vibe-to-ui

A local design companion for vibe coding developers. It first classifies the target page archetype and density, then uses the user's product background to derive three plausible visual and spatial directions from references before formalizing any one of them into a design system. It extracts "style DNA" including motion systems, Consumer app UIUX needs, visual asset direction, mood boards, and previews, and turns vague aesthetic feelings into product-aware design decisions that actually fit the product surface. Inspiration may be a website URL, screenshot, images, music, or fuzzy intent — the agent adapts to what the user provides (see references/INSPIRATION-SOURCES.md). Cases can be saved into a global Inspiration Library under ~/.vibe-to-ui/inspirations/<product>/pages/<page>/ (full-scroll analysis + motion + annotated preview.html, with product-level synthesis) without putting raw cases into a profile. It can also persist a reusable Design Context profile under ~/.vibe-to-ui/profiles/<profile>/ (brand master, tokens, decisions, assets) and adapt it on demand into open-ended medium targets — examples include web, social-cover, and hyperframes, and users may define their own (e.g. linkedin, print-brochure) — without coupling user data to skill install/update. All exploration happens through standalone previews; the agent only touches the user's project when the user confirms a direction and asks to apply it.

Tip: Git-based Design Context remote sync (context remote / context sync) shares profiles/ and inspirations/ under ~/.vibe-to-ui via your own private repo. For hosted multi-project management beyond Git, see MonkeyUI SaaS.

When to use this skill

• User provides a website URL, screenshot, or design mockup and wants to extract its design system
• User provides a website URL or screenshot plus product context and wants the agent to extend it into 3 visual directions rather than copy it literally
• User wants the agent to first identify whether the target is a landing page, brand page, dashboard, B-end dense operations page, table-detail management page, docs page, onboarding flow, Consumer app / C-end app surface, or another page archetype
• User has a vague aesthetic feeling and wants to explore design directions with website URLs, inspiration images, or music recordings
• User shares a music recording or audio clip (a melody, song snippet, or recorded humming) to express the mood they want their UI to feel
• User describes a song, genre, or musical feeling they associate with their desired aesthetic
• User wants a page to feel more relaxed, editorial, cinematic, calm, spacious, premium, playful, or unlike a generic SaaS landing page
• User shares non-UI inspiration such as photography, landscapes, architecture, interiors, magazines, posters, packaging, fashion, album covers, film stills, illustrations, music, or video references and wants those signals translated into layout decisions
• User wants to define a motion system that matches the page's actual use case — including by sharing a live site URL for the agent to observe
• User describes a product personality or feeling (for example "reliable", "innovative", "playful") and wants motion guidance that matches
• User wants to create a mood board that stays appropriate for the target page type instead of drifting into the wrong archetype
• User has collected multiple reference images or site URLs and wants to see them synthesized into a cohesive visual story
• User wants a shareable design artifact that communicates aesthetic intent to collaborators or stakeholders
• User wants distinctive icons, illustrated feature icons, 3D object icons, social visuals, or generated brand assets that fit the product and design direction
• User has confirmed a design direction (from concept previews, mood boards, or design system previews) and wants to apply it to their project
• User wants to save brand visual language from a website URL or screenshot into a local Design Context profile (brand / product / client), separate from any one project repo
• User runs or asks for vibe-to-ui context --profile <profile> --target <medium> to load or generate medium-specific rules for any medium (examples: web, social-cover, hyperframes, or user-defined like linkedin, print-brochure) and hand them to the matching agent
• User wants a cross-project Inspiration Library — collect product pages (URLs/screenshots) under ~/.vibe-to-ui/inspirations/<product>/, get full-scroll aesthetic + motion analysis, product-level visual positioning, optionally link the product into a profile, and only merge the product design-seed.md into project DESIGN.md after confirmation

Reference Priority Rules

Before choosing a workflow, classify the user's inputs:

• Atmosphere / vibe reference: photography, landscapes, architecture, interiors, magazines, posters, packaging, fashion, album covers, film stills, illustrations, music, video, abstract feelings
• Concrete UI reference: website URLs, screenshots of products/webpages/apps, local projects, existing codebases

When both are present, always use this priority:

1. Concrete UI / project fidelity
2. Page type fidelity (goal, density, interaction model, module mix)
3. Visual material fidelity (image strategy, typography, density treatment, glass treatment, motion weight)
4. Atmosphere adjustment

Inspiration source intake

Adapt to whatever the user provides — website URL, screenshot, mood images, music, local project, description, or a mix. None of these is the default preferred channel. Follow references/INSPIRATION-SOURCES.md:

• If they share a URL → visit / fetch, read frontend cues, captures (Inspiration Library: full-scroll; other capabilities: selective), optional motion observation
• If they share a screenshot or image → analyze it directly; do not ask for a URL first
• If they share music / atmosphere / description → vibe path; do not insist on a live site
• If sources mix → use each for its role and state how they were weighted

This intake applies across Capabilities 1–4, Motion System, Mood Board, and Design Context whenever those source kinds appear — as equal options, not a URL-first policy.

Mandatory Stage 0: Page Type Identification

Before any design-system extraction, spatial-vibe exploration, mood-board generation, or project application, classify the target page type.

