What it does
Contract Review is an agent skill from open-octo/octo-agent. 审阅合同条款、识别风险点、给出修改建议。Use when 用户贴出或上传合同文本要求审查， 或提到"合同审查""帮我看看这份合同""这条款有没有问题""重大不利条款""合同风险" "review this contract"等。覆盖服务协议、劳动合同、保密协议(NDA)、采购合同、 租赁合同等常见合同类型，风险条款库为中英双语。仅做通俗的条款风险提示， 不构成正式法律意见——高价值/高风险合同仍需持证律师最终把关。
Its SKILL.md is about 670 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `PROVENANCE.md`).
It sits in Legal & Compliance, covering Contract review. The repository describes itself as: Open-source, single-binary, self-hosted AI agent — your models and data stay on your machine. A coding agent on par with Claude Code and a personal assistant lighter than… The licence is MIT.
When your agent uses it
- Tasks that involve Contract review
Example prompts
- “帮我看看这份合同”
- “这条款有没有问题”
- “重大不利条款”
- “/contract-review”
Requirements
- Python 3
What it can do on your machine
Read from SKILL.md and the folder at commit 81448b2. It shows what the files ask for, not the result of running them.
Tool permissions
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.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Contract Review loads about 666 tokens when it runs. Until then it costs about 56 tokens; SKILL.md has 113 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.
Safety
Auto-check passed
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.

Skill: contract-review
审阅一份合同：识别对用户不利的条款、检查该类合同该有却缺失的关键条款、给出具体 的修改建议。产出是一份结构化审查报告，不是"这份合同能不能签"的最终结论。
前置：合同不完整信息不硬编
只处理用户实际提供的合同文本。缺少的信息（准据法、双方主体资格、合同金额上下文 等）如果影响判断，明确列在报告的"需要澄清"部分，不要替用户假设或编造。
第一步：识别合同类型
先判断合同属于哪一类，决定后面用哪套"关键条款清单"核对完整性：
| 类型 | 关键条款清单 |
|---|---|
| 服务协议 | 服务范围、服务标准、付款、知识产权、保密 |
| 劳动合同 | 工作内容、薪酬福利、工作时间、竞业限制、解除条件 |
| 保密协议(NDA) | 保密信息定义、保密期限、例外情况、返还义务 |
| 采购合同 | 产品规格、交付、验收、质保、付款 |
| 租赁合同 | 租赁物、租金、期限、维护责任、解约条件 |
不属于以上五类的合同，仍套用通用的风险条款表（第二步），但完整性检查（第三步） 需要用户或常识补充该类合同的典型必备条款。
第二步：逐条对照风险条款表
通读合同全文，对每一条实质性条款检查是否命中下表任一风险模式。命中时，在报告里 引用原文（不要转述或凭印象复述条款内容），标注严重度，给出修改建议：
| 风险模式 | 严重度 | 说明 | 建议 |
|---|---|---|---|
| 无限责任 | 高 | 责任或赔偿义务没有上限 | 增加责任上限（如 12 个月费用或合同金额） |
| 宽泛知识产权转让 | 高 | 转让全部知识产权，包括合同前已有的知识产权 | 排除既有知识产权，明确转让范围 |
| 单方解约权 | 高 | 一方可无理由或极短通知期解约 | 要求双方对等的解约权或合理通知期 |
| 单向赔偿 | 高 | 只有一方承担赔偿/indemnification义务 | 争取双向赔偿或限定范围 |
| 宽泛权利放弃 | 高 | 放弃法定权利或基本权利 | 删除或限缩放弃范围 |
| 缺少数据保护条款 | 高 | 未约定个人信息处理（对应《个人信息保护法》等） | 补充符合适用法律的数据保护条款 |
| 自动续约陷阱 | 中 | 自动续约且退出机制繁琐 | 增加清晰的不续约通知机制 |
| 过高违约金 | 中 | 违约金明显超出可能的实际损失 | 核实违约金与预估损失是否相当 |
| 宽泛竞业限制 | 中 | 竞业范围、期限、地域过宽 | 限缩范围、期限（一般不超过 2 年）、地域 |
| 永久保密 | 中 | 保密义务无期限 | 设定合理期限（常见 3-5 年） |
| 不利管辖 | 中 | 争议解决地点/仲裁地对己方明显不利 | 争取中立或己方所在地管辖 |
| 范围变更无控制 | 中 | 没有变更管理流程 | 增加变更管理及对应计价机制 |
| 不利付款条款 | 中 | 账期过长或验收标准主观 | 争取更短账期、客观验收标准 |
| 缺少不可抗力条款 | 中 | 未约定不可抗力免责 | 补充标准不可抗力条款 |
| 缺少审计权 | 低 | 无权审计对方履约或财务情况 | 增加合理的审计权条款 |
命中风险的严重度不是自动结论——同一条款在不同交易背景下重要性不同（例如"无限 责任"在小额短期合同里未必是问题）。报告里说明为什么这条被标记，而不是机械套用 表格。
第三步：完整性检查
对照第一步选定的关键条款清单，检查合同是否遗漏了该类合同通常应有的条款。缺失本 身不一定是风险（可能双方另有安排），但要在报告里列出，交给用户判断。
同时检查基本要素：双方主体名称是否明确、签署日期、盖章/签字位置是否存在（如果 用户提供的是扫描件或图片，检查是否能看到签章）。
第四步：输出审查报告
固定结构：
# 合同审查报告
**合同类型：** [识别结果]
**审查范围：** [基于用户提供的文本/文件，说明是否为节选]
## 风险清单
### 🔴 高风险
- **[风险名称]**（第 X 条）：原文"[逐字引用]"。[为什么是问题]。建议：[修改建议]
### 🟡 中风险
[同上格式]
### 🟢 提示
[同上格式，或缺失条款提示]
## 缺失的关键条款
- [该类合同通常应有但本合同未见的条款]
## 需要澄清
- [信息不足、无法判断的地方]
## 总体说明
本报告基于通俗的条款风险识别，不构成正式法律意见。涉及金额较大、可能引发诉讼、
或跨境/涉外的合同，请在签署前交由持证律师复核。边界
- 不判断"这份合同能不能签"——只指出风险点和缺口，最终决策权在用户。
- 不臆测准据法下的具体法律后果（例如某条款是否可强制执行），除非用户明确说明 适用法律且你能引用具体依据；不确定时如实说"需要按适用法律进一步核实"。
- 两份合同对比、批量审查多份合同：这超出本技能范围，属于法律尽调场景，参考
