+## 🚨 Critical Anti-Pattern Prevention
+
+### Most Common Wheels Errors
+1. **Mixed Arguments**: `hasMany("comments", dependent="delete")` ❌
+2. **Query vs Array Confusion**: `ArrayLen(posts)` on query objects ❌
+3. **Rails-style Routing**: Nested resource functions ❌
+4. **Non-existent Helpers**: `emailField()`, `passwordField()` ❌
+
+### Correct Patterns
+1. **Consistent Arguments**: `hasMany(name="comments", dependent="delete")` ✅
+2. **Query Methods**: `posts.recordCount` ✅
+3. **Separate Resources**: `.resources("posts").resources("comments")` ✅
+4. **Wheels Helpers**: `textField(type="email")` ✅
+
+## 🛠️ AI Assistant Implementation Guidelines
+
+### 🛑 MANDATORY Pre-Code Actions (NO EXCEPTIONS)
+1. **ALWAYS** read `.ai/wheels/troubleshooting/common-errors.md` FIRST
+2. **ALWAYS** read component-specific .ai documentation
+3. **VALIDATE** against anti-patterns before writing any code
+4. **REFERENCE** code examples from .ai documentation as templates
+5. **CHECK** implementation against validation templates continuously
+
+### Quality Assurance Process
+1. **Documentation First**: Always consult .ai documentation before coding
+2. **Pattern Consistency**: Follow established patterns from .ai documentation
+3. **Security Awareness**: Apply security practices from .ai documentation
+4. **Convention Adherence**: Follow Wheels naming and structure conventions
+5. **Validation**: Test implementations against documented standards
+
+## 🚀 Quick Reference Dispatchers
+
+### Component Quick Access
+- **Models**: `app/models/CLAUDE.md` → `.ai/wheels/models/`
+- **Controllers**: `app/controllers/CLAUDE.md` → `.ai/wheels/controllers/`
+- **Views**: `app/views/CLAUDE.md` → `.ai/wheels/views/`
+- **Configuration**: Root `CLAUDE.md` → `.ai/wheels/configuration/`
+
+### Critical Reading Priority
+1. **Error Prevention**: `.ai/wheels/troubleshooting/common-errors.md`
+2. **Data Handling**: Component-specific `data-handling.md` files
+3. **Best Practices**: Component-specific `best-practices.md` files
+4. **Architecture**: Component-specific `architecture.md` files
+
+## ✅ Post-Implementation Validation
+
+### MANDATORY Validation Commands
+```bash
+# 1. Syntax validation
+wheels server start --validate
+
+# 2. Test validation
+wheels test run
+
+# 3. Manual anti-pattern check
+# Check implementation against .ai documentation patterns
+```
+
+### If Validation Fails
+1. Consult `.ai/wheels/troubleshooting/common-errors.md`
+2. Review appropriate component documentation in `.ai/wheels/`
+3. Fix errors following documented patterns
+4. Re-run validation until all checks pass
+
+## 🎯 Success Criteria
+
+**Your implementation is successful when:**
+- [ ] All relevant .ai documentation has been read
+- [ ] No anti-patterns are present in the code
+- [ ] Patterns match those documented in .ai folder
+- [ ] Validation commands pass successfully
+- [ ] Code follows Wheels conventions and best practices
+
+🚨 **REMEMBER: The .ai folder contains the definitive, comprehensive documentation. ALWAYS use it as your primary reference!**

+# .ai Folder Contribution Summary
+
+## Overview
+
+This `.ai` folder contains comprehensive Wheels framework documentation extracted from real-world development sessions. The patterns, best practices, and solutions documented here are production-tested and ready for contribution to the Wheels project.
