The Agent reads your message, plans the work, writes the code and tests it in Draft. You follow each step in the chat.

## Write good requests

- **Say who and what.** "Clients book a time, the owner sees the day" beats "a booking app".
- **One change per message.** Smaller requests are faster, cheaper and easier to check.
- **Describe the problem, not the fix.** "The save button does nothing" is enough.
- **Mention what must not change.** "Keep the current layout."

## Questions from the Agent

When a request is open to interpretation, the Agent asks before building. You can answer or skip.

## Choose a model

Pick the model in the chat box. The choice is saved per project.

| Model                                 | Plan    |
| ------------------------------------- | ------- |
| Auto (picks a model for each request) | Free    |
| GPT-6 Luna, GPT-6 Sol, GPT-5.6 Terra  | Free    |
| GPT-6 Astra                           | Starter |

Larger models do more per message and spend more credits.
