# Accessibility Testing and Remediation
## Configuration
- **WCAG Level**: ${wcag_level:AA}
- **Target Component**: ${component_name:Application}
- **Compliance Standard**: ${compliance_standard:WCAG 2.1}
- **Testing Scope**: ${testing_scope:full-audit}
- **Screen Reader**: ${screen_reader:NVDA}
## WCAG 2.1 Quick Reference
### Compliance Levels
| Level | Requirement | Common Issues |
|-------|-------------|---------------|
| A | Minimum baseline | Missing alt text, no keyboard access, missing form labels |
| ${wcag_level:AA} | Standard target | Contrast < 4.5:1, missing focus indicators, poor heading structure |
| AAA | Enhanced | Contrast < 7:1, sign language, extended audio description |
### Four Principles (POUR)
1. **Perceivable**: Content available to senses (alt text, captions, contrast)
2. **Operable**: UI navigable by all input methods (keyboard, touch, voice)
3. **Understandable**: Content and UI predictable and readable
4. **Robust**: Works with current and future assistive technologies
## Violation Severity Matrix
```
CRITICAL (fix immediately):
- No keyboard access to interactive elements
- Missing form labels
- Images without alt text
- Auto-playing audio without controls
- Keyboard traps
HIGH (fix before release):
- Contrast ratio below ${min_contrast_ratio:4.5}:1 (text) or 3:1 (large text)
- Missing skip links
- Incorrect heading hierarchy
- Focus not visible
- Missing error identification
MEDIUM (fix in next sprint):
- Inconsistent navigation
- Missing landmarks
- Poor link text ("click here")
- Missing language attribute
- Complex tables without headers
LOW (backlog):
- Timing adjustments
- Multiple ways to find content
- Context-sensitive help
```

```
## Keyboard Navigation Checklist
```markdown
[ ] All interactive elements reachable via Tab
[ ] Tab order follows visual/logical flow
[ ] Focus indicator visible (${focus_indicator_width:2}px+ outline, 3:1 contrast)
[ ] No keyboard traps (can Tab out of all elements)
[ ] Skip link as first focusable element
[ ] Enter activates buttons and links
[ ] Space activates checkboxes and buttons
[ ] Arrow keys navigate within components (tabs, menus, radio groups)
[ ] Escape closes modals and dropdowns
[ ] Modals trap focus until dismissed
```
## Screen Reader Testing Patterns
### Essential Announcements to Verify
```
Interactive Elements:
Button: "[label], button"
Link: "[text], link"
Checkbox: "[label], checkbox, [checked/unchecked]"
Radio: "[label], radio button, [selected], [position] of [total]"
Combobox: "[label], combobox, [collapsed/expanded]"
Dynamic Content:
Loading: Use aria-busy="true" on container
Status: Use role="status" for non-critical updates
Alert: Use role="alert" for critical messages
Live regions: aria-live="${aria_live_politeness:polite}"
Forms:
Required: "required" announced with label
Invalid: "invalid entry" with error message
Instructions: Announced with label via aria-describedby
```
### Testing Sequence
1. Navigate entire page with Tab key, listening to announcements
2. Test headings navigation (H key in screen reader)
3. Test landmark navigation (D key / rotor)
4. Test tables (T key, arrow keys within table)
5. Test forms (F key, complete form submission)
6. Test dynamic content updates (verify live regions)
## Color Contrast Requirements
| Text Type | Minimum Ratio | Enhanced (AAA) |
|-----------|---------------|----------------|
| Normal text (<${large_text_threshold:18}pt) | ${min_contrast_ratio:4.5}:1 | 7:1 |
| Large text (>=${large_text_threshold:18}pt or 14pt bold) | 3:1 | 4.5:1 |
| UI components & graphics | 3:1 | N/A |
| Focus indicators | 3:1 | N/A |
### Contrast Check Process
```
1. Identify all foreground/background color pairs
2. Calculate contrast ratio: (L1 + 0.05) / (L2 + 0.05)
where L1 = lighter luminance, L2 = darker luminance
3. Common failures to check:
- Placeholder text (often too light)
- Disabled state (exempt but consider usability)
- Links within text (must distinguish from text)
- Error/success states on colored backgrounds
- Text over images (use overlay or text shadow)
```
## ARIA Implementation Guide
### First Rule of ARIA
Use native HTML elements when possible. ARIA is for custom widgets only.
