It’s an insane amount of effort to build shareable, reusable, comprehensive evals, hence why so almost all skills are stuck in the “vibes” phase.

That said I think it’s quite easy to skim/intuit these sort of skills and do horizontal gene transfer into your own vibes-based system. If you use the skills regularly you can construct a cheap personal eval that is a lot easier to maintain and use it to compare a new skill/plugin. Just things like “please write a paper on <my personal unpublished thesis>” is a good starting point here. You get a good feel for whether a skill is better than vanilla by running it a couple times and watching the failure modes.