+
+## Generic Patterns Integrated (Ready for Wheels Project)
+
+### 🔴 Critical Patterns (High Impact for All Developers)
+
+#### 1. **Layout cfoutput Block Coverage** → [views/layouts.md](wheels/views/layouts.md)
+- **Issue**: Most common beginner error - CFML expressions not rendering
+- **Solution**: Single `<cfoutput>` block wrapping entire HTML layout
+- **Impact**: Affects 90%+ of new Wheels developers
+- **Location**: Enhanced in `common-errors.md` and `views/layouts.md`
+
+#### 2. **Form Helper Duplicate Labels** → [views/forms.md](wheels/views/forms.md)
+- **Issue**: Form helpers automatically generate labels, causing duplicates
+- **Solution**: Use `label=false` parameter when using custom HTML labels
+- **Impact**: Very common UX issue that confuses developers
+- **Location**: Documented in `views/forms.md` and `common-errors.md`
+
+#### 3. **Query vs Object Association Access** → [views/query-association-patterns.md](wheels/views/query-association-patterns.md) & [models/associations.md](wheels/models/associations.md)
+- **Issue**: Confusion between query objects and model instances in loops
+- **Solution**: Store association results in variables before looping
+- **Impact**: Fundamental misunderstanding causing frequent errors
+- **Location**: Comprehensive guide in `query-association-patterns.md`
+
+#### 4. **Consistent Argument Style Requirement** → [common-errors.md](wheels/troubleshooting/common-errors.md)
+- **Issue**: Mixed positional/named arguments cause cryptic errors
+- **Solution**: Always use all-named or all-positional arguments
+- **Impact**: Frequent error that's not obvious to fix
+- **Location**: Examples throughout all documentation files
+
+### 🗄️ Database & Migration Patterns
+
+#### 5. **Database-Agnostic Date Handling** → [database/migrations/date-function-issues.md](wheels/database/migrations/date-function-issues.md)
+- **Pattern**: Use CFML DateAdd/DateFormat instead of database-specific SQL
+- **Benefit**: Works across H2, MySQL, PostgreSQL, SQL Server
+- **Impact**: Portable migrations for all environments
+- **Location**: Comprehensive guide with examples
+
+#### 6. **Migration Direct SQL Best Practice** → [database/migrations/best-practices.md](wheels/database/migrations/best-practices.md)
+- **Pattern**: Direct SQL more reliable than parameter binding for data seeding
+- **Benefit**: Consistent migration execution across environments
+- **Impact**: Reduces migration failures
+- **Location**: New comprehensive best practices guide
+
+#### 7. **Working with Existing Schemas** → [database/migrations/best-practices.md](wheels/database/migrations/best-practices.md)
+- **Pattern**: Check for existing tables before creating migrations
+- **Solution**: Use `changeTable()` for additions to existing schema
+- **Impact**: Prevents "table already exists" errors
+- **Location**: New section in best-practices.md
+
+### 🧪 Testing Strategies
+
+#### 8. **Content Verification Over Status Codes** → [views/testing.md](wheels/views/testing.md)
+- **Issue**: HTTP 200 doesn't mean content rendered correctly
+- **Solution**: Verify actual content with grep/pattern matching
+- **Impact**: Catches rendering errors that status codes miss
+- **Location**: New critical section in testing.md
+
+#### 9. **Incremental Testing Approach** → [views/testing.md](wheels/views/testing.md)
+- **Pattern**: Test after each component (model → controller → view)
+- **Benefit**: Isolates issues quickly, prevents compound errors
+- **Impact**: Faster debugging and validation
+- **Location**: Command-line testing strategy in testing.md
+
+### 🎨 Modern Frontend Integration
+
+#### 10. **CDN-Based Frontend Stack** → [integration/modern-frontend-stack.md](wheels/integration/modern-frontend-stack.md)
+- **Pattern**: Tailwind CSS + Alpine.js + HTMX via CDN
+- **Benefit**: No build process, works seamlessly with CFML
+- **Impact**: Modern UI without complexity
+- **Location**: Complete integration guide with production examples
+
+### 🛣️ Routing & Configuration
+
+#### 11. **Route Configuration Order** → [configuration/routing.md](wheels/configuration/routing.md)
+- **Pattern**: Resources → Custom → Root → Wildcard
+- **Impact**: Prevents route matching conflicts
+- **Location**: Routing guide with examples
+
