Conciseness

The body is tight (~35 lines) with actionable Quick Reference bullets and one- to two-sentence Check/Fix/Explain/Code Review sections; it assumes Claude's competence rather than teaching accessibility basics. Minor trimmable instances remain: the two-sentence motivational intro ("Users who need help... should not have to hunt for it") and the "Rule page:" URL that duplicates the frontmatter metadata, which keeps it just below the every-token-earns-its-place level 5.

Actionability

Guidance is concrete and executable for an instruction-only skill: "Check whether contact links, chat triggers, help-center links, or support phone numbers appear in the same relative order on each page", a specific fix ("keep their relative order stable across the flow at the same breakpoint"), and a concrete flag target ("exact pages or breakpoints where repeated help moves"). Minor gaps — no pass/fail criteria or worked example of an inconsistency at body level (both delegated to references/rule.md) — hold it at level 4 rather than fully copy-paste-ready level 5.

Workflow Clarity

The Check → Fix → Explain → Code Review sequence is clearly organized with each phase's scope defined, fitting the simple-skill pattern. It stays at level 4 because validation checkpoints are absent at body level: there is no re-verification step after the Fix (e.g. re-check pages at the same breakpoint after moving mechanisms), and pass/fail criteria live only in references/rule.md.

Progressive Disclosure

The body is a concise, well-sectioned overview, and the sole bundle reference — "For full implementation details, code examples, and framework-specific guidance, see `references/rule.md`" — is explicitly signaled, one level deep, and verified to exist in the bundle with exactly the promised content (code examples, standards, exceptions, verification). This matches the anchor for a clear overview with well-signaled one-level-deep references and appropriate content split.

Specificity

The description names the domain ("reviewing support UI across multi-page flows") and one concrete action ("Compare multiple pages in the same variation instead of reviewing a single page alone"), but does not enumerate the skill's capabilities such as checking relative order of help mechanisms or flagging inconsistent breakpoints, which appear only in the body. This matches the anchor for naming the domain with 1-2 concrete actions rather than the several specific actions of level 4.

Completeness

It explicitly answers both questions: the what is "Compare multiple pages in the same variation instead of reviewing a single page alone", and the when is an explicit "Use when reviewing support UI across multi-page flows such as checkout, onboarding, account recovery, or support journeys" with four concrete trigger phrases. This clearly matches the anchor for explicitly answering both what and when with concrete triggers, exceeding level 4 where the 'when' could be more explicit.

Trigger Term Quality

Natural phrases users would say are present — "checkout", "onboarding", "account recovery", "support journeys", "multi-page flows" — giving good keyword coverage. A few natural terms are missing, notably "help", "help center", "chat", "accessibility", "WCAG", and "consistent help" itself, which keeps it below the comprehensive-synonym coverage of level 5.

Distinctiveness Conflict Risk

The niche is fairly distinct — comparing support UI across multi-page flows in the same variation — with concrete flow-type triggers. It stays at level 4 rather than 5 because "reviewing support UI" could still overlap with general accessibility or UI-review skills, and omitting "consistent help" / WCAG terminology leaves minor conflict risk with closely related audit skills.
