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

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.| Class | State | What that means |
|---|
| Skill authoring | Tested | A 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 audit | No qualifying skill | The 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. |
|---|
| Spec writing | Pinned, not run | A 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. |
|---|
| On-page audit | No qualifying skill | The 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. |
|---|
| Voice | No qualifying skill | The 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. |
|---|
| Code review | No qualifying skill | The 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. |
|---|
| Test writing | Declared empty | This class has declared its external slot empty and said so. The rule has not been run over this repository for it, and no candidate has been weighed. |

Licence status, per pin
What the licence check found beside each set of pinned bytes, run against that pin's own commit.| Pinned bytes | Licence | Licence file | Checked at |

| skills/skill-creator slot | Apache-2.0 | skills/skill-creator/LICENSE.txt | 3b3fad96af16 2026-08-31 |
|---|
| skills/doc-coauthoring rejected | No licence file | none | 3b3fad96af16 2026-08-31 |

| skills/brand-guidelines rejected | Apache-2.0 | skills/brand-guidelines/LICENSE.txt | 3b3fad96af16 2026-08-31 |

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.
- 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
