UI Visual Composition

Purpose

Help an AI agent create and critique polished visual UI through hierarchy, spacing, typography, color, depth, imagery, and finishing details. Treat visual design as functional communication: the interface should help users understand what matters, what belongs together, what can be acted on, and what has changed.

This skill covers visual design quality, layout composition, typography, color systems, depth, imagery, polish, accessibility, and frontend implementation choices that affect visual quality. It does not cover deep UX research, information architecture strategy, or frontend architecture except where those concerns determine visual composition.

When to use this skill

Use this skill when the user asks for UI critique, redesign, product-page improvement, frontend visual implementation, design-system guidance, style polish, layout refinement, typography, color palette, empty/error/loading state improvement, or visual QA of generated UI.

Also use it when producing frontend code for a visual interface, because component structure, semantic markup, tokens, state styling, responsive behavior, and accessibility details determine whether visual recommendations survive implementation.

When not to use this skill

Do not use this skill as the primary framework when the user is asking mainly for user research planning, product strategy, market positioning, analytics instrumentation, backend/frontend architecture, performance engineering, copywriting without visual presentation, or detailed interaction flow design. Use it only for the visual-design portions of those tasks.

Do not use it to justify arbitrary decoration. If a visual suggestion does not improve hierarchy, comprehension, perceived quality, accessibility, or fit with product context, remove it.

Core principles

Start with the feature, not the shell. Identify the concrete user task and content before designing navigation chrome, page framing, or decorative treatments.
Hierarchy is the backbone. Make the most important content and actions easiest to notice. Use size, weight, contrast, spacing, placement, and order before relying on color or ornament.
Use familiar patterns unless novelty has a purpose. Users bring mental models from other products. Preserve conventions for common controls, navigation, forms, and feedback unless the user’s brand or product goal justifies a deliberate departure.
Group by meaning. Proximity, common regions, alignment, and connectedness should match conceptual relationships. Ambiguous spacing creates ambiguous meaning.
Constrain choices with systems. Use type, spacing, color, radius, border, and elevation tokens instead of ad hoc one-off values.
Typography is interface structure. Choose type that fits the content and context, then set readable line length, line height, alignment, emphasis, and hierarchy.
Color must carry meaning safely. Use color to reinforce hierarchy, state, and brand, but never as the only signal. Maintain contrast and test against color-vision and low-vision needs.
Depth should explain layers. Shadows, overlaps, borders, and background shifts should clarify elevation, grouping, focus, or interaction—not create visual noise.
Aesthetics improve acceptance but do not excuse usability flaws. Polish can make users more tolerant and confident, but it can also mask problems. Verify clarity, accessibility, and task fit before celebrating beauty.
Simplify without hiding necessary complexity. Reduce visible choices and chunk complex tasks, but do not abstract away information users need to decide or recover.
Design for resilient real content. User-uploaded images, long labels, empty data, errors, loading, disabled states, and localization must not break the composition.
Explain tradeoffs in user-centered terms. Recommendations should reference user goals, comprehension, accessibility, system consistency, and implementation feasibility.

See references/principle-cards.md for each principle as a reusable card.

Default recommendations

Use these defaults unless the user gives context that makes another choice better.

