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

cease-desist 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 9d 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.

How it starts

The opening of the file, as written. The whole thing — 244 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/cease-desist

两种模式。选一:

  • /ip-legal:cease-desist --send — 起草警告函,校准至你的执法姿态。发送前运行响亮的关口。
  • /ip-legal:cease-desist --receive — 对收到的警告函做分诊。产出选项备忘录附建议。

指令

  1. 读取实践档案。 加载 ~/.claude/plugins/config/claude-for-legal/ip-legal/CLAUDE.md。如含占位符,停止并提示运行 /ip-legal:cold-start-interview
  2. 检查事项工作区。
  3. 根据参数分发: --send 运行发送模式。--receive 运行接收模式。无参数时询问一次。
  4. 尊重关口。 发送模式中,响亮关口在草稿落盘前运行。不要跳过。
  5. 尊重审批矩阵。## 执法姿态 → 审批矩阵 中提取警告函行的审批人。提取自动升级条件。在关口中呈现两者。
  6. 适当交接。 接收模式中,如果建议坚决回应,提供链入发送模式。如果建议以确认不侵权之诉或无效宣告先发制人,按实践档案升级至外部律师——不要起草。

示例

/ip-legal:cease-desist

目的

侵权警告函主张一项法律权利并要求某人停止做某事。它是IP执业中发送或接收的最重要的 函件之一。发送一封是迈向诉讼的第一步——收件人可在其选择的管辖地提起确认不侵权 之诉,且过度或恶意主张可被用于反制发送人。收到一封启动时限并强制决策。 本技能以该决定应得的护栏处理两侧。

对外发送文件(发送模式): 起草的警告函发送给对方当事人。对外函上包含 保密 — 律师工作成果的抬头。内部草稿、发送前摘要和分诊备忘录保留该抬头。

法域假设

知识产权权利具有地域性——中国注册商标的保护限于中国大陆境内。著作权基于国际公约 (伯尔尼公约)具有多边性,但执法和法定赔偿(著作权法第54条 [法条原文])取决于 当地法律。本技能假定事项或实践档案中声明的法域。如侵权行为、对方当事人或管辖地 在其他法域,标注——本稿可能不直接适用。

发送模式 — 起草侵权警告函

第1步:识别权利

我们在主张哪项知识产权?

  • 商标 — 是否注册?在哪里(CNIPA/其他国家)?注册号和类别?或仅为未注册驰名商标(首次使用日期、地理范围、知名度证据)?
  • 著作权 — 是否登记?作品名称、登记号、日期?或未登记(注:中国著作权登记为自愿登记,可作为初步证据,《最高人民法院关于审理著作权民事纠纷案件适用法律若干问题的解释》第7条)?
  • 专利 — 发明、实用新型还是外观设计?专利号、授权日?
  • 多种 — 分别识别。

第2步:识别侵权行为

用具体事实而非形容词描述侵权行为:

  • 在做——主体名称、个人、平台账号?
  • 什么——被控侵权商标、被控抄袭作品、被控侵权产品?附样品或描述。
  • 哪里——网站URL、电商平台链接、实体零售、社交媒体?
  • 从何时起——首次观察日期、你能记录的最早使用日期?
  • 证据——截图、购买记录、监测服务线索、消费者混淆报告?

第3步:识别关系

我们与收件人之间是什么关系?

  • 竞争对手(直接或间接)— 适用标准姿态
  • 经销商/渠道伙伴 — 语气调整;考虑软函路径
  • 前被许可人/前员工/前合伙人 — 合同条款可能适用;引用它们
  • 陌生人/随机侵权人 — 标准
  • 当前客户/合作伙伴 — 按实践档案自动升级;起草前标注

第4步:识别诉求

客户实际想要什么?

  • 停止 — 停止侵权使用
  • 提供信息 — 报告销量、利润、体量
  • 销毁 — 销毁或召回侵权产品
  • 赔偿 — 金钱赔偿
  • 转移/转让 — 转让域名、移交账户、转让被控标识或作品
  • 公开纠正 — 删除侵权内容、公开声明
  • 书面确认 — 在某日前作出合规承诺
