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

clearance 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.

/clearance

这是一份初步检索,非商标清除法律意见。 商标清除法律意见需要完整的专业检索和 执业商标律师的判断。"未发现明显冲突"的结果意味着本次初检未发现任何东西——不意味 商标无冲突。有客户因通过排除检索的商标而被起诉。

指令

  1. 读取 ~/.claude/plugins/config/claude-for-legal/ip-legal/CLAUDE.md。如包含 [占位符],停止并引导至 /ip-legal:cold-start-interview
  2. 遵循以下工作流。
  3. 运行录入(商标、商品/服务、类别、法域、视觉/风格化)。
  4. 排除性筛查固有障碍——通用名称、描述性、欺骗性、地理名称、姓氏、虚假关联、 禁止事项、功能性。
  5. 针对已连接的检索工具进行近似商标查询(国家知识产权局商标数据库、或任何可用的MCP)。 如果无连接,在输出中说明,并仅进行因素分析。
  6. 逐项分析混淆可能性因素——根据中国商标法第57条混淆标准。每项均标注;绝不下结论。
  7. 将初检备忘录写入事项文件夹(如有活动事项)或实践输出文件夹。按角色冠以工作成果抬头。
  8. 以建议的后续步骤和非律师关口结束(如角色为非律师)。

本技能绝不作出商标无冲突的结论。若不确定,标注——由律师决定。

示例

/ip-legal:clearance "APEXLEAF 户外服装产品线,计划在中美欧上市"
/ip-legal:clearance

(技能将询问商标、商品、类别和法域。)


这是一份初步检索,非商标清除法律意见

在每个输出的顶部说这句话。不要遗漏。不要弱化。

这是一份初步检索,非商标清除法律意见。 商标清除法律意见需要完整的专业检索 (国家知识产权局商标数据库、地方工商登记、域名和社会化媒体检索、外观设计检索等) 以及律师对混淆可能性的判断,后者依赖于结构化初检无法完全评估的因素。本技能的 "未发现明显冲突"结果意味着本次初检未发现任何东西——不意味商标无冲突。有客户 因通过排除检索的商标而被起诉。执业商标律师在任何人采用、申请或投资该商标前进行评估。

这是插件中最响的护栏。低估冲突是单行道——卡车上的标识、已上市的产品、已提交的 商标申请,底下都埋着问题。高估是双行道——律师在审阅中缩小清单。留在双行道一侧。


事项上下文

事项上下文。 检查实践级 CLAUDE.md 中的 ## 事项工作区。如果 已启用(法务用户的默认值),跳过本段——技能使用实践级上下文,事项机制不可见。如果已启用且无活动事项,询问:"这是哪个事项?运行 /ip-legal:matter-workspace switch <代号> 或说 实践级。"加载活动事项的 matter.md 获取事项特定上下文和覆盖项。将输出写入事项文件夹 ~/.claude/plugins/config/claude-for-legal/ip-legal/matters/<代号>/。除非 跨事项上下文开启,否则绝不读取其他事项的文件。


先加载实践档案

清除检索前,读取 ~/.claude/plugins/config/claude-for-legal/ip-legal/CLAUDE.md。提取:

  • 角色来自 ## 谁在使用(律师 vs. 非律师改变工作成果抬头和下方的非律师关口)。
  • 注册地执法地来自 ## IP实践档案## 执法姿态(用户未指定时的默认法域)。
  • 集成来自 ## 可用集成——决定哪些检索可用、降级方案是什么及输出中的来源标注。
  • 决策立场来自 ## 对主观法律判断的决策立场——本技能绝不作出"不构成近似/不构成混淆"的结论。

如果配置文件含 [占位符][你的公司名称],弹出此提示:

我注意到你尚未配置实践档案——我据此定制立场、法域和审批链。

两个选择:

  • 运行 /ip-legal:cold-start-interview(2分钟)配置档案,然后我将针对你的实践进行定制。
  • "临时模式" 我将按通用默认值——中国法域、中等风险偏好、律师角色、无操作手册——并标注每个输出为 [临时模式 — 请配置实践档案以获取定制输出]

临时模式

如果用户说"临时模式",使用通用默认值正常检索:中等风险偏好、律师角色、中国法域(CNIPA + 商标法)、无操作手册。在审核备注和每项发现上标注 [临时模式]。在输出末尾附加提示。
