# CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

## Project Overview

Quantum Tasks AI is a Django-based AI agent marketplace platform. Users can access AI agent services through a web interface, with execution handled via two distinct systems: N8N webhook integrations and direct form access integrations.

**Key Architecture:**
- **Django Framework**: Main web application using Django 5.2.4
- **Agent System**: Database-driven agents app with dual integration systems:
  - **Webhook Agents**: N8N integrations for complex processing
  - **Direct Access Agents**: Form-based integrations (JotForm, etc.)
- **Authentication**: Custom user model with email verification
- **Payments**: Stripe integration with wallet system (supports free agents)
- **Database**: SQLite for development, PostgreSQL for production (Railway)
- **Static Files**: WhiteNoise for production static file serving

## Core Architecture

### Apps Structure
- **authentication/**: Custom user model, email verification, password reset
- **core/**: Homepage, error handlers, utility functions
- **agents/**: Database-driven agent system (marketplace, execution, models, REST API)
- **wallet/**: Stripe payments, wallet management, transactions

### Agent System (agents app)
**Key Files:**
- `agents/models.py`: Agent, AgentCategory, AgentExecution, ChatSession models
- `agents/views.py`: Dual integration systems and web interface views
- `agents/templates/agents/`: Dynamic agent templates and marketplace
- `agents/management/commands/`: Agent creation and management commands
- `templates/career_navigator.html`: Direct access form template

**Dual Integration Systems:**

**System 1: Webhook Agents (N8N Integration)**
1. User browses marketplace (`/agents/`)
2. Clicks "Try Now" → Agent detail page (`/agents/{slug}/`)
3. Fills dynamic form → Form submission calls `/agents/api/execute/`
4. N8N webhook processes request and returns response
5. Results displayed with file upload support

**System 2: Direct Access Agents (Form Integration)**
1. User browses marketplace (`/agents/`)
2. Clicks special "Try Now" button → Direct access (`/agents/{slug}/access/`)
3. Payment processed → Redirect to form page (`/agents/{slug}/`)
4. Form displays embedded interface (JotForm, etc.)
5. User interacts directly with external form system

### Database Models
**User Management:**
- `authentication.User`: Custom user model with email verification
- `authentication.PasswordResetToken`: Password reset tokens
- `authentication.EmailVerificationToken`: Email verification tokens

**Agents:**
- `agents.Agent`: Agent definitions with JSON form schemas and pricing
- `agents.AgentCategory`: Agent categories with icons and descriptions
- `agents.AgentExecution`: Execution history and results tracking

**Payments:**
- `wallet.Wallet`: User wallet with balance tracking
- `wallet.WalletTransaction`: Transaction history and Stripe integration

### Settings Configuration
**Environment Variables (Required for Production):**
- `SECRET_KEY`: Django secret key
- `ALLOWED_HOSTS`: Comma-separated list of allowed hosts
- `EMAIL_HOST_USER`, `EMAIL_HOST_PASSWORD`: SMTP credentials
- `STRIPE_SECRET_KEY`, `STRIPE_WEBHOOK_SECRET`: Stripe API keys
- `DATABASE_URL`: PostgreSQL connection string (Railway)

### URL Structure
```
/                       # Homepage (core app)
/digital-branding/      # Digital branding services page
/auth/                  # Authentication (login, register, etc.)
/agents/                # Agent marketplace (agents app)
/agents/{slug}/         # Individual agent pages (webhook agents)
/agents/career-navigator/       # Career navigator form page
/agents/career-navigator/access/ # Career navigator payment processing
/agents/ai-brand-strategist/    # AI Brand Strategist form page
/agents/ai-brand-strategist/access/ # AI Brand Strategist payment processing
/wallet/                # Wallet management
/admin/                 # Django admin
```

### Key Components
**Agent Configuration (Database-driven):**
- All agent metadata stored in database (pricing, descriptions, webhooks)
- JSON form schemas for dynamic form generation
- Easy to add new agents via management commands or admin interface

