And it sometimes feels like these teams are not talking to each other. Using Claude Design? The way to hand it over to Claude Code is to download a .zip file with the html mockup and some description, which you then have to copy into Claude Code so it can use it.
The latest version of Claude code as of yesterday or day before has Claude design Mcp so you don’t need to do this now.
edit: note this may not be official release, and may be unavailable for some users. I saw it show up yesterday listed as available Mcp and used it to view projects in Claude design.
