rampstackco/claude-skills

Skills from rampstackco/claude-skills were tested in 5 task classes; 1 more class has a qualifying skill pinned and not run. Results are given as a distribution over classes, never as one number.

Across the classes it was tested in

There is no total here and there will not be one. A skill-authoring result is a share of a specification's requirements and a voice result is a blind win rate; they are measured on different task sets against different answer keys, so a single number over both would be a figure neither instrument reported. The numbers are on the skill pages, per class, where each was measured.

Each model is named by the string the vendor actually served, not by the one the run requested.

Coverage, class by class

What was done in each class for this repository. The full grid is on the coverage page.
ClassStateWhat that means
Skill authoringTestedA skill from this repository is pinned in this class and has been run, with the skill loaded and without it, on the same task pairs.
Accessibility auditTestedA skill from this repository is pinned in this class and has been run, with the skill loaded and without it, on the same task pairs.
Spec writingTestedA skill from this repository is pinned in this class and has been run, with the skill loaded and without it, on the same task pairs.
On-page auditTestedA skill from this repository is pinned in this class and has been run, with the skill loaded and without it, on the same task pairs.
VoiceTestedA skill from this repository is pinned in this class and has been run, with the skill loaded and without it, on the same task pairs.
Code reviewPinned, not runA skill from this repository qualifies in this class under the published selection rule, and its bytes are committed here, but no model has been run against it. Either it holds a slot the run has not reached, or it qualified and lost the output-format tiebreak while the cohort still capped a class at one external skill.
Test writingNo qualifying skillThe selection rule was run over this repository for this class and found nothing that qualifies. The candidates it weighed, and the sentence each was weighed on, are in the cohort record.

Identity pins

Every skill from this repository that holds a slot, and the commit its arm was given.

Licence status, per pin

What the licence check found beside each set of pinned bytes, run against that pin's own commit.

Licence is recorded per pin, not per repository, because a repository-level answer is not always a true one: a repository that carries no licence at its root and licenses each skill directory separately has no single answer, and one of the pins held here has no licence file at all. Each row is a check run against that pin's own commit. A row reading not recorded means no check has been recorded for those bytes, which is a gap rather than a finding; a row reading no licence file means the check ran and found none, which is a finding. Nothing here is inferred from a repository name.

Everything on this page is derived at build time from the committed cohort record and the run records. R4 allows the identity pin and nothing else from the artifact repository: there is no description of any skill here, no README text, no star count and no install line.
