# Cloud Design Prototyping

Prototype UIs with AI via Cloud Design (`/design`) or local-first Open Design. Detalhes em `references/`.

## When to Activate

- User wants to prototype a site/app with AI
- Using the Cloud Code `/design` command with interactive canvas
- Locking visual direction (5 curated options or brand extraction)
- Dual editing: manual clicks + prompts in the same canvas
- Mobile/desktop preview in the same flow
- Exporting to HTML/CSS, PPTX, PDF, or MP4 for engineering handoff

## Core Flow

1. **Brief** — natural-language brief or built-in template
2. **Direction** — lock visual direction (5 options or Figma/screenshot extract)
3. **Design** — plugin + skill + `DESIGN.md` tokens → canonical files
4. **Artifact** — real HTML/CSS preview with dual edit + dual preview
5. **Handoff** — export and continue as real code in Cursor/Codex/Code

## Design-system-first (Batch 17c, #61)

One-shot prompts produce generic output (padaria site = pizzaria site).
Teach the pattern BEFORE generating: a design system (button, type,
spacing, radius as tokens) is what separates generic from distinctive.
Cloud Design 2.0 also fixed the brutal token burn of v1 — but direction
lock (step 2) is still what saves cost: no system, no identity, more
iterations burned.

## Example

```bash
# New project from brief, then export for engineering
open-design new --brief "Landing page para produto SaaS"
open-design export --format html --output ./handoff
```
