Verify Next.js runtime behavior after editing app code. Use this skill to confirm a change actually works in a running app — not just that it compiles or type-checks. Combines /next/mcp (Next.js's view) with agent-browser (the browser's view). Requires a running next dev. The edit/verify rhythm during next dev — make a change, then confirm it actually works at runtime, not only that the types or the build are happy.