Area	Default	Why it is usually best	Override when	Ask before overriding
Product/task focus	Begin with one core feature or screen goal	Prevents designing app chrome before content and actions are known	User is explicitly asking for global navigation, design-system shell, or IA	Ask for the primary task and the screen’s success criterion
Visual direction	Professional, warm, restrained, and content-first	Works for most productivity, SaaS, dashboard, admin, and commerce interfaces	Brand is playful, luxury, editorial, youth-focused, highly technical, or campaign-like	Ask for brand personality and examples
Information density	Comfortable spacing first; reduce only deliberately	Spacious layouts usually read as cleaner and clearer	Dashboard, pro tool, trading, ops, or data-monitoring context requires high density	Ask about density and scan speed needs
Layout strategy	Content-width container with clear groups; avoid filling the screen by default	Reduces line length and visual drift on large screens	Immersive canvas, map, media, spreadsheet, timeline, or data grid needs full width	Ask what content needs to stay visible together
Grid	Use a simple flexible grid plus tokenized spacing, not a rigid layout for its own sake	Helps alignment without forcing content into arbitrary columns	Editorial, marketing, or data-dense layouts need stronger grid logic	Ask about content types and responsive breakpoints
Typography	System UI or high-quality neutral sans for UI; pair with one expressive display face only when brand calls for it	Reduces loading risk and improves legibility	Editorial/brand work needs a distinct typographic voice	Ask for brand tone and font constraints
Type scale	Small set of reusable steps for body, supporting text, labels, titles, and display	Reduces inconsistent hierarchy	Existing design system has a scale	Ask for the design-system token source
Line length	Keep prose and long-form text in a readable measure; avoid edge-to-edge text	Improves scanning and reading comfort	Data tables, code, or short cards need different measures	Ask only if the content type is unusual
Color	Build semantic roles from a limited palette with neutral scale, accent scale, success/warning/error/info, and focus states	Supports consistency and accessibility	Brand palette is fixed or compliance/regulatory states are prescribed	Ask for brand palette and accessibility target
Contrast	Treat contrast as a functional requirement; verify text, icons, controls, and states	Prevents inaccessible or low-confidence UI	Large decorative text or nonessential illustration is exempt	Ask if the product requires a specific accessibility standard
Depth	Use a small elevation scale and one consistent light model	Creates layers without visual chaos	Brand is intentionally flat/brutalist or skeuomorphic	Ask only if depth direction is a brand choice
Imagery	Use high-quality, purpose-fit imagery; protect text overlays with scrims/gradients/containers	Images vary and can destroy readability	User provides fixed photography or UGC	Ask about image source and volatility
Borders	Use spacing, background, shadow, or subtle dividers before adding many borders	Borders add noise quickly	Data tables, legal forms, or dense settings screens need explicit separation	Ask if density or tabular precision matters
Empty states	Include helpful empty states with next action	Empty states are part of the experience, not blank failure	Empty state is impossible or intentionally hidden	Do not ask; implement by default
Motion	Use subtle, purposeful motion for feedback, continuity, and loading; respect reduced-motion preferences	Adds clarity without distraction	Product is entertainment-heavy or brand motion is a key differentiator	Ask about motion appetite and accessibility constraints
Frontend implementation	Use semantic HTML, design tokens, responsive CSS, visible focus states, keyboard access, and state variants	Preserves visual quality and accessibility in real UI	Prototype is static and disposable	Ask if production constraints or framework/design-system rules exist

Required user questions

Do not ask users to confirm routine best practices such as readable text, sufficient contrast, or clear hierarchy. Apply those by default.

Ask a focused question only when the answer materially changes the visual solution. Use the question tool or equivalent when available. Good triggers:

The product goal, primary task, audience, or platform is unknown and cannot be inferred.
Brand personality or visual tone could plausibly change type, color, density, imagery, or ornament.
The user asks for a redesign but does not provide the current UI, screenshot, code, design-system constraints, or success criteria.
Accessibility target, compliance context, or audience needs are stricter than ordinary inclusive defaults.
The UI will handle volatile content such as user-uploaded images, localization, very long names, unknown data density, or generated content.
The user requests novelty that could conflict with familiar mental models or platform conventions.
The user asks for frontend implementation and the target framework, design system, or CSS constraints matter.

When asking, include a recommended default and options. Ask one question at a time unless the user explicitly requests a thorough discovery process. Use the question-tool-ready prompts in references/decision-prompts.md for the full decision set.

Workflow: critique existing UI

When reviewing an existing UI, inspect in this order:

Task and context fit. Identify the primary user goal, audience, platform, and success criterion. If missing, infer cautiously and state the assumption.
Mental model and convention fit. Check whether common controls, navigation, search, forms, and feedback behave like users expect.
Information hierarchy. Identify the intended primary content/action. Verify that the visual hierarchy matches importance, not just document order or semantic severity.
Grouping and layout. Check proximity, alignment, common regions, screen width, responsive behavior, and ambiguous spacing.
Typography. Check font choice, type scale, line length, line height, emphasis, label treatment, alignment, and long-content behavior.
Color and contrast. Check palette roles, contrast, semantic states, color-only meaning, hue/saturation balance, and dark/light mode implications.
Depth and layer logic. Check shadows, borders, overlaps, surface colors, modals, popovers, cards, and focus hierarchy.
Imagery and media. Check image quality, crop, intended size, overlay text contrast, loading failures, UGC, and alt text needs.
States and resilience. Check empty, loading, error, disabled, focus, hover, selected, validation, destructive, and success states.
Accessibility and inclusion. Check perceptibility, operability, simplicity, forgiveness, keyboard flow, focus, touch target comfort, motion sensitivity, and screen-reader semantics.
Frontend feasibility. Check whether the visual recommendation can be implemented with tokens, semantic components, responsive CSS, and maintainable variants.
Prioritize fixes. Group findings into high-impact fixes, polish improvements, a
