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. All distribution packages regenerated with cleaned documentation. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> Conceived by Romuald Członkowski - https://www.aiadvisors.pl/en

## 🎯 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](https://github.com/czlonkowski/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
|
|

## 🤝 Contributing
|
|
|
|
Contributions welcome! Please see [DEVELOPMENT.md](docs/DEVELOPMENT.md) for guidelines.
|
|
|
|
### Development Approach
|
|
|
|
1. **Evaluation-First**: Write test scenarios before implementation
|
|
2. **MCP-Informed**: Test tools, document real responses
|
|
3. **Iterative**: Test against evaluations, iterate until 100% pass
|
|
4. **Concise**: Keep SKILL.md under 500 lines
|
|
5. **Real Examples**: All examples from real templates/tools
