Validate a product idea or feature before building it — 5 JTBD questions (customer's job, current workaround, why switch, adoption barriers, success metric), then a readiness score with risks and a next step. Use when an idea already exists and the question is whether it is worth building: «стоит ли делать», «нужна ли эта фича», «проверь идею», «есть идея — оцени», «а что если добавить», «имеет смысл?», «зайдёт ли», «оценить гипотезу», «валидировать идею», validate this idea, is this worth…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Проверка продуктового решения

Дешёвый способ убить слабую гипотезу до того, как в неё вложены дни.
Пять вопросов по JTBD (Jobs to be Done) + честная оценка готовности.

Связано с правилом «убийственный тест до стройки»: гипотезу дешевле проверить
разговором, чем инфраструктурой.

---

## Фаза 1 — Собрать ответы

Задай пользователю **пять вопросов через `AskUserQuestion`**. Инструмент берёт
не больше четырёх вопросов за вызов: вопросы 1–4 одним вызовом, 5 — вторым.
Формат вопроса — свободный текст, поэтому давай варианты как подсказки-заготовки,
а не как закрытый выбор.

Если пользователь уже рассказал часть в разговоре — **не переспрашивай**,
подставь известное и покажи, что ты понял, для подтверждения.

**Пропущенный вопрос — тоже информация.** Не блокируй процесс, помечай как
«не ответили» и учитывай в оценке.

### Вопрос 1. Какую задачу решает клиент?

Кто этот человек, что хочет сделать, зачем. И откуда ты это знаешь: проверено на
клиентах, гипотеза, или пока не знаешь.

- Сильно: «Руководитель отдела продаж хочет видеть конверсию по менеджерам в
  реальном времени, чтобы перераспределять лиды в течение дня. Проверено на 5 интервью.»
- Слабо: «Клиенты хотят аналитику.»

How to install

The exact contents, by fingerprint
mdr add gurudevvv/my-claude-skills/product-check@sha256:4a56ed0f870b6de2

The line at the top of this page pins the label git:20261002.a76280b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
