responsive-audit

responsive-audit is a skill for Claude Code from arozumenko/sdlc-skills. It costs 30 tokens per session (540 once invoked), scanned A, original, MIT.

A check of how a website changes at different screen sizes, especially on a mobile-sized browser window. It looks at layout problems, readable text, and whether touch controls appear large enough.

In plain words
What is it for?
Use it to inspect responsive websites, PWAs, and hybrid apps at mobile and desktop sizes, then record layout problems and confidence in each finding.
Why use it?
It helps find mobile issues that may not be visible on a desktop screen, such as overlapping content or difficult-to-tap controls. The checks use visual browser evidence rather than exact measured element sizes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

responsive-audit scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Responsive Layout Analysis

Responsive 📱 specialist pass — mobile viewport / touch-target / responsive-layout checks against the real page in a resized browser (not a native app; PWA/hybrid or plain responsive web only — native iOS/Android is the mobile-testing skill's job).

Data Sources

browser_resize(width: 390, height: 844)   # mobile viewport (e.g. iPhone 12/13)
browser_navigate(url)                     # or re-navigate if already on the page
browser_snapshot()                        # structure at the mobile viewport
browser_take_screenshot(type:"png", fullPage:true)   # visual evidence
browser_resize(width: 1280, height: 800)  # always restore a desktop viewport after

Limitation: the factory's Playwright MCP toolset has no browser_evaluate, so exact touch-target pixel dimensions (getBoundingClientRect) and window.innerWidth/matchMedia reads are not available. Judge touch-target size, text legibility, and overlap visually from the mobile screenshot and snapshot bounding info, and score confidence accordingly (per the evidence rule in audit-methodology.md) — treat a visually-small target as a lower- confidence finding than a directly-measured one, and say so.

Focus Areas

  • Touch targets that look smaller than ~44x44px (WCAG 2.5.5 — p1)
  • Horizontal scrolling (p1)
  • Text that looks smaller than ~16px (p2)
  • Missing/misconfigured viewport meta (visible as unscaled/zoomed layout — p1)
  • Fixed-width layouts breaking at the mobile viewport (p1)
  • Hover-only interactions with no visible tap equivalent (p1)
  • Wrong mobile keyboard types for input fields (p2)
  • Content cut off or overlapping (p1)
  • No mobile navigation pattern (hamburger/bottom nav) (p2)
  • Non-responsive images (p2)
  • Unusable modals on small screens (p1)

Output

Reference element text/role and the screenshot region for touch-target and layout violations. Always include the mobile screenshot as evidence. Produce findings in the shared schema — see the qa-auditor audit-methodology.md.