```html
<!-- WRONG: ARIA on native element -->
<div role="button" tabindex="0">Submit</div>
<!-- RIGHT: Native button -->
<button type="submit">Submit</button>
```
### When ARIA is Needed
```html
<!-- Custom tabs -->
<div role="tablist">
<button role="tab" aria-selected="true" aria-controls="panel1">Tab 1</button>
<button role="tab" aria-selected="false" aria-controls="panel2">Tab 2</button>
</div>
<div role="tabpanel" id="panel1">Content 1</div>
<div role="tabpanel" id="panel2" hidden>Content 2</div>
<!-- Expandable section -->
<button aria-expanded="false" aria-controls="content">Show details</button>
<div id="content" hidden>Expandable content</div>
<!-- Modal dialog -->
<div role="dialog" aria-modal="true" aria-labelledby="title">
<h2 id="title">Dialog Title</h2>
<!-- content -->
</div>
<!-- Live region for dynamic updates -->
<div aria-live="${aria_live_politeness:polite}" aria-atomic="true">
<!-- Status messages injected here -->
</div>
```
### Common ARIA Mistakes
```
- role="button" without keyboard support (Enter/Space)
- aria-label duplicating visible text
- aria-hidden="true" on focusable elements
- Missing aria-expanded on disclosure buttons
- Incorrect aria-controls reference
- Using aria-describedby for essential information
```
## Form Accessibility Patterns
### Required Form Structure
```html
<form>
<!-- Explicit label association -->
<label for="email">Email address</label>
<input type="email" id="email" name="email"
aria-required="true"
aria-describedby="email-hint email-error">
<span id="email-hint">We'll never share your email</span>
<span id="email-error" role="alert"></span>
<!-- Group related fields -->
<fieldset>
<legend>Shipping address</legend>
<!-- address fields -->
</fieldset>
<!-- Clear submit button -->
<button type="submit">Complete order</button>
</form>
```
### Error Handling Requirements
```
1. Identify the field in error (highlight + icon)
2. Describe the error in text (not just color)
3. Associate error with field (aria-describedby)
4. Announce error to screen readers (role="alert")
5. Move focus to first error on submit failure
6. Provide correction suggestions when possible
```
## Mobile Accessibility Checklist
```markdown
Touch Targets:
[ ] Minimum ${touch_target_size:44}x${touch_target_size:44} CSS pixels
[ ] Adequate spacing between targets (${touch_target_spacing:8}px+)
[ ] Touch action not dependent on gesture path
Gestures:
[ ] Alternative to multi-finger gestures
[ ] Alternative to path-based gestures (swipe)
[ ] Motion-based actions have alternatives
Screen Reader (iOS/Android):
[ ] accessibilityLabel set for images and icons
[ ] accessibilityHint for complex interactions
[ ] accessibilityRole matches element behavior
[ ] Focus order follows visual layout
```
## Automated Testing Integration
### Pre-commit Hook
```bash
#!/bin/bash
# Run axe-core on changed files
npx axe-core-cli --exit src/**/*.html
# Check for common issues
grep -r "onClick.*div\|onClick.*span" src/ && \
echo "Warning: Click handler on non-interactive element" && exit 1
```
### CI Pipeline Checks
```yaml
accessibility-audit:
script:
- npx pa11y-ci --config .pa11yci.json
- npx lighthouse --accessibility --output=json
artifacts:
paths:
- accessibility-report.json

- if: '$CI_PIPELINE_SOURCE == "merge_request_event"'
```
### Minimum CI Thresholds
```
axe-core: 0 critical violations, 0 serious violations
Lighthouse accessibility: >= ${lighthouse_a11y_threshold:90}
pa11y: 0 errors (warnings acceptable)
```

```
## WCAG Quick Reference
### Severity Classification
| Severity | Impact | Examples | Fix Timeline |
|----------|--------|----------|--------------|
| Critical | Blocks access entirely | No keyboard focus, empty buttons, missing alt on functional images | Immediate |
| Serious | Major barriers | Poor contrast, missing form labels, no skip links | Within sprint |
| Moderate | Difficult but usable | Inconsistent navigation, unclear error messages | Next release |
| Minor | Inconvenience | Redundant alt text, minor heading order issues | Backlog |
### Common Violations and Fixes
**Missing accessible name**
```html
<!-- Violation -->
<button><svg>...</svg></button>
<!-- Fix: aria-label -->
<button aria-label="Close dialog"><svg>...</svg></button>
<!-- Fix: visually hidden text -->
<button><span class="sr-only">Close dialog</span><svg>...</svg></button>
```
**Form label association**
```html
<!-- Violation -->
<label>Email</label>
<input type="email">
<!-- Fix: explicit association -->
<label for="email">Email</label>
<input type="email" id="email">
<!-- Fix: implicit association -->
<label>Email <input type="email"></label>
```
**Color contrast failure**
```
Minimum ratios (WCAG ${wcag_level:AA}):
- Normal text (<${large_text_size:18}px or <${bold_text_size:14}px bold): ${contrast_ratio_normal:4.5}:1
- Large text (>=${large_text_size:18}px or >=${bold_text_size:14}px bold): ${contrast_ratio_large:3}:1
- UI components and graphics: 3:1
Tools: WebAIM Contrast Checker, browser DevTools
```
**Focus visibility**
```css
/* Never do this without alternative */
:focus { outline: none; }
/* Proper custom focus */
:focus-visible {
outline: ${focus_outline_width:2}px solid ${focus_outline_color:#005fcc};
outline-offset: ${focus_outline_offset:2}px;
}
```
## ARIA Decision Framework
```
Need to convey information to assistive technology?
