## What it does

The skill takes the target design written by `direct` (`PRODUCT.md`, `DESIGN.md`, `DESIGN.json`, `stardust/direction.md`) and composes it onto page content captured by `extract` (`stardust/current/pages/<slug>.json`). Output lands at `stardust/prototypes/<slug>-proposed.html`. It does not draw the design itself: the creative work goes to `$impeccable craft`, and revisions run through `bolder`, `quieter`, `distill`, `polish`, `colorize`, `typeset`, `layout`, `adapt`, `animate`, `delight`, `overdrive`.

With no argument it prototypes every `directed` page that is not stale. `--all` includes stale ones, `--cinematic` writes a `<slug>-cinematic.html` next to the static file, and `--publish-sample <slug>` submits a page to the stardust showcase as a pull request. The `--prep` mode fills page-type gaps and writes canon back to `stardust/canon/`.

Setup is checked before anything renders. You need Node 22+, Playwright with Chromium resolvable from the project, `playwright-cli` on `PATH`, and the impeccable skill installed alongside. Playwright installs made with `--no-save` in earlier phases get pruned by any later real `npm i`, so the skill re-probes the `playwright` import and reinstalls on failure. There are no `--no-*` or `--skip-*` flags here: the quality gates are part of the process, and when a gate refuses a file you fix the file rather than lower the bar.

## Requirements
- Works with: Playwright

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add adobe/skills --skill prototype -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/prototype/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/prototype/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add adobe/skills --skill prototype -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/prototype/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add adobe/skills --skill prototype -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/prototype/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install adobe/skills prototype
```

2. **Manually: put the files in place**
- File: `.github/skills/prototype/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add adobe/skills --skill prototype -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/adobe/skills --path plugins/stardust/skills/prototype
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/prototype/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add adobe/skills --skill prototype -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/adobe/skills/tree/HEAD/plugins/stardust/skills/prototype/SKILL.md

## When to use it
- see how a page redesign looks before touching the code
- put the current page and the proposed one side by side
- build a page mockup and get it signed off in chat
- prototype one representative page per type while prepping a migration
- submit a finished prototype to the stardust showcase via pull request

## Example prompts
- /stardust:prototype home
- $stardust prototype --all
- $stardust prototype home --cinematic

# stardust:prototype

For each `directed` page, render a **proposed redesign** as a
self-contained static HTML file at
`stardust/prototypes/<slug>-proposed.html`. Open the file in the
browser; iterate via chat-driven impeccable commands ("make the
hero bolder", "tighten the cup-note grid"). Mark `approved` once
the user signs off in the conversation.

`prototype` is not a renderer of its own design — it composes the
target spec written by `direct` (`PRODUCT.md`, `DESIGN.md`,
`DESIGN.json`, `stardust/direction.md`) onto the page content captured
by `extract` (`stardust/current/pages/<slug>.json`). Visual creativity
is delegated to `$impeccable craft` and the iteration commands
(`bolder`, `quieter`, `distill`, `polish`, `colorize`, `typeset`,
`layout`, `adapt`, `animate`, `delight`, `overdrive`, `impeccable`).

## Inputs

- `<slug>` — optional positional. Prototype just this page. Without
  it, prototype every `directed` page that is not `stale`.
- `--all` — prototype every `directed` page including stale ones.
- `--prep` — optional. Run in **migrate-prep mode**: fill page-type
  gaps (prototype one representative archetype per type) and, on
  approval, write canon back to `stardust/canon/` and
  `DESIGN.json.extensions.canon`. See § Prep mode below and
  `reference/canon-extraction.md`. Typically invoked via the
  `prepare-migration` orchestrator.
- `--canon-from <slug>` — optional. Override the default canon-
  author (which is the first approved prototype, typically `home`).
  Used when a different page should establish the design canon.
- `--publish-sample <slug>` — submit the named slug to the
  stardust showcase. Triggers the publish-sample sub-flow
  documented in `reference/publish-sample.md`: eligibility checks,
  file staging, PR creation against the upstream stardust repo.
