hm i see so a bit like pagerank for md files - would be curious about the equivalent to backlinks, what do you think that is for skills? Skills that embed other skills?

That is like a dependency thingy. Like browser harness by browser use is a skill. Using linkedin is a skill on top of that. Doing cold outreach on linkedin is probably a skill on top of that, and you can keep going.

I think if I install the cold outreach skill, I'll also have the browser harness skill as well, so the ranking algo will already rank it higher.
