A setup guide for Playwright, a tool that tests websites in real browsers. It detects the project setup and prepares browser tests, example tests, and continuous-integration configuration.

In plain words
What is it for?
Use it to add end-to-end tests that check complete user journeys in frameworks such as React, Next.js, Vue, Angular, or Svelte.
Why use it?
It removes the manual work of adding browser-testing tools and connecting them to an existing JavaScript or TypeScript project.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

init scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Inicializar Projeto Playwright

Configure um ambiente de testes Playwright pronto para produção. Detecte o framework, gere config, estrutura de pastas, teste de exemplo e pipeline de CI.

Passos

1. Analisar o Projeto

Use o subagente Explore para escanear o projeto:

  • Verificar package.json para identificar o framework (React, Next.js, Vue, Angular, Svelte)
  • Verificar se existe tsconfig.json → usar TypeScript; caso contrário, JavaScript
  • Verificar se o Playwright já está instalado (@playwright/test nas dependências)
  • Verificar diretórios de teste existentes (tests/, e2e/, __tests__/)
  • Verificar configuração de CI existente (.github/workflows/, .gitlab-ci.yml)

2. Instalar Playwright

Se ainda não estiver instalado:

npm init playwright@latest -- --quiet

Ou se o usuário preferir configuração manual:

npm install -D @playwright/test
npx playwright install --with-deps chromium

3. Gerar playwright.config.ts

Adaptar ao framework detectado:

Next.js:

import { defineConfig, devices } from '@playwright/test';

export default defineConfig({
  testDir: './e2e',
  fullyParallel: true,
  forbidOnly: !!process.env.CI,
  retries: process.env.CI ? 2 : 0,
  workers: process.env.CI ? 1 : undefined,
  reporter: [
    ['html', { open: 'never' }],
    ['list'],
  ],
  use: {
    baseURL: 'http://localhost:3000',
    trace: 'on-first-retry',
    screenshot: 'only-on-failure',
  },
  projects: [
    { name: "chromium", use: { ...devices['Desktop Chrome'] } },
    { name: "firefox", use: { ...devices['Desktop Firefox'] } },
    { name: "webkit", use: { ...devices['Desktop Safari'] } },
  ],
  webServer: {
    command: 'npm run dev',
    url: 'http://localhost:3000',
    reuseExistingServer: !process.env.CI,
  },
});

React (Vite):

  • Alterar baseURL para http://localhost:5173
  • Alterar webServer.command para npm run dev

Vue/Nuxt:

  • Alterar baseURL para http://localhost:3000
  • Alterar webServer.command para npm run dev

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
