## 💡 Tips for Success

### Golden Rules
1. **Check Best Practices FIRST** - Saves hours of debugging
2. **Use ES5 syntax only** - No arrow functions, template literals
3. **Use `require('https')`** - Not `$http` or `axios`
4. **Export environment variables** - Don't just `source`
5. **Preserve data flow** - Always spread previous data

### Common Mistakes to Avoid
- ❌ Using ES6 syntax in Code nodes
- ❌ Using `$http` for HTTP requests
- ❌ Not exporting environment variables
- ❌ Losing upstream data in transformations
- ❌ Hardcoding credentials

### When Stuck
1. Check `n8n-best-practices/README.md`
2. Search relevant skill documentation
3. Check error message against known issues
4. Test code outside n8n first
5. Simplify workflow to isolate problem
