Create or edit visual design artifacts as self-contained HTML: UI mockups, interactive prototypes, wireframes, landing pages, dashboards, app screens, slide decks, print documents, résumés, animations, 3D objects, diagrams, fliers, HTML email, and visual research reports. Also author reusable design systems, UI kits, brand tokens, and component libraries, or export slide-structured decks made with this skill to PPTX. Use only when the task actually creates or edits a visual deliverable, even if the user does not say "design". Architecture or protocol analysis, rendering-engine or Rust/WASM/backend implementation, and technical Markdown do not trigger it by themselves. In a larger task, load it when visual creation or editing begins.

Use this for a local, data-backed dashboard, metrics page, KPI tracker, scorecard, data visualization or recurring report that opens in the bundled live editor: a page or scroll story of charts, numbers and tables over datasets (a CSV/TSV/JSON file the user has, or data you gather and attach), with a Sources panel that shows where every number comes from. Read it when creating, filling, refreshing or revising one. You write the datasets, then the page as plain HTML, into the dashboard's own store with this skill's script. Not for a static HTML mockup or a picture of a dashboard.

Create and revise design systems in the Design System artifact format (project/design-system.json, tokens.json, a README brand book, component previews, fonts and asset groups) as local files, then open them in a local design-system page where the user can browse and edit tokens, type, components and assets. Use when the user asks for a design system or brand kit in this format, built from a code repository, a design tool or scratch, names claude-design-system or the Design System type, or wants to revise a folder that holds project/design-system.json. claude-slides and claude-design install these systems. Not for a free-form HTML style guide, UI kit or token page.

Make and revise designs in the Design (canvas) artifact format (project/canvas.json plus one .dc.html Design Component file per artboard) as local files, then open them in a local canvas editor where the user can view the artboards side by side, retype copy and adjust tweaks. Use when the user asks for an editable canvas of artboards in this format, names claude-design or the Design (canvas) type, or wants to revise a folder that holds project/canvas.json. Not for a one-off HTML prototype or a design exploration outside this format.

Use this for a local Motion film: a short animated video (10–30 s unless asked for more, 900 s at most), such as an explainer, product walkthrough or UI demo, launch teaser, logo sting, social clip, animated chart or title sequence, that plays in the bundled Motion player and exports from there to MP4 or GIF. A narrated one carries a voice track: a take a scene, made here with a speech provider of the user's or recorded by them, spoken and captioned by the player, the motion timed to its words. Everything on screen is code, a pure function of time, written scene by scene into the film's own store with this skill's script while the user watches it fill in. Read it when creating, continuing, finalizing or revising one. Not for editing real footage, subtitles or audio (that is a video editor), a still picture, a slide deck or a static HTML page.

Make and revise slide decks in the Slides artifact format (project/deck.json plus one HTML file per slide) as local files, then open them in a local slide editor where the user can present, retype, drag, and export PDF, HTML or PowerPoint. Use when the user asks for an editable slide deck or presentation in this format, names claude-slides or the Slides type, or wants to revise a folder that holds project/deck.json. Not for a one-off single-file HTML deck or prototype.

Use this skill whenever you are about to create ANY chart, graph, plot, dashboard, or data visualization, in ANY output medium (HTML/React artifact, inline SVG, matplotlib/plotly/d3/Recharts, PNG). Read it BEFORE writing the first line of chart code, choosing chart colors, building a stat tile / KPI row, or laying out a dashboard. Teaches a design-system-agnostic method - form heuristic, color formula with a runnable validator, mark specs, interaction rules. Default palette in references/palette.md.

Use this to make a finished motion video that has something to say: an explainer, a product or feature video, a data story, an article or report retold, a social short, an opener or title sting, or any other film with a point, most often with a voice-over. It works as the film's director: finds the one point and the picture that carries it, writes the narration for the ear, has it voiced with a speech provider the user picks, times every scene to the words, builds the film with the claude-motion skill, looks at its frames the way a viewer would and hands over the film in its player, open beside the chat from the first minute, to watch, comment on and change, with a film folder that stays editable; the MP4 follows when the user asks for it. Needs claude-motion installed beside it. Not for a quick animation with no script (claude-motion alone), editing real footage, or AI-generated video clips.
