Does it support React-specific debugging?

Absolutely. It features native React DevTools support, allowing Claude to map DOM elements back to their respective React components for deeper inspection.

Why does this skill prefer ARIA snapshots over screenshots?

ARIA snapshots provide a semantic representation of the page structure, allowing the AI to understand element roles and labels more accurately than visual pixels, leading to more reliable automation.

Can I use this skill to debug network issues?

Yes, the skill includes capabilities to monitor HTTP requests, capture console messages, and analyze network performance to identify frontend bottlenecks.

How does the reference-based workflow improve stability?

It assigns unique IDs (like e1, e2) to elements found in a snapshot. These refs remain valid for interactions until the next navigation, preventing 'element not found' errors common with dynamic CSS selectors.
