Unclear The finding does not show whether the naming rules are enforced anywhere or only described.
What
When Claude proposes a new skill or an improvement to one, the proposal includes a slug, a short lowercase name with words joined by hyphens. The field's description now tells the model that the slug must not contain "claude" or "anthropic", and that a new skill's slug can be at most 64 characters long.
Only the description text changed. The only visible check on the field is that it cannot be empty.
Why
Proposed skill names should now avoid those two words and stay within 64 characters, because the model has been told to follow those rules.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
