SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill bridges the gap between code changes and runtime reality, ensuring that your Next.js application behaves as expected in the browser rather than just passing compilation checks.

Core Features & Use Cases

Runtime Verification: Cross-references Next.js internal state via the MCP endpoint with real-time browser behavior using agent-browser.
Error Detection: Identifies compilation issues, server-side errors, and client-side browser failures in a unified workflow.
Use Case: After refactoring a complex React component, use this skill to confirm that the server-side rendering, client-side hydration, and UI interactions all function correctly without extra renders or broken routes.

Quick Start

Run the next-dev-loop skill to verify the current application state and confirm that your latest code changes are working correctly in the browser.

FAQPage Schema

How do I verify Next.js runtime behavior after making code edits?▼

Verify Next.js runtime behavior by synchronizing internal framework diagnostics with external browser-based interaction testing. This skill operates within a live development server to validate routes, server actions, and component rendering.

Why does my Next.js app compile successfully but break during client-side hydration?▼

Compilation checks do not guarantee correct runtime behavior. Client-side hydration breaks can occur due to mismatches between server-side rendering and client execution, requiring cross-view validation to detect.

Do I need Turbopack to test server actions in a live development server?▼

Yes, testing server actions and runtime behavior with this workflow requires Next.js 16.3+ with Turbopack enabled, alongside a configured agent-browser session to perform the cross-view validation.

How do I detect both server-side errors and client-side browser failures in Next.js?▼

Detect both server-side and client-side errors by cross-referencing Next.js internal state via the MCP endpoint with real-time browser behavior using agent-browser in a unified workflow.

What is the best way to validate component rendering after refactoring a Next.js route?▼

The best way to validate component rendering is to cross-reference Next.js internal framework diagnostics with real-time browser interactions, confirming server-side rendering and UI interactions function correctly.

Can I use this skill to check for broken routes without an agent-browser session?▼

No, you cannot validate broken routes without an agent-browser session. The skill requires a configured agent-browser session to perform the external interaction testing needed for cross-view validation.
