A migration guide for converting Cypress or Selenium tests to Playwright, a browser testing tool. It works through the test files and helps assess the size of the migration.

Use it to convert Cypress or Selenium test files, detect the existing framework, review custom commands and fixtures, and set up Playwright when needed.

Moving between browser testing tools often requires rewriting commands, fixtures, and setup by hand. This gives the work a defined process and identifies project-specific migration effort.

migrate — Skill for Claude Code by ricneves-ai

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add ricneves-ai/flowgrammers-skills --skill migrate

Clone the repo

git clone --depth 1 https://github.com/ricneves-ai/flowgrammers-skills

Made for: Claude Code.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00058	$0.01156
Opus 5	$0.00029	$0.00578
Sonnet 5	$0.00012	$0.00231
Haiku 4.5	$0.00006	$0.00116

Security

Grade A, and why

migrate 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 9d 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.

Migrar para o Playwright

Migração interativa do Cypress ou Selenium para o Playwright com conversão arquivo por arquivo.

Entrada

$ARGUMENTS pode ser:

"from cypress" — migrar suite de testes Cypress
"from selenium" — migrar testes Selenium/WebDriver
Um caminho de arquivo: converter um arquivo de teste específico
Vazio: detectar automaticamente o framework de origem

Passos

1. Detectar o Framework de Origem

Use o subagente Explore para escanear:

Diretório cypress/ ou cypress.config.ts → Cypress
selenium, webdriver nas dependências do package.json → Selenium
Arquivos .py com imports de selenium → Selenium (Python)

2. Avaliar o Escopo da Migração

Contar arquivos e categorizar:

Avaliação de Migração:
- Total de arquivos de teste: X
- Comandos customizados Cypress: Y
- Fixtures Cypress: Z
- Esforço estimado: [pequeno|médio|grande]

Tamanho	Arquivos	Abordagem
Pequeno (1-10)	Converter sequencialmente	Conversão direta
Médio (11-30)	Em lotes de 5	Usar subagentes
Grande (31+)	Usar `/batch`	Conversão paralela com `/batch`

3. Configurar Playwright (Se Não Estiver Presente)

Executar /pw:init primeiro se o Playwright não estiver configurado.

4. Converter Arquivos

Para cada arquivo, aplicar o mapeamento apropriado:

Cypress → Playwright

Traduções principais:

cy.visit(url)           → page.goto(url)
cy.get(selector)        → page.locator(selector) ou page.getByRole(...)
cy.contains(text)       → page.getByText(text)
cy.find(selector)       → locator.locator(selector)
cy.click()              → locator.click()
cy.type(text)           → locator.fill(text)
cy.should('be.visible') → expect(locator).toBeVisible()
cy.should('have.text')  → expect(locator).toHaveText(text)
cy.intercept()          → page.route()
cy.wait('@alias')       → page.waitForResponse()
cy.fixture()            → import JSON ou arquivo de dados de teste

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.
