"Technical UI audit — a11y, performance, responsive. Produces a prioritized findings table. Invoke when the user asks for audit on their UI, or mentions 'audit' alongside design / UI / frontend work."
Install
npx skillscat add educlopez/ui-craft/audit Install via the SkillsCat registry.
Context: this sub-skill is one lens of the broader ui-craft skill. If the ui-craft skill is also installed, read its SKILL.md first for Discovery + Anti-Slop + Craft Test, then apply the specific lens below.
Run a technical audit of the UI at $ARGUMENTS. Load the ui-craft skill and apply the audit lens.
Step 0: Visual capture (mandatory)
Code-only review is insufficient. Every audit/critique starts with the surface as the user sees it. Try the following in order; use the first one available:
- Playwright MCP — if
playwrightMCP server is available, use it. Capture full-page screenshots at three viewports: desktop (1280×800), tablet (768×1024), mobile (375×812). Capture dark mode if the app supports it. - Browser DevTools / Chrome MCP — second choice; same viewport set.
- Other browser automation (
agent-browser,cursor-ide-browser) — third choice. - Ask the user — last resort. If no automation is available, request screenshots from the user before proceeding. Be specific:
- "Visual review needs screenshots. Please provide:
- Full-page at 1280px (desktop)
- Full-page at 768px (tablet)
- Full-page at 375px (mobile)
- Dark mode of each, if supported."
- "Visual review needs screenshots. Please provide:
Do not begin the review until visuals are captured or provided. State this explicitly to the user when no automation succeeds — don't silently fall back to code-only review.
If the user declines to provide screenshots, run a code-only pass and clearly mark the report [CODE-ONLY REVIEW — visual issues not assessed] at the top so the limitation is explicit.
Note: audit is knob-agnostic — accessibility and performance are not tunable.
Scope (non-negotiable checks):
- Accessibility — read
references/accessibility.md:- Visible
:focus-visibleon every interactive element - Keyboard reachable, no focus traps
- Touch targets ≥ 44px (mobile)
- Color not the only signal for state
- Form labels, error association, required indication

- Visible
- Performance — read

- No horizontal scroll at 320px
Output format — the Review Format table from SKILL.md:
| Before | After | Why |
|---|
Group findings by priority: Critical (blocks usability/a11y) → High-impact (immediately noticeable) → Quick wins (polish).
Do NOT rewrite code unless asked. Report findings first; wait for approval before editing.
Close with a Craft Report (references/review.md → Craft Report), wrapping the findings table above — Checked states scope (a11y/perf/responsive, at which viewports), Passed carries anything inspected and found sound, Changed stays empty pre-approval, Verdict names the top priority. Produce it even on a clean audit — a11y/perf/responsive coming back clean is the finding.
Next step: /harden — turn the findings into real production coverage (rung 1).
