# ui-design

Makes the agent output a design specification — palette, fonts, layout — before it writes any interface code.

## What it does

The skill kicks in when you need a visual direction rather than finished markup: style, screen hierarchy, typography, color, a prototype. The agent has to print a DESIGN SPECIFICATION with five parts — purpose, aesthetic direction, palette with hex codes, fonts, layout strategy — and only then touch the editor.

The rules inside are strict. Purple, indigo and blue-purple gradients are out. So are Inter, Roboto, Arial, Helvetica and system-ui. Emoji as icons are banned; use FontAwesome, Heroicons or similar. A plain centered layout with no creative break counts as a mistake. Before finishing, the agent runs a self-audit over color, fonts, icons and composition.

If your project already has approved brand colors or a design system, those win over the bans — the skill asks the agent to document which defaults were overridden and why. Installation runs through `npx skills add`, so you need Node.js and npm access. The skill points at sibling CloudBase skills through relative paths like `../web-development/SKILL.md`; when those files are missing, you have to install the full CloudBase plugin.

## Install

### Claude Code (native platform)

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

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add TencentCloudBase/skills --skill ui-design -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add TencentCloudBase/skills --skill ui-design -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install TencentCloudBase/skills ui-design
```

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

### Gemini CLI

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

2. **Platform CLI**
```bash
gemini skills install https://github.com/TencentCloudBase/skills --path skills/ui-design
```

### Windsurf (Devin Desktop)

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

### OpenCode

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

## When to use it
- pick a palette and typefaces before the first line of markup
- get a screen prototype with real hierarchy instead of centered card grids
- break away from the default look an agent produces on its own
- lock down a design spec that the implementation can follow
- keep a distinctive style while respecting an existing brand

## Example prompts
- Design an onboarding screen for a web app: spec first, then code
- Prototype a pricing page in an editorial style, no purple gradients
- Build a design system for a mini program: colors, fonts, layout

## Sibling skills (local only)

Sibling CloudBase skills ship beside this skill. Use local relative paths such as `../auth-tool-cloudbase/SKILL.md`.

If a referenced sibling skill file is missing from this environment, ask the user to install the full CloudBase plugin (or the missing skill). Do **not** HTTP-fetch remote skill or protocol markdown into the agent context.

## Activation Contract

### Use this first when

- The request is to decide visual direction, produce a design specification, create a prototype, or make layout, typography, color, and visual hierarchy choices for an interface.
- The implementation should follow a deliberate aesthetic rather than directly coding an already-approved design.

### Read before writing code if

- The response must choose typography, color, spacing, layout strategy, or other visual rules before code exists.
- The user asks for "design", "prototype", "look and feel", or "style" rather than straight implementation.

### Then also read

- Web implementation -> `../web-development/SKILL.md`
- Mini program implementation -> `../miniprogram-development/SKILL.md`

### Do NOT use for

- Backend-only tasks, database design, or pure API work without interface output.
- Straight implementation of an already-approved UI without new design decisions.
- Generic frontend coding requests where the visual direction is already settled.

### Common mistakes / gotchas

- Writing JSX, WXML, or CSS before outputting the design specification.
- Falling back to generic AI layouts instead of an explicit aesthetic direction.
- Jumping into implementation when the design intent is still unclear.
- Ignoring platform constraints after the visual concept is defined.

### Minimal checklist

- Read [UI Design Activation Checklist](checklist.md) before interface generation.

## When to use this skill

Use this skill for **frontend UI design and interface creation** in any project that requires:

- Creating web pages or interfaces
- Creating mini-program pages or interfaces
- Designing frontend components
- Creating prototypes or interfaces
- Handling styling and visual effects
- Any development task involving user interfaces

**Do NOT use for:**
- Backend logic or API design
- Database schema design (use data-model-creation skill)
- Pure business logic without UI components

## How to use this skill (for a coding agent)

1. **MANDATORY: Complete Design Specification First**
