deep-company-seriesPlans and writes a three-to-eight-part long-form article series that breaks down one company, built on fact-checked financials, valuation and management analysis.
The target is a public series, for channels such as WeChat, aimed at readers who want a textbook-level understanding of a company, with each article readable alone but sharing one view on valuation, management and price. The number of parts depends on complexity: seven or eight for a multi-business company with a large investment portfolio, four to six for a middle case, and three for a company with a clear core business, where the eight standard themes are folded into three articles but still all covered.
The skill sets research discipline: confirm today's date with the `date` command and state the data cutoff in the report header, cross-check financial data, use exact arithmetic tools such as `tools/financial_rigor.py` for valuation, and label uncertainty and source gaps. It is not for single research reports, earnings commentary or industry studies, which have their own commands. The text is in Chinese.
4 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit a221a20. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
gitpython3From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Deep Company Article Series loads about 2k tokens when it runs. Until then it costs about 27 tokens; SKILL.md has 727 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

参考样本:reports/腾讯/《看懂腾讯》/
用户希望为一家公司做"教科书级别"的深度研究,并以系列长文形式公开发布。区别于一篇研报:
不适合用本 skill 的场景:单篇研报、季报点评、行业研究——那些用 /investment-research、/earnings-review、/industry-research。
篇数不固定为 8。 8 篇是腾讯这种"多业务 + 万亿投资组合 + 20 年管理层故事"的公司才撑得起的容量。写之前先问:这家公司有几个能用"一个尖锐问题"独立成文的主轴?有几个写几篇。
| 复杂度 | 特征 | 篇数 | 例子 |
|---|---|---|---|
| 高 | 多条业务线各自成生意 + 隐藏资产/投资组合 + 管理层史料丰富 | 7-8 篇 | 腾讯 |
| 中 | 2-3 条业务线 + 一个重大时代变量 | 4-6 篇 | — |
| 低 | 主业清晰、核心问题少而集中 | 3 篇 | 快手 |
3 篇的标准合并方式(下面 8 主轴仍是检查清单,全部要覆盖,只是折进 3 篇):
| # | 篇名方向 | 折入的主轴 |
|---|---|---|
| 01 | 你以为你看懂了 X(开篇 + 生意与护城河) | 认知重置 + 护城河 + 利润引擎概览 |
| 02 | X 的最大变量(当下叙事/隐藏资产) | 隐藏资产 + AI/时代变量 |
| 03 | 多少钱值得买,什么信号必须卖(财务 + 决策终章) | 财务深度 + 管理层要点 + 估值决策 |
判断信号:如果某篇写到一半发现在"凑内容"(同一事实换说法重复出现),说明篇数定多了——合并。反之,某篇超过 12,000 字还塞不下,拆开。
| # | 篇名模板 | 核心问题 | 字数 |
|---|---|---|---|
| 01 | 你以为你看懂了 X,其实没有 | 认知重置:破 3 个常见错觉 | 4,000-5,000 |
| 02 | X 的护城河——<生意本质一句话> | 护城河深不深、未来 5/10 年还在不在 | 6,000-8,000 |
| 03 | X 的最大利润引擎——<最赚钱业务> | 主业是什么、为什么能持续 | 6,000-8,000 |
| 04 | X 藏在账上的另一家公司——<隐藏资产> | 投资组合 / 子公司 / 隐藏价值 | 8,000-10,000 |
| 05 | AI(或当下叙事)时代,X 是赢家还是输家 | 时代变量:分业务拆 AI 影响 | 8,000-10,000 |
| 06 | 用巴菲特方式拆 X 的财报 | 财务深度:毛利率/FCF/ROE/SBC | 8,000-10,000 |
| 07 | <管理层金句>——X 的管理层值不值得托付 | 资本配置纪律 + 诚信检验 + 接班人 | 8,000-10,000 |
| 08 | 多少钱值得买,什么信号必须卖(系列终章) | DCF 三情景 + 红线清单 + 仓位框架 | 10,000-12,000 |
加一篇 00-系列说明.md 作为目录索引,不发表。
篇目必须适配公司:模板是腾讯长出来的,不是套子。某篇没有独立内容(如没有投资组合的公司写不了 04),就替换成该公司特有的主轴(如快手的可灵 AI、电商),或按上面的合并方式折进更少的篇数。判断标准:这一篇能否用"一个尖锐问题"独立成文。
每篇不是自由发挥,有固定骨架。共性结构:
> 《看懂X》系列 · 第 0N 篇 · <主轴>,开篇加阅读时间## 本篇要点回顾(5-8 条,数字与正文严格一致)+ ## 下期预告(用尖锐问题预告,不剧透结论)*本文是《看懂X》系列第 0N 篇...* + *本系列基于公开信息和价值投资框架研究,不构成任何投资建议。*各篇专属骨架:
| 篇 | 骨架 |

