Design System was limited to Magpie admins. Anyone with a Magpie account can now create a Design System in Personal or in a team they can edit, import one from a codebase, share it and export it for coding assistants. The Brand section and its Brand Kit page are available in the same way.
An unlisted or public Design System or Brand Kit can be opened by anyone with its address, without signing in. Search engines can index public ones.
The assistant can search the selected team's Design Systems by name or description, filter them by sharing setting and count them. It does not read their tokens, components, rules or Brand section.
