Codex adapter note
This skill is generated from skills/investment-research.md so Claude Code and Codex users share one canonical workflow.
- Treat
$ARGUMENTSas the user's request in the current Codex thread. - When the source mentions Claude-only surfaces such as Task, Agent, WebSearch, Bash, Read, or Write, use the closest Codex capability available in this session: subagents when available, web search when needed, shell commands for local tools, and normal file edits for workspace files.
- Use shared project tools from
tools/in this repository. Prefer running commands from the repository root with paths likepython3 tools/financial_rigor.py ...; if the current thread starts outside the repo, locate the actual checkout path first instead of assuming a fixed home-directory path. - Before starting research, run the
datecommand to confirm today's date; treat it as the baseline for "latest" data and state the data cutoff date in the report header. Never assume the current date from training data. - Preserve the research quality rules from
AGENTS.md: cross-check financial data, use exact arithmetic tools for valuation/math, and clearly label uncertainty and source gaps.

研究框架
基于巴菲特、芒格、段永平、李录四位投资大师的方法论,按以下七个模块顺序执行研究:
前置步骤:AI研究偏见自觉(必须执行)
在开始研究前,先评估该公司的"AI可研究性",识别潜在的数据偏见:
信息丰富度评级:
| 等级 | 特征 | AI研究陷阱 | 应对策略 |
|---|---|---|---|
| A级(信息充裕) | 上市多年、券商覆盖多、媒体报道密集 | 共识过强,AI输出趋同于市场定价,alpha有限 | 重点做反面检验:聪明人为什么不买?被忽略的风险是什么? |
| B级(信息适中) | 上市1-3年、覆盖有限、部分数据需推算 | AI可能用"合理推测"填补空白,看起来完整实则虚假确定性 | 每个推算数据标注置信度,区分"有据推算"和"凭空填充" |
| C级(信息稀缺) | 刚上市/冷门股/新兴市场、几乎无覆盖 | AI会因资料不足而过度保守,误判为"看不清=不好" | 用第一性原理提问(见下方),从有限信息中提取商业本质 |
C级公司的第一性原理研究法: 当公开资料不足时,不要试图拼凑出"看起来完整"的报告,而是聚焦以下底层问题:
- 客户是谁?为什么付钱?有没有替代选择?
- 复购靠什么驱动?是习惯、锁定、还是持续创造新价值?
- 竞争对手拿100亿能复制这门生意吗?
- 管理层做过什么关键决策?这些决策反映了什么判断力和价值观?
