Mission

Find 1-3 high-confidence UX / a11y issues that are genuinely impactful in this codebase.

Focus areas:

• Focus management (focus trap, focus return after modal close, inert / aria-hidden consistency)
• ARIA attributes on interactive elements (aria-label / aria-pressed / aria-expanded / role)
• Keyboard navigation (Tab order, Escape close, arrow-key nav inside menus)
• Color contrast against CSS variable themes (light / dark)
• Semantic HTML drift between similar components (e.g., Modal.tsx vs ConfirmModal.tsx, SnoozeModal.tsx vs FeedAddModal.tsx, ArticleHeaderShare vs ArticleHeaderEngagement)
• Skip-to-content link / aria-live announcement region coverage

Skip if

• Purely theoretical (no real user impact, e.g., a <span> that could be a <button> but is never reachable)
• Fix complexity > expected gain
• Already addressed in a recent commit

Use Serena tools first

Default to find_symbol / search_for_pattern / get_symbols_overview / find_referencing_symbols. Reach for Read only when inspecting a full file is necessary.

Reference canonical patterns

Check issue-handling skill's "Similar components" comparison pattern. When you find a pattern present in one component but missing in its sibling, cite both files. Canonical examples in this codebase:

• Modal.tsx — focus restore on close
• FocusModeOverlay.tsx — full-screen overlay with Escape close
• useMenuKeyboard.ts — portal menu keyboard nav
• A11yHelpers.tsx — skip link + aria-live region

Verify against real code

Before reporting, read the cited file at the cited line range and confirm the missing pattern is genuinely absent (not on a parent component or higher-order helper).

Report format

Under 400 words. Per finding:

### Finding N: <short title>

- **File**: `path/to/file.tsx:LINE` (or `LINE-LINE`)
- **Canonical**: `path/to/canonical.tsx:LINE` (sibling that does it right, if applicable)
- **Observation**: 1-2 sentences on what is missing
- **Impact**: WCAG criterion violated + which user class is affected (keyboard-only / screen-reader / low-vision)
- **Fix**: 1-2 sentences on the minimal correction
- **Confidence**: 0-100 (only report findings >= 75)

End with: total findings count, plus 1 sentence on whether the maintainer should adopt all, some, or escalate to Issue triage.
