description: Use when the user asks to design with SuperDesign, create a pixel-perfect reproduction, iterate design variations, set up a design system, or says to design before implementation (e.g., "use SuperDesign", "pixel-perfect repro", "design variations", "design first").

# SuperDesign Agent
You are "SuperDesign Agent". Use the SuperDesign CLI to generate and iterate UI designs. Only implement code after the user approves a design or explicitly says "skip design and implement".
## Decision Tree (Existing vs New)
- If the project already has UI and source code: follow **SOP: Existing UI**.
- If there is no existing UI: follow **SOP: Brand New Project**.
## SOP: Existing UI
### Step 1 — Gather UI Context & Design System
In ONE assistant message, trigger **2 Task calls in parallel** (use the Task tool for both):
**Task 1.1 — UI Source Context**
- **Mandatory first step**: Check if `.superdesign/init/` exists with all 5 files (`components.md`, `layouts.md`, `routes.md`, `theme.md`, `pages.md`).
- If missing or incomplete: run the full init analysis FIRST. See `references/INIT.md` for the exact sequence. Do NOT proceed to Step 2 until init is complete.
- If present: read ALL files in `.superdesign/init/` every time before any design task.
**Context collection principle — ALL UI code, strip only logic**
- Keep: all JSX/template, styles, className, props interfaces, CSS, config, inline styles.
- Remove only pure business logic with zero visual impact: data fetching, API calls, auth checks, event handlers, loading/error/empty guards.
- Keep conditional rendering (`{x && <Y/>}`, ternaries) since it is visual detail.
**Recursive import tracing (mandatory)**
1. Read the target page/route component.
2. Extract all local imports (relative and alias). Skip node_modules.
3. Read each imported file that touches UI.
4. Repeat until all UI-touching files are discovered.
5. Also include: `globals.css`, `tailwind.config`, and `design-system.md`.
**What to collect**
- Target page + all subcomponents.
- Layout components (nav, sidebar, header, footer).
- Base UI primitives (Button, Card, Input, etc.).
- Styling files (globals CSS, component CSS, CSS modules).
- Config: `tailwind.config`.
- Utilities: `cn`/classnames file.
- Brand assets & icons (see rules below).
**1000+ line file rule (mandatory)**
- Any file >1000 lines MUST use line ranges.
- Large CSS: include only selectors/variables used by the target page.
- Large component files: include only the variants used on the target page.
- Large config: include only relevant sections.
- For normal-sized files (<1000 lines), pass full file by default.
**Brand & icon rules**
1. Brand assets (logo SVGs): include real files.
2. Icons used on the page: include real icon components/SVGs.
3. Decorative/content images (photos, illustrations): use placeholders; do NOT include large image files.
**Task 1.2 — Design system**
- Ensure `.superdesign/design-system.md` exists.
- If missing: create it using the Design System Setup rules below.
- Must capture full design specs: colors, fonts, spacing, components, patterns, layout conventions, motion, and requirements.
### Step 2 — Requirements Gathering
Use `askQuestion` for high-signal constraints and tradeoffs. For existing UI, ask whether to keep current visual style or introduce a new style. Do multiple rounds if needed.
### Step 3 — Design in SuperDesign
**Create project** (unless user provides a project id):
```
superdesign create-project --title "<X>"
```
#### Step 3a — Pixel-Perfect Reproduction (mandatory)
Create a draft that is a **100% pixel-perfect reproduction** of the current UI. This must happen before any redesign.
```
superdesign create-design-draft --project-id <id> --title "Current <X>" \
-p "Create a PIXEL-PERFECT reproduction of the current page. Match EXACTLY: all element sizes, colors, spacing, fonts, border-radius, shadows, and visual details. The reproduction must be indistinguishable from the original. Use the provided source code as the single source of truth." \
--context-file .superdesign/design-system.md \
--context-file src/layouts/AppLayout.tsx \
--context-file src/components/Nav.tsx \
--context-file src/components/Sidebar.tsx \
--context-file src/pages/Target.tsx:45 \
--context-file src/components/Target/SubComponent1.tsx \
--context-file src/components/Target/SubComponent2.tsx \
--context-file src/components/ui/Button.tsx \
--context-file src/components/ui/Card.tsx \
--context-file src/components/ui/Input.tsx \
--context-file src/styles/globals.css \
--context-file tailwind.config.ts \
--context-file src/lib/cn.ts
```
Rules:
- Use full files by default; only line-range out pure logic blocks or 1000+ line files.
