# design-system-governance

This skill lays out how a design system changes over time: ownership, contribution, versioning, deprecation. It fits teams where more than one group ships components.

## What it does

The skill walks through the questions a governance model has to answer: who owns the system, who may contribute, how changes get proposed and decided, how releases are numbered, and what happens with breaking changes. Three ownership models are covered — centralized, federated, and hybrid — each with its tradeoffs.

A seven-step contribution process follows: request, triage, design, review, build and test, release, communication. Versioning uses semver, with patch for fixes, minor for new components, and major for breaking changes. Deprecation and the breaking change policy get their own sections, including migration guides and console warnings for consumers.

Nothing to install beyond the skill file itself. It earns its keep once several teams touch the same component library and start arguing about who adds what. On a single team that edits components directly, the whole apparatus just adds drag.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill design-system-governance -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill design-system-governance -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill design-system-governance -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Owl-Listener/designer-skills design-system-governance
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill design-system-governance -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Owl-Listener/designer-skills --path design-systems/skills/design-system-governance
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill design-system-governance -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/Owl-Listener/designer-skills/tree/HEAD/design-systems/skills/design-system-governance/SKILL.md

## When to use it
- settle who owns which components in the design system
- write down the path from component request to release
- pick between centralized and federated ownership
- introduce semver and a changelog for a component library
- plan deprecation so consuming teams are not caught off guard

## Example prompts
- Draft an ownership model for our design system across three product teams
- Lay out the contribution process for a new component, from request to release
- Write a breaking change policy with migration steps for our library

# Design System Governance
You are an expert in the operational and organizational structures that keep a design system healthy over time.
## What You Do
You define the processes, roles, and decision frameworks that allow a design system to evolve without fragmenting — so contributors know how to participate, consumers know how to depend on it, and the system stays coherent as the product scales.
## Core Governance Questions
A governance model must answer:
1. **Who owns the system?** Dedicated team, federated contributors, or hybrid?
2. **Who can contribute?** Anyone, or only the core team?
3. **How are changes proposed and decided?** Request process, RFC, or open pull requests?
4. **How is the system versioned?** How do consumers know what changed?
5. **How are breaking changes handled?** How much notice, what migration support?
6. **What gets deprecated, and how?** Timeline and removal process?
7. **How is quality maintained?** Review process before merging new components?
## Ownership Models
### Centralized (Core Team)
A dedicated design system team owns all components. Consumers submit requests; the core team builds and maintains.
- High consistency, high quality
- Can become a bottleneck; slow to respond to product team needs
- Works best in large orgs with budget for a dedicated team
### Federated (Distributed)
Any product team can contribute components. A lightweight governance layer reviews and accepts contributions.
- Fast to grow; reflects actual product needs
- Requires strong review standards to maintain quality
- Works best in mid-size orgs with mature design practice
### Hybrid
Core team owns foundational components; product teams own domain-specific components with support from core.
- Balances quality with velocity
- Requires clear ownership boundaries ("core" vs "extended" library)
- Most common model in practice
## Contribution Process
Define the lifecycle of a new component or change:
1. **Request/Proposal**: product team identifies a need; submits a request with use case and context
2. **Triage**: core team assesses: is this generalizable? Does something similar exist? What's the priority?
```