Always produce:

1. Primary page type
2. Secondary modifier if needed
3. Density level: low / medium / high
4. Confidence: high / medium / low
5. Evidence: the signals that drove the classification
6. Design consequences: what this classification means for spacing, hierarchy, imagery, components, and motion

Use these signals to classify page type:

• Business goal: conversion, browsing, monitoring, data entry, content consumption, configuration, execution
• Information density: how much content competes on screen at once
• Primary interaction mode: scrolling, reading, filtering, comparing, editing, approving, drilling into records
• Dominant modules: hero, feature grid, table, chart, sidebar nav, detail pane, form, wizard, feed
• Decision speed: emotional persuasion, calm reading, fast scanning, repeated operations

Common page types:

1. Landing / marketing page: persuasive storytelling, strong hero, lower density, higher visual drama
2. Brand showcase / portfolio: presentation-led, immersive imagery, editorial rhythm
3. Content / docs / editorial page: reading clarity, typographic hierarchy, stable navigation
4. E-commerce / catalog page: browsing, filtering, comparison, product-card systems
5. B-end dashboard / overview: metrics, monitoring, summaries, moderate-to-high density
6. B-end workbench / dense operations page: repeated actions, filters, tables, status chips, compact spacing
7. Data management / table-detail page: record list + detail + batch actions, strict scanability
8. Form / onboarding / wizard: guided steps, form grouping, completion feedback
9. Consumer app surface: C-end product experience, usually mobile-first or app-like, task-oriented but emotionally richer than B-end systems; often card/feed, tab, onboarding, empty-state, and detail-flow based

If the page is mixed, pick one primary type and note the secondary pattern. Example: "Primary: B-end workbench; Secondary: dashboard summary."

Two operating modes

• Reference Fidelity Mode: Use when the user provides a concrete UI, screenshot, live page, or local project. Goal: first match the page type and structural feel, then make the output look recognizably close to the reference before applying mood adjustments. To preserve the reference's layout structure, follow the structure-extraction path in references/SPATIAL-VIBE.md.
• Vibe Translation Mode: Use when the user provides only atmosphere references or abstract feelings. Goal: infer the intended page archetype from product context, then translate the mood into a UI direction that fits that archetype.

Default to Reference Fidelity Mode whenever a concrete UI or project is provided.

Non-negotiable rules

• Do not jump into free reinterpretation before identifying the target page type, density level, interaction model, page structure, typography hierarchy, material treatment, and motion intensity.
• When the mood conflicts with the page type, the page type wins first. Tune the vibe inside the archetype instead of changing the archetype accidentally.
• Do not produce a cinematic landing page treatment for a dense B-end workbench unless the user explicitly wants a strategic repositioning.
• For landing / brand / showcase surfaces, larger imagery, looser spacing, and more expressive motion are acceptable.
• For B-end dashboard / dense operations / table-detail surfaces, prioritize scanability, state clarity, compact but consistent spacing, form and table legibility, and restrained motion.
• For Consumer app / C-end app surfaces, prioritize mobile-first hierarchy, navigation clarity, touch feedback, state completeness, empty/onboarding quality, and brand memorability without turning the app screen into a landing page. Use references/CONSUMER-APP-DESIGN.md whenever this is the primary page type.
• If the reference's strongest signal comes from photographic landscapes, use real scenic imagery as the primary visual layer by default. Do not replace it with CSS-generated scenes unless the user explicitly asks for illustration or abstraction.
• When both a concrete UI reference and vibe images are provided, treat the vibe images as secondary; they should tune the output, not replace the reference structure or page type.
• When the user provides a concrete UI reference plus product background, default to reference-led exploration: derive 3 visual directions that stay faithful to the reference's page type and structural DNA while adapting mood, material, density posture, and motion to the user's actual product context.
• Use direct design-system extraction first only when the user explicitly asks for restoration, token extraction, exact replication, or "analyze this design system." Otherwise, a concrete reference should become source material for 3 contextual visual directions before token formalization.
• If page type confidence is low, ask one short clarification question before formalizing the design system.
• Default to visual output, not text-only output: for every exploration, extraction, mood-board, or spatial-vibe workflow, generate at least one standalone HTML visual artifact by default. Do not wait for the user to explicitly ask for a preview, visual draft, mockup, or demo.
• Do not stop at Markdown analysis alone when the workflow is meant to shape visual direction. Text analysis supports the visual artifact; it does not replace it.
• Before generating the UI, briefly summarize:
  • the inferred page type and density
  • what must stay similar to the reference
  • what may be adjusted
  • whether the task is operating in Reference Fidelity Mode or Vibe Translation Mode

Persistent DESIGN.md context

When a project has DESIGN.md, read it before visual design work and use it as persistent product/design context. When the file is missing and the workflow establishes meaningful product or visual strategy, create it from assets/DESIGN.md or add the relevant sections. See references/CONTEXT-COLLABORATION.md for the collaboration protocol.

Update DESIGN.md passively as the conversation reveals:

• product definition, users, use cases, personality, and constraints
• page type, density, interaction model, and design consequences
• confirmed visual direction, mood keywords, typography posture, motion personality, and imagery strategy
• icon_system: locked UI icon library, custom SVG fallback, preset, grid, stroke rules, and user overrides
• illustrated_icon_system: enabled surfaces, preset, format, visual family rules, style reference, and surfaces to avoid
• visual asset manifest paths, review surface paths, selected combinations, placement notes, validation status, confirmed assets, rejected assets, and regeneration notes
• active Design Context profile id when one is in use (e.g. design_context_profile: vibe-to-ui in Iteration Context)

Do not ask the user to manage this bookkeeping. Mention it only when it affects a design decision or when summarizing applied changes.

