# 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)

**Current Agents:**

- 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

1. **Create management command** (recommended approach):
```python
# agents/management/commands/create_new_agent.py
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='category-slug',
            defaults={'name': 'Category Name', 'icon': '🤖'}
        )
        
        Agent.objects.get_or_create(
            slug='agent-slug',
            defaults={
                'name': 'Agent Name',
                'short_description': 'Brief description',
                'description': 'Full description',
                'category': category,
                'price': 10.0,
                'form_schema': {
                    'fields': [
                        {
                            'name': 'input_field',
                            'type': 'text',
                            'label': 'Input Field',
                            'required': True
                        }
                    ]
                },
                'webhook_url': 'http://your-n8n-webhook-url'
            }
        )
```

2. **Run the command**: `python manage.py create_new_agent`
3. **Update N8N workflow** to handle the new agent
4. **Agent will automatically appear** in marketplace with dynamic form generation

**Supported Form Field Types:**
- `text`: Text input
- `textarea`: Multi-line text
- `select`: Dropdown with options
- `file`: File upload with drag-and-drop
- `url`: URL input with validation
- `checkbox`: Boolean checkbox

## 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
