v0.3.0

[0.3.0] - 2026-10-24

Claude Desktop extension: install open-design-0.3.0.mcpb from this release to update it.

Open Design now works for people who never open a terminal: a Claude Desktop extension with nothing else to install, designs in a folder you can see, a plain welcome and plain replies. It also adds design systems from a website, recommendations when you haven't picked one, and cards, small print and shop images you can sell.

• Fewer false alarms from check_open_design_artifact. Text in a scrolling block (a pre with overflow-x: auto) inside a rounded overflow: hidden box is no longer reported as clipped; ©, ®, ™ and arrows are no longer reported as emoji; and a contrast ratio just under the bar now reads 4.49:1, not 4.5:1.
• Claude Desktop extension. Each release now carries open-design-<version>.mcpb: the MCP server for Claude Desktop on its own Node, with no Node.js install, no npx and no download on first start, a settings form for the Figma token (kept in the system keychain) and a default design folder. With the plugin installed too, Claude sees one set of tools. Claude Desktop
• Chat without a folder. With the extension, a Claude Desktop chat with no folder makes real designs: use_open_design_managed_workspace opens a folder for each design in ~/Documents/Open Design/, and write_open_design_file saves the files Claude writes there. With the plugin alone, Claude says what's missing and can make a single page as a Claude artifact.
• init pins the server. The .mcp.json, .codex/config.toml and .claude/launch.json entries now name the CLI's own version, so a project's server matches its skills. Re-run npx @feimacode/open-design-agent-kit@latest init to upgrade both.
• Design system from a website. /open-design-design-system-from-url (and Open Design: Design System from Website in VS Code) measures a rendered site in your installed browser: the colours of its background, cards, text and main button (with its hover and pressed states), the fonts it loaded, its type scale, radii, spacing and motion. It writes DESIGN.md and tokens.css from the same measurements, then shows the site beside a sample page in the new tokens before saving. New tool: extract_open_design_design_system. Design systems
• Built-in design systems describe one look. In most of the template design systems, DESIGN.md and tokens.css named different colours and fonts, so briefs and Claude Design exports mixed two brands. Each one now has a recorded choice of which side is right, and the other side is corrected to match. Designs made in these systems will look different, because their tokens changed: agentic, application, artistic, bento, bold, cafe, claymorphism, clean, contemporary, corporate, cosmic, creative, dashboard, dithered, dramatic, elegant, energetic, enterprise, expressive, fantasy, flat, friendly, futuristic, glassmorphism, gradient, lingo, minimal, modern, neon, neumorphism, pacman, paper, perspective, professional, refined, retro, simple, skeumorphism, spacious, tetris, vibrant, vintage. Content sync
• Every built-in design system, ready for Claude Design. claude-design-systems/ holds all 198 in Claude Design's Design System format: hover and tint shades computed to real colours, a brand-book README, and a cover drawn from each system's own colours and shapes. In Claude's Add design system, give this repository and a system's folder (for example claude-design-systems/kami), or upload the folder. scripts/claude-design-system.ts export now writes your own systems in the same format and checks them. Design systems
• A welcome for first-time users. In a new Chat with nowhere to save yet, Claude says so in plain words, offers the two ways on (connect a folder, or install the extension), then asks one question, "What's it for?", with goals to pick from (promote an event, run a shop, get hired, show an idea). list_open_design_skills takes a goal and lists the goals with surface: "list". Your first design
• Designs in a folder you can see. In Claude Desktop, designs go in a visible Open Design/ folder inside the connected folder, or in ~/Documents/Open Design/<name>/ with no folder. PNG, JPEG, PDF and PowerPoint exports sit beside the design with plain names (seed-swap-flyer-A4.pdf) and never overwrite a file you made. Folders that already hold designs under .open-design/, and designs an earlier release made in ~/Open Design/, keep working where they are; OPEN_DESIGN_OUTPUT_DIR keeps the classic layout. Settings
• Plain replies. Every skill and prompt shares one voice: everyday words instead of jargon, no tool names or internal files, print terms explained once, files described the way you would find them, and one line on what to do next.
• Canva uploads from the server. publish_open_design_artifact_to_canva takes filePath and uploadUrl and sends the export to Canva's upload URL itself, so Claude Desktop Chat no longer needs a terminal for it. Only https canva.com URLs and files in the design's exports/ folder are accepted.
• Full paths when attaching files. Claude gives a file's full path when it attaches or shows a design with its own tools, so Claude Desktop can find it.
• Server: OPEN_DESIGN_DEFAULT_WORKSPACE and OPEN_DESIGN_MANAGED_ROOT; the server reports its real version.
• Browsing works before a folder is set. In Claude Desktop, list_open_design_skills, list_open_design_design_systems and the example and design-system pickers no longer refuse until Claude names a folder, since they only read the bundled catalog. list_open_design_skills with more than 40 matches now returns pages of 100 compact entries (id, name, a one-line summary, mode, source) with counts by mode, and takes an offset for the next page, so no listing overflows Claude's limit for one tool result. Remixable entries now say remixable: true instead of naming the bundled example.html path, which agents in Claude Desktop went looking for with a whole-disk find.
• Design system recommendations. Not sure which design system to use? When nothing is active and you haven't named a look, the agent now recommends 3 to 5 from what you asked for, or asks up to three quick questions first, the same way in every agent. New tool recommend_open_design_design_systems; list_open_design_design_systems now matches every word of a query ("warm fintech"). Design systems
• Cards and small print. New formats for game cards with rounded corners (trading-card, tarot-card, mini-card), small print (a5, a6, a7, postcard-4x6, business-card, business-card-us) and shop images (shop-product, shop-banner, shop-collection). The check warns when text sits in a corner the printer cuts round. Posters and print
• Cards for a print house. Print images now come out at 300 dpi with the bleed included and the dpi written into the file (dpi changes it). printHouse writes each face at a printer's exact upload size, starting with Board Games Maker; list_open_design_print_houses lists them. A card back (data-od-side="back") exports as -front and -back files, and a print PDF puts each back after its front. CLI: --dpi, --print-house. Send cards to a print house
• Sell what you make. Two new recipes: shop-pack (product images, a store banner, a parcel card and launch posts from your product list and photos) and card-set (fronts, a back and a proof sheet from your card list and art). Cost, supplier and note columns never appear on a design. New surfaces Online shop and Game cards, and goals Sell online and Make cards to print and sell. Sell what you make
• Into your shop. publish_open_design_artifact_to_shop puts the designs in Shopify through its connector, showing the matches first and creating new products only as drafts, or writes a folder ready to upload (images named by product, copy.md, and a Shopify products.csv) for Shopify, Big Cartel or Etsy. Put your designs in your shop