Local Design Context profiles (~/.vibe-to-ui/)

When the user wants reusable brand memory across projects or media, use Capability 7 and references/DESIGN-CONTEXT.md.

• A profile is a brand, product, or client (e.g. vibe-to-ui, acme-brand) — not an output platform.
• Live data lives only under ~/.vibe-to-ui/profiles/<profile>/. Skill templates under assets/design-context/ are seeds to copy, never the live store.
• Skill install, update, or reinstall must never overwrite, delete, or reset ~/.vibe-to-ui/.
• Prefer the Node CLI (bin/vibe-to-ui.js) for --list / --init / --target lifecycle, merge assembly, and optional Git remote sync (remote connect / remote status / sync).
• targets/<medium>.md files are created on first request for that medium (open-ended ids; web / social-cover / hyperframes are examples only), then reused and updated.
• Prefer an active profile's brand.md + tokens.json for brand fidelity; keep project DESIGN.md for product/page-local context.

Inspiration Library (~/.vibe-to-ui/inspirations/<product>/)

When the user wants to collect and understand external design references across projects, use Capability 8 and references/INSPIRATION-LIBRARY.md.

• Global library — not nested under a profile. Storage unit is a product with many pages (pages/<slug>/), not one folder per URL.
• Every URL page requires full-scroll captures + motion notes; product.md synthesizes multi-page visual DNA.
• Profiles may only store product references via inspiration-refs.json (reference-only by default).
• Do not copy raw inspiration cases into a profile. Default apply uses the product seed; write project DESIGN.md only after confirmation.
• Prefer the CLI: vibe-to-ui inspiration add|list|show|link|apply|rebuild-product.

Eight core capabilities

1. Design System Extraction (Design Style Restoration)

User provides a complete UI reference (website URL, screenshot, or design mockup) -> Extract the design system and generate a standalone preview page for the user to review before applying it to their project.

Trigger: User says things like "extract the style from this", "what's the design system here", "analyze this design", "analyze https://…", "what motion does this use", "replicate this closely", "restore this style", or clearly asks for exact tokenization rather than concept exploration.

Workflow:

1. Accept a website URL and/or a screenshot/image — whichever the user provides. If a URL is present, follow references/INSPIRATION-SOURCES.md for that link; if only an image is present, analyze it directly.
2. Run Stage 0: Page Type Identification
3. Analyze the reference systematically (live CSS/DOM + selective captures when from a URL), but interpret tokens through the page type lens:
   • layout rhythm and density
   • typography hierarchy and readability needs
   • color semantics, especially status and priority colors for B-end surfaces
   • component patterns that fit the classified archetype
4. Analyze the motion system with the page type in mind (Motion DNA only — do not load the Motion Engine Router yet):
   • landing pages can support more entrance choreography
   • dashboards prefer subtle transitions and focus-preserving movement
   • dense workbenches should avoid decorative motion that interrupts scanning
   • consumer apps need fast, tactile feedback, clear screen transitions, and complete reduced-motion fallbacks
   • extract tempo, easing, density, distance, personality, and one signature motion motif from the reference/vibe (see references/MOTION-SYSTEM.md)
5. Output a structured design system including:
   • page type summary
   • design constraints derived from the page archetype
   • visual tokens
   • motion tokens + signature motion motif
   • consumer app system fields from references/CONSUMER-APP-DESIGN.md when applicable
6. If the user wants a richer aesthetic guide (soul-level, not just tokens), also generate an Aesthetic Analysis document following references/AESTHETIC-ANALYSIS.md, but keep it subordinate to the page type constraints
7. Generate a standalone preview page as an HTML artifact showcasing the extracted design system applied to sample components. This is NOT applied to the project yet. When writing the preview's motion code, progressively load references/MOTION-ENGINE-ROUTER.md: compile Motion DNA → detect stack family (web / react / vue) → select one engine tier + stack binding → one primary recipe (mutate parameters from DNA/signature motif — do not ship recipe defaults unchanged) → dependency, mobile, and reduced-motion fallbacks. Only if the Router selects L5 MiniMax Video, load references/VIDEO-MOTION.md.
8. Ask the user to confirm or adjust both the page type classification and the extracted values
9. Once the user confirms, transition to Capability 5 (Apply Design to Project) to integrate the design system into the actual project

2. Design Exploration

User has feelings or vibes but no concrete design target -> Interactive conversation to discover and define aesthetics that still match the intended page archetype, generating standalone concept previews for collaborative exploration.

Trigger: User says things like "I want something that feels like...", "I have some inspiration images", "use https://… as inspiration", "I'm not sure what style I want", "explore other styles but keep these colors", shares mood or landscape photos, shares a music recording or song that captures the feeling they want, or provides a concrete UI reference (URL or screenshot) together with product context and wants the agent to extend it into multiple visual directions.

