anthropics/skills, tested in 1 task class
Skills from anthropics/skills were tested in 1 kind of task, and 1 more has a skill picked and not yet run. One kind of task at a time, and never as one number.
Across the classes it was tested in
How many task classes each result fell in. Counts of classes, not scores.| What happened | Classes | Which |

We do not add these together. A skill-authoring score is a share of requirements met. A voice score is how often a blind reader preferred it. They are different measurements of different things, so a single number over both would be a figure neither test produced. The numbers are on the skill pages, where each was measured.

We record the licence for each file we tested, not for the whole repository. Some repositories have no licence at the top and license each skill folder on its own, and one of the files here has no licence at all. Each row is a check against that file's own commit. A row reading not recorded means we have not run the check on those bytes yet. A row reading no licence file means we ran it and found none. Nothing here is guessed from a repository name.
- skills/skill-creator: Apache-2.0, in a LICENSE.txt inside the skill directory. anthropics/skills carries no licence at its repository root, so this per-skill file is the only licence covering these bytes. The file is byte-identical to the one beside skills/brand-guidelines, blob 4f881c52d1f72f4cfb720e339e2d35c3058d01a9.
- skills/doc-coauthoring: license: none found; bytes retained in this private repository for measurement only, never rendered
