 1. **Playwright E2E Tests (MANDATORY - Run First)**:
     - **Run**: `npx playwright test --project=chromium` from project root
+    - **No Truncation**: Never pipe output through `head`, `tail`, or other truncating commands. Playwright requires user input to quit when piped, causing hangs.
     - **Why First**: If the app is broken at E2E level, unit tests may need updates. Catch integration issues early.
     - **Scope**: Run tests relevant to modified features (e.g., `tests/manual-dns-provider.spec.ts`)
     - **On Failure**: Trace root cause through frontend → backend flow before proceeding

 3.  **Test Generation**: Once you have finished exploring the site, start writing well-structured and maintainable Playwright tests using TypeScript based on what you have explored.
 4.  **Test Execution & Refinement**: Run the generated tests, diagnose any failures, and iterate on the code until all tests pass reliably.
 5.  **Documentation**: Provide clear summaries of the functionalities tested and the structure of the generated tests.

+- **No Truncation**: Never pipe Playwright test output through `head`, `tail`, or other truncating commands. Playwright runs interactively and requires user input to quit when piped, causing the command to hang indefinitely.
+- **Full Output**: Always capture the complete test output to analyze failures accurately.