Workflow:

1. Ask the user about their project context:
   • what it does
   • who it is for
   • what the primary page type is, or infer it if the user does not know
2. Run Stage 0: Page Type Identification
3. Invite them to share inspiration in whatever form they prefer: website URLs, images, objects, landscapes, or music recordings and audio clips (see references/INSPIRATION-SOURCES.md). Adapt to what they send; do not steer them toward a URL.
4. If a concrete UI reference is present, split the signals into:
   • structural DNA to preserve: page type, composition rhythm, module mix, hierarchy logic
   • adaptable style dimensions: material treatment, typography attitude, density tuning, color temperature, motion character
5. For each URL, image, description, or music recording, identify aesthetic qualities:
   • color mood (warm / cool / muted / vibrant)
   • texture feel (smooth / rough / organic / geometric)
   • spatial impression (dense / airy / structured / fluid)
   • emotional tone (playful / serious / luxurious / minimal)
   • motion feel (still / flowing / snappy / bouncy / cinematic)
6. Separate signals into two buckets:
   • page-type constraints that should stay fixed
   • stylistic freedoms that can vary
7. Run Typography Exploration across the 3 directions. For each direction, explicitly define:
   • heading and body font pairing
   • typography attitude (editorial / neutral / operational / warm / premium / playful)
   • readability posture for the target page type
   • font weight strategy and hierarchy feel
   • fallback stack, including CJK-safe or multilingual fallback when relevant
   • why this typography direction fits the user's product background rather than only the reference image
8. Synthesize findings into 3 distinct design concept directions, each with:
   • clear inheritance from the reference or product context (references already imply palette + style — do not open a separate style menu by default)
   • a distinct typography direction, not just a color change
   • a motion personality and one signature motion motif (what makes this direction's movement memorable)
   • a density posture
   • a clear statement of why it fits the page type
   • for Consumer app surfaces, a distinct app experience posture: navigation model, primary loop, key state strategy, and tactile interaction feel
9. Generate a mood board for each concept direction — see references/MOOD-BOARD.md — as a standalone HTML artifact for the user to feel and compare
10. For each concept, generate a standalone concept preview page as a self-contained HTML artifact:

• a styled sample card or module from the actual page archetype
• the concept name, color swatches, typography rationale, font samples, and a mini layout demo
• motion preview using Exploration Interim Motion rules below (do not load the full Motion Engine Router yet unless the user asks to formalize implementation)
• explicit comparison between heading, body, label, and dense-data text where relevant
• for Consumer app surfaces, show realistic app modules from references/CONSUMER-APP-DESIGN.md: navigation, core screen, detail/create flow, non-happy state, and tap/sheet/tab motion
• these are standalone pages for exploration and do NOT modify the user's project

11. Let the user react, compare, and choose or mix elements. Only if they explicitly ask to explore other styles (or other palettes), run an on-demand pass: 3 options on that layer, prefer locking the other layer, then re-bind — see references/DESIGN-EXPLORATION.md
12. Once the user decides, apply Capability 1 (Design System Extraction) to formalize the chosen direction into a complete design system including motion tokens
13. Transition to Capability 5 (Apply Design to Project) to integrate the confirmed design into the actual project. On Apply, load references/MOTION-ENGINE-ROUTER.md for production motion code; load references/VIDEO-MOTION.md only when the Router selects L5 MiniMax Video.

Exploration Interim Motion (before Router load)

During Capability 2 concept previews and mood boards, motion must still feel intentional — but stay lightweight:

1. Draft a provisional Motion DNA per concept: tempo, easing, density, distance, personality, signature motif
2. Implement with CSS custom properties + CSS transitions/keyframes only in the standalone HTML (no GSAP/OGL/Three CDN demos)
3. Show one signature motif + essential feedback (hover/tap); for Consumer apps also show sheet rise and tab indicator using CSS
4. Vary the signature motif across the 3 concepts so comparison is about feeling, not only color
5. Forbidden in exploration: library default demos, fade-up-everything, bounce-everywhere, particle fields, purple glow loops
6. When the user confirms a direction and you need production-grade motion code, then load the Motion Engine Router

3. Spatial Vibe Exploration

User has a fuzzy aesthetic intent or mixed inspiration references and wants that feeling translated into page-level layout decisions.

Trigger: User says things like "make this landing page feel more relaxed", "I want an editorial, magazine-like feeling", "I like the vibe of this cafe, film still, and album cover", "use https://… for layout structure", "do not make it look like a generic SaaS landing page", or shares non-UI inspiration / site URLs and asks how it should shape the page.

Workflow:

1. Run Stage 0: Page Type Identification and clarify the product goal, UX constraints, target content, and any anti-references
2. Distinguish structure references (sources that inform page organization) from vibe references (sources that inform feeling, rhythm, density, and emphasis)
3. Identify what the user actually likes about each reference instead of copying the source literally
4. Translate references into transferable signals:
   • content density and whitespace
   • hierarchy and dominant visual focus
   • spatial rhythm, symmetry/asymmetry, and section transitions
   • card usage, image behavior, interaction tempo, and responsive strategy
5. Mark non-transferable signals that should not become literal UI decisions. Example: a coastal-road photo may imply openness, wide negative space, slow rhythm, and restrained density; it does not mean placing a road photo in the hero.
6. Dynamically derive the page's Spatial DNA from the product constraints and references. Do not use preset vibe templates or fixed style taxonomies.
7. Use an invisible composition grid as a private reasoning scaffold for alignment, rhythm, hierarchy, and responsive behavior; never expose it as a user-facing artifact or fixed template
8. Generate 3 genuinely different layout directions as standalone previews before modifying production code. Default to Mode A: three complete, comparable layout directions — each direction needs its own user-readable mini layout sketch or thumbnail, sketch legend/content map, Spatial DNA summary, section order, key layout decisions, tradeoffs, and responsive posture.
9. Do not show 3 shallow direction cards and then fully expand only 1 direction unless the user explicitly asks for a single recommended direction. If you recommend one, label it as the recommendation while still showing all 3 complete options.
10. Do not use unexplained architecture shorthand such as "copy", "cards", "idx", "specimen", or "CTA" without a legend. The user should understand what content each block contains and why it exists.
11. Review the rendered output and revise anything that feels generic, mismatched to the product, too literal to the references, unclear to the user, or unevenly detailed across the 3 options

4. Mood Board Generation

User wants to synthesize inspiration and aesthetic signals into a curated visual collage -> Generate an interactive HTML mood board that still respects the target page type.

