What it is
[Skill](/docs/en/skills#bundled-skills). Convert your repo's React design system and upload it to [Claude Design](https://claude.ai/design), so designs it produces use your real components. Optionally name the design system, for example /design-sync Acme DS. A first-time sync verifies every component and can take a few hours on a large repo. Available on the Anthropic API. It needs claude.ai, which the CLI doesn't contact on Amazon Bedrock, Google Cloud's Agent Platform, Microsoft Foundry, or Claude Platform on AWS, or through a [Claude apps gateway](/docs/en/claude-apps-gateway#availability-and-limitations), so the command is unavailable there

Presence across releases
0The miner has never read a build containing this name. It is here because a changelog entry of ours names it, which is evidence that it existed and not evidence of which releases carried it. The inventory starts at v2.1.138 and everything older than that was never mined.
First cited
0No release's published evidence quotes this name. The ledger indexes the Evidence lines of every changelog on this site, so this says nobody here has ever quoted it; it says nothing about how old the name is.
Names beside it
Every slash command in the inventory starting /design, up to twelve of them.
/design[Skill](/docs/en/skills#bundled-skills). Draft UI mockups, screen flows, landing pages, or posters as artboards on one canvas, published as a Design [artifact](/docs/en/artifacts#draft-a-design-canvas), for example /design a settings screen for a mobile banking app. You edit the artboards in a desktop browser, and your edits save automatically. You can export each artboard as PNG or PDF. Requires a session where [artifacts are available](/docs/en/artifacts#availability) and Claude Code v2.1.265 or later. Available on the Anthropic API. On Amazon Bedrock, Google Cloud's Agent Platform, Microsoft Foundry, and Claude Platform on AWS, artifacts aren't available, so the command is unavailable there never mined
/design-loginAuthorize design-system access for /design-sync with your claude.ai account never mined
Read out of the published npm bundle release by release, and out of Anthropic's own documentation as this site captured it. Nothing on this page is a description anybody here wrote about what the slash command does. All slash commands.
