Read and write wiremark, the text-based wireframe DSL rendered from fenced wireframe code blocks and .wiremark files. Use when creating, editing, or interpreting wireframes, screen sketches, screen flows, or low-fidelity UI mockups in markdown documents.

Solutioning-phase UX planning skill (optional; activate when the project has a UI). Produces TWO planning documents: DESIGN.md (the visual system — design tokens, color palette, typography, spacing, component specs, WCAG 2.1 AA contract) and EXPERIENCE.md (user journeys, flow diagrams, screen states, error/empty/loading handling). Use when the user says "design the UX", "create UX planning docs", "define the design system", "map the user flows", "UX for this feature", "wireframe the flows", "...

Use when creating or improving a homepage/website and design rules are missing or weak. Artic is an agent design-direction protocol: @artic init interviews the user, @artic start authors strategy artifacts, then the compiler produces AI-native DESIGN.md docs from reusable reference principles.

Install, update, or remove claude-design-stack — a curated set of Claude Code design skills (impeccable, the taste suite, ui-ux-pro-max) plus a decision-table router. Use when the user wants to set up their design stack, "install the design skills", "set up claude-design-stack", add the design tooling, or uninstall it.

Forge suite — simulation bake and export skill. Bakes cloth, rigid bodies, soft bodies, particle systems, hair/fur (GN Curves), and Mantaflow fluid/smoke/fire headlessly in Blender, then exports to Alembic (.abc) or OpenVDB (.vdb) mesh-cache for downstream rendering and handoff. Use whenever simulating cloth on a character or fabric, running rigid body destruction or stacking, emitting particles or object-scatter, grooming hair or fur with Geometry Nodes, baking smoke/fire volumes, or exporti...

Forge suite — headless rendering engine and QA eyes. Drives Blender (Cycles/Workbench) to produce render outputs without a GUI: beauty stills, render passes/AOVs (normals, depth, AO, wireframe, UV checker), turntable sequences, 6-view orthographic sheets, and assembled contact-sheet PNGs that the model reads back to verify geometry, shading, and UV quality. Use whenever rendering a 3D asset to PNG, generating a QA contact sheet, setting up Cycles passes, enabling AOVs, doing a turntable rende...

Forge suite — web/runtime optimization pipeline for 3D assets: compress, budget, and hand off GLB files to the browser. Takes a raw GLB exported by Blender (or another DCC) and delivers a browser-ready GLB with Draco or Meshopt geometry compression, KTX2/Basis Universal or WebP texture compression, mesh quantization, LOD generation, and spec-validation — then produces the handoff package that atelier-webgl expects (optimized GLB + poster WebP + decoder paths). Use whenever: compressing a GLB ...

Forge suite — format matrix, glTF/GLB/USD/FBX export, and engine import conventions. Produces a validated, engine-ready asset (GLB, USDC, FBX, or USDZ) from any Forge working file. Use whenever: exporting a Blender scene or procedural mesh to glTF/GLB; converting FBX, OBJ, or STL to GLB; building a USD stage for multi-DCC pipeline; packaging USDZ for iOS AR / Quick Look; importing a GLB into Unreal Engine (Interchange, Nanite, FBX naming), Unity (FBX/glTFast, ORM pack, axis bake), or Godot 4 ...

Forge suite — animation craft layer. Authors keyframes and F-curves, sets interpolation and easing (BEZIER/BACK/ELASTIC/BOUNCE), builds NLA clip libraries, bakes IK/constraint/sim motion to raw TRS keys, and exports skeletal + morph (blend-shape) animation to glTF/GLB, FBX, and USD formats — all headlessly from bpy Python. Use whenever animating objects or armatures, setting up keyframes, editing F-curve handles, choosing easing (ease-in-out, overshoot, bounce, spring), creating looping idles...

Atelier suite — the entry point, router & orchestrator. START HERE when you're not sure which Atelier skill to reach for, want the suite to take a project from where it is to where it should be, or want to set up / read this project's design memory. With no argument it probes project state, decides which skills the situation needs, then RUNS them end-to-end by invoking each skill explicitly with the Skill tool (full `atelier-*` name) — pausing only for a skill's own creative input (tone, audi...