**Templates:**
- `templates/base.html`: Main layout with navigation
- `templates/components/`: Reusable UI components
- `agents/templates/agents/`: Dynamic agent forms and marketplace pages

## Adding New Agents

**CRITICAL**: The platform has **TWO DISTINCT AGENT SYSTEMS**. Choose the correct system based on your requirements.

### **System 1: Webhook Agents (N8N Integration)**

**Use for:** Dynamic forms, server-side processing, file uploads, complex workflows
**Examples:** Social Ads Generator, PDF Summarizer, Job Posting Generator

**Flow:** Marketplace → Agent detail page → Dynamic form → N8N webhook → Results

**Implementation Steps:**
1. **Create management command** (e.g., `create_content_optimizer.py`):
```python
from django.core.management.base import BaseCommand
from agents.models import AgentCategory, Agent

class Command(BaseCommand):
    def handle(self, *args, **options):
        category, _ = AgentCategory.objects.get_or_create(
            slug='content-tools',
            defaults={'name': 'Content Tools', 'icon': '📝'}
        )
        
        Agent.objects.get_or_create(
            slug='content-optimizer',
            defaults={
                'name': 'Content Optimizer',
                'short_description': 'AI-powered content optimization',
                'description': 'Enhance your content for better engagement',
                'category': category,
                'price': 5.0,
                'agent_type': 'form',
                'form_schema': {
                    'fields': [
                        {
                            'name': 'content',
                            'type': 'textarea',
                            'label': 'Content to Optimize',
                            'required': True
                        },
                        {
                            'name': 'content_type',
                            'type': 'select',
                            'label': 'Content Type',
                            'required': True,
                            'options': [
                                {'value': 'blog', 'label': 'Blog Post'},
                                {'value': 'social', 'label': 'Social Media'}
                            ]
                        }
                    ]
                },
                'webhook_url': 'http://localhost:5678/webhook/content-optimizer',
                'access_url_name': '',  # Empty for webhook agents
                'display_url_name': ''  # Empty for webhook agents
            }
        )
```

2. **Run command**: `python manage.py create_content_optimizer`
3. **Create N8N workflow** at the webhook URL
4. **Agent automatically appears** in marketplace with dynamic form

### **System 2: Direct Access Agents (Embedded External Forms)**

**Use for:** External form services (JotForm, Google Forms), consultation interfaces, embedded tools
**Examples:** CyberSec Career Navigator, AI Brand Strategist

**Flow:** Marketplace → Payment processing → Quantum Tasks header + embedded external form

**Implementation Steps:**
1. **Create management command** (e.g., `create_business_consultant.py`):
```python
from django.core.management.base import BaseCommand
from agents.models import AgentCategory, Agent

class Command(BaseCommand):
    def handle(self, *args, **options):
        category, _ = AgentCategory.objects.get_or_create(
            slug='consulting',
            defaults={'name': 'Business Consulting', 'icon': '💼'}
        )
        
        Agent.objects.get_or_create(
            slug='business-consultant',
            defaults={
                'name': 'Business Consultant',
                'short_description': 'Expert business consultation',
                'description': 'Get professional business advice and strategy',
                'category': category,
                'price': 0.0,
                'agent_type': 'form',
                'form_schema': {'fields': []},  # Empty - using external form
                'webhook_url': 'https://form.jotform.com/your-form-id',
                'access_url_name': 'agents:direct_access_handler',
                'display_url_name': 'agents:direct_access_display'
            }
        )
```

