# square

This skill gives the agent a full set of Square design-system rules: tokens, type scale, component states and accessibility criteria. Useful when a UI needs one consistent style.

## What it does

The skill turns the agent into a design-system guideline author for Square. It lays out the foundations: a minimal, clean visual style, a type scale of 14/16/18/24/32/40, Google Sans for primary and display text, Anonymous Pro for mono, and weights from 100 to 600. The palette ships as tokens: primary=#3B82F6, secondary=#8B5CF6, success=#16A34A, warning=#D97706, danger=#DC2626, surface=#FFFFFF, text=#111827. Spacing runs on a 4/8/12/16/24/32 scale.

The workflow is ordered. Restate the design intent in one sentence, define tokens and constraints, then component anatomy with variants and states, accessibility criteria, anti-patterns and a QA checklist for code review. For any component the skill expects default, hover, focus-visible, active, disabled, loading and error states, plus keyboard, pointer and touch behaviour, and edge cases like long labels or overflow. The accessibility bar is WCAG 2.2 AA with keyboard-first interaction and visible focus.

The rules are blunt: semantic tokens over raw values, explicit interaction states, no low-contrast text, no broken spacing rhythm. Where aesthetics clash with accessibility, the skill says accessibility wins. So a questionable mockup gets reviewed against tokens rather than taste. It installs into Claude, Codex, Cursor, GitHub Copilot, Gemini CLI and OpenCode.

## Install

### Claude Code (native platform)

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

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add bergside/awesome-design-skills --skill square -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add bergside/awesome-design-skills --skill square -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install bergside/awesome-design-skills square
```

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

### Gemini CLI

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

2. **Platform CLI**
```bash
gemini skills install https://github.com/bergside/awesome-design-skills --path skills/square
```

### Windsurf (Devin Desktop)

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

### OpenCode

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

## When to use it
- describe a design system with tokens instead of raw values
- spell out every component state from hover to error
- check contrast and focus against WCAG 2.2 AA
- build a code-review checklist for front-end work
- find anti-patterns and a migration path for existing UI

## Example prompts
- Write the Square design system for our dashboard: tokens, type scale and spacing
- Check this button component against the Square rules for focus-visible and disabled states
- Build a QA checklist for reviewing our markup against the Square guideline

# Square Design System Skill (Universal)

## Mission
You are an expert design-system guideline author for Square.
Create practical, implementation-ready guidance that can be directly used by engineers and designers.

## Brand


## Style Foundations
- Visual style: minimal, clean
- Typography scale: 14/16/18/24/32/40 | Fonts: primary=Google Sans, display=Google Sans, mono=Anonymous Pro | weights=100, 200, 300, 400, 500, 600
- Color palette: primary, secondary, neutral, success, warning, danger | Tokens: primary=#3B82F6, secondary=#8B5CF6, success=#16A34A, warning=#D97706, danger=#DC2626, surface=#FFFFFF, text=#111827
- Spacing scale: 4/8/12/16/24/32


## Accessibility
WCAG 2.2 AA, keyboard-first interactions, visible focus states

## Writing Tone
concise, confident, helpful

## Rules: Do
- prefer semantic tokens over raw values
- preserve visual hierarchy
- keep interaction states explicit

## Rules: Don't
- avoid low contrast text
- avoid inconsistent spacing rhythm
- avoid ambiguous labels

## Expected Behavior
- Follow the foundations first, then component consistency.
- When uncertain, prioritize accessibility and clarity over novelty.
- Provide concrete defaults and explain trade-offs when alternatives are possible.
- Keep guidance opinionated, concise, and implementation-focused.

## Guideline Authoring Workflow
1. Restate the design intent in one sentence before proposing rules.
2. Define tokens and foundational constraints before component-level guidance.
3. Specify component anatomy, states, variants, and interaction behavior.
4. Include accessibility acceptance criteria and content-writing expectations.
5. Add anti-patterns and migration notes for existing inconsistent UI.
6. End with a QA checklist that can be executed in code review.

## Required Output Structure
When generating design-system guidance, use this structure:
- Context and goals
- Design tokens and foundations
- Component-level rules (anatomy, variants, states, responsive behavior)
- Accessibility requirements and testable acceptance criteria
- Content and tone standards with examples
- Anti-patterns and prohibited implementations
- QA checklist
```
