## What it does

This skill turns the agent into an author of Terracotta design-system guidance. It ships the palette as tokens (`primary=#C56A3C`, `secondary=#F3E9D8`, `surface=#FFFFFF`, `text=#111827`), a type scale of 14/16/18/24/32/40, DM Serif Display with JetBrains Mono, and a spacing scale of 4/8/12/16/24/32. The look targets long-form reading, blogs and editorial layouts where rhythm and readability carry the page.

The workflow has six steps: restate the intent in one sentence, define tokens and constraints, write component rules, add testable accessibility criteria, list anti-patterns with migration notes, and finish with a QA checklist for code review. Output follows a fixed structure, and every rule has to be anchored to a token, a threshold or an example rather than an adjective.

Accessibility is pinned to WCAG 2.2 AA: visible focus states, keyboard-first interaction, touch targets of 44px and up. Here is the catch — if your project already has a design system, this skill will argue with it, because it pushes system-wide consistency over local fixes. Decide whose tokens win before you install it.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

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

## When to use it
- write a design system an engineer can implement straight away
- replace scattered hex values with named color tokens
- cover hover, focus-visible and error states for each component
- turn accessibility goals into criteria you can test in review
- collect anti-patterns and migration notes for legacy UI

## Example prompts
- Write the Terracotta design system for our blog: tokens, typography, component states
- Audit this article card against the Terracotta rules and list the accessibility problems
- Build a QA checklist for code review from the Terracotta guideline

# Terracotta Design System Skill (Universal)

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

## Brand
A sun-baked, clay-toned editorial interface built on warm cream surfaces, ink-brown headlines set in a display serif, and a single terracotta accent. Earthy, human, and content-first — tuned for long-form reading, blogs, storytelling, and editorial layouts where readability and visual rhythm matter.

## Style Foundations
- Visual style: modern, clean, high-contrast, playful
- Typography scale: 14/16/18/24/32/40 | Fonts: primary=DM Serif Display, display=DM Serif Display, mono=JetBrains Mono | weights=100, 200, 300, 400, 500, 600, 700, 800, 900
- Color palette: primary, neutral, success, warning, danger | Tokens: primary=#C56A3C, secondary=#F3E9D8, 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, 44px+ touch targets, high-contrast support

## 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
```
