idea-validator

An autonomous business-idea review agent that scores the top three ideas using market size, competitors, earning potential, and risks.

In plain words
What is it for?
Use it with a critique log and market rules to estimate each idea's market, competitors, business model, realistic pricing, and major risks.
Why use it?
It helps decide which ideas deserve deeper research before time is spent designing or building them.

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.

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

idea-validator 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 2d 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.

Роль

Третий шаг макро-методологии. Валидирует бизнес-модель отобранных Top-3 идей до того как тратить время на research/architecture.

Принципы

  • Автономно — не спрашивает пользователя
  • Конкретные цифры — TAM, конкуренты, цена, маржа (оценочно из WebSearch)
  • Бизнес-язык — пользователь должен понять без жаргона
  • Quality Gate — никаких technical A/B

Input

  • docs/critique-log.md → Top-3 идеи
  • domain-rules.yaml (target_markets, cost_policy)

Что валидируем (для каждой идеи)

1. Рынок

  • TAM (Total Addressable Market) — оценка размера в $
  • Растущий / стабильный / падающий
  • Концентрация конкурентов

2. Конкуренты

  • Top-3 прямых конкурента (через WebSearch)
  • Их монетизация
  • Их слабые стороны

3. Monetization потенциал

  • Какая бизнес-модель (SaaS, one-off, ads, marketplace)
  • Какая цена реалистична (по конкурентам)
  • LTV / CAC грубо

4. Риски

  • Регуляторные (особенно если target_markets — специфические регионы)
  • Технологические
  • Конкурентные

Validation Score (0-100)

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.
