E2E Validation for Frontend Modifications

Prerequisites

Requires Playwright MCP server. If the browser_navigate tool is unavailable, instruct the user to add it:

claude mcp add playwright -- npx @playwright/mcp@latest

Validation Steps

After completing frontend changes:

1. Build the CLI

pnpm build:cli

2. Start the dev server

cd examples/agent && node ../../packages/cli/dist/index.js dev

3. Verify server is running

   • URL: http://localhost:4111
   • Wait for the server to be ready before proceeding

4. Identify impacted routes

   • Routes are defined in packages/playground/src/App.tsx
   • Browse them ALL to verify behavior

5. Test with Playwright MCP

   • Use browser_navigate to visit each impacted route
   • Visually verify the changes render correctly
   • Test any interactive elements modified
   • Use browser_screenshot to capture results for the user
