Auto-Skill - Proactive Learning System

You are now running Auto-Skill v5.0 - an active learning system that:

1. Observes your tool usage patterns in real-time
2. Detects repeated workflows (3+ occurrences)
3. Discovers relevant community skills from skills.sh
4. Recommends when to generate local skills vs use community skills
5. Learns continuously from your sessions

Optional Advanced Features

Auto-Skill is fully functional as-is, but offers optional CLI and MCP server for power users.

CLI Tools (Optional)

Install:

npm install -g @matrixy/auto-skill

Available commands:

• auto-skill init - Initialize config and directories
• auto-skill discover - Discover patterns for current project
• auto-skill stats - Show adoption statistics
• auto-skill graduate - Manage skill graduation

When to suggest CLI:

• User asks about "auto-skill commands" or "CLI"
• User asks about statistics or pattern analysis
• User wants to manage skill graduation

When to suggest Skills CLI instead:

• User wants to search for skills manually → npx skills find [query]
• User wants to install a specific skill → npx skills add owner/repo@skill
• User wants to list installed skills → npx skills list

How to offer:

Claude: "Auto-Skill provides CLI commands for terminal usage.
        Install with: npm install -g @matrixy/auto-skill"

MCP Server (Optional)

The MCP server enables programmatic access to Auto-Skill's search and discovery features.

Setup for Claude Code:

1. Install the package:

npm install -g @matrixy/auto-skill

2. Add to Claude Code MCP settings:

Open Claude Code settings and add:

{
  "mcpServers": {
    "auto-skill": {
      "command": "node",
      "args": ["/usr/local/lib/node_modules/@matrixy/auto-skill/dist/mcp/server.js"],
      "env": {
        "GITHUB_TOKEN": "ghp_your_token_here"
      }
    }
  }
}

Note: Adjust the path based on your npm global install location:

• macOS/Linux: Usually /usr/local/lib/node_modules/@matrixy/auto-skill/dist/mcp/server.js
• Windows: Usually %APPDATA%\npm\node_modules\@matrixy\auto-skill\dist\mcp\server.js
• Find it with: npm list -g @matrixy/auto-skill | head -1

3. Restart Claude Code to activate the MCP server

MCP Tools Available:

• search_skills - Search 27,000+ community skills
• discover_skills - Get context-aware recommendations

When to suggest MCP setup:

• User asks about "MCP server" or "MCP integration"
• User wants programmatic skill discovery
• User mentions they want to use Auto-Skill tools in other agents
• User asks "how do I use the search_skills tool?"

How to offer:

Claude: "Auto-Skill provides an MCP server for programmatic skill discovery.
        After installing npm package, add it to your Claude Code MCP settings.
        Would you like setup instructions?"

Active Capabilities

When this skill is loaded, you have access to:

Pattern Detection (Always Active)

• PostToolUse Hook: Records every tool call to ~/.claude/auto-skill/events.db
• Sequence Matching: Finds repeated patterns across sessions
• Confidence Scoring: Ranks patterns by occurrences, success rate, recency
• Auto-Generation: Creates skills from high-confidence patterns (70%+)

Proactive Discovery (NEW in v5.0)

• Context Analysis: Extracts frameworks, languages, intent from patterns
• Community Search: Searches 27,000+ skills on skills.sh
• Smart Recommendations: Suggests external skills vs local generation
• Graduation: Recommends upgrading local patterns to proven community skills

MCP Tools (Advanced Usage)

You have access to these MCP tools for programmatic skill discovery:

search_skills

Search community skills by query string:

{
  tool: "search_skills",
  arguments: {
    query: "react testing",
    limit: 5,
    includeContent: false
  }
}

discover_skills

Get context-aware skill recommendations:

{
  tool: "discover_skills",
  arguments: {
    frameworks: ["React", "Jest"],
    languages: ["TypeScript"],
    intent: "testing"
  }
}

When to use MCP tools:

• User explicitly asks to "search for skills"
• You detect a pattern and want to find community alternatives
• User wants recommendations for their current workflow
• Proactive discovery during multi-step tasks

How to Use This Skill

As Claude, You Should:

1. Observe Silently

   • Don't mention that you're recording patterns unless asked
   • The PostToolUse hook runs automatically after every tool call
   • Users will be notified when patterns reach suggestion threshold

2. Proactively Discover Skills

   • When a user requests a multi-step task, check if it matches a pattern
   • Search for relevant community skills BEFORE generating new ones
   • Example: User asks "help me test React components"
     • Search skills.sh for "react testing"
     • If found with high confidence (70%+), suggest: "I found 'React Test Patterns' with 1250 installs. Would you like me to use this community skill?"
     • If not found, generate a local skill as usual

3. Suggest Pattern Graduation

   • When a local pattern has 3+ occurrences AND a community skill exists with similar functionality
   • Example: "You've used this React testing workflow 5 times. There's a community skill 'React Test Patterns' that does the same thing. Should we graduate to using that instead?"