Trigger: User says things like "create a mood board", "I want to see the visual direction as a board", "make an inspiration board", "synthesize these references into a mood board", or has collected multiple reference images or signals and wants a cohesive visual summary before moving to design system extraction.

Workflow:

1. Gather the aesthetic signals already established from Design Exploration, user-provided images, or direct description
2. Run Stage 0: Page Type Identification if it has not already been done
3. Curate and select. Not every reference belongs on the board; choose elements that reinforce a cohesive narrative for that page archetype.
4. Choose a mood board layout pattern that echoes the project's spatial personality and page type:
   • landing / brand: larger hero moments and stronger visual storytelling
   • B-end / data-heavy: UI fragments, density samples, type rhythm, state color discipline
   • Consumer app: mobile UI fragments, tab/feed/detail rhythm, empty/onboarding state tone, tactile motion cues
5. Generate a self-contained HTML mood board artifact with:
   • theme title and mood keywords
   • target page type and density note
   • dominant hero visual or representative UI fragment
   • color story with proportional swatches reflecting usage weight
   • typography specimens showing real text in proposed fonts
   • texture and material samples
   • spatial and motion cues
   • design principles or guiding statements
6. If the user is choosing between directions, generate multiple mood boards for comparison, one per concept
7. Present the mood board and invite the user's visceral reaction: "How does this feel?" not "Is this correct?"
8. Once the user confirms a direction, the mood board becomes source material for Design System Extraction (Capability 1)

5. Apply Design to Project

User has confirmed a design direction (from exploration concepts, design system preview, or mood board) -> Apply the finalized design system to the user's actual project.

Trigger: User says things like "apply this design", "use this one", "let's go with this direction", "integrate this into my project", "apply Concept B to my project", or confirms they are satisfied with a preview and want it in their codebase.

Applying a confirmed direction has two distinct layers. Confirm which the user wants — often both:

• Token application: visual and motion design tokens (color, typography, spacing, radius, shadow, motion). These are framework-agnostic values.
• Layout / structure application: the confirmed Spatial / Layout DNA and section composition (see Capability 3 and references/SPATIAL-VIBE.md). This turns the chosen layout direction into actual page structure, not just values.

Workflow:

1. Confirm the scope with the user — which layers to apply (tokens, layout, or both) and where in the project
2. Audit the user's project to understand existing framework, CSS approach, file conventions, and any existing design tokens or page structure
3. Re-check the confirmed page type classification so applied tokens and components stay aligned with the target surface
4. Apply tokens (when in scope): generate the appropriate token files (CSS custom properties, Tailwind config, JSON tokens) based on the user's tech stack, then integrate them — create new files or merge with existing ones, respecting project conventions
5. Apply layout (when in scope): translate the confirmed Spatial / Layout DNA and section order into the project's structure — semantic skeleton, section composition, grid/spacing relationships, and responsive collapse logic. Reuse the chosen layout direction rather than defaulting to a generic page template, and wire the applied tokens into that structure.
6. Present a clear summary of what was created or modified, separating token changes from structural changes
7. Invite the user to review and iterate — the collaborative spirit continues after applying

Important: This capability is the ONLY point at which the agent modifies the user's project files. All prior exploration (concept previews, mood boards, design system previews, layout direction previews) produces standalone artifacts that do not touch the project.

When the user confirms a direction with visual assets, also follow Step 3.5 in references/APPLY-DESIGN.md to deploy images and the asset manifest.

For Consumer app surfaces, also follow references/CONSUMER-APP-DESIGN.md during Apply: verify mobile-first layout, navigation model, tap targets, safe-area spacing, keyboard/input behavior, state matrix, and approved expressive asset slots.

6. Visual Asset Generation

User wants product-aligned illustrations (hero, feature, empty state, OG image) that share the same style DNA as the confirmed or in-progress design direction -> Generate assets via the host's image tool, record an asset manifest, embed in exploration artifacts, and deploy on Apply.

Trigger: User says things like "generate hero / illustrations for this concept", "replace mood board placeholders with real images", "create empty state illustrations", "apply with assets", or asks for visuals that match the current design exploration or design system.

Bundled visual-reference starter set

For an immediate image-led trial, this skill includes three visual-reference examples in assets/examples/visual-reference-directions/. When the user asks to use the bundled starter set, inspect the images and use each only as high-level input for its matching direction: editorial architecture (editorial-cobalt-glass.png), tactile material (tactile-amber-membrane.png), or quiet natural material (material-paper-glass.png). They are starting points, not brand canon: derive fresh, product-appropriate assets and never clone them or add any asset to the user's project before confirmation.

