Conciseness

Every line is directive — no concept explanations, no padding, no restating what Claude already knows about accessibility. The ~19-line body covers procedure, exit criteria, and a counterpart pointer with zero wasted tokens.

Actionability

Concrete, specific guidance throughout: named elements ('<button>', '<label for>', '<a href>'), named ARIA mechanics ('aria-describedby', 'role="status"', 'alt=""'), and numeric criteria ('200% zoom and 320px width'). Falls short of the 5 anchor only in verification: 'axe (no serious or critical issues)' names the tool but gives no runnable command.

Workflow Clarity

A clear 7-step sequence ending in an explicit verification step, reinforced by a dedicated 'Exit criteria' section ('axe is clean, and the manual keyboard checklist is recorded for every touched route'). It lacks an explicit fix-and-reverify loop (what to do when axe still reports serious issues), which keeps it below the 5 anchor.

Progressive Disclosure

The skill is under 50 lines with no external references needed; the body is organized into clean 'Procedure', 'Exit criteria', and counterpart-pointer sections. Per the rubric's simple-skill guideline, well-organized sections alone warrant a 5, and no bundle files exist to pull in.

Specificity

The description enumerates concrete defect classes ('missing labels, invisible focus, keyboard traps, contrast, alt text, announcements, reflow'), states the approach ('using native semantics first'), and names verification methods ('verify with axe plus manual keyboard and screen-reader checks') — comprehensive concrete actions with no padding.

Completeness

Both are present: a clear 'what' (fix accessibility defects to WCAG 2.2 AA with verification) and an explicit 'when' ('Use for any accessibility finding'). The 'when' clause is explicit but could be more specific with concrete trigger phrases (e.g. 'when the user reports an a11y issue or mentions WCAG/axe'), matching the 4 anchor rather than 5.

Trigger Term Quality

Good natural keyword coverage ('accessibility', 'WCAG', 'axe', 'keyboard', 'screen-reader', 'contrast', 'alt text', 'labels', 'focus'), but the trigger clause 'Use for any accessibility finding' is generic and misses common variations users would say, e.g. 'a11y', 'screen reader', 'accessibility issue/audit'. Not clearly the 5 anchor, which requires comprehensive synonym coverage.

Distinctiveness Conflict Risk

Clear niche (WCAG 2.2 AA remediation) with distinct domain triggers ('accessibility finding', 'axe', 'screen-reader'); unlikely to fire for unrelated skills. It explicitly names its counterpart tester skill, further reducing overlap confusion.
