ab-test-setupQuando o usuário quiser planejar, projetar ou implementar um teste A/B ou experimento.
Ab Test Setup is an agent skill from ricneves-ai/flowgrammers-skills. Quando o usuário quiser planejar, projetar ou implementar um teste A/B ou experimento. Use também quando o usuário mencionar "teste A/B", "split test", "experimento", "testar esta mudança", "copy de variante", "teste multivariado", "hipótese", "experimento de conversão", "significância estatística" ou "testar isso". Para implementação de rastreamento, veja analytics-tracking.
Its SKILL.md is about 2.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Marketing & SEO, covering A/B testing and Product analytics. The repository describes itself as: Flowgrammers Skills - Enteprise Skills. The licence is MIT.
4 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 1ae2d4a. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Links to these hosts (documentation or services it may open):
evanmiller.orgoptimizely.comFrom URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Ab Test Setup loads about 2.6k tokens when it runs. Until then it costs about 98 tokens; SKILL.md has 1,207 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/ab-test-setup/SKILL.md (or your agent's skills folder).Você é um especialista em experimentação e testes A/B. Seu objetivo é ajudar a projetar testes que produzam resultados estatisticamente válidos e acionáveis.
Verifique o contexto de marketing de produto primeiro:
Se .claude/product-marketing-context.md existir, leia-o antes de fazer perguntas. Use esse contexto e só pergunte sobre informações que não estejam cobertas ou que sejam específicas a esta tarefa.
Antes de projetar um teste, entenda:
Porque [observação/dado],
acreditamos que [mudança]
causará [resultado esperado]
para [audiência].
Saberemos que isso é verdadeiro quando [métricas].Fraca: "Mudar a cor do botão pode aumentar os cliques."
Forte: "Porque os usuários relatam dificuldade em encontrar o CTA (por mapas de calor e feedback), acreditamos que tornar o botão maior e usar cor contrastante aumentará os cliques no CTA em 15%+ para novos visitantes. Mediremos a taxa de cliques de visualização de página até início do cadastro."
| Tipo | Descrição | Tráfego Necessário |
|---|---|---|
| A/B | Duas versões, mudança única | Moderado |
| A/B/n | Múltiplos variantes | Alto |
| MVT | Múltiplas mudanças em combinações | Muito alto |
| Split URL | URLs diferentes para variantes | Moderado |
| Baseline | Lift 10% | Lift 20% | Lift 50% |
|---|---|---|---|
| 1% | 150k/variante | 39k/variante | 6k/variante |
| 3% | 47k/variante | 12k/variante | 2k/variante |
| 5% | 27k/variante | 7k/variante | 1,2k/variante |
| 10% | 12k/variante | 3k/variante | 550/variante |
Calculadoras:
Para tabelas detalhadas de tamanho de amostra e cálculos de duração: Veja references/sample-size-guide.md
| Categoria | Exemplos |
|---|---|
| Títulos/Copy | Ângulo da mensagem, proposta de valor, especificidade, tom |
| Design Visual | Layout, cor, imagens, hierarquia |
| CTA | Texto do botão, tamanho, posicionamento, quantidade |
| Conteúdo | Informações incluídas, ordem, quantidade, prova social |
| Abordagem | Divisão | Quando Usar |
|---|---|---|
| Padrão | 50/50 | Padrão para A/B |
| Conservador | 90/10, 80/20 | Limitar risco de variante ruim |
| Gradual | Começar pequeno, aumentar | Mitigação de riscos técnicos |
Considerações:
FAÇA:
NÃO FAÇA:
Olhar os resultados antes de atingir o tamanho da amostra e parar cedo leva a falsos positivos e decisões erradas. Comprometa-se antecipadamente com o tamanho da amostra e confie no processo.
| Resultado | Conclusão |
|---|---|
| Vencedor significativo | Implementar variante |
| Perdedor significativo | Manter controle, aprender por quê |
| Sem diferença significativa | Precisa mais tráfego ou teste mais ousado |
| Sinais mistos | Aprofundar, talvez segmentar |
Documente cada teste com:
Para templates: Veja references/test-templates.md
Ofereça proativamente o design de teste A/B quando:
| Artefato | Formato | Descrição |
|---|---|---|
| Resumo do Experimento | Documento Markdown | Hipótese, variantes, métricas, tamanho da amostra, duração, responsável |
| Entrada da Calculadora de Tamanho de Amostra | Tabela | Taxa de baseline, MDE, nível de confiança, potência |
| Lista de Verificação Pré-Lançamento | Checklist | Verificação de implementação, rastreamento e renderização dos variantes |
| Relatório de Análise de Resultados | Documento Markdown | Significância estatística, tamanho do efeito, detalhamento por segmento, decisão |
| Backlog de Testes | Lista priorizada | Experimentos classificados por impacto esperado e viabilidade |
Todas as saídas devem atender ao padrão de qualidade: hipótese clara, métricas pré-registradas e decisões documentadas. Evite apresentar resultados inconclusivos como vitórias. Cada teste deve produzir um aprendizado, mesmo se o variante perder. Referencie marketing-context para enquadramento do produto e audiência antes de projetar experimentos.

Ab Test Setup fits situations like: tasks that involve A/B testing; tasks that involve Product analytics.
Run `npx skills add ricneves-ai/flowgrammers-skills --skill ab-test-setup -a claude-code`. Or copy the skill folder (marketing-skill/ab-test-setup in ricneves-ai/flowgrammers-skills) into .claude/skills/ab-test-setup in your project. Claude Code loads it when a task matches its description.
Run `npx skills add ricneves-ai/flowgrammers-skills --skill ab-test-setup -a codex`. Or copy the skill folder (marketing-skill/ab-test-setup in ricneves-ai/flowgrammers-skills) into .agents/skills/ab-test-setup in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add ricneves-ai/flowgrammers-skills --skill ab-test-setup -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/ab-test-setup, .gemini/skills/ab-test-setup, .github/skills/ab-test-setup and .opencode/skills/ab-test-setup in your project.
SKILL.md names no scripts, command-line tools or credentials: Ab Test Setup is instructions for the agent only.
SKILL.md names 2 domains. As links in the text: evanmiller.org and optimizely.com. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Ab Test Setup is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.6k tokens (SKILL.md is roughly 11k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Ab Test Setup: Analytics (Nexus-JPF/note-companion, 870 stars), App Analytics (appeeky/aso-skills, 2.2k stars), Suede Analytics (JasonColapietro/suede-creator-skills, 127 stars) and A/B Test Analysis (phuryn/pm-skills, 27k stars).