2. **Create dedicated template** (`templates/business_consultant.html`):
```html
{% extends 'base.html' %}
{% load static %}

{% block title %}Business Consultant - Quantum Tasks AI{% endblock %}

{% block extra_css %}
<style>
.main-container {
    max-width: none;
    padding: 0;
    height: calc(100vh - 80px);
}
.iframe-container {
    width: 100%;
    height: 100%;
}
.iframe-container iframe {
    width: 100%;
    height: 100%;
    border: none;
    display: block;
}
.footer {
    display: none !important;
}
</style>
{% endblock %}

{% block content %}
<div class="iframe-container">
    <iframe 
        src="{{ form_url }}"
        frameborder="0"
        scrolling="auto"
        title="Business Consultant">
    </iframe>
</div>
{% endblock %}
```

3. **Add dedicated view functions** (in `agents/views.py`):
```python
def business_consultant_view(request):
    """Display the Business Consultant form page"""
    if not request.user.is_authenticated:
        storage = messages.get_messages(request)
        storage.used = True
        messages.error(request, 'Please login to access the Business Consultant.')
        return redirect('authentication:login')
    
    try:
        agent = Agent.objects.get(slug='business-consultant', is_active=True)
    except Agent.DoesNotExist:
        messages.error(request, 'Business Consultant is currently unavailable.')
        return redirect('agents:marketplace')
    
    from django.utils import timezone
    from datetime import timedelta
    
    recent_execution = AgentExecution.objects.filter(
        agent=agent,
        user=request.user,
        status='completed',
        created_at__gte=timezone.now() - timedelta(hours=2)
    ).first()
    
    if not recent_execution:
        messages.info(request, 'Please click "Try Now" to access your Business Consultant.')
        return redirect('agents:marketplace')
    
    context = {
        'agent': agent,
        'form_url': agent.webhook_url,
        'user_balance': request.user.wallet_balance,
        'execution': recent_execution
    }
    
    return render(request, 'business_consultant.html', context)

def business_consultant_access(request):
    """Handle Try Now button click - charge wallet and redirect to form"""
    if not request.user.is_authenticated:
        storage = messages.get_messages(request)
        storage.used = True
        messages.error(request, 'Please login to access the Business Consultant.')
        return redirect('authentication:login')
    
    try:
        agent = Agent.objects.get(slug='business-consultant', is_active=True)
    except Agent.DoesNotExist:
        messages.error(request, 'Business Consultant is currently unavailable.')
        return redirect('agents:marketplace')
    
    if not request.user.has_sufficient_balance(agent.price):
        messages.error(request, f'Insufficient balance! You need {agent.price} AED.')
        return redirect('wallet:wallet')
    
    success = request.user.deduct_balance(
        agent.price, 
        f'{agent.name} - Direct Access',
        agent.slug
    )
    
    if not success:
        messages.error(request, 'Failed to process payment. Please try again.')
        return redirect('agents:marketplace')
    
    AgentExecution.objects.create(
        agent=agent,
        user=request.user,
        input_data={'action': 'direct_access', 'source': 'try_now_button'},
        fee_charged=agent.price,
        status='completed',
        output_data={
            'type': 'direct_access',
            'message': f'Direct access granted to {agent.name}',
            'access_method': 'try_now_button'
        },
        completed_at=timezone.now()
    )
    
    messages.success(request, f'Welcome to your {agent.name} consultation.')
    return redirect('agents:business_consultant')
```

4. **Add URL routes** (in `agents/urls.py`):
```python
# Add to direct access routes section
path('business-consultant/', views.business_consultant_view, name='business_consultant'),
path('business-consultant/access/', views.business_consultant_access, name='business_consultant_access'),
```

5. **Update marketplace template** (in `agents/templates/agents/marketplace.html`):
```html
# Add to marketplace button logic
{% elif agent.slug == 'business-consultant' %}
    <a href="{% url 'agents:business_consultant_access' %}" class="try-btn">
        💼 Try Now → 
    </a>
```

6. **Run command**: `python manage.py create_business_consultant`
7. **Create external form** (JotForm, Google Forms, etc.)
8. **Agent appears** in marketplace with embedded form interface

