claude-authenticity
帮助识别 Claude 伪装或注入系统提示，适合服务验证与安全检测。
会向目标端点发起探测请求，可能触发服务限制或引发合规问题。
对指定 API 端点进行规则化检测以判断其是否为真正的 Claude 服务的技能。
用九条规则检测某个 API 端点是不是托管真正的 Claude，并能提取服务商是否注入的 system prompt。适合你要验证 Claude 的 API key/endpoint、审计第三方 Claude 服务或并行测试多个模型时使用。只需 Python + httpx 即可运行，给出带权重的判定和可复现的证据，方便排查与复测。

Detect whether an API endpoint is backed by genuine Claude (not a wrapper, proxy, or impersonator) using 9 weighted rule-based checks that mirror the claude-verify project. Also extracts injected system prompts from providers that override Claude's identity. Fully self-contained — copy the code below and run, no extra packages beyond httpx. Use when the user wants to verify a Claude API key or endpoint, check if a third-party Claude service is authentic, audit API providers for Claude authenticity, test multiple models in parallel, or discover what system prompt a provider has injected.
