Use when reviewing rendered HTML, interactive components, or design-system patterns related to Avoid scrolljacking and custom scroll behavior. Check native semantics first, then inspect keyboard behavior, focus flow, accessible names, and screen-reader output where relevant.

Quality

Content

57%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A clean, well-structured single-purpose rule skill that delegates detail to references/rule.md. It would score higher by removing the duplicated explanatory sentence, naming concrete verification tools, and adding an explicit validation checkpoint.

Suggestions

Remove the near-verbatim duplicate of the opening sentence in the Explain section to tighten conciseness.

Replace 'verify it feels native' / 'browser accessibility tooling' with named checks (e.g., specific keyboard/screen-reader tests or DevTools panels) to improve actionability.

Add an explicit validation step in the Check/Fix loop (e.g., 'After removing the override, re-test keyboard scroll and reduced-motion to confirm native behavior is restored').

Dimension	Reasoning	Score
Conciseness	Mostly lean with no concept padding, but the opening sentence and the 'Explain' section repeat the same phrase about disrupting navigation and assistive technologies nearly verbatim, which is unnecessary duplication.	2 / 3
Actionability	Concrete, specific guidance ('Remove JavaScript that overrides default scroll behavior', 'respect prefers-reduced-motion') is appropriate for an instruction-only skill, but 'verify it feels native' and 'browser accessibility tooling' are vague without named tools or commands.	2 / 3
Workflow Clarity	Check/Fix/Explain sections give a clear sequence for this simple skill, but there is no explicit validation checkpoint to confirm a fix actually restores native scrolling.	2 / 3
Progressive Disclosure	Concise overview with clearly signaled one-level-deep pointer to the verified references/rule.md, and well-organized sections — appropriate for a short single-purpose skill.	3 / 3
	Total	9 / 12 Passed

Description

90%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, third-person description with an explicit 'Use when' trigger and a concrete sequence of inspection actions. Minor specificity gap keeps it just below maximal, but it is clear, complete, and distinct.

Dimension	Reasoning	Score
Specificity	Names the accessibility domain and lists several concrete inspection actions ('keyboard behavior, focus flow, accessible names, and screen-reader output'), but is not a comprehensive list of distinct concrete actions like the top anchor.	2 / 3
Completeness	Explicitly answers both what ('Check native semantics first, then inspect...') and when ('Use when reviewing rendered HTML, interactive components, or design-system patterns').	3 / 3
Trigger Term Quality	Good natural coverage of terms users would say — 'scrolljacking', 'custom scroll behavior', 'rendered HTML', 'keyboard behavior', 'screen-reader output' — though a few common variations are absent.	3 / 3
Distinctiveness Conflict Risk	A clear niche (scrolljacking/custom scroll behavior in accessibility) with distinct, rule-specific triggers unlikely to fire for unrelated skills.	3 / 3