### **Key Differences Summary:**

| Aspect | Webhook Agents | Direct Access Agents |
|--------|----------------|---------------------|
| **Form Processing** | Server-side (Django + N8N) | External service (JotForm) |
| **Form Display** | Dynamic Django forms | Embedded external forms |
| **Results** | Displayed in Quantum Tasks | Handled by external service |
| **Templates** | Uses generic `agent_detail.html` | Requires dedicated template |
| **View Functions** | Uses generic `agent_detail_view` | Requires dedicated view functions |
| **URL Routes** | Uses generic `/{slug}/` | Requires dedicated routes |
| **Marketplace Integration** | Automatic | Requires template updates |

### **Supported Form Field Types (Webhook Agents Only):**
- `text`: Single-line text input
- `textarea`: Multi-line text input
- `select`: Dropdown with options array
- `file`: File upload with drag-and-drop
- `url`: URL input with validation
- `checkbox`: Boolean checkbox

### **Common Mistakes to Avoid:**
1. **Don't mix systems** - webhook agents should have empty `access_url_name` fields
2. **Don't forget marketplace updates** - direct access agents need template updates
3. **Don't skip dedicated templates** - direct access agents need their own HTML files
4. **Don't use generic routes** - direct access agents need dedicated URL patterns

## Production Deployment

**Railway Configuration:**
- Automatic deployment from git repository
- PostgreSQL database provided by Railway
- Environment variables configured in Railway dashboard
- Static files served via WhiteNoise

**Security Features:**
- CSRF protection enabled
- Rate limiting on sensitive endpoints
- Secure headers in production
- HTTPS redirect and HSTS headers
- Session and cookie security

## Development Notes

- **Database**: Uses SQLite by default for development reliability
- **Cache**: Redis preferred, falls back to local memory cache
- **Email**: Console backend in development, SMTP in production
- **Debug Tools**: Debug toolbar and Django extensions available in development
- **Static Files**: Collected to `staticfiles/` directory for production
- **Media Files**: User uploads stored in `media/` directory

## Common Development Tasks

**Adding new environment variables:**
1. Add to `settings.py` with `config()` call
2. Add to required_env_vars list if production-required
3. Document in this file

**Database changes:**
1. Make model changes
2. Run `python manage.py makemigrations`
3. Review migration file
4. Run `python manage.py migrate`

**Testing agent webhooks locally:**
1. Use ngrok or similar to expose local server
2. Update webhook URLs in agent database records
3. Test agent execution flow
4. Check AgentExecution records and results display

## System Status

**Current Status: ✅ STABLE COMPREHENSIVE SYSTEM**
- **6 agents** confirmed working and tested (4 webhook + 2 direct access)
- **Dual integration architecture** with clear separation and documentation
- **Embedded form interfaces** with Quantum Tasks headers working correctly
- **Chat-based and form-based** agent systems operational
- **Scalable architecture** ready for 100+ agents

**Current Agents:**
- **Webhook Agents (4)**: Social Ads Generator, Job Posting Generator, PDF Summarizer, 5 Whys Analyzer
- **Direct Access Agents (2)**: CyberSec Career Navigator, AI Brand Strategist

**Latest Changes:**
- **Added AI Brand Strategist** with embedded JotForm interface and Quantum Tasks header
- **Documented complete agent creation process** with clear system distinctions
- **Established patterns** for both webhook and direct access agent development
- **Fixed architecture inconsistencies** between different agent types
- **Updated comprehensive documentation** to prevent future agent creation issues

**Architecture Clarity:**
- **Two distinct systems** clearly documented with implementation examples
- **Common mistakes** section added to prevent development issues
- **Step-by-step guides** for both agent types with complete code examples
- **Key differences table** for quick reference during development

**Future Development:**
- **New agents** should follow documented patterns in "Adding New Agents" section
- **Direct access agents** require dedicated templates, views, and URL routes
- **Webhook agents** use generic dynamic form generation system
- **No more architecture confusion** - clear documentation prevents implementation issues
