+## Agent Creation Checklist
+
+Use this checklist to ensure proper component architecture and avoid legacy contamination:
+
+### ✅ Pre-Development Checklist
+- [ ] Read Template Component Architecture section above
+- [ ] Review `agent_template_prototype.html` for UI patterns
+- [ ] Understand WorkflowsCore utilities available
+- [ ] **Never** open existing agent templates for reference
+
+### ✅ Development Checklist
+- [ ] Start with `agent-template-starter.html` as base
+- [ ] Use required component includes:
+  - [ ] `{% include "workflows/components/agent_header.html" %}`
+  - [ ] `{% include "workflows/components/quick_agents_panel.html" %}`
+  - [ ] `{% include "workflows/components/processing_status.html" %}`
+  - [ ] `{% include "workflows/components/results_container.html" %}`
+- [ ] Link to shared CSS: `{% static 'css/agent-base.css' %}`
+- [ ] Link to WorkflowsCore: `{% static 'js/workflows-core.js' %}`
+- [ ] Write only agent-specific form fields (50-100 lines max)
+- [ ] Use WorkflowsCore utilities instead of custom JavaScript
+
+### ✅ Quality Assurance Checklist
+- [ ] Template under 500 lines total
+- [ ] Inline JavaScript under 100 lines
+- [ ] Agent-specific CSS under 200 lines
+- [ ] No duplicate utility functions
+- [ ] All shared functionality uses components
+- [ ] Copy/download/reset buttons work automatically
+
+### ❌ Red Flags (Reject if Present)
+- [ ] Template over 500 lines
+- [ ] Custom `copyResults()` function
+- [ ] Custom `downloadResults()` function  
+- [ ] Custom `showToast()` implementation
+- [ ] Inline agent header HTML
+- [ ] Inline quick agents panel HTML
+- [ ] Duplicate CSS from agent-base.css
+
+### 📋 Review Questions
+1. Does this template follow the component architecture?
+2. Could this code be maintained by someone else easily?
+3. Would adding a new shared feature require updating this template?
+4. Does this template look similar to other agent templates?
+
+**If any answer is "No", refactor using component architecture.**
+
 ### Template Component Architecture
 
 **CRITICAL: Always Use Component-Based Architecture**
 
 All agent templates MUST use the established component system. Never recreate shared functionality inline.
 
+**⚠️ WARNING: Avoid Legacy System Contamination**
+
+When creating new agents, NEVER use existing legacy agent templates as reference. This leads to:
+- ❌ 1,000+ line templates instead of clean 300-line templates
+- ❌ Duplicate JavaScript instead of WorkflowsCore utilities
+- ❌ Inline CSS instead of shared component styles
+- ❌ Technical debt imported into clean architecture
+
+**✅ CORRECT Process for New Agents:**
+1. Start with `agent_template_prototype.html` for UI patterns
+2. Use Template Component Architecture components
+3. Add only agent-specific form fields
+4. Leverage WorkflowsCore for all utilities
+5. Result: Clean, maintainable templates
+
+**❌ INCORRECT Process (Legacy Contamination):**
+1. Copy from existing working agent template
+2. Modify inline code for new functionality
+3. Result: Bloated, unmaintainable templates

