Método para entrevistar clientes e testar uma ideia de negócio com base em fatos reais, e não em elogios ou promessas. O nome vem de uma comparação: até sua mãe pode dizer que uma ideia é boa para não contrariá-lo.

Serve para criar perguntas sobre experiências passadas, descobrir como alguém resolveu um problema e identificar sinais de interesse falso ou incerto.

Ajuda a evitar entrevistas que induzem respostas positivas e revelam pouco sobre problemas que as pessoas realmente enfrentam.

Per session 59 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

When invoked 483 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

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	$0.00059	$0.00483
Opus 5.5	$0.00024	$0.00193
Sonnet 5.5	$0.00012	$0.00097
Haiku 4.5	$0.00006	$0.00048

Measured 2mo ago against content hash ee977bc7cba7, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

mom-test 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 2mo 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.

What it actually says

The Mom Test — 客户访谈的正确姿势

你妈会对你说「这是个好主意」——不是因为她真这么想，是因为她爱你。不要问「你会买吗」——你会被撒谎。

Rob Fitzpatrick 教你做不被骗的客户访谈。

三条铁律

1. 谈论他们的生活，而不是你的想法

✘ 「如果我做一个 X 产品，你会用吗？」（诱导性问题）
✔ 「你最近一次遇到 Y 问题是什么时候？你怎么解决的？」

2. 问过去的具体事实，不问未来的假设意见

✘ 「你愿意付多少钱？」
✔ 「你上次为了解决这个问题花了多少钱？」

未来意见 = 假的。过去行为 = 真的。

3. 少说多听

你说的越多，他们越会附和。保持沉默，让他们填满空白。

四个危险信号

信号	他们说什么	真实含义
恭维	「这个想法挺好的」	我不想伤害你
假设	「我肯定会用」	我现在不会付钱
模糊	「可能以后会需要」	不需要
推荐	「你应该跟 XX 谈」	我不感兴趣，但不想拒绝你

一句话总结

客户访谈的目的不是确认你的想法是对的——是找出你的想法哪里错了。最好的问题都以「你上一次……」开头。

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.
