Dev Server Verification with agent-browser

You MUST verify the dev server with agent-browser after starting it. Do not assume the page works just because the dev server process started. Many issues (blank pages, hydration errors, missing env vars, broken imports) are only visible in the browser. Run this verification before continuing with any other work:

Quick Verification Flow

# 1. Open the dev server
agent-browser open http://localhost:3000
agent-browser wait --load networkidle

# 2. Screenshot for visual check
agent-browser screenshot --annotate

# 3. Check for errors
agent-browser eval 'JSON.stringify(window.__consoleErrors || [])'

# 4. Snapshot interactive elements
agent-browser snapshot -i