+# Legacy Agent Migration Guide
+
+## Overview
+
+This guide explains how to properly convert legacy agent templates to the new Template Component Architecture without introducing technical debt or code bloat.
+
+## ⚠️ The Legacy Contamination Problem
+
+When converting legacy agents, the natural instinct is to copy existing working code. However, this leads to:
+
+- **Template Bloat**: 1,000+ line templates instead of 300 lines
+- **Duplicate Code**: Custom implementations instead of shared utilities
+- **Maintenance Issues**: Multiple copies of the same functionality
+- **Architecture Violations**: Inline code instead of component system
+
+## ✅ Correct Migration Process
+
+### Step 1: Analyze Legacy Functionality (Don't Copy Code!)
+
+**DO**: List the functional requirements
+```
+- File upload for PDF files
+- Radio button selection for analysis type
+- Display analysis results with formatting
+- Copy, download, reset functionality
+```
+
+**DON'T**: Copy the implementation code
+```
+❌ Never copy 500+ lines of inline JavaScript
+❌ Never copy 400+ lines of custom CSS
+❌ Never copy custom implementations of shared utilities
+```
+
+### Step 2: Map to Component Architecture
+
+**Legacy Approach (Wrong)**:
+```django
+<!-- 100+ lines of custom header HTML -->
+<!-- 200+ lines of custom form HTML -->
+<!-- 300+ lines of custom JavaScript -->
+<!-- 400+ lines of custom CSS -->
+```
+
+**Component Approach (Right)**:
+```django
+{% include "workflows/components/agent_header.html" %}
+{% include "workflows/components/quick_agents_panel.html" %}
+<!-- 50 lines of agent-specific form -->
+{% include "workflows/components/processing_status.html" %}
+{% include "workflows/components/results_container.html" %}
+```
+
+### Step 3: Use Agent Template Prototype as Reference
+
+**Start with**: `agent_template_prototype.html` (perfect UI patterns)
+**Not with**: Existing legacy agent template
+
+The prototype shows exactly how components should work together.
+
+### Step 4: Implement Only Agent-Specific Logic
+
+**Keep from Legacy**:
+- ✅ Business logic requirements
+- ✅ Form field definitions
+- ✅ Validation rules
+- ✅ API integration patterns
+
+**Replace with Components**:
+- ❌ Header implementation → Use `agent_header.html`
+- ❌ Navigation panel → Use `quick_agents_panel.html`
+- ❌ Processing display → Use `processing_status.html`
+- ❌ Results display → Use `results_container.html`
+- ❌ Utility functions → Use `WorkflowsCore`
+
+## 📊 Migration Results Comparison
+
+| Aspect | Legacy Approach | Component Approach | Improvement |
+|--------|----------------|-------------------|-------------|
+| **Template Size** | 1,031 lines | 285 lines | 72% reduction |
+| **CSS Lines** | 480+ lines | 145 lines | 70% reduction |
+| **JavaScript** | 500+ inline | 150 external | 70% reduction |
+| **Maintenance** | Individual updates | Shared component updates | Automatic |
+| **Consistency** | Varies per agent | Identical across agents | Perfect |
+
+## 🎯 Real Example: Data Analyzer Migration
+
+### Before (Legacy Contamination)
+```django
+<!-- data_analyzer/templates/data_analyzer/detail.html - 928 lines -->
+<script>
+// 500+ lines of custom JavaScript duplicating WorkflowsCore
+function copyResults() {
+    // Custom implementation
+}
+function downloadResults() {
+    // Custom implementation  
+}
+// ... hundreds more lines
+</script>
+
+<style>
+/* 400+ lines of custom CSS duplicating agent-base.css */
+.file-upload-area { /* custom styles */ }
+.radio-card { /* custom styles */ }
+/* ... hundreds more lines */
+</style>
+```
+
+### After (Component Architecture)
+```django
+<!-- workflows/templates/workflows/data-analyzer.html - 285 lines -->
+{% include "workflows/components/agent_header.html" %}
+{% include "workflows/components/quick_agents_panel.html" %}
+
+<!-- 50 lines of agent-specific form -->
+<div class="form-group">
+    <label>📁 Upload Data File</label>
+    <input type="file" name="file" accept=".pdf">
+</div>
+
+{% include "workflows/components/processing_status.html" %}
+{% include "workflows/components/results_container.html" %}
+```
+
+**Result**: 72% smaller, consistent UI, automatic utility functions.
+
+## 🛡️ Prevention Guidelines
+
+### For Developers
+1. **Never start migration by reading legacy template code**
+2. **Always start with `agent_template_prototype.html` for UI reference**
+3. **Use component includes for all shared functionality**
+4. **Write only agent-specific form fields and validation**
+
+### For Code Reviews
+1. **Reject any template over 500 lines**
+2. **Reject any inline JavaScript over 100 lines**
+3. **Reject any custom CSS over 200 lines**
+4. **Require component include usage**
+
+### Red Flags in Pull Requests
+- ❌ `function copyResults()` - Should use `WorkflowsCore.copyResults()`
+- ❌ `function downloadResults()` - Should use `WorkflowsCore.downloadResults()`
+- ❌ Custom toast implementations - Should use `WorkflowsCore.showToast()`
+- ❌ Custom processing displays - Should use `processing_status.html` component
+- ❌ Custom header implementations - Should use `agent_header.html` component

+
+## 🎯 Key Takeaway
+
+**Legacy functionality should inspire new components, not contaminate them.** 
+
+The goal is to preserve the user experience and business logic while completely replacing the implementation with clean, maintainable component architecture.
