Folder mapping (.umc)
Bind a repo to one of your projects with a .umc file, so a work folder reads your work profile and a side project reads your personal one.
In Claude Code and Cursor, a .umc file in a repo root binds that folder to one of your projects, so a work repo reads your work profile and a side project reads your personal one:
projectId=p2
handle=@workprojectId scopes the reads; handle is an optional readable label. Both values are shown on the project’s page in the web app, and the /umc skill can create or change the file for you. With no .umc file, the folder reads your account’s active profile.
