Web Scanning
Supported Audit Methods
| Method | Tool | When to Use |
|---|---|---|
| Runtime scan | axe-core CLI | Live URL available (dev server or production) |
| Code review | Agent specialists | Source code available in workspace |
| Both | axe-core + agents | Most comprehensive – catches issues from both angles |
Runtime Scanning Commands
axe-core CLI
# Single page scan (WCAG 2.2 AA)
npx @axe-core/cli <URL> --tags wcag2a,wcag2aa,wcag21a,wcag21aa
# Save results to JSON
npx @axe-core/cli <URL> --tags wcag2a,wcag2aa,wcag21a,wcag21aa --save ACCESSIBILITY-SCAN.json
# Multiple pages
npx @axe-core/cli <URL1> <URL2> <URL3> --tags wcag2a,wcag2aa,wcag21a,wcag21aa --save ACCESSIBILITY-SCAN.json
# With Chrome flags (headless)
npx @axe-core/cli <URL> --tags wcag2a,wcag2aa,wcag21a,wcag21aa --chrome-flags="--headless --no-sandbox"
axe-core Tag Reference
| Tag | Standard |
|---|---|
| wcag2a | WCAG 2.0 Level A |
| wcag2aa | WCAG 2.0 Level AA |
| wcag21a | WCAG 2.1 Level A |
| wcag21aa | WCAG 2.1 Level AA |
| wcag22aa | WCAG 2.2 Level AA |
| best-practice | Best practices (not WCAG required) |
Screenshot Capture
capture-website-cli (preferred – lightweight)
# Full-page screenshot
npx capture-website-cli "<URL>" --output="screenshots/<page>.png" --full-page --type=png
# With viewport
npx capture-website-cli "<URL>" --output="screenshots/<page>.png" --full-page --width=1280 --height=720
# Mobile viewport
npx capture-website-cli "<URL>" --output="screenshots/<page>-mobile.png" --full-page --width=375 --height=812
# With delay for JS-rendered content
npx capture-website-cli "<URL>" --output="screenshots/<page>.png" --full-page --delay=3
Playwright (fallback)
npx playwright screenshot --browser chromium --full-page --wait-for-timeout 3000 "<URL>" "screenshots/<page>.png"
Page Discovery for Multi-Page Audits
Crawl Depth Modes
| Mode | Behavior | Max Pages |
|---|---|---|
| Current page only | Scan single URL | 1 |
| Key pages | User-provided list | User-defined |
| Full site crawl | Follow internal links | 50 (default cap) |
Sitemap-based Discovery
# Check for sitemap
curl -s <BASE_URL>/sitemap.xml | head -20
# Extract URLs from sitemap
curl -s <BASE_URL>/sitemap.xml | grep -oP '<loc>\K[^<]+' | head -50
Link-based Crawling
When crawling from a start URL:
- Follow only same-domain links
- Skip anchor links (#), mailto:, tel:, javascript: links
- Skip file downloads (.pdf, .zip, .doc, etc.)
- Respect robots.txt
- Cap at 50 pages unless user overrides
- Track visited URLs to avoid duplicates
Framework Detection
Detect the framework from workspace files to enable framework-specific scanning:
| Indicator | Framework |
|---|---|
package.json contains react |
React |
package.json contains next |
Next.js |
package.json contains vue |
Vue |
package.json contains @angular/core |
Angular |
package.json contains svelte |
Svelte |
.jsx / .tsx files present |
React/Next.js |
.vue files present |
Vue |
angular.json present |
Angular |
.svelte files present |
Svelte |
Only .html files |
Vanilla HTML |
Source Code File Patterns
When doing code review, scan these file patterns:
# HTML files
**/*.html
# Component files (framework-specific)
**/*.jsx
**/*.tsx
**/*.vue
**/*.svelte
**/*.component.ts
**/*.component.html
# Style files (for contrast/visual checks)
**/*.css
**/*.scss
**/*.less
**/*.module.css
# Config files (for framework detection)
package.json
next.config.*
nuxt.config.*
angular.json
svelte.config.*
tailwind.config.*
