In the agent-skills stack this registry is tracking, it is the manage-and-serve layer that sits next to scanning a skill before install and gating what it can do at runtime. The honest read: it is young and thinly committed, and its own README is written for an agent to action rather than a person, so treat it as an early but useful piece, and remember it serves skills without vetting them."