Atelier suite — the UX architecture & flows layer (planning-first). Decide how a product is STRUCTURED before any page is styled: the information architecture (content/feature inventory, grouping, sitemap, labels in the user's words), the navigation model (top-nav / sidebar / tab-bar / hub-and-spoke, URL structure, breadcrumbs, search), the critical user flows (signup → activation, the core task, checkout) with their dead-ends and decision points, and the five states every screen must handle ...

Atelier suite — expensive typography. Choose and pair fonts with a point of view, build a fluid modular type scale, control tracking/leading/measure, switch on the right OpenType + variable-font features, set editorial detail (drop caps, pull quotes, hierarchy), tune font loading for zero layout shift, and animate type (kinetic / scroll-driven) tastefully. Use this whenever typography matters: picking or pairing fonts, headings that feel generic or "default Inter/Playfair," body readability, ...

Atelier suite — scroll choreography & advanced interaction. Build award-grade scroll experiences: smooth/inertia scroll (Lenis), scroll-triggered reveals, scrubbing, pinning, horizontal sections, sticky-stacking cards, parallax, native CSS scroll-driven animations, page/route transitions (View Transitions API), infinite marquees, magnetic buttons, and custom cursors. Use whenever adding scroll-based animation or storytelling, smooth scrolling, parallax, pinned/horizontal sections, page transi...

Atelier suite — audit & upgrade existing sites/apps to premium without breaking them. Audit-first: inventory the current brand/IA/stack, name the specific AI-slop tells and the missing "expensive" levers, score gaps by impact vs risk, then apply the Atelier suite (direction → foundations → type → layout → motion → components → scroll/webgl) selectively, preserving functionality, content, SEO, and accessibility, and verifying with the perf/a11y gate. Use whenever improving, modernizing, polish...

Atelier suite — the performance & accessibility gate. The cross-cutting quality bar every Atelier build passes before it ships: animate only compositor-safe properties, hit Core Web Vitals (LCP ≤2.5s, CLS ≤0.1, INP ≤200ms), respect prefers-reduced-motion, meet WCAG 2.2 AA (contrast, focus, keyboard, target size, semantics, screen readers), give canvas/WebGL accessible fallbacks, and run the anti-slop "AI Tells" design-integrity check. Use whenever finishing or reviewing a frontend, optimizing...

Atelier suite — motion & micro-interactions (the "feel" layer). Add animation that reads premium, not gimmicky: correct easing/spring defaults, the right durations, the 12 animation principles applied to UI, component/gesture/layout/exit animation with Motion (motion/react), micro-interactions (buttons, toggles, likes), and the often-skipped states (skeleton/shimmer, optimistic UI, empty/loading/error). Use whenever adding or fixing UI animation, transitions, hover/press feedback, loading sta...

Atelier suite — the production-resilience pass. Make a beautiful build survive the real world: text overflow and truncation at every breakpoint, internationalization (30-40% text expansion, RTL mirroring via logical properties, locale-aware number/date/currency formatting, pluralization), the full set of error states (per-HTTP-status, offline, timeout, partial failure, form validation), empty and edge-case data (zero / one / few / many / huge, null fields, long strings, broken images), and in...

Atelier suite — the design-system engine. Build the token foundation that makes a frontend look coherent and "expensive": a perceptual OKLCH color system (ramps + semantic tokens + accessible dark mode), a modular + fluid type scale, an 8-point spacing scale, and depth (radii, shadows, grain). Outputs ready-to-use CSS custom properties, Tailwind v4 @theme (mapped to shadcn/ui theme variables), or W3C/DTCG design tokens. Use this whenever starting any frontend that needs a consistent visual sy...

Atelier suite — the data-visualization layer. Turn data into charts that read clear and premium, not rainbow slop: choose the right chart for the question, encode values honestly (position > length > color), build on the house stack (shadcn Charts/Recharts → Tremor → visx/D3 → ECharts), strip to signal (restrained axes/legends/grid, direct labels, tabular number formatting), and ship ACCESSIBLE charts (keyboard, data-table fallback, real alt/aria, reduced-motion) — because canvas/SVG is invis...