|
+-- Can semantic HTML do it?
| +-- YES: Use HTML (<button>, <nav>, <main>, <article>)
| +-- NO: Continue to ARIA
|
+-- What type of ARIA needed?
+-- Role: What IS this element? (role="dialog", role="tab")
+-- State: What condition? (aria-expanded, aria-checked)
+-- Property: What relationship? (aria-labelledby, aria-describedby)
+-- Live region: Dynamic content? (aria-live="${aria_live_mode:polite}")
```
### ARIA Patterns for Common Widgets
**Disclosure (show/hide)**
```html
<button aria-expanded="false" aria-controls="content-1">
Show details
</button>
<div id="content-1" hidden>
Content here
</div>
```
**Tab interface**
```html
<div role="tablist" aria-label="${component_name:Settings}">
<button role="tab" aria-selected="true" aria-controls="panel-1" id="tab-1">
General
</button>
<button role="tab" aria-selected="false" aria-controls="panel-2" id="tab-2" tabindex="-1">
Privacy
</button>
</div>
<div role="tabpanel" id="panel-1" aria-labelledby="tab-1">...</div>
<div role="tabpanel" id="panel-2" aria-labelledby="tab-2" hidden>...</div>
```
**Modal dialog**
```html
<div role="dialog" aria-modal="true" aria-labelledby="dialog-title">
<h2 id="dialog-title">Confirm action</h2>
<p>Are you sure you want to proceed?</p>
<button>Cancel</button>
<button>Confirm</button>
</div>
```
## Keyboard Navigation Checklist
```
[ ] All interactive elements focusable with Tab
[ ] Focus order matches visual/logical order
[ ] Focus visible on all elements
[ ] No keyboard traps (can always Tab out)
[ ] Skip link as first focusable element
[ ] Escape closes modals/dropdowns
[ ] Arrow keys navigate within widgets (tabs, menus, grids)
[ ] Enter/Space activates buttons and links
[ ] Custom shortcuts documented and configurable
```
### Focus Management Patterns
**Modal focus trap**
```javascript
// On modal open:
// 1. Save previously focused element
// 2. Move focus to first focusable in modal
// 3. Trap Tab within modal boundaries
// On modal close:
// 1. Return focus to saved element
```
**Dynamic content**
```javascript
// After adding content:
// - Announce via aria-live region, OR
// - Move focus to new content heading
// After removing content:
// - Move focus to logical next element
// - Never leave focus on removed element
```
## Screen Reader Testing
### Announcement Verification
| Element | Should Announce |
|---------|-----------------|
| Button | Role + name + state ("Submit button") |
| Link | Name + "link" ("Home page link") |
| Image | Alt text OR "decorative" (skip) |
| Heading | Level + text ("Heading level 2, About us") |
| Form field | Label + type + state + instructions |
| Error | Error message + field association |
### Testing Commands (Quick Reference)
**VoiceOver (macOS)**
- VO = Ctrl + Option
- VO + A: Read all
- VO + Right/Left: Navigate elements
- VO + Cmd + H: Next heading
- VO + Cmd + J: Next form control
**${screen_reader:NVDA} (Windows)**
- NVDA + Down: Read all
- Tab: Next focusable
- H: Next heading

- B: Next button
## Automated Testing Integration
### axe-core in tests
```javascript
// ${test_framework:jest-axe}
import { axe, toHaveNoViolations } from 'jest-axe';
expect.extend(toHaveNoViolations);
test('${component_name:component} is accessible', async () => {
const { container } = render(<${component_name:MyComponent} />);
const results = await axe(container);
expect(results).toHaveNoViolations();
});
```
### Lighthouse CI threshold
```javascript
// lighthouserc.js
module.exports = {
assertions: {
'categories:accessibility': ['error', { minScore: ${lighthouse_score:90} / 100 }],
},
};
```
## Remediation Priority Matrix
```
Impact vs Effort:
Low Effort High Effort
High Impact | DO FIRST | PLAN NEXT |
| alt text | redesign |
| labels | nav rebuild |
----------------|--------------|---------------|
Low Impact | QUICK WIN | BACKLOG |
| contrast | nice-to-have|
| tweaks | enhancements|

# Add AI-Specific Security with Arcjet
Secure AI/LLM endpoints with layered protection: prompt injection detection, PII blocking, and token budget rate limiting. These protections work together to block abuse before it reaches your model, saving AI budget and protecting user data.