Workflow:

1. Run Stage 0: Page Type Identification if not already done — page type selects the asset pack (see references/VISUAL-ASSET-GENERATION.md)
2. Assemble StyleContext from product context, DESIGN.md, tokens, and aesthetic guide (from exploration or references/AESTHETIC-ANALYSIS.md)
3. Resolve the role-based icon strategy:
   • small UI chrome icons use the locked project icon library or custom SVG per references/ICON-USAGE.md
   • marketing/social/feature icons may use generated SVG/PNG/WebP illustrated families when they improve expression or the user asks for them
   • user overrides (library_only, custom_svg_only, generated_icons, raster_icons) are allowed and recorded
4. For each visual asset, declare the target display size and background mode before prompting; generated illustrated icons/objects default to transparent backgrounds when composited into UI, and image generation is not used below 64px unless the user explicitly overrides
5. Write a Visual Family Spec v1 with line language, perspective, material, lighting, background mode/complexity, composition system, subject policy, safe zones, and placement intent
6. Write an Asset Placement Spec per image so each asset has a real UI job: slot, purpose, size rule, copy/CTA relationship, safe zone, and responsive behavior
7. Write an Asset Spec per image (role, aspect ratio, target display size, background mode, composition, preset, style reference)
8. Compile prompts using the Prompt Compiler rules; generate hero or strongest family anchor first, then siblings with that anchor as style reference
9. Invoke the host image generation tool by default. Use MiniMax for static images only when the user explicitly selects it; then load references/MINIMAX-IMAGE-GENERATION.md before generation.
10. Run Consistency QA and placement fit checks (max 2 retries); on failure, fall back to CSS placeholders per references/MOOD-BOARD.md
11. Write design-assets.manifest.json next to exploration HTML; embed <img> paths in mood boards, contact sheets, placement previews, and concept previews
12. Run the Manifest Validator: file existence, dimensions/aspect ratio, target display size, background mode, file size, alt/decorative status, preview/final state, role/page fit, style lineage, placement fields, and icon-role constraints
13. Generate a review surface before Apply: contact sheet for variants, mood board wall for cross-role combinations, and placement preview for copy/CTA/layout fit
14. During exploration, use preview resolution; on Apply (Capability 5), regenerate or export final resolution and copy only confirmed/validated assets into public/design-assets/ (or framework equivalent)
15. Update the design system output and DESIGN.md with icon_system, illustrated_icon_system, visual family rules, review surface path, selected combination, placement notes, validation status, manifest paths, and regeneration notes
16. Default asset scope: illustrations, raster heroes, expressive illustrated icon families for marketing/social surfaces, and in-product consumer app assets (empty state, onboarding, badges) when page type is Consumer app

Important: Do not generate full-bleed hero imagery for dense B-end workbench surfaces unless the user explicitly overrides page-type defaults. UI navigation icons remain governed by references/ICON-USAGE.md (library + custom SVG first).

7. Local Design Context (Profile + Targets)

User wants reusable brand visual language extracted from a website URL or screenshot, persisted locally, and adapted on demand for different media agents -> Create or update a Design Context profile, then generate or reuse target rules and emit a merged handoff package.

Trigger: User says things like "save this site's design as a profile", "extract brand context from this URL/screenshot", "vibe-to-ui context --profile vibe-to-ui --target web", "give me LinkedIn rules for this brand", "print brochure context from this profile", "Hyperframes context for launch video", or asks to reuse a previously saved brand across projects or media.

Command surface (Node CLI in this package — prefer programmatic lifecycle over hand-rolled mkdir):

vibe-to-ui context --list
vibe-to-ui context --profile <profile> --init
vibe-to-ui context --profile <profile> --target <medium>
vibe-to-ui context remote connect <git-url>
vibe-to-ui context remote status
vibe-to-ui context sync

<medium> is any kebab-case medium id. Examples (not an allow-list): web, social-cover, hyperframes, linkedin, print-brochure.

Run as node <skill>/bin/vibe-to-ui.js ... or npx vibe-to-ui ... when the package bin is available. Root is always ~/.vibe-to-ui (no env override). See references/DESIGN-CONTEXT.md.

Workflow:

1. Resolve a kebab-case profile id (brand / product / client — not a medium). Prefer vibe-to-ui context --profile <id> --init to create the skeleton (shared seeds only; no targets/ yet).
2. Brand extraction (URL/screenshot/images) remains agent-led for now — write into the initialized profile's brand.md / tokens.json / decisions.md / sources/.
3. On --target <name>: run the CLI so it creates or reuses targets/<name>.md and prints the merged handoff package. Fill stub target content from the brand master using the guides in references/DESIGN-CONTEXT.md. Do not reject user-defined media.
4. Optional team/cross-device share: remote connect to a private Git repo, then sync (validates tokens.json, commits, rebase-pulls, pushes; aborts on conflict without overwriting). Use remote status to inspect ahead/behind.
5. When working inside a project, also read project DESIGN.md if present; optionally record design_context_profile: <profile> in Iteration Context. Do not replace DESIGN.md with the profile.

Non-negotiable: User data under ~/.vibe-to-ui/ is outside the skill lifecycle. Skill update or reinstall must never overwrite it. Remote sync reuses the user's Git credentials only — no OAuth, auto-merge, or cloud account in this MVP.

8. Design Inspiration Library

User wants to accumulate aesthetic cases, judgments, and transferable rules from product sites (multiple pages) or screenshots into a global library that later agents can search and cite — without treating those cases as brand canon or auto-writing the project.

