What probably matters to you Section of the release
What
Design errors now tell you that running /design login once from an interactive session on the same machine lets headless and SDK runs reuse that authorization, instead of only reporting that the command is unavailable.
Details
Applies to both the design sync path and the Claude Design tool. The interactive-session message no longer offers logging in with a Claude subscription as an alternative. Evidence
non-interactive runs here then reuse that authorization
Strings lifted out of the shipped bundle, so the claim above can be checked against them.

Names in this entry
slash /design Skill . Draft UI mockups, screen flows, landing pages, or posters as artboards on one canvas, published as a Claude Design artifact , 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 Claude Code v2.1.265 or later, a session where artifacts are available , and an account where the Design template is available ; if your organization has turned that template off, /design doesn't draft designs. 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