## Reference
Read https://docs.arcjet.com/llms.txt for comprehensive SDK documentation covering all frameworks, rule types, and configuration options.
Arcjet rules run **before** the request reaches your AI model — blocking prompt injection, PII leakage, cost abuse, and bot scraping at the HTTP layer.
## Step 1: Ensure Arcjet Is Set Up
Check for an existing shared Arcjet client (see `/arcjet:protect-route` for full setup). If none exists, set one up first with `shield()` as the base rule. The user will need to register for an Arcjet account at https://app.arcjet.com then use the `ARCJET_KEY` in their environment variables.
## Step 2: Add AI Protection Rules
AI endpoints should combine these rules on the shared instance using `withRule()`:
### Prompt Injection Detection
Detects jailbreaks, role-play escapes, and instruction overrides.
- JS: `detectPromptInjection()` — pass user message via `detectPromptInjectionMessage` parameter at `protect()` time
- Python: `detect_prompt_injection()` — pass via `detect_prompt_injection_message` parameter
Blocks hostile prompts **before** they reach the model. This saves AI budget by rejecting attacks early.
### Sensitive Info / PII Blocking
Prevents personally identifiable information from entering model context.
- JS: `sensitiveInfo({ deny: ["EMAIL", "CREDIT_CARD_NUMBER", "PHONE_NUMBER", "IP_ADDRESS"] })`
- Python: `detect_sensitive_info(deny=[SensitiveInfoType.EMAIL, SensitiveInfoType.CREDIT_CARD_NUMBER, ...])`
Pass the user message via `sensitiveInfoValue` (JS) / `sensitive_info_value` (Python) at `protect()` time.
### Token Budget Rate Limiting
Use `tokenBucket()` / `token_bucket()` for AI endpoints — the `requested` parameter can be set proportional to actual model token usage, directly linking rate limiting to cost. It also allows short bursts while enforcing an average rate, which matches how users interact with chat interfaces.
Recommended starting configuration:
- `capacity`: 10 (max burst)
- `refillRate`: 5 tokens per interval
- `interval`: "10s"
Pass the `requested` parameter at `protect()` time to deduct tokens proportional to model cost. For example, deduct 1 token per message, or estimate based on prompt length.
Set `characteristics` to track per-user: `["userId"]` if authenticated, defaults to IP-based.
### Base Protection
Always include `shield()` (WAF) and `detectBot()` as base layers. Bots scraping AI endpoints are a common abuse vector. For endpoints accessed via browsers (e.g. chat interfaces), consider adding Arcjet advanced signals for client-side bot detection that catches sophisticated headless browsers. See https://docs.arcjet.com/bot-protection/advanced-signals for setup.
