Conciseness

The 'Quick Reference' bullets ('Use rem/em units for font sizes instead of fixed px', 'Avoid fixed-height containers that clip text', 'Ensure containers grow when text size increases') duplicate the Fix section nearly verbatim, and the 200% test instruction appears in both Check and Fix ('Test at 200% zoom' / 'Test with browser text-size preferences'). That is a whole redundant section, which fits anchor 3 ('could be tightened') rather than anchor 4's 'minor instances'; it is above anchor 2 because there is no padded concept explanation Claude already knows.

Actionability

The Fix section names concrete techniques ('Use relative units (rem, em) for font sizes', 'Avoid fixed-height containers that clip overflowing text') but the body contains no code, specific commands, or concrete test steps — the executable CSS and browser-specific zoom instructions all live in references/rule.md. This matches anchor 3 ('some concrete guidance but incomplete, missing key details') rather than 4, since nothing in the body itself is copy-paste ready.

Workflow Clarity

A clear Check → Fix → Explain → Code Review sequence with validation checkpoints present ('verify no content is clipped, truncated, or overlaps' in Check, 'Test with browser text-size preferences' closing Fix). This matches anchor 4: most checkpoints are present but the re-test-after-fix feedback loop is implied rather than framed explicitly, keeping it below anchor 5.

Progressive Disclosure

The body is a lean, well-sectioned overview with one clearly signaled one-level-deep reference ('For full implementation details, code examples, and framework-specific guidance, see references/rule.md'), which exists and delivers exactly what is promised (executable CSS, browser zoom steps, framework examples, WCAG link). Content is appropriately split and navigation is easy, matching the anchor 5 example.

Specificity

Lists several concrete review actions ('Check native semantics first, then inspect keyboard behavior, focus flow, accessible names, and screen-reader output') with minor gaps in coverage. It falls short of anchor 5 because it never states what the skill actually does for the text-resizing task itself (e.g., flag or remediate resizing violations), and sits above anchor 3 because it names multiple specific actions rather than 1-2.

Completeness

Has an explicit 'Use when reviewing rendered HTML...' trigger clause plus a 'what' ('Check native semantics first, then inspect keyboard behavior, focus flow, accessible names, and screen-reader output'). Not anchor 5 because the 'what' is generic accessibility-review boilerplate rather than actions specific to text resizing; clearly above anchor 3 since both what and when are explicitly present.

Trigger Term Quality

Good keyword coverage including natural phrases users would say: 'rendered HTML', 'interactive components', 'design-system patterns', 'text resizing to 200%', 'screen-reader output'. Not anchor 5 because common variations and synonyms such as 'text zoom', 'font size', 'WCAG', or 'accessibility' are missing; above anchor 3 because coverage is broad, not just 'some relevant keywords'.

Distinctiveness Conflict Risk

'Support text resizing to 200%' establishes a clear niche with distinct triggers, but the trailing boilerplate about keyboard behavior, focus flow, accessible names, and screen-reader output would appear identically in sibling accessibility skills, creating minor overlap risk with closely related skills. This matches anchor 4 rather than 5.
