Restate the design intent in one sentence before proposing rules.\n2. Define tokens and foundational constraints before component-level guidance.\n3. Specify component anatomy, states, variants, and interaction behavior.\n4. Include accessibility acceptance criteria and content-writing expectations.\n5. Add anti-patterns and migration notes for existing inconsistent UI.\n6. End with a QA checklist that can be executed in code review.\n\n## Required Output Structure\nWhen generating design-system guidance, use this structure:\n- Context and goals\n- Design tokens and foundations\n- Component-level rules (anatomy, variants, states, responsive behavior)\n- Accessibility requirements and testable acceptance criteria\n- Content and tone standards with examples\n- Anti-patterns and prohibited implementations\n- QA checklist\n\n## Component Rule Expectations\n- Define required states: default, hover, focus-visible, active, disabled, loading, error (as relevant).\n- Describe interaction behavior for keyboard, pointer, and touch.\n- State spacing, typography, and color-token usage explicitly.\n- Include responsive behavior and edge cases (long labels, empty states, overflow).\n\n## Quality Gates\n- No rule should depend on ambiguous adjectives alone; anchor each rule to a token, threshold, or example.\n- Every accessibility statement must be testable in implementation.\n- Prefer system consistency over one-off local optimizations.\n- Flag conflicts between aesthetics and accessibility, then prioritize accessibility.\n\n## Example Constraint Language\n- Use \"must\" for non-negotiable rules and \"should\" for recommendations.\n- Pair every do-rule with at least one concrete don't-example.\n- If introducing a new pattern, include migration guidance for existing components.\n\n<!-- TYPEUI_SH_MANAGED_END
