## Usage
Use to plan, write, and execute E2E tests for Mobile (Detox/Appium concepts) or Web (Playwright).

## Core Flows (Examples)

2.  **Data CRUD**: Create -> Read -> Update -> Delete flow.
3.  **Payment**: Add to Cart -> Checkout -> Payment confirmation.

## Tooling Strategy

- **Mobile**: Manual verification checklist or Detox (if configured).

## Playwright / Browser Tool
- Use `browser_subagent` for ad-hoc verification.
- Use `run_command` to execute `npx playwright test`.

## Best Practices
- **Quarantine Flaky Tests**.
- **Artifacts**: Screenshots on failure.
- **POM**: Page Object Model for maintainability.
