# frontend-design

Strict visual guidelines that stop AI agents from spitting out generic purple SaaS cards, cramped tables, and unneeded sidebars in Tailwind and shadcn/ui.

## What it does

The skill enforces visual guardrails across frontend tasks before any component code gets written. The agent must inspect `.tasks/domain.md` for real brand colors, look into `public/brand/logos/` for SVG assets, and read through the local reference files. Stock SaaS purple palettes, Inter or Arial defaults, and dashboard panels chopped into dozens of rounded cards are banned.

Layouts must stay cardless by default, using open tonal bands, rows, and dividers instead of framed containers. Sidebars are forbidden unless explicitly requested in the prompt. Spacing stays generous inside both tables and compound controls. Contrast must hit WCAG AA ratios: 4.5:1 for standard body copy and 3:1 for large display text or icons.

Without the reference documentation inside `.agents/skills/frontend-design/references/`, the agent treats the task as a compliance failure before producing CSS tokens.

## Install

### Claude Code (native platform)

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

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add customware-ai/skills --skill frontend-design -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add customware-ai/skills --skill frontend-design -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install customware-ai/skills frontend-design
```

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

### Gemini CLI

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

2. **Platform CLI**
```bash
gemini skills install https://github.com/customware-ai/skills --path skills/frontend-design
```

### Windsurf (Devin Desktop)

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

### OpenCode

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

## When to use it
- prevent AI agents from generating generic purple SaaS dashboards
- configure shadcn/ui and Tailwind tokens around actual brand assets
- format open, cardless page layouts without cluttered sidebar navigation
- enforce WCAG AA contrast ratios across all buttons, inputs, and text

## Example prompts
- Build the settings page layout in React using frontend-design rules.
- Refactor this shadcn/ui table to follow the airy spacing and cardless guidelines.
- Set up Tailwind theme tokens using the brand palette from domain context.

  Strict frontend design guardrails for building modern, minimal-visual-noise, airy,
  non-generic app UIs. Use whenever creating or changing frontend UI, React components,
  shadcn/ui themes, Tailwind styles, app layouts, or first-version product screens.
  This skill complements vertical/domain skills like CPQ, CRM, and similar app builders:
  follow the selected domain skill's workflow and layout requirements, then enforce
  this skill's shared visual rules for brand-aware theming, generous spacing,
  typography, contrast, roundedness, shadows, surface hierarchy, cardless defaults,
  no-sidebar defaults, and anti-pattern avoidance.

# Frontend Design

This is a visual design guardrail skill, not a domain workflow skill. Domain skills own required product structure, terminology, workflows, and output views. This skill owns visual quality and must be applied inside that structure.

## Mandatory References

Before visual planning or implementation, read both files. Skipping either file is a skill violation.

- `.agents/skills/frontend-design/references/visual-style-references.md`
- `.agents/skills/frontend-design/references/shadcn-setup-and-theming.md`

## Required Workflow

1. Read the active task, domain context, and selected domain skills.
2. Read `.tasks/domain.md` when it exists. Extract brand colors, company name, domain tone, terminology, workflows, entities, statuses, roles, and constraints.
3. Read both frontend-design references.
4. Produce the design pass before coding:
   - **Vision**: domain-specific product and visual direction. Reject generic SaaS purple, card-heavy dashboards, and generic admin shells.
   - **First-version features**: working screens, controls, routes, dialogs, and localStorage-backed state.
   - **Design tokens**: primary, secondary/accent, background, canvas, focal contrast treatment, text, border, radius, contact shadow, status colors, typography, generous spacing, and cardless plan.
   - **Design direction**: enforce brand color usage, actual logo usage, airy spacing, airy inner density, rounded controls, strong input contrast, soft/tight shadows, minimal visual noise, cardless defaults, and authored composition. Where the selected domain skill does not specify structure, use stronger visual ideas like asymmetry, deliberate negative space, vivid accent hierarchy, motion, and atmospheric background detail.
5. Pass the design compliance gate.
6. Configure CSS variables, Tailwind/shadcn theme tokens, and the relevant shadcn component styles before building screen details.
