Installation options and first steps →
Describe the outcome in your agent chat. You don’t need to know a special command.
Start with an idea, a new page, or a redesign. Choose a direction, then bring it into code.
Describe what feels wrong or ask for a focused pass. Keep the decisions that already work.
Mockup first (comp-led) opens up bolder visual directions, with several rounds to translate the image into code. Build directly (code-led) tends to produce a more coherent first build, with less ambitious visuals.
Enable image generation with your coding tool or an OpenAI API key. Compare the workflows →
Use a focused command when you know what kind of change you want.