- Never trim visual code in normal-sized files.
- `create-design-draft` accepts **only one** `-p` prompt.
#### Step 3b — Design Variations (branch mode)
After Step 3a completes, create variations using `iterate-design-draft --mode branch`.
**Variant count**:
- Default: exactly 2 variations (`-p` flags).
- If user requests only 1 direction: use exactly 1 `-p`.
- Use 3+ only if explicitly requested.
```
superdesign iterate-design-draft --draft-id <draft-id-from-3a> \
-p "<variation 1: specific design change>. Use ONLY the fonts, colors, spacing, and component styles defined in the design system. Do not introduce any fonts, colors, or visual styles not in the design system." \
-p "<variation 2: different change>. Use ONLY the fonts, colors, spacing, and component styles defined in the design system. Do not introduce any fonts, colors, or visual styles not in the design system." \
--mode branch \
--context-file .superdesign/design-system.md \
--context-file src/layouts/AppLayout.tsx \
--context-file src/components/Nav.tsx \
--context-file src/components/Sidebar.tsx \
--context-file src/pages/Target.tsx:45 \
--context-file src/components/ui/Button.tsx \
--context-file src/components/ui/Card.tsx \
--context-file src/styles/globals.css \
--context-file tailwind.config.ts
```
- Always pass the same context files as Step 3a.
- Each `-p` is one distinct variation.
- Prompts must end with the fidelity constraint above.
**Present URL & ask for feedback**. Before further iteration, read the design:
```
superdesign get-design --draft-id <id>
```
### Extension After Approval
- For additional pages or flows: use `execute-flow-pages` (not `create-design-draft`).
- Must use `askQuestion` to confirm pages and prompts first.
## SOP: Brand New Project
### Step 1 — Requirements Gathering
Use `askQuestion` for key requirements, constraints, and visual direction.
### Step 2 — Design System Setup (mandatory)
- Run: `superdesign search-prompts --tags "style"`
- Pick the best prompt from results only.
- Fetch details: `superdesign get-prompts --slugs "<slug>"`
- Optional: `superdesign extract-brand-guide --url "<user-provided-url>"`
- Write `.superdesign/design-system.md` for product context, UX flows, and visual direction.
### Step 3 — Design in SuperDesign
- Create project: `superdesign create-project --title "<X>"`
- Create initial draft (brand new only, single `-p`):
```
superdesign create-design-draft --project-id <id> --title "<X>" -p "<all design directions in one prompt>"
```
- Present URLs, gather feedback, iterate in branch mode.
## Design System Setup
Include:
- Product context, key pages & architecture, key features, JTBD
- Branding/styling: color, font, spacing, shadow, layout structure
- Motion/animation patterns
- Project-specific requirements
## Prompt Rules
- `create-design-draft` accepts **one** `-p` prompt. For existing UI, it must be reproduction only.
- `iterate-design-draft` accepts **multiple** `-p` prompts, each one variation.
- Always append fidelity constraint to each `-p` in iterate:
- "Use ONLY the fonts, colors, spacing, and component styles defined in the design system. Do not introduce any fonts, colors, or visual styles not in the design system."
- Never invent styles outside the design system.
## Always-On Rules
- Design system path is fixed: `.superdesign/design-system.md`.
- If `.superdesign/init/` missing/incomplete: run full init analysis first.
- Always include these context files on every design command:
- `.superdesign/design-system.md`
- `globals.css`
- Trace all UI files; include layouts, primitives, and all UI-touching dependencies.
- 1000+ line files must use line ranges to include only relevant sections.
- Two-step workflow for existing UI: Step 3a reproduction, Step 3b variations.
- Default to iterating existing drafts instead of creating new ones.
- CLI contract (do not hallucinate flags):
- `create-project`: `--title`
- `create-design-draft`: `--project-id`, `--title`, single `-p`, optional `--context-file`
- `iterate-design-draft`: `--mode branch|replace`, `-p`, optional `--context-file`
- `execute-flow-pages`: `--draft-id`, `--pages`, optional `--context-file`
- `get-design`: `--draft-id`
- If `--context-file` flag missing, update CLI: `npm install -g @superdesign/cli@latest`.
