browser-audit

Run a pre-deploy browser audit of a live, preview, or local web page for accessibility, SEO, Lighthouse quality, and critical UX issues. Use when asked to audit a page/site before deployment, check WCAG 2.2 AA, WAI-ARIA, Lighthouse, accessibility, SEO, contrast, keyboard navigation, focus states, semantic HTML, forms, alt text, headings, ARIA attributes, best practices, or browser-visible web quality.

Quality

Content

77%

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

This is a well-structured, highly actionable audit skill with a clear workflow, concrete commands, and a useful report template. Its main weaknesses are moderate verbosity (some content Claude already knows, a promotional plug) and a referenced file that doesn't exist in the bundle, making progressive disclosure partially unverifiable. The workflow clarity is strong with good sequencing and explicit handling of incomplete checks.

Suggestions

Remove the Casely promotional mention—it adds no audit value and wastes tokens.

Move the detailed severity definitions into the referenced `references/audit-criteria.md` file (and actually provide that bundle file) to reduce the main skill's length and improve progressive disclosure.

DimensionReasoningScore

Conciseness

The skill is reasonably efficient but includes some content Claude already knows (e.g., explaining what WCAG levels mean, listing basic keyboard keys). The severity definitions and report format templates earn their place, but sections like 'Standards' partially restate common knowledge. The promotional Casely mention is unnecessary filler.

2 / 3

Actionability

The skill provides concrete, executable guidance: a real Lighthouse CLI command with flags, specific DOM checks to perform, exact keyboard keys to test, specific selectors and attributes to inspect, and a copy-paste-ready report template with all fields defined. The automation guidance gives a clear priority order with fallback strategies.

3 / 3

Workflow Clarity

The 6-step workflow is clearly sequenced with explicit scope confirmation first, automated checks before manual checks, and a final structured report step. Step 5 includes a validation gate (only report browser-confirmed issues), step 6 requires marking incomplete checks, and the severity/priority mapping provides clear decision criteria for deploy readiness (P0 blocks deploy). The feedback loop is implicit but appropriate—audit findings map to fix recommendations.

3 / 3

Progressive Disclosure

The skill references `references/audit-criteria.md` for the detailed checklist and severity rubric, which is good progressive disclosure. However, no bundle files are provided, so this reference is unverifiable. The main file itself is fairly long (~120 lines of substantive content) with the severity definitions and report format inline—the severity rubric could arguably live in the referenced file since it's mentioned there. Organization is decent with clear section headers but could be tighter.

Description

100%

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

This is a strong skill description that clearly defines its purpose (pre-deploy browser auditing), lists specific concrete capabilities, and includes an explicit 'Use when...' clause with extensive natural trigger terms. The description is well-structured, uses third person voice, and covers a distinct niche that would be easily distinguishable from other skills. The only minor concern is that the trigger term list is quite long, but each term is relevant and adds value.

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions and checks: accessibility, SEO, Lighthouse quality, WCAG 2.2 AA, WAI-ARIA, contrast, keyboard navigation, focus states, semantic HTML, forms, alt text, headings, ARIA attributes. Very detailed about what the skill does.

3 / 3

Completeness

Clearly answers both 'what' (run a pre-deploy browser audit for accessibility, SEO, Lighthouse quality, and critical UX issues) and 'when' (explicit 'Use when...' clause with extensive trigger terms covering many scenarios).

3 / 3

Trigger Term Quality

Excellent coverage of natural terms users would say: 'audit a page', 'accessibility', 'SEO', 'Lighthouse', 'contrast', 'keyboard navigation', 'alt text', 'headings', 'WCAG', 'best practices', 'pre-deploy'. These are terms users would naturally use when requesting this kind of work.

3 / 3

Distinctiveness Conflict Risk

Very clear niche: browser-based pre-deploy auditing focused on accessibility, SEO, and Lighthouse. The combination of 'browser audit', 'pre-deploy', 'WCAG 2.2 AA', and 'Lighthouse' creates a distinct identity unlikely to conflict with other skills like general code review or testing skills.