| 02 护城河 | 挑战者失败名单(有名有姓有年份)→ 迁移成本的本质(用户迁不走什么)→ 生态飞轮 → 5 年/10 年后护城河还在吗 → 一个反向思维实验("如果我有 1000 亿能不能复制它") |
| 03 利润引擎 | 反常识数字开场 → 核心产品为何长青(拆到定价权层面)→ 增长空间量化(份额路径 + 反面论据:故事不工作的可能)→ 组织能力(为什么能持续出产品)→ 市场为什么低估 → AI/时代变量对本业务的影响 → 5 年后图景 |
| 04 隐藏资产 | TOP 持仓表(只统计未并表部分,并表的单独说明防双算)→ 会计处理差异(哪些进利润表哪些不进)→ "不会卖 vs 可能减持"分类 → 市场为何打折价(逐条)→ 几个意外发现 → 估算折扣的简单方法 |
| 05 AI/时代变量 | 让市场担心的数字 → 分业务拆赢家/输家(严重分化,不给整体结论)→ 关键反问("X 输了单点之争,还能赢吗")→ 5-10 年被绕过的场景推演(逐条反驳或承认)→ 5 个情景 → 未来一年监控信号清单 |
| 06 财务 | 一条反常曲线开场 → 利润表(毛利率变化归因)→ 口径选择(Non-IFRS vs GAAP,为什么)→ EPS 与回购 → 资产负债表(净现金)→ 现金流与 FCF Yield → 股东回报按"1 美元测试"→ ROE 变化是好是坏 → 估值横向+历史比较 → 价值投资 10 项 Checklist 逐条过 → 把财报压缩成三句话 |
| 07 管理层 | 核心团队表 → 关键人物的长期贡献(用具体决策,不用形容词)→ 利益对齐(持股/薪酬占利润比)→ 诚信检验:挑一次真实危机看应对 → 5 年承诺兑现率(逐条核对当年原话)→ 资本配置纪律 → 接班人隐忧(不回避)→ "买人三问"(诚实/能干/热爱)→ 综合评分 |
| 08 决策 | SOTP 分部估值(说清"你买的到底是什么")→ 历史估值分位 + 必须警告"后视镜不是导航仪" → 未来利润三情景表(乐观/中性/保守 + 隐含增速,标明"是预测不是事实")→ 红线清单(触发≠必卖,但必须重审)→ 赔率思维收尾 |

用户给修订意见时,按以下顺序处理:
如果用户说"X 数据不对",先用 Bash/Read 找原始数据交叉验证:
| 级别 | 类型 | 处理 |
|---|---|---|
| 🔥 硬错误 | 数字错、归因错、口径错 | 必改,不需犹豫 |
| ⚠️ 主观化 | 强主观词、绝对化、流量党比喻 | 弱化或删除 |
| 🔬 颗粒度 | 来源标注、口径细化 | 优先级低,按可读性平衡 |
| ❓ 不可靠 | 第三方测算差异大 | 删比改更稳(用户明确指示) |
修一处先想"哪些地方还会引用这个数字/概念"。例:
推送成功(commit hash)。

- 还有什么没改
下一步等指示。/Users/ / 真实姓名 等隐私字段写《看懂 X 系列》的核心能力 ≠ 写得好,而是改得严—— 89% 的财经长文死于伪精确数字、主观加权期望值、绝对化表述。本 skill 的存在就是为了把这些坑全部标记出来,写之前避开,写之后扫干净。

Deep Company Article Series fits situations like: writing a multi-part public deep dive on a single company; deciding how many articles a company's complexity justifies; fact-checking and cross-validating financial claims before publishing.
Run `npx skills add xbtlin/ai-berkshire --skill deep-company-series -a claude-code`. Or copy the skill folder (codex-skills/deep-company-series in xbtlin/ai-berkshire) into .claude/skills/deep-company-series in your project. Claude Code loads it when a task matches its description.
Run `npx skills add xbtlin/ai-berkshire --skill deep-company-series -a codex`. Or copy the skill folder (codex-skills/deep-company-series in xbtlin/ai-berkshire) into .agents/skills/deep-company-series in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add xbtlin/ai-berkshire --skill deep-company-series -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/deep-company-series, .gemini/skills/deep-company-series, .github/skills/deep-company-series and .opencode/skills/deep-company-series in your project.
Going by SKILL.md and its folder, Deep Company Article Series needs the command-line tools its instructions call (git and python3). Our summary lists: The ai-berkshire repository's `tools/` folder, such as `financial_rigor.py`; Python 3; Web search, for current financial data.
SKILL.md contains no URLs. Its commands use git, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Deep Company Article Series is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2k tokens (SKILL.md is roughly 8.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