4. Load Skills Mid-Session

   • When a pattern is approved, load it immediately without session restart
   • Use the skill registry to fetch and format skill content

Pattern Detection Rules

Detection Triggers

Patterns are detected when:

• Same tool sequence appears 3+ times across sessions
• Sequence is 2-10 tools long
• Pattern occurred within last 7 days
• Confidence score ≥ 0.7 (70%)

Confidence Scoring

Factor	Weight	Range
Occurrences	40%	3 occurrences = 0.3, 10+ = 1.0
Sequence Length	20%	3-5 tools = 1.0, 1-2 or 8+ = 0.5
Success Rate	25%	100% success = 1.0
Recency	15%	Today = 1.0, 7 days ago = 0.3

Example Calculation:

Pattern: Grep → Read → Edit (5 occurrences, 3 tools, 100% success, 2 days ago)
- Occurrences: 0.5 × 0.4 = 0.20
- Length: 1.0 × 0.2 = 0.20
- Success: 1.0 × 0.25 = 0.25
- Recency: 0.7 × 0.15 = 0.105
Total Confidence: 0.755 (75.5%) ✅ Suggest to user

Proactive Discovery Workflow

When a pattern is detected, follow this workflow:

1. Extract Context
   ├─ Frameworks: [React, Jest, Testing Library]
   ├─ Languages: [TypeScript, JavaScript]
   └─ Intent: testing

2. Generate Search Queries
   ├─ "React testing"
   ├─ "Jest React Testing Library"
   └─ "React component testing"

3. Search skills.sh
   └─ GET /api/search?q=react+testing&limit=10

4. Rank Results
   ├─ Install count (50% weight)
   └─ Relevance score (50% weight)

5. Recommend
   ├─ If confidence ≥ 70%: Suggest graduation to external skill
   ├─ If confidence 50-70%: Show as alternative option
   └─ If confidence < 50%: Generate local skill as usual

Example Interactions

Scenario 1: Repeated Pattern Detected

After 3rd occurrence of Grep → Read → Edit:

Claude: I've noticed you've searched for files, read them, and edited them 3 times in similar ways.
        Would you like me to create a skill for this workflow?

User: Yes please

Claude: [Searches skills.sh for "search file edit"]
        I found "File Search & Edit Pattern" (820 installs) that matches your workflow.

        Install with: npx skills add vercel-labs/agent-skills@file-search-edit

        Would you prefer to:
        1. Use the community skill (recommended)
        2. Generate a custom skill based on your specific usage

Scenario 2: Proactive Discovery

User asks: "Help me test my React components"

Claude: [Searches skills.sh for "react testing", "react component testing"]
        I found "React Test Patterns" (1250 installs, 95% relevance).
        This skill provides:
        - Component test boilerplate
        - Mocking patterns for React hooks
        - Testing Library best practices

        Install with: npx skills add owner/repo@react-test-patterns

        Should I install this skill for you?

Scenario 3: Skill Graduation

User has local skill "my-react-tests" with 5 uses:

Claude: You've used your "my-react-tests" skill 5 times. I found a community skill
        "React Test Patterns" that covers the same patterns and has 1250 installs.

        Benefits of graduating:
        - Maintained by the community
        - Includes more test cases
        - Regular updates for new React features

        Install with: npx skills add owner/repo@react-test-patterns

        Would you like to graduate to the community skill?

Scenario 4: Manual Skill Search

User asks: "Are there any skills for testing?"

Claude: You can search for skills interactively with Skills CLI:

        npx skills find testing

        Or if you know what you're looking for:

        npx skills add owner/repo@skill-name

        Would you like me to search Auto-Skill's database for testing-related patterns instead?

Integration with Skills CLI

Auto-Skill complements the Skills CLI ecosystem rather than duplicating it.

How to Share a Generated Skill

When a user wants to share a valuable auto-generated skill:

1. Locate the skill:

ls ~/.claude/skills/auto/
# Example: grep-read-edit-workflow-abc123/SKILL.md

2. Review the skill:

• Check that it's generalizable (not project-specific)
• Ensure no sensitive data in examples
• Verify the description is clear

3. Publish to GitHub:

# Create a new repo for the skill
mkdir my-workflow-skill
cp ~/.claude/skills/auto/grep-read-edit-workflow-abc123/SKILL.md my-workflow-skill/
cd my-workflow-skill
git init
git add SKILL.md
git commit -m "Add auto-generated workflow skill"
gh repo create --public
git push

4. Submit to skills.sh: Visit skills.sh and submit the GitHub repo URL.

When to Suggest Sharing

Offer to help users share skills when:

• A skill has been used successfully 10+ times
• User says "this workflow is really useful"
• User asks "can others use this?"
• Skill has high confidence (85%+) and is domain-general

How to offer:

Claude: "This workflow has been really effective for you (12 uses, 89% confidence).
        Would you like to share it on skills.sh so others can benefit?
        I can help you prepare it for publishing."

Marketplace Vision

Auto-Skill enables a crowdsourced skill marketplace:

1. Users run Auto-Skill locally → workflows are detected
2. High-value patterns are refined and generalized
3. Users publish to GitHub + skills.sh
4. Others discover via Auto-Skill's proactive search
5. Community curates and improves shared workflows

This creates a flywheel: auto-detection → sharing → discovery → adoption.
