## What it does

The skill turns web page redesigns into a repeatable pipeline. It takes a local HTML file or a live dev server URL, takes a 1920×1200 screenshot via Puppeteer, and prompts an Opus 4.7 vision model to write an image transformation query. The `fal-ai/gpt-image-2/edit` model renders `after.png`, while Opus produces `tokens.json` alongside a `changes.md` build specification with strict layout constraints.

Under the hood sits a Node 18+ runtime powered by `puppeteer`, `@fal-ai/client`, and `sharp`. Four subcommands cover different stages: `upgrade` to overhaul an existing site, `generate` to draft mockups from a brief, `describe` to recreate specifications from an existing image, and `iterate` to compare the coded result against `after.png`.

Without an exported `FAL_KEY`, the runtime stops immediately. The skill focuses strictly on visual styling; backend tasks or pure copywriting edits are outside its scope.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add fal-ai-community/skills --skill fal-redesign -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add fal-ai-community/skills --skill fal-redesign -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add fal-ai-community/skills --skill fal-redesign -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install fal-ai-community/skills fal-redesign
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add fal-ai-community/skills --skill fal-redesign -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/fal-ai-community/skills --path skills/fal-redesign
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add fal-ai-community/skills --skill fal-redesign -a opencode
```

### Claude.ai

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

## When to use it
- redesign an existing HTML page using AI image models
- extract design tokens into tokens.json and generate changes.md
- generate a fresh site layout from a text brief
- run a pixel-diff pass between the live code and reference image

## Example prompts
- Improve the design of index.html and prepare the build spec
- Run a visual design pass on this landing page using fal-redesign
- Run an iterate check against after.png to fix residual layout bugs

name: fal-redesign
description: Upgrade a coded website to award-tier, editorially-crafted design using fal.ai. Takes a local HTML file or a dev-server URL, screenshots it, has an opus-4.7 vision model write a gpt-image-2 edit prompt, uses fal-ai/gpt-image-2/edit to produce the redesigned reference image, then opus-4.7 vision writes a Markdown build-spec with a "Hard constraints" section + a tokens.json. Also supports iterate (screenshot implemented site → delta-spec vs reference) and greenfield generate (brief → mockup → single-file HTML). Invoke when the user says "improve the design", "make it world-class", "redesign this landing page", "upgrade this site", "design pass", or points at a local HTML / dev server for a visual review.

# fal-redesign

> **Runtime:** Self-contained Node runtime under `runtime/` (`runtime/bin/fal-site.mjs`). Does things genmedia CLI cannot (puppeteer screenshotting, multi-vision pipeline, file orchestration). First-time setup: `cd runtime && npm install`. Override the runtime path with `FAL_SITE_RUNTIME=/abs/path`.

`fal-redesign` turns "I coded a site, make it look amazing" into a concrete, implementable design pass.

```
your index.html → screenshot (1920×1200)
screenshot + brand → opus-4.7 writes a redesign prompt
screenshot + prompt → fal-ai/gpt-image-2/edit → after.png
after.png → opus-4.7 writes Markdown build-spec + tokens.json
 → returned to Claude Code / Codex
```

The agent reads `after.png` + `changes.md` + `tokens.json`, applies the spec to the real HTML, refreshes, optionally runs `iterate` for a residual pixel-fix pass.

## When to invoke

- User has a local `index.html` or a running dev server and asks to improve the design, make it world-class, redesign, polish, or run a design review.
- User describes a brand/product in freeform text and asks for a fresh site (greenfield mode → `generate`).

Do NOT invoke for:
- Copy-only edits (the skill is visual-design focused).
- Backend, build config, or infra tasks.

## Commands

All four modes are subcommands of the Node runtime. Invoke directly:

### `upgrade`: redesign a coded site
```bash
node runtime/bin/fal-site.mjs upgrade --target <path-or-url> [--context "..."] [--variants N] [--out <dir>]
```

Pass `--variants N` (2-8) to fan out into N distinct design directions in parallel. You get `after-01-<slug>.png`, `after-02-<slug>.png`, plus a `gallery.html` to compare them side-by-side. Pick one, then run `describe` on the chosen PNG to produce its build-spec.

Outputs in `<out>/`:
- `before.png`: current-site screenshot.
- `after.png`: redesigned reference image.
- `edit-prompt.txt`: transformation prompt fed to gpt-image-2.
- `changes.md`: Markdown build-spec with a leading "Hard constraints" section (also echoed to stdout).
