| Tier | Scope | Budget | Default action |
|---|---|---|---|
| Micro | single component or interaction | < 50 lines | implement directly |
| Meso | one page or screen | < 200 lines | implement directly |
| Macro | cross-page flow or information architecture shift | evaluate first | document and delegate to Vision when redesign is required |
| Lens | Scope | Check for |
|---|---|---|
| Micro | component | missing hover/pressed/loading/success/error states, silent failures, unclear affordances, destructive actions without confirmation or undo |
| Meso | page | empty/error/loading/offline/first-use states, information overload, weak hierarchy, vague CTAs, poor result feedback, broken data-display UX |
| Macro | flow | wayfinding gaps, dead ends, weak onboarding, poor progress cues, trust breakdown after submit or save |
Cross-cutting checks:
aria-live, missing prefers-reduced-motion handling, WCAG 2.2 focus appearance (≥ 2px outline, 3:1 contrast against adjacent), missing accessible authentication (no cognitive function test), redundant entry (don't re-ask data already provided).Score each heuristic 1-5 and use the canonical report format in ux-evaluation.md.

Single source of truth for Recipe definitions. Subcommand match wins over natural-language signal-keyword match.
| Recipe | Subcommand | Default? | When to Use | Read First |
|---|---|---|---|---|
| Usability Evaluation | usability | ✓ | Comprehensive UI/UX usability evaluation; SURVEY → EVALUATE → PRIORITIZE → PRESENT. Also load interaction-anti-patterns.md | reference/ux-evaluation.md |
| Cognitive Load | cognitive | Cognitive load and information density analysis; output redesign proposals | reference/cognitive-load-anti-patterns.md | |
| Feedback Design | feedback | Feedback and microinteraction design; include animation timing notes | reference/microinteraction-patterns.md | |
| Accessibility | a11y | Accessibility and WCAG 2.2 compliance evaluation; classify by level (A/AA/AAA). Also load accessibility-patterns.md | reference/wcag22-inclusive-design.md | |
| Keyboard Navigation | keyboard | Tab order, focus management, shortcut systems, roving tabindex, focus trap. For WCAG 2.2 SC 2.1/2.4 conformance use a11y; for useFocusTrap/useHotkeys production hooks use Artisan; for focus animation timing use Flow | reference/keyboard-navigation-patterns.md | |
| Mobile Touch | mobile | Thumb zone, tap targets, gestures, haptics, safe area, keyboard avoidance. For WCAG 2.2 SC 2.5.7/2.5.8 audit use a11y; for RN/Flutter/SwiftUI production use Artisan (or Native for store review); for gesture choreography use Flow | reference/mobile-touch-patterns.md | |
| Forms UX | forms | Field order, validation timing, error voice, progressive disclosure, multi-step, autofill/password-manager cooperation. For exact error wording use Prose; for React Hook Form / Zod wiring use Artisan; for WCAG 2.2 SC 3.3.x / 1.3.5 use a11y | reference/forms-ux-patterns.md | |
| Error States | error | Error UX as a system — classify failures (validation/permission/server/network), message hierarchy, recovery paths, inline vs toast vs page, retry/undo, post-error empty-state handoff. For exact wording use Prose; for status-code → message mapping use Artisan | reference/error-states.md | |
| Empty States | empty | First-use, zero-results, post-clear, post-error variants — illustration vs not, primary action vs templates, onboarding-cue vs invitation copy. For illustration use Ink; for first-time onboarding journey use Vision | reference/empty-states.md | |
| Loading States | loading | Latency-band strategy (skeleton ≤1s, spinner 1–10s, determinate progress >10s, optimistic UI for retries), perceived-speed tactics, skeleton/spinner/shimmer choice. For data fetching use Artisan; for animation curves use Flow; for backend speed use Bolt | reference/loading-states.md |
For natural-language input without an explicit subcommand. Subcommand match wins if both apply.
