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

Component Rule Expectations

• Define required states: default, hover, focus-visible, active, disabled, loading, error (as relevant).
• Describe interaction behavior for keyboard, pointer, and touch.
• State spacing, typography, and color-token usage explicitly.
• Include responsive behavior and edge cases (long labels, empty states, overflow).

Quality Gates

• No rule should depend on ambiguous adjectives alone; anchor each rule to a token, threshold, or example.
• Every accessibility statement must be testable in implementation.
• Prefer system consistency over one-off local optimizations.
• Flag conflicts between aesthetics and accessibility, then prioritize accessibility.

Example Constraint Language

• Use "must" for non-negotiable rules and "should" for recommendations.
• Pair every do-rule with at least one concrete don't-example.
• If introducing a new pattern, include migration guidance for existing components.
