+## Contributing QA Documentation
+
+QA-related contributions should follow the same principles as other content types, with specific attention to quality standards.
+
+### Test Documentation
+
+- Add detailed test documentation to `Claude/rules/test-documentation.md`
+- Follow the standards for test case structure, execution reporting, and defect reporting
+- Ensure alignment with ISTQB best practices
+
+### Exploratory Testing
+
+- Contribute exploratory testing practices to `Claude/skills/exploratory-testing.md`
+- Include practical examples of charters, session reports, and techniques
+- Document integration with Agile workflows
+
+### Agent Integration
+
+- Reference the `qa-specialist` agent in relevant PR descriptions
+- Ensure new testing approaches complement existing automated testing strategies
+- Coordinate with existing skills like `test-automation` and `tdd-workflow`
+
 ## Pull Request Guidelines
 
 - **One logical change per PR** — separate unrelated additions into separate PRs.
 - **Fill in the PR template** — describe what you added, why it's useful, and how you tested it.
 - **Update the README** if you add a new agent, language rule set, or notable skill.
 - **Review your own diff** before requesting review — check for typos, formatting issues, and broken links.
+- **For QA-related contributions**, reference the relevant agents (qa-specialist), skills (exploratory-testing), and rules (test-documentation, testing) to ensure alignment with quality standards.

+// Example Playwright test
+import { test, expect } from '@playwright/test'
+
+test('user can complete registration', async ({ page }) => {
+  await page.goto('/register')
+
+  // Fill registration form
+  await page.locator('#email').fill('test@example.com')

+# Run mobile tests
+npm install wd
+cd /path/to/mobile-tests
+node test-login.js
+```
+
+```javascript
+// Example Appium test
+const wd = require('wd')
+const assert = require('assert')
+
+async function runTest() {
+  const driver = wd.promiseChainRemote('localhost', 4723)
+
+  const capabilities = {
+    platformName: 'Android',
+    deviceName: 'Pixel 4',
+    app: '/path/to/app.apk',
+    automationName: 'UiAutomator2'
+  }
+
+  await driver.init(capabilities)
+
+  // Test login functionality
+  await driver.elementById('email').sendKeys('test@example.com')
+  await driver.elementById('password').sendKeys('Test123!')
+  await driver.elementById('login-button').click()
+
+  // Verify login success
+  const welcomeText = await driver elementById('welcome-message').text()
+  assert.strictEqual(welcomeText, 'Welcome, Test User!')
+
+  await driver.quit()
+}
+
+runTest()
+```
+
+### Accessibility Testing
+
+```bash
+# Run accessibility audit
+npx axe-playwright --url https://example.com --output-format json --output-file axe-report.json
+
+# Generate HTML accessibility report
+npx axe-playwright --url https://example.com --reporter v2
+```
+
+```typescript
+// Example accessibility test with Playwright
+import { test, expect } from '@playwright/test'
+import { AccessibilityAudit } from 'axe-playwright'
+
+test('page meets accessibility standards', async ({ page }) => {
+  await page.goto('/checkout')
+
+  // Create accessibility audit
+  const audit = new AccessibilityAudit(page)
+  const results = await audit.analyze()
+
+  // Assert no violations
+  expect(results.violations.length).toBe(0)
+
+  // Log detailed results
+  if (results.violations.length > 0) {
+    console.log('Accessibility violations found:')
+    results.violations.forEach(violation => {
+      console.log(`- ${violation.id}: ${violation.help}`)

+
+### Performance Testing
+
+```bash
+# Run Lighthouse audit
+npx playwright lighthouse https://example.com --config=config/lighthouse.config.js --output=json --output-path=report.json
+
+# Generate HTML report
+npx playwright lighthouse https://example.com --output=html --output-path=report.html
+
+# Compare performance to baseline
+npx lighthouse-batch https://example.com --config=config/lighthouse.config.js --compare
+```
+
+```typescript
+// Example performance test
+import { test, expect } from '@playwright/test'
+
+const LighthouseThresholds = {
+  performance: 90,
+  accessibility: 95,
+  'best-practices': 90,
+  seo: 90,
+  pwa: 85
+}
+
+test('meets performance thresholds', async ({ page }) => {
+  // Generate Lighthouse report
+  const report = await page.evaluate(async () => {
+    const lighthouse = await import('lighthouse/lighthouse-core/fraggle-rock/api.js')
+    const config = await import('../../../config/lighthouse.config.js')
+
+    const lhr = await lighthouse.gatherRunner.run()
+    return lhr
+  })
+
+  // Verify performance metrics
+  Object.entries(LighthouseThresholds).forEach(([category, threshold]) => {
+    const score = report.categories[category].score * 100
+    expect(score).toBeGreaterThanOrEqual(threshold)
+  })
+
+  // Verify Core Web Vitals
+  const timingMetrics = report.audits['metrics']
+  expect(timingMetrics.details.items[0]['largest-contentful-paint']).toBeLessThan(2500)
+  expect(timingMetrics.details.items[0]['total-blocking-time']).toBeLessThan(200)
+  expect(timingMetrics.details.items[0]['cumulative-layout-shift']).toBeLessThan(0.1)

+
+## Testing Methodology
+
+### 1. Test Planning
+- Review requirements and user stories
+- Identify test scenarios and edge cases
+- Create test cases with expected outcomes
+- Prioritize test cases by risk and impact
+
+### 2. Test Design
+- Develop automated test scripts
+- Design manual test procedures
+- Create test data
+- Set up test environments
+
+### 3. Test Execution
+- Run automated test suite
+- Execute manual test cases
+- Perform exploratory testing
+- Document test results
+
+### 4. Defect Management
+- Report defects with detailed reproduction steps
+- Categorize by severity and priority
+- Track through resolution
+- Verify fixes
+
+### 5. Test Reporting
+- Generate test summary reports
+- Analyze metrics and trends
+- Provide quality assessment
+- Recommend improvements
+
+## Key Principles
+
+1. **Test Early, Test Often** — Integrate testing throughout the development lifecycle
+2. **Quality is Everyone's Responsibility** — Collaborate with developers and product
+3. **Automate the Boring Parts** — Focus automation on repetitive, high-value tests
+4. **Manual Testing for the Complex** — Use human judgment for usability and edge cases
+5. **Accessibility by Default** — Build inclusive experiences from the start
+6. **Performance as a Feature** — Treat speed and responsiveness as product requirements
+
+## Test Coverage Requirements

+| Test Type | Target | Notes |
+|---------|--------|-------|
+| Unit Tests | 80%+ | Code coverage for individual functions |
+| Integration Tests | 80%+ | Coverage for API endpoints and data flows |

+| Accessibility | Level AA | Meet WCAG 2.1 AA standards |
+| Performance | Passing | Lighthouse performance score > 90 |
+| Mobile | iOS & Android | Test on both platforms |
+
+## Success Metrics
+
+- All critical user journeys covered by automated tests
+- Zero P0/P1 bugs in production
+- Test suite execution time under 10 minutes

+**Remember**: Testing is not about finding bugs — it's about building confidence. Every test you write makes the product more reliable and the team more confident. Be thorough, be systematic, but also be pragmatic. Quality is a journey, not a destination.
