What
DesignSync (and the DesignSync tool) now works even when the session authenticates with an API key or provider token, as long as a design credential has been stored via /design-login.
Details
- Previously, design access required expanding the main OAuth token with design scopes — impossible with API keys
- Now there is a separate credential slot (
designOauth) checked independently of the main session token - Error messages are updated to reflect this: the new message for needing authorization is "Run /design-login to authorize it with your claude.ai account — this works even when this session authenticates with an API key or a provider token."
- The DesignSync tool description is updated to note the
(or, for sessions without one, a dedicated design authorization from /design-login)path
Evidence
DesignSync error message (search for "DesignSync needs design-system authorization. Run /design-login", "designOauth")