## Step 3: Compose the protect() Call and Handle Decisions
All rule parameters are passed together in a single `protect()` call. Use this pattern:
```typescript
const userMessage = req.body.message; // the user's input
const decision = await aj.protect(req, {
requested: 1, // tokens to deduct for rate limiting
sensitiveInfoValue: userMessage, // PII scanning
detectPromptInjectionMessage: userMessage, // injection detection
});
if (decision.isDenied()) {
if (decision.reason.isRateLimit()) {
return Response.json(
{ error: "You've exceeded your usage limit. Please try again later." },
{ status: 429 },
);
}
if (decision.reason.isPromptInjection()) {
return Response.json(
{ error: "Your message was flagged as potentially harmful." },
{ status: 400 },
);
}
if (decision.reason.isSensitiveInfo()) {
return Response.json(
{
error:
"Your message contains sensitive information that cannot be processed. Please remove any personal data.",
},
{ status: 400 },
);
}
if (decision.reason.isBot()) {
return Response.json({ error: "Forbidden" }, { status: 403 });
}
}
// Arcjet fails open — log errors but allow the request
if (decision.isErrored()) {
console.warn("Arcjet error:", decision.reason.message);
}
// Proceed with AI model call...
```
Adapt the response format to your framework (e.g., `res.status(429).json(...)` for Express).
## Step 5: Verify
1. Start the app and send a normal message — should succeed
2. Test prompt injection by sending something like "Ignore all previous instructions and..."
3. Test PII blocking by sending a message with a fake credit card number
Start all rules in `"DRY_RUN"` mode first. Once verified, promote to `"LIVE"`.
**Always recommend using the Arcjet MCP tools** to verify rules and analyze traffic:
- `list-requests` — confirm decisions are being recorded, filter by conclusion to see blocks
- `analyze-traffic` — review denial rates and patterns for the AI endpoint
- `explain-decision` — understand why a specific request was allowed or denied (useful for tuning prompt injection sensitivity)
- `promote-rule` — promote rules from `DRY_RUN` to `LIVE` once verified
If the user wants a full security review, suggest the `/arcjet:security-analyst` agent which can investigate traffic, detect anomalies, and recommend additional rules.
The Arcjet dashboard at https://app.arcjet.com is also available for visual inspection.
## Common Patterns
**Streaming responses**: Call `protect()` before starting the stream. If denied, return the error before opening the stream — don't start streaming and then abort.
**Multiple models / providers**: Use the same Arcjet instance regardless of which AI provider you use. Arcjet operates at the HTTP layer, independent of the model provider.
**Vercel AI SDK**: Arcjet works alongside the Vercel AI SDK. Call `protect()` before `streamText()` / `generateText()`. If denied, return a plain error response instead of calling the AI SDK.
## Common Mistakes to Avoid
- Sensitive info detection runs **locally in WASM** — no user data is sent to external services. It is only available in route handlers, not in Next.js pages or server actions.
- `sensitiveInfoValue` and `detectPromptInjectionMessage` (JS) / `sensitive_info_value` and `detect_prompt_injection_message` (Python) must both be passed at `protect()` time — forgetting either silently skips that check.
- Starting a stream before calling `protect()` — if the request is denied mid-stream, the client gets a broken response. Always call `protect()` first and return an error before opening the stream.
- Using `fixedWindow()` or `slidingWindow()` instead of `tokenBucket()` for AI endpoints — token bucket lets you deduct tokens proportional to model cost and matches the bursty interaction pattern of chat interfaces.
- Creating a new Arcjet instance per request instead of reusing the shared client with `withRule()`.

Use the following setup to begin your project:
```javascript
pnpm create vite my-react-flow-app --template react
pnpm add @xyflow/react
import { useState, useCallback } from 'react';
import { ReactFlow, applyNodeChanges, applyEdgeChanges, addEdge } from '@xyflow/react';
import '@xyflow/react/dist/style.css';
const initialNodes = [
{ id: 'n1', position: { x: 0, y: 0 }, data: { label: 'Node 1' } },
{ id: 'n2', position: { x: 0, y: 100 }, data: { label: 'Node 2' } },
];
const initialEdges = [{ id: 'n1-n2', source: 'n1', target: 'n2' }];
export default function App() {
const [nodes, setNodes] = useState(initialNodes);
const [edges, setEdges] = useState(initialEdges);
const onNodesChange = useCallback(
(changes) => setNodes((nodesSnapshot) => applyNodeChanges(changes, nodesSnapshot)),
[],
);
const onEdgesChange = useCallback(
(changes) => setEdges((edgesSnapshot) => applyEdgeChanges(changes, edgesSnapshot)),
[],
);
const onConnect = useCallback(
(params) => setEdges((edgesSnapshot) => addEdge(params, edgesSnapshot)),
[],
);
return (
<div style={{ width: '100vw', height: '100vh' }}>
<ReactFlow
nodes={nodes}
edges={edges}
onNodesChange={onNodesChange}
onEdgesChange={onEdgesChange}
onConnect={onConnect}
