dembrandt — UX Pipeline Orchestrator

Concept by @VictorGjn.

Routes multi-concern UI/UX tasks through six ordered stages. Each stage loads sub-skills on demand — only what the task actually needs.

When to use this skill vs a sub-skill directly:

• Multi-concern task ("design review", "audit interface", "build UI") → use this orchestrator
• Single-concern task ("check my colour palette", "review button states") → go directly to the sub-skill
• Brand-to-token-to-spec pipeline with a URL or DESIGN.md → use generate-ui-from-brand instead
• Reproducing an existing page rather than designing one → use clone-website instead

Pipeline

Stage 1 — Brand Foundation

Establish the visual language before making any token decisions.

Sub-skills (load as needed):

• brand-visual-language — shape language, icon style, typography tone
• algorithmic-color-palette — derive states and brand-tinted greys from brand colours
• color-mode-and-theme — light vs dark vs combined, when to offer a theme selector

Gate: Brand tone and colour system agreed before proceeding.

---

Stage 2 — Design Tokens & Scales

Pin the numeric system so all components share a common foundation.

Sub-skills (load as needed):

• modular-scale-typography — ratio-based type scales, minimum sizes, context-aware usage
• elevation-and-depth — shadow scale, border-radius, card and modal patterns
• button-states — six states: rest, hover, active, focus, disabled, loading
• component-family-consistency — buttons, inputs, pills: shared radius, colour, height
• sizing-units — px vs rem vs relative: which values move when the user enlarges text
• status-colors-and-errors — minimal semantic colours, error recovery, prevention

Gate: Tokens defined and consistent across component family.

---

Stage 3 — Layout & Structure

Apply layout decisions to the specific product context.

Sub-skills (load as needed):

• layout-paradigms-and-consistency — choose the layout paradigm that fits the content; reuse the same page skeleton across screens (macro-scale consistency)
• gestalt-ui-organisation — group related controls: proximity, similarity, common region
• visual-emphasis-and-hierarchy — one CTA per view, colour and size as emphasis
• information-architecture — naming, mental models, data UI, confirm dialogs
• ui-context-and-scope — hierarchy, breadcrumbs, colour regions, scope communication
• responsive-paradigms — mobile/tablet/desktop: nav, sections, sticky behaviour
• ui-density — match density to platform and user type
• sticky-and-fixed-elements — headers, bottom toolbars, z-index tokens
• scroll-areas — avoid inner scroll, one axis only, user-controlled

Gate: Layout is coherent across breakpoints and user contexts.

---

Stage 4 — Components & Interaction

Review component patterns and interactive states.

Sub-skills (load as needed):

• real-world-metaphors — cards, carousels, drawers: when to use and how
• tab-navigation — tab types, overflow, keyboard nav, ARIA, state persistence
• modal-and-overlay-patterns — tooltip/popover/drawer/modal hierarchy, focus management, destructive confirm
• form-design — helper text, placeholder, validation, submit state
• data-display-and-selection — grid/list/table, large hit areas, mass actions
• repeated-component-alignment — repeated components as slot models: equal size, pinned anchors, clamp + recover overflowing text
• operational-expert-tool-ui — dense, workflow-driven UIs for trained daily B2B users
• coordinated-data-views — keep a table and a visual view (map, diagram, chart) synchronized
• domain-expert-configuration — expose solver/algorithm settings in domain language
• authentic-product-representation — real content and real output over staged mockups and marketing chrome
• app-shell — top bar, app launcher, tenant and environment cue, status bar: one shell across an estate
• global-toolbar-controls — currency, language, region and unit selectors
• notifications-and-recovery — toasts, banners, retry, undo — always a path forward

Gate: All interactive states handled; no dead ends.

---

Stage 5 — UX Polish

Apply UX principles and motion to sharpen perceived quality.

Sub-skills (load as needed):

• nielsen-usability-heuristics — 10 usability principles with review checklists
• user-flows-and-guided-paths — wizards, purchase flows, onboarding sequences
• micro-interactions — animated icons, toggles, reveals, celebrations
• loading-states-and-perceived-performance — spinners, skeleton screens, staggered entry
• motion-and-storytelling — Disney principles and cinematic language in UI

Gate: Flow is legible end-to-end; perceived performance is acceptable.

---

Stage 6 — Accessibility & Technical Gate

Hard ship gate. Do not skip or defer.

Sub-skills (load as needed):

• wcag-accessibility — WCAG 2.2 AA / EN 301 549: contrast, keyboard, ARIA
• semantic-html-and-seo — HTML5, alt texts, Open Graph, progressive enhancement
• performance-and-web-vitals — Lighthouse audit, LCP, CLS, INP, images, fonts, JS loading

Gate: Passes WCAG 2.2 AA. Required by EU Accessibility Act (EAA) for products launched after June 2025.

---

Output

Produce one structured review, not a stream of loose comments. Group findings by severity, most blocking first:

1. Blockers — fails a hard gate: WCAG 2.2 AA, a broken flow, a dead end. Must fix before ship.
2. Major — breaks consistency, hierarchy, or a core UX principle. Fix this iteration.
3. Minor — polish, micro-interactions, perceived-performance refinements. Backlog.

For each finding give the stage it came from, the specific element, what is wrong, and the concrete fix.

Run only the stages the task needs. An existing product with settled brand and tokens starts at Stage 3; a pure accessibility pass runs Stage 6 alone. State which stages you ran and which you skipped, and why.

Relationship to generate-ui-from-brand

generate-ui-from-brand is a token-extraction pipeline: URL or DESIGN.md → tokens → UI spec. It overlaps stages 1–2 of this orchestrator. Use it when you have a brand source and need a concrete spec. Use this orchestrator when you are reviewing or building across the full stack of UX concerns without a specific brand-extraction starting point.
