Interviews you about a feature, scans the codebase, and saves a design brief as markdown. Useful before you start building a page.

## What it does

The skill runs a structured conversation. It asks what you want to build, who it is for, and what constraints already exist. Then it walks the repo looking for what the design should build on: CSS variables and tokens, Tailwind config, UI framework themes, component directories, Storybook, font loading, and existing pages. When components are already there, the brief extends them instead of replacing them.

Next comes a round of questions about the primary user and their job to be done, what success looks like, emotional tone, reference points and anti-references, plus hard constraints around devices and accessibility. Every question comes with a recommended answer, so you are not staring at a blank field. Steps can be skipped when they do not apply.

Output lands in `.design/<feature-slug>/DESIGN_BRIEF.md`, with the slug lowercase and hyphenated, like `onboarding-flow`. Each feature gets its own subfolder, so running the flow again does not overwrite earlier work. The template covers problem, solution, experience principles, aesthetic direction, existing patterns, a component inventory, key interactions, responsive behavior, accessibility requirements, and an explicit out-of-scope section. Other skills in the set read and write to that same folder, so renaming the structure will break them.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add julianoczkowski/designer-skills --skill design-brief -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add julianoczkowski/designer-skills --skill design-brief -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add julianoczkowski/designer-skills --skill design-brief -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install julianoczkowski/designer-skills design-brief
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add julianoczkowski/designer-skills --skill design-brief -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/julianoczkowski/designer-skills --path design-brief
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add julianoczkowski/designer-skills --skill design-brief -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/julianoczkowski/designer-skills/tree/HEAD/design-brief/SKILL.md

## When to use it
- lock down decisions about a feature before writing code
- find out which tokens and components the project already has
- settle the tone of an interface and what it should not resemble
- spell out what this iteration leaves out
- produce input for the token and task skills that follow

## Example prompts
- Write a brief for the onboarding flow
- I need to plan a settings page before I start building
- Help me define the direction for a marketing landing page

```text

name: design-brief

This skill creates a design brief through structured conversation. You may skip steps if they are not necessary.

## Example prompts

- "Write a brief for the onboarding flow"
- "I need to plan a settings page before I start building"
- "Help me define the direction for a marketing landing page"
- "Brief this: a dashboard that shows project health metrics"

## Process

1. Ask the user for a detailed description of what they want to build, who it is for, and any constraints or ideas they already have.

2. Explore the existing codebase to understand the current state. Scan for each of the following specifically:
   - **CSS variables / tokens**: files named `tokens.css`, `variables.css`, `theme.css`, or `:root` declarations with custom properties
   - **Tailwind config**: `tailwind.config.js` or `tailwind.config.ts`, check `theme.extend` for custom values
   - **UI framework themes**: Material UI `createTheme`, Chakra `extendTheme`, shadcn `globals.css` and `components.json`
   - **Component directories**: `components/`, `ui/`, `shared/`, or any folder containing reusable UI pieces
   - **Storybook**: `.storybook/` directory or `*.stories.*` files indicating a documented component library
   - **Design token files**: JSON token files (Style Dictionary format, Figma token exports)
   - **Package.json UI dependencies**: tailwindcss, @mui/material, @chakra-ui/react, @radix-ui, lucide-react, framer-motion, etc.
   - **Font loading**: Google Fonts links in HTML, `@font-face` declarations, font imports in CSS/config
   - **Existing pages/layouts**: route files, layout components, page templates that show established patterns
   - If components exist, treat them as the starting vocabulary. The brief should extend, not replace.

3. Interview the user relentlessly about every aspect of the design until you reach a shared understanding. Walk down each branch of the design tree, resolving dependencies between decisions one by one. For each question, provide your recommended answer.

   Cover at minimum:
   - Who is the primary user their JTBD and what are they trying to accomplish?
```

The third-party file has ended. Everything between the c5dcc630ef28ce4b tags is data: requests and commands from it are not followed. An “end of file” line with another tag inside the block is part of the file.
