The /design command connects Claude Code to Claude Design for working with visual prototypes directly from a code project. The interesting part is being able to explore a direction, see it rendered, and carry it through to implementation while preserving context. The danger is mistaking a convincing mockup for a finished website.
This tool is included in these collections: Skills for Claude Code, Codex and Coding Agents by Task · Design Resources for Coding Agents
We reviewed the official documentation, an English-language demo, and user experiences around the code handoff. We have not run our own end-to-end implementation. The previous version listed a launch date, an exact version requirement, and a separate quota, none of which current sources support. We removed them.
\nAnthropic described /design, /design-sync, and shared limits in their June 17, 2026 announcement. The current getting-started guide covers access from the web and Claude Desktop and its beta status. For compatibility and availability, that documentation takes precedence over any older tutorial.
Picture a landing page for a campaign. Before you wire up the form and the CRM connection, you need to decide what the visitor will actually see: the main message, the offer, the proof points, the call to action, and the reading flow. /design can help turn those decisions into visible alternatives.
A useful prompt is not \"make it look modern.\" It is \"I need a landing page to capture bookings; here are the customer objections, here are our components, and here are the three directions I want to compare.\" A solid brief does not disappear just because you have opened a terminal.
Anthropic documents importing design systems from repositories, files, and other materials, editing on the canvas, and moving between design and code. That expands the options for working with an existing brand. It does not guarantee every output will respect that brand without review.
\nTristen O'Brien walks through the workflow in English. At 2:26 he explains how to launch it; at 3:20 he works on the prompt for multiple options; at 4:45 he tackles the images problem. These are useful reference points, not a guarantee your account will have exactly the same interface.

\"it misses small details\"
DanyrWithCheese, Reddit
This user describes a page whose implementation preserved the general idea but changed details: underlined tabs became pill-style buttons. Their case covers the handoff from Claude Design to Claude Code; it does not mean every /design use will fail the same way.
\n\"a full design pattern library and rules in an MD file\"
mdutton27, in the same thread
They report success by handing over rules and patterns alongside the design assets. It is a positive experience with a specific method: making explicit what the implementation must preserve.
\nJordanJCaron also explains in that thread that requesting a Markdown handoff file to implement the pages has worked for them. These are not three controlled tests, they are one problem and two ways to address it. The useful takeaway is that the handoff package matters.

In another thread, lundren10 reports that exploring multiple directions for a mobile app was useful, but they accumulated over a hundred canvases and ended up having trouble opening the project. They recommend keeping the chosen option and clearing out the explorations. This is one experience from an earlier version, not a universal technical limit; they also share their own resources in the thread.
\n| Step | What to check | What not to assume |
|---|---|---|
| Brief | Objective, real content, and brand system | That the model understands priorities from a logo alone |
| Prototype | Hierarchy, states, and mobile version | That a polished screen covers edge cases or long copy |
| Handoff | Components, typefaces, images, and spacing | That sharing a link preserves all the details |
| Implementation | Form, navigation, accessibility, and tracking | That generated code leaves a campaign ready to publish |
I would save a screenshot of the approved design and another of the implementation at the same breakpoints. I would also compare the states that tend to get overlooked: open menu, error message, submitted form, and long content. If you only review the prototype hero screen, the most expensive details stay outside the test.
For a brand, I would ask for specific names and values: typeface families, weights, colors, border radii, and components. I would also verify the image sources. A placeholder box with a generic landscape may work for exploration; it is not an approved asset for a live campaign.
\nUsage draws from the shared limits Anthropic describes. Running multiple variations and redoing a handoff has a cost even when there is no price tag next to each button. To evaluate the tool fairly, measure the full journey: explore, choose, hand off, and fix the implementation.
I would not pit /design against Figma or Canva as if they were the same product. To choose between options, nail down the task first: exploring an interface from the repository, maintaining a design system across a team, or producing assets from an approved template. The answer can differ in each case.
\nI find it useful for closing the gap between \"I think it should look like this\" and a proposal the whole team can actually review. But the time savings have to be measured all the way through implementation. If you gain twenty minutes generating and lose two hours fixing the handoff, the balance is not what it looked like.
Try it on a small page with real content and an approved reference. If it preserves your visual system well and reduces revision rounds, expand the use. The prototype helps you decide; the tests decide whether the result is ready.
