.overall is better
3. Documentation: qualityScore.documentation ≥ 50 preferred (well-documented skills)
4. Freshness: qualityScore.freshness ≥ 60 preferred (actively maintained)
5. Author: anthropics (official) > well-known authors > others

Quality tiers:

• 🟢 80-100: Excellent — highly recommended
• 🟡 50-79: Good — solid choice
• 🟠 30-49: Fair — usable but check before relying on it
• 🔴 0-29: Low — consider alternatives

Step 6: Output Generation

CRITICAL: Language matching rule. Detect the language of the user's original prompt ($ARGUMENTS). The ENTIRE output — section headings, table headers, labels, and prose — MUST be written in that same language. Do NOT copy Japanese labels when the prompt is in English, and vice versa.

Below are two template variants. Use the one matching the detected language. For languages other than English or Japanese, follow the English template structure but translate all labels into the detected language.

Template A: English (use when prompt is in English)

検索サマリー

Notes

• Quality scores are calculated from real-time GitHub data (stars, last push, SKILL.md quality, license)
• AI semantic search is slower (~8s) but finds more relevant results for natural language queries
• Each search costs ~$0.15 on your Apify account
• This skill does NOT call other skills — it recommends them for you to install and use

Troubleshooting

"mcp__apify__call_actor not available"

• Verify Apify MCP is configured in your Claude Code settings
• Check the server name is "apify" (this determines the tool prefix)
• Restart Claude Code after configuration changes

Actor errors?

• Check your Apify token is valid at https://console.apify.com
• Ensure you have sufficient Apify credits (each run costs ~$0.15)

No relevant results?

• Try rephrasing your goal more specifically
• Enable AI semantic search for better relevance on complex queries
• Use English search terms for broader coverage

Unexpected quality scores?

• Quality scores use real-time GitHub data — scores change as repos are updated
• Skills without GitHub repos get lower scores (no enrichment data available)
• New skills may score low on popularity despite being high quality