Trigger: User says things like "save this as inspiration", "add to my inspiration library", "analyze this URL into inspirations", "collect this product's visual system", "vibe-to-ui inspiration add …", "link this inspiration to my profile", "apply this inspiration seed to DESIGN.md", or asks to keep a cross-project reference archive separate from brand profiles.

Command surface:

vibe-to-ui inspiration add <url> [--product <id>] [--page <slug>]
vibe-to-ui inspiration add --image <path> [--product <id>] [--page <slug>]
vibe-to-ui inspiration import-captures <product>/<page> --from-captures <dir>
vibe-to-ui inspiration rebuild-preview <product>/<page>
vibe-to-ui inspiration rebuild-product <product>
vibe-to-ui inspiration list
vibe-to-ui inspiration show <product>[/<page>]
vibe-to-ui inspiration link <product> --profile <profile>
vibe-to-ui inspiration apply <product> --project <path>              # product seed (default)
vibe-to-ui inspiration apply <product> --page <slug> --project <path>
vibe-to-ui inspiration apply <product> --project <path> --confirm

URL screenshots are agent-owned (Browser Use / Computer Use). The CLI does not launch a browser.

Workflow:

1. add <url> resolves product + page, fetches metadata, scaffolds pages/<page>/ (captureCoverage: awaiting-agent), and refreshes product index artifacts. Group related URLs with the same --product.
2. Full-scroll capture (required for every URL page): Browser Use / Computer Use writes fullpage.jpg + consecutive frame-01…N through page end into that page’s captures/, plus a short motion pass into motion.md. Then rebuild-preview <product>/<page>. Do not treat hero-only captures as complete.
3. Classify page type; fill the full-scroll visual positioning table; cover ≥4 of 6 aesthetic categories; tag observed / inferred / transferable / brand-specific. In annotations.json, give every viewport frame (frame-01…N) 1–3 notes (max 3; fullpage may omit anchors) and fill synthesis. Write all enriched library text in the user's prompt language (analysis, synthesis, frame notes, motion, seeds — not the source page locale by default). Collect 2–4 representative pages when the site has them, then rebuild-product <product> for cross-page DNA.
4. link <product> writes a profile inspiration-refs.json entry (reference-only) — never copies cases into the profile, never rewrites tokens.
5. apply <product> shows the product design-seed.md merge first (optional --page for a single page); write only after explicit --confirm.

Combining capabilities

These capabilities compose naturally. The workflow follows an explore -> choose -> apply pattern: the agent generates standalone previews for collaborative exploration, the user confirms a direction, and only then is the design applied to the project.

Pairing visual direction (Capability 2) with spatial direction (Capability 3)

Capability 2 (Design Exploration) and Capability 3 (Spatial Vibe Exploration) overlap in triggers — both accept vague feelings, inspiration images, and music — but they answer different questions:

• Capability 2 produces the visual concept: color, typography, material, and motion personality.
• Capability 3 produces the spatial concept: layout grammar, density, hierarchy, rhythm, and section composition.

A real page needs both, working together. Rules for combining them:

• Run both when the user is shaping a new page, not just restyling one. Color without layout (or layout without color) is half a direction.

• Bind, don't multiply. Do not present 3 visual concepts and 3 separate layout directions as 9 unrelated options. Pair them into a small number of coherent concepts, each with one visual direction locked to one spatial direction (for example "Concept A = neutral-cool palette + editorial asymmetric layout").

• Derive both from the same signals. The same keywords, music, and references feed both the visual and spatial translation, so a single concept reads as one intentional idea rather than two unrelated layers.

• Sequence by what is fuzziest. If the user is unsure about feel, explore visual concepts first; if they can feel the mood but not the page shape, explore spatial directions first. Either way, reconcile the two before formalizing.

• Record both in the design system document: visual tokens in their sections, and the chosen layout in the Spatial / Layout DNA section, so they apply together in Capability 5.

• Reference-led Exploration -> Choose -> Apply: Start from the user's product background plus a concrete reference, derive 3 contextual visual directions, user chooses -> formalize into design system -> apply to project

• Exploration -> Choose -> Apply: Explore vibes, generate 3 concept previews + mood boards, user chooses -> formalize into design system -> apply to project

• Exploration -> Mood Board -> Choose -> Apply: Explore vibes, classify page type, crystallize into mood boards for validation, user confirms direction -> extract design system -> apply to project

• Design Restoration -> Preview -> Apply: Extract design system from a complete design draft, classify page type, generate a standalone preview page -> user confirms -> apply to project

• Mood Board -> Extraction -> Apply: Generate mood board from references, formalize confirmed direction into design system -> apply to project

• Exploration -> Mood Board: Generate a mood board during Design Exploration as a mid-process checkpoint to let the user feel the direction without losing page-type fidelity

• Spatial Vibe -> Mood Board -> Choose -> Apply: Translate non-UI inspiration into Spatial DNA, crystallize the feeling in mood boards, choose a direction -> formalize -> apply

• Structure Reference + Vibe Reference -> Apply: Use one reference for page organization and another for spatial feeling, then reconcile both through the target page type

• Layout + Design System -> Apply: Analyze a layout from one site, classify its page type, then apply a design system from another source if the archetypes are compatible

• Layout + Mood Board: Extract a layout from one reference, then apply the mood board's visual direction without violating the target archetype

• Consumer App UIUX -> Preview -> Apply: Classify the app platform and lifecycle stage -> explore 3 app experience directions -> preview navigation, core screen, flow, state matrix, and tactile motion -> formalize tokens -> apply to mobile-first project components

