Clean up all README files to focus on user value rather than research metrics. Remove telemetry numbers and research context that isn't useful for end users. ## Changes **Main README.md**: - Removed "Based on 447,557 real MCP tool usage events" section - Replaced failure rate metrics with user benefits - Removed entire "Data-Driven Design" section with telemetry statistics - Fixed all GitHub links to use czlonkowski/n8n-mcp - Updated "Repository Stats" to "What's Included" with user-focused content **dist/README.md**: - Changed "HIGHEST PRIORITY" to "recommended to install first" - Added link to n8n-mcp repository - More user-friendly language throughout **Skill README.md files**: - n8n-mcp-tools-expert: Removed "447,557 events", "20% failure rate" metrics - n8n-workflow-patterns: Removed "Based on 31,917 real workflows" - n8n-validation-expert: Removed "From 7,841 validate → fix cycles" - Replaced frequency percentages with priority levels (Highest/High/Medium/Low) - Reframed "Success Metrics" as "What You'll Learn" - Changed "Critical Insights from telemetry" to "Key Insights" for users ## Kept What Matters - Template counts (2,653+) - this is a feature, not research - Node counts (525+) - this is a feature - Practical insights (validation takes 2-3 iterations, false positives exist) - Best practices and common patterns ## Result Documentation now focuses on what users need to know to use the skills effectively, rather than the research that informed their creation.

Expert Claude Code skills for building flawless n8n workflows using the n8n-mcp MCP server
🎯 What is this?
This repository contains 5 complementary Claude Code skills that teach AI assistants how to build production-ready n8n workflows using the n8n-mcp MCP server.
Why These Skills Exist
Building n8n workflows programmatically can be challenging. Common issues include:
- Using MCP tools incorrectly or inefficiently
- Getting stuck in validation error loops
- Not knowing which workflow patterns to use
- Misconfiguring nodes and their dependencies
These skills solve these problems by teaching Claude:
- ✅ Correct n8n expression syntax ({{}} patterns)
- ✅ How to use n8n-mcp tools effectively
- ✅ Proven workflow patterns from real-world usage
- ✅ Validation error interpretation and fixing
- ✅ Operation-aware node configuration
📚 The 5 Skills
1. n8n Expression Syntax
Teaches correct n8n expression syntax and common patterns.
Activates when: Writing expressions, using {{}} syntax, accessing $json/$node variables, troubleshooting expression errors.
Key Features:
- Core variables ($json, $node, $now, $env)
- Critical gotcha: Webhook data is under
$json.body - Common mistakes catalog with fixes
- When NOT to use expressions (Code nodes!)
2. n8n MCP Tools Expert (HIGHEST PRIORITY)
Expert guide for using n8n-mcp MCP tools effectively.
Activates when: Searching for nodes, validating configurations, accessing templates, managing workflows.
Key Features:
- Tool selection guide (which tool for which task)
- nodeType format differences (nodes-base.* vs n8n-nodes-base.*)
- Validation profiles (minimal/runtime/ai-friendly/strict)
- Smart parameters (branch="true" for IF nodes)
- Auto-sanitization system explained
Most Important: Teaches correct MCP tool usage patterns and parameter formats
3. n8n Workflow Patterns
Build workflows using 5 proven architectural patterns.
Activates when: Creating workflows, connecting nodes, designing automation.
Key Features:
- 5 proven patterns (webhook processing, HTTP API, database, AI, scheduled)
- Workflow creation checklist
- Real examples from 2,653+ n8n templates
- Connection best practices
- Pattern selection guide
4. n8n Validation Expert
Interpret validation errors and guide fixing.
Activates when: Validation fails, debugging workflow errors, handling false positives.
Key Features:
- Validation loop workflow
- Real error catalog
- Auto-sanitization behavior explained
- False positives guide
- Profile selection for different stages
5. n8n Node Configuration
Operation-aware node configuration guidance.
Activates when: Configuring nodes, understanding property dependencies, setting up AI workflows.
Key Features:
- Property dependency rules (e.g., sendBody → contentType)
- Operation-specific requirements
- AI connection types (8 types for AI Agent workflows)
- Common configuration patterns

💡 Usage
Skills activate automatically when relevant queries are detected:
"How do I write n8n expressions?"
→ Activates: n8n Expression Syntax
"Find me a Slack node"
→ Activates: n8n MCP Tools Expert
"Build a webhook workflow"
→ Activates: n8n Workflow Patterns
"Why is validation failing?"
→ Activates: n8n Validation Expert
"How do I configure the HTTP Request node?"

npm test
# Or manually test with Claude
claude-code --skill n8n-expression-syntax "Test webhook data access"
🤝 Contributing
Contributions welcome! Please see DEVELOPMENT.md for guidelines.
Development Approach
- Evaluation-First: Write test scenarios before implementation
- MCP-Informed: Test tools, document real responses
- Iterative: Test against evaluations, iterate until 100% pass
- Concise: Keep SKILL.md under 500 lines
- Real Examples: All examples from real templates/tools
