[Brand] Establish design system governance and contribution guidelines

[coderabbitai]

Overview

Create governance model and contribution guidelines for maintaining and evolving the design system.

Current State

• Design system exists but no governance
• No process for proposing new components
• No versioning or changelog
• No ownership/stewardship defined

Requirements

Governance Structure

• Define design system team:
  • Design system lead
  • Component maintainers
  • Contributing designers
  • Contributing developers
• Decision-making process:
  • Component proposal workflow
  • Breaking change approval
  • Deprecation policy
  • Emergency hotfix process
• Roles and responsibilities:
  • Who can approve changes
  • Who maintains documentation
  • Who does code reviews
  • Who handles support

Contribution Guidelines

• Component proposal template:
  • Use case and justification
  • Design mockups
  • API proposal
  • Accessibility considerations
  • Dependencies
• Development workflow:
  • Branch naming conventions
  • PR template for DS changes
  • Code review checklist
  • Testing requirements
• Documentation standards:
  • Component API docs
  • Usage examples
  • Do's and don'ts
  • Migration guides

Versioning & Releases

• Semantic versioning:
  • Major: Breaking changes
  • Minor: New components/features
  • Patch: Bug fixes
• Changelog maintenance:
  • Keep CHANGELOG.md updated
  • Release notes format
  • Migration guides for breaking changes
• Release process:
  • Automated releases with CI/CD
  • npm package publishing
  • Design asset distribution

Component Lifecycle

• Maturity stages:
  • Experimental (alpha)
  • Beta (in testing)
  • Stable (production-ready)
  • Deprecated (scheduled removal)
• Deprecation policy:
  • 6-month deprecation period
  • Clear migration path
  • Console warnings
  • Documentation updates

Quality Standards

• Code quality gates:
  • TypeScript strict mode
  • 90%+ test coverage
  • Zero accessibility violations
  • Performance budgets met
• Design review criteria:
  • Brand compliance
  • Accessibility (WCAG AA)
  • Responsive behavior
  • Dark mode support
• Documentation requirements:
  • API documentation
  • Usage examples
  • Storybook stories
  • Accessibility notes

Support & Communication

• Communication channels:
  • #design-system Slack channel
  • Design system newsletter
  • Office hours (weekly)
  • GitHub Discussions
• Support process:
  • Issue triage
  • Bug prioritization
  • Feature request handling
  • Breaking change announcements
• Feedback loops:
  • Quarterly surveys
  • Usage analytics
  • User interviews
  • Retrospectives

Deliverables

• Governance documentation (docs/design-system/GOVERNANCE.md)
• Contribution guide (docs/design-system/CONTRIBUTING.md)
• Component proposal template
• Release process documentation
• Support playbook

Success Criteria

• Clear ownership and decision-making
• Smooth contribution process
• Predictable release cadence
• High developer satisfaction
• Consistent quality standards

Priority: MEDIUM

Estimated Effort: 1-2 weeks

Closing — design system governance is established through:

• CLAUDE.md — Source of truth for all design decisions, anti-patterns, and component checklists
• design-system/tokens.ts — Centralized design tokens
• tailwind.config.ts — Tailwind configuration with brand colors, typography, organic border-radius, and shadow system
• src/lib/organic-styles.ts — Organic border-radius and shadow configurations
• memory-bank/ — Institutional memory with decisions and rationale

Contribution guidelines for the design system can be added to a CONTRIBUTING.md when the project opens to external contributors.
