Accessibility Review

Overview

This skill enables manual accessibility reviews of web content, components, and applications against WCAG 2.1/2.2 Level AA standards. Reviews focus on practical, modern accessibility requirements without being overly pedantic.

When to Use This Skill

Use this skill when the user asks questions like:

• "Is this accessible?"
• "Can you review the color contrast?"
• "Check this component for accessibility issues"
• "Does this meet accessibility standards?"
• Any request to review, check, or validate accessibility

Review Process

1. Identify the Target

Determine what needs to be reviewed:

• Specific component (button, form, modal, etc.)
• Full page or application
• Code file or set of files
• Design mockup or screenshot

2. Conduct Manual Review

Use the WCAG checklist in references/wcag-checklist.md to systematically review the target against modern accessibility standards.

Focus on the most common and impactful issues:

• Perceivable: Color contrast, text alternatives, semantic structure
• Operable: Keyboard navigation, focus management, interactive elements
• Understandable: Clear labels, error handling, consistent navigation
• Robust: Valid HTML, ARIA usage, compatibility

3. Prioritize Findings

Classify each issue as:

Critical - Blocks users from accessing core functionality:

• Missing alt text on meaningful images
• Non-keyboard accessible interactive elements
• Insufficient color contrast (below 4.5:1 for normal text, 3:1 for large text)
• Forms without proper labels
• Missing focus indicators
• Inaccessible modal/dialog patterns
• Auto-playing media without controls

Warning - Creates friction but doesn't fully block access:

• Suboptimal heading hierarchy (skipped levels)
• Missing ARIA landmarks
• Link text that's unclear out of context
• Redundant or unnecessary ARIA
• Touch targets smaller than 44x44px
• Missing skip links
• Non-descriptive error messages

4. Stepped Review (One Issue at a Time)

IMPORTANT: Do NOT present all findings at once. Review issues one at a time, waiting for user decision before proceeding.

4.1 Start with Overview

Begin by telling the user how many issues were found:

CopyFound [X] accessibility issues ([Y] critical, [Z] warnings).

Let's review them one at a time. I'll present each issue with a recommended fix, and you can decide to:
- **Fix** — I'll implement the change
- **Ignore** — Tell me why, and I'll note it

Starting with critical issues first.

4.2 Present Each Issue

For each issue, present ONE at a time using this format:

Copy───────────────────────────────────
Issue [1/X]: [Critical/Warning]
───────────────────────────────────

**Problem**: [Clear description of the issue]

**Location**: `file_path:line_number`
[Show the relevant code snippet]

**Impact**: [How this affects users — be specific about who and how]

**Recommended Fix**:
[Specific code change or approach]

───────────────────────────────────
Fix this issue, or ignore? (If ignoring, please share why)

4.3 Handle User Response

If user says "fix":

1. Implement the fix
2. Confirm: "Fixed. [Brief description of what changed]"
3. Move to next issue

If user says "ignore" with reason:

1. Acknowledge: "Noted — ignoring because: [their reason]"
2. Track the decision (see 4.4)
3. Move to next issue

If user says "ignore" without reason:

1. Ask: "Got it. Quick note on why? (Helps for future reference)"
2. Accept any response and move on

4.4 Track Decisions

Keep a running tally as you go through issues. After all issues are reviewed, present a summary.

5. Final Summary

After reviewing all issues, present a summary:

Copy## Accessibility Review Complete

**Reviewed**: [X] issues ([Y] critical, [Z] warnings)

### Fixed ([N])
- [Issue description] — `file:line`
- [Issue description] — `file:line`

### Ignored ([N])
- [Issue description] — Reason: [user's reason]
- [Issue description] — Reason: [user's reason]

### Remaining Concerns
[Any patterns noticed, suggestions for future, or issues that were ignored but warrant reconsideration]

Review Guidelines

Be Practical: Focus on issues that genuinely impact users. Modern WCAG 2.1/2.2 Level AA is the standard—avoid over-engineering or citing obscure edge cases.

Be Specific: Reference actual code locations using file_path:line_number format when possible.

Be Constructive: Provide actionable fixes, not just problems. Include code examples when helpful.

Consider Context: Some patterns may have accessibility trade-offs. Acknowledge these and suggest the most accessible approach for the use case.

Common Patterns to Check

Interactive Elements

• All interactive elements must be keyboard accessible (Enter/Space to activate)
• Focus must be visible with clear indicators
• Custom controls need proper ARIA roles and states

Forms

• All inputs must have associated labels (explicit or aria-label)
• Error messages must be programmatically associated with fields
• Required fields must be indicated clearly

Color and Contrast

• Text contrast: 4.5:1 minimum for normal text, 3:1 for large text (18pt+ or 14pt+ bold)
• UI components: 3:1 contrast for interactive elements and their states
• Don't rely on color alone to convey information

Images and Media

• Meaningful images need descriptive alt text
• Decorative images should have empty alt (alt="")
• Videos need captions, audio content needs transcripts

Structure

• Use semantic HTML (nav, main, article, etc.)
• Heading hierarchy should be logical (h1 → h2 → h3)
• ARIA landmarks help screen reader navigation
