description	Use when validating web UI runtime behavior with browser automation, including JavaScript errors, console logs, and rendered DOM checks.

Playright

Use this skill when a user asks to verify that a web UI actually works in a browser (not just build-time checks).

Core Rules

• Prefer real browser runtime checks over static assumptions.
• Capture pageerror and console error output before reporting success.
• Assert key DOM elements after load.
• Verify HTTP status and basic route health.
• Report exact runtime failures and repro context.

Implementation Pattern

1. Launch headless browser.
2. Open target URL with timeout and networkidle.
3. Collect pageerror and console error events.
4. Assert critical UI selectors exist.
5. Return a compact JSON-style result summary.

Verification Checklist

• Page responds with HTTP 200.
• Browser title is as expected.
• Main UI landmarks are rendered.
• No unhandled JS runtime errors.
• No console error events (or errors are explicitly listed).
