This isn't an accurate take either. You can load client skills, sure, but the whole selling point from Anthropic is that skills are like memory, managed at the API layer "transparently" and that those skills are cross project. If you forced Claude to only use skills from the current project to try and be transparent, it would still be a black box that makes it harder to debug failures, and it'd still be agent and vendor specific rather than more human friendly and vendor agnostic.