• Source -> Design Context profile -> Target on demand -> Multi-medium handoff: Extract from URL/screenshot into ~/.vibe-to-ui/profiles/<profile>/ -> on first request generate targets/<medium>.md (any medium id: examples like web / social-cover / hyperframes, or user-defined like linkedin / print-brochure) -> merge brand + tokens + decisions + target for the consuming agent; reuse existing targets on later calls

• Design Context + project Apply: Load an active profile for brand fidelity, use project DESIGN.md for product/page context, then Apply (Capability 5) without inventing a parallel token system

• Inspiration Library -> link profile -> optional DESIGN.md apply: Collect product pages (full-scroll) under inspirations/<product>/ -> preview page + product synthesis -> optionally link <product> as reference-only -> only after confirmation merge product seed into project DESIGN.md

• Full pipeline: Identify page type -> explore feelings and references -> derive visual direction, Spatial DNA, Consumer app UIUX needs, and/or visual asset direction as applicable -> preview 3 comparable directions -> choose -> extract design system -> optionally persist as a Design Context profile and/or Inspiration Library case -> apply tokens, layout, and confirmed assets to the project

Output format guidelines

All design system outputs should include:

• Page type summary: primary type, secondary modifier if any, density, confidence, evidence, and design consequences
• Consumer app summary when applicable: platform assumption, lifecycle stage, primary loop, navigation model, gesture model, state risk, and state matrix
• Human-readable Markdown summary for documentation
• Standalone visual artifact by default: a self-contained HTML preview page generated automatically during the workflow
• Machine-readable tokens in at least one format:
  • CSS custom properties (:root { --color-primary: #xxx; })
  • Tailwind CSS config (tailwind.config.js theme extension)
  • JSON token file (for framework-agnostic use)
• Motion tokens: duration, easing, and animation definitions alongside visual tokens

Spatial Vibe outputs should include:

• page type classification and UX constraints
• structure references vs. vibe references
• what the user likes about each reference
• transferable and non-transferable signals
• dynamically derived Spatial DNA
• 3 distinct standalone layout direction previews with equal structural fidelity
• for each direction: user-readable mini layout sketch or thumbnail, sketch legend/content map, section order, key layout decisions, tradeoffs, and responsive posture
• notes from reviewing the rendered output and any revisions made

Icon usage guidelines

Never use raw emoji characters as visual elements in generated UI code. Always lock new small UI chrome icons to one project icon library when one exists. When no library icon fits or harmonizes with the page's aesthetic, create a custom SVG icon component that inherits the design system's tokens, matches the aesthetic soul, and passes the custom SVG QA checklist in references/ICON-USAGE.md. Do not turn a small icon into a miniature UI screenshot, diagram, dashboard, or multi-object scene; if an icon does not improve scanning or comprehension, let typography, labels, spacing, and hierarchy carry the meaning. Use generated raster or illustrated icons only for marketing, feature, empty-state, onboarding, social, or brand surfaces unless the user explicitly overrides the default. Record the icon strategy in DESIGN.md when available.

Important notes

• Explore first, apply later: Never modify the user's project files during design exploration. Generate all concept previews, mood boards, and design system previews as standalone artifacts. Only apply to the project when the user explicitly confirms a direction (via Capability 5).
• When the user asks for a design direction, extraction, or spatial-vibe exploration and does not explicitly opt out, automatically produce the corresponding HTML visual artifact in the same pass.
• When a user gives both UI references and atmosphere references, prefer "first make it look like the reference, then tune the mood" over redesigning from scratch.
• Always classify page type before locking a palette, spacing scale, typography scale, or motion language.
• For atmosphere-led pages, prefer fewer modules, larger scenic imagery, and lower information density by default, unless the product context clearly points to a denser archetype.
• For B-end dense pages, prefer clear state colors, strong table and form legibility, compact spacing discipline, and low-distraction motion.
• Always ask which CSS framework or tech stack the user is using before generating code tokens
• When extracting colors, provide both hex values and semantic names (for example primary, surface, accent, success, warning, danger where relevant)
• For typography, note both the font family and the scale ratios, not just absolute sizes
• Spacing should be expressed as a consistent scale (for example a 4px base unit)
• Motion tokens should always include prefers-reduced-motion fallbacks. Accessibility is non-negotiable.
• During exploration, use Exploration Interim Motion (CSS + provisional DNA + signature motif). Do not load the Motion Engine Router for mood boards or early concept feeling checks.
• When writing motion implementation code (design-system preview Step 7, confirmed concept productionization, or Capability 5 Apply), load references/MOTION-ENGINE-ROUTER.md. Detect whether the surface is web, React, or Vue, then use the simplest engine tier with the correct stack binding. When a native or generated video is proposed, run its Video Intent Route and load references/VIDEO-MOTION.md before writing markup: a directional opening defaults to one-shot hero-take with a held end frame; loop is permitted only for a certified ambient seam. The Router may select L5 MiniMax Video only for natural motion, complex transformation, or continuous cinematic movement that code cannot express well; use MiniMax only, and never substitute another provider. Mutate recipe parameters from Motion DNA and the signature motif — never ship unchanged library defaults. Never mix engines, cross-wire React packages into Vue (or vice versa), stack decorative effects, or copy demo aesthetics.
• Be honest when visual analysis is uncertain. Flag low-confidence extractions and suggest the user verify.
