+## Logic
+
+1. Execute: `npx playwright test [test_file]`
+2. If Success:
+   - Report success.
+   - Exit.
+3. If Failure:
+   - Capture output.
+   - Pass logs to @tester agent.
+   - @tester analyzes error and edits file.
+   - Repeat until success or max_retries reached.
+
+## Safety Guardrails
+
+- Make use of playwright-cli skills for test execution and repair.
+- Max Retries: 3 per file.
+- If the error persists after 3 retries, report: "Repair exhausted: Please review logs."
