founder-synthetic-research

founder-synthetic-research is a skill for Claude Code, Codex from fourierwang66666/f-founder. It costs 110 tokens per session (2,252 once invoked), scanned B, original, MIT.

An AI-based user-research process that creates simulated users from real Reddit user profiles and interviews them about a product idea.

In plain words
What is it for?
Use it to investigate customer problems, test product assumptions, conduct Mom Test-style interviews, and produce a structured research report.
Why use it?
It helps explore user needs and objections before building, while allowing simulated users to reject an idea or say that existing solutions are enough.

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 B, and why

founder-synthetic-research scanned grade B with 2 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 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/reddit-profile.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Synthetic Research — AI 合成用户调研

这个 skill 做什么

帮助产品经理通过 AI 合成用户进行需求调研。合成用户基于 Reddit 真人画像构建, 在性别、年龄、城市、收入、MBTI、星座等维度随机分布,通过 Mom Test 方法论深度访谈。

触发条件

  • 用户说"做用户调研"/"用户访谈"/"需求验证"/"synthetic research"
  • 用户描述一个产品想法并想了解目标用户痛点
  • 用户要求生成合成用户/虚拟用户

反讨好规则

合成用户调研的核心价值在于真实反馈,必须防止 AI 讨好 founder:

合成用户层面:

  • 合成用户必须能说"不需要"、"不会用"、"太贵了"、"现有方案够用了"
  • 不允许所有合成用户都表示支持——至少 30% 应该持保留或否定态度
  • 合成用户的回答必须基于 Reddit 语料中的真实行为模式,不能为了让 founder 高兴而编造正面反馈

分析报告层面:

  • 不美化调研结论("用户普遍感兴趣" → 如实报告多少人正面、多少人负面、多少人无感)
  • 不隐藏负面信号(如果多数合成用户表示不需要,这就是最重要的发现)
  • 不把"没有反对"当成"支持"——沉默不是验证
  • 方法论声明必须明确标注"这是 AI 合成调研,不能替代真实用户访谈"

四阶段流程

Phase 1: 画像构建(自动 + 用户审批)

Step 1.1: 产品分析

分析用户输入的产品描述,输出:

  1. 目标用户群关键词(英文,用于 Reddit 搜索)
  2. 相关 subreddit 列表 — 先查 config/subreddit-map.json,再用 AI 补充
  3. 5-8 个产品相关属性维度(例如:时区/团队规模/远程年限)
  4. 建议合成用户数量 N(根据产品复杂度,通常 6-10)

展示给用户确认(可修改 subreddit 列表、属性维度、用户数量)

Step 1.2: Reddit 语料采集

对每个确认的 subreddit 执行:

bash scripts/reddit-profile.sh <subreddit> "<query>" --limit 15 --time month

收集帖子和评论,重点关注:吐槽、求助、经验分享、替代方案对比。 同时加载 config/persona-pool.json 作为补充语料。

Step 1.3: 合成用户生成

为 N 个用户分别执行:

  1. 随机分配基础属性(确保整体均衡分布):

    • 性别:男/女 按约均衡比例
    • 年龄:18-55 岁分散分布
    • 城市:一线/二线/海外 混合
    • 收入:低/中/中高/高 分散
    • 教育:高中/本科/硕士/博士 分散
    • 职业:与产品领域相关但有差异
  2. 随机分配心理属性

    • MBTI:从 16 型中随机抽取(不重复优先),参考 config/mbti-profiles.json
    • 星座:从 12 宫中随机抽取
    • 表达风格:基于 MBTI + Reddit 语料推断

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.
