Skill Health 100 (freshness and quality) estimated by backskills

Freshness 100 · Quality 100 · Efficacy not yet tested

Efficacy is shown once a skill has at least 10 use cases or a tools-enabled run. A small preliminary baseline has run and is not counted in this score.

Authors: run your own use cases with POST /api/skill-check (author-verified; never changes this public estimate). Paying never affects ranking. Author tests never change the public score. The public health score only breaks ties between equal matches.
