Title: Skills Library — show skill source/origin

Description: The Library lists all skills (~184 in my case) but doesn’t indicate where each skill comes from — whether it’s a Rebel built-in, a personal Chief-of-Staff skill, or from a named Space.

It would be very useful to have a source badge or filter in the Library UI showing:

System — Rebel built-in (
rebel-system/skills/)
Chief-of-Staff — personal custom skills
[Space name] — skills from a specific Space (e.g., “Florida AI Weekend”)
This would help users quickly find their own skills, understand what’s customisable vs. platform-maintained, and audit what’s been built across spaces.
