# Scenarios

> Scenario templates and composition for simulation scenarios

## Scenario Templates

Templates are named toolset combinations for common scenarios. Browse them with:

```bash theme={null}
simlab templates list
```

| Template             | Included Tools                                |
| -------------------- | --------------------------------------------- |
| `hr`                 | Frappe HRMS, Rocket.Chat, Email, Calendar     |
| `customer-service`   | Frappe Helpdesk, Rocket.Chat, Email, Calendar |
| `coding`             | OpenHands, Bash                               |
| `finance`            | SEC Edgar, Twelve Data, Google Workspace      |
| `personal-assistant` | OpenTable, Outlook, Weather, WhatsApp         |

Templates are a starting point; users can build custom combinations by selecting individual tools during `env init`.

## Scenario Composition

The composition engine takes your selected tools and produces a complete Docker Compose stack:

1. Collects services from each tool's YAML definition (main services, preseed services, seed services)
2. Adds networking — all services join a shared bridge network
3. Maps ports — only agent-facing and web UI ports get host bindings; internal services (databases, MCP servers) stay network-only
4. Detects port conflicts and auto-resolves them
5. Generates a `.env` file with placeholders for any required API keys
