A due-diligence document reviewer for a data room, the shared online folder used during a business transaction. It extracts important issues by category and presents them as an internal memo.

In plain words

It is for reviewing data-room files, filtering findings by importance, organizing issues into internal categories, and preparing issue memoranda.
Why use it?

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

diligence-issue-extraction 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 12d 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.

Origin

This is a copy

92% identical to ai-tool-handoff — 207 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 188 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/diligence-issue-extraction

  1. 加载 ~/.claude/plugins/config/claude-for-legal/corporate-legal/CLAUDE.md + ~/.claude/plugins/config/claude-for-legal/corporate-legal/deals/[代码]/deal-context.md
  2. 使用以下工作流。
  3. 检查 ai-tool-handoff ——如果类别为大批量且已配置工具,先交接。
  4. 阅读文件,适用重要性过滤,按类别提取。
  5. 发现以内部备忘录格式呈现。同意事项交接给交割检查表。

事项上下文

事项上下文。 检查实务级 CLAUDE.md 中的 ## 事项工作区。如果 Enabled(企业法务用户的默认值),跳过本段其余内容——技能使用实务级上下文,事项机制不可见。如果已启用且无活跃事项,询问:"这是哪个事项?运行 /corporate-legal:matter-workspace switch <事项简称> 或说 实务级。"加载活跃事项的 matter.md 获取事项特定上下文和覆盖规则。输出写入事项文件夹 ~/.claude/plugins/config/claude-for-legal/corporate-legal/matters/<事项简称>/。除非 跨事项上下文,否则绝不读取其他事项的文件。


目的

数据室有2,000份文件。其中约30份对交易重要。本技能按 ~/.claude/plugins/config/claude-for-legal/corporate-legal/CLAUDE.md 中的尽调类别和重要性阈值审阅文件,提取问题,并以内部备忘录格式书写。

加载上下文

  • ~/.claude/plugins/config/claude-for-legal/corporate-legal/CLAUDE.md → 尽调结构(类别、重要性阈值)
  • ~/.claude/plugins/config/claude-for-legal/corporate-legal/CLAUDE.md → 问题备忘录格式(发现如何陈述)
  • ~/.claude/plugins/config/claude-for-legal/corporate-legal/deals/[代码]/deal-context.md → 交易特定阈值、数据室位置

如果 deal-context.md 不存在,询问这是哪个交易。

工作流

第1步:盘存数据室

如果数据室 MCP(数据室/飞书/坚果云)已连接,拉取索引。将数据室文件夹映射到尽调需求清单类别。标注缺口——需求清单类别中没有对应数据室内容的部分。

## 数据室盘存:[交易代码]

| 需求类别 | 数据室文件夹 | 文件数 | 状态 |
|---|---|---|---|
| 公司及组织 | /01-公司文件 | 45 | 已审查 |
| 重大合同 | /02-合同 | 312 | 进行中 |
| 知识产权 | /03-知识产权 | 89 | 未开始 |
| [等] | | | |

**缺口:** [没有数据室内容的需求类别——需发送后续请求]

第2步:适用重要性过滤

~/.claude/plugins/config/claude-for-legal/corporate-legal/CLAUDE.md / 交易上下文中的阈值。如果阈值说合同大于 ¥X,不要审查全部。

对合同具体而言:按标明金额(如在文件名/元数据中)或按对方当事人重要性排序。自上而下审查直到达到阈值或类别穷尽。

第3步:提取问题

对每份已读文件,按该类别下标准尽调关注点进行检查:

重大合同——标准提取项:

  • 控制权变更条款(是否被本次交易触发?是否需要对方同意?)
  • 合同转让限制(合同能否转移给买方?)
  • 独家性/竞业禁止(是否限制买方的业务?)
  • 最惠国待遇(定价约束)
  • 解除权(对方当事人是否会因交易而有权解除?)
  • 异常赔偿或责任承担

公司——标准提取项:

  • 股权结构准确性、未行权期权/认股权证
  • 交易所需的董事会同意要求
  • 股东协议限制(拖售权、随售权、优先购买权)
  • 子公司结构及关联方安排

知识产权——标准提取项:

  • 权利归属链条(发起人/员工的转让是否到位?)
  • 产品中的开源代码(公共版权风险)
  • 关键知识产权是许可还是自有
  • 未决或受威胁的知识产权诉讼
