| description | 验证 Claude 模型是否为"纯血"官方模型，检测掺假、套壳、降级等问题的完整指南 |
| type | flexible |
本技能提供一套完整的验证方法，用于检测 Claude 模型是否为官方原版（"纯血"），识别可能的掺假、套壳、模型降级（如用 4.5 冒充 4.6）等问题。
| 序号 | 检测方法 | 检测目标 | 复杂度 |
|---|---|---|---|
| 1 | 分词器测试 | 验证是否为 Claude 原生分词器 | ⭐⭐ |
| 2 | count_tokens 接口 | 验证 API 完整性 | ⭐ |
| 3 | 知识库截止时间 | 判断具体模型版本 | ⭐ |
| 4 | 联网搜索测试 | 验证 CC 原生功能 | ⭐ |
| 5 | MCP 工具调用 | 验证工具链支持 | ⭐⭐⭐ |
| 6 | 提示词注入测试 | 验证系统提示词处理 | ⭐⭐ |
| 7 | 温度参数测试 | 验证参数真实性 | ⭐ |
| 8 | Signature 验证 | 验证工具调用签名 | ⭐⭐⭐ |
| 9 | 新参数验证 | 检测 Opus 4.6 特有参数 | ⭐⭐ |
Claude 的分词器没有开源，通过返回的 tokens 数量可以判断是否是 Claude 模型。

completion_tokens 应该是固定值（如 110）真正的 Claude API 支持 /v1/messages/count_tokens 接口，此接口对 Claude Code 的使用效果有很大影响。

不同版本的 Claude 模型有不同的知识库截止时间，通过询问可以判断实际使用的模型版本。

Claude Code 自带联网搜索功能，可以询问需要实时搜索才能回答的问题。
询问近期发生的事件，如"今天有什么科技新闻？"或"XXX 公司最新的财报数据"。
真正的 CC 支持 MCP (Model Context Protocol) 工具调用。
npm init playwright@latest
claude mcp add playwright npx @playwright/mcp@latest
让 Claude 执行自动化任务，如"打开浏览器访问 example.com 并截图"。

Claude Opus 4.6 引入了新的参数，可以通过测试这个参数来区分 4.5 和 4.6。
使用 Opus 4.6 特有的参数进行测试，如果参数有效则说明是 4.6。
在以下测试中，所有项目都必须通过才能确认为"纯血"Claude：
A: 分词器是 Claude 的核心组件，没有开源，最难伪造。
A: 此接口是 Claude API 的独有功能，对 CC 的使用体验影响很大。
A: 同时使用多种测试方法，包括流式和非流式测试。
A: 综合使用以上方法，准确率可达 95% 以上。
