Conciseness

The same routing information is restated four times: a ~20-row Quick Reference table where 17 rows point to `skills/accessibility-diag.md`, a dot-graph decision tree, a numbered Decision Tree list, and 16 Example Invocations of which 13 resolve to the same file. This is noticeably verbose with several padded sections (anchor 2), though not anchor 1 since nothing explains concepts Claude already knows — everything is operational.

Actionability

The xcui section gives concrete commands ("check `command -v xcui`", run `--help`, then `doctor`, an explicit AXe fallback verb list) and routing destinations are specific. However, all substantive fix guidance is deferred to `skills/accessibility-diag.md` and siblings that are not present in this bundle, and Critical Patterns are single-line mentions with no code — some concrete guidance, but incomplete with missing key details (anchor 3).

Workflow Clarity

The tool-availability workflow is genuinely well sequenced with validation (verify the executable, run `--help` and `doctor`, check `command -v axe` before fallback, explicit stop-and-report conditions). But the primary audit→fix workflow has no checkpoints — there is no verify-after-fix step such as re-running the scan or re-checking with VoiceOver, leaving the sequence present but checkpoints implicit (anchor 3).

Progressive Disclosure

References are one level deep and clearly signaled through the quick-reference table, but the referenced paths (`skills/accessibility-diag.md`, `skills/ux-flow-audit.md`, `skills/watchos-a11y.md`, cross-suite files) do not exist in this skill's bundle — no references/, scripts/, or assets/ directories are present — so navigation targets are unverifiable. Combined with the routing being restated across four redundant sections rather than consolidated, this sits at anchor 3 rather than 4.

Specificity

The only action verbs are the generic pair "fixing or auditing"; the enumerated terms ("VoiceOver, Dynamic Type, color contrast, touch targets, WCAG compliance, App Store accessibility review") describe issue types, not capabilities the skill performs. This matches anchor 3 (domain plus 1-2 concrete actions, not comprehensive) rather than 4, which requires several specific listed actions.

Completeness

The 'when' is explicit and strong ("Use when fixing or auditing ANY accessibility issue — …"), but the 'what' is only weakly implied by the verbs embedded in the when-clause — the description never states what the skill actually does or provides. This is the mirror of anchor 3 (one half clear, the other missing/weak), and below anchor 4, whose example pairs a substantive what with the when clause.

Trigger Term Quality

"VoiceOver", "Dynamic Type", "color contrast", "touch targets", "WCAG compliance", and "App Store accessibility review" are all phrases users naturally say. It falls short of anchor 5 because common synonyms and variations ("a11y", "screen reader", "text size", "font scaling") are absent.

Distinctiveness Conflict Risk

Accessibility is a clear niche with distinct, specific triggers unlikely to fire for unrelated skills. Not anchor 5 because "ANY accessibility issue" is broad and overlaps adjacent sibling skills in the same suite (ux-flow-audit, watchos-a11y handle gesture-only dead ends and watchOS VoiceOver respectively).
