Also extracts injected system prompts from providers\n  that override Claude's identity. Fully self-contained — copy the code below\n  and run, no extra packages beyond httpx. Use when the user wants to verify a\n  Claude API key or endpoint, check if a third-party Claude service is authentic,\n  audit API providers for Claude authenticity, test multiple models in parallel,\n  or discover what system prompt a provider has injected.\n---\n\n# Claude Authenticity Skill\n\nVerify whether an API endpoint serves genuine Claude and optionally extract any\ninjected system prompt.\n\n**No installation required beyond `httpx`.** Copy the code blocks below directly\ninto a single `.py` file and run — no openjudge, no cookbooks, no other setup.\n\n```bash\npip install httpx\n```\n\n## The 9 checks (mirrors [claude-verify](https://github.com/molloryn/claude-verify))\n\n| # | Check | Weight | Signal |\n|---|-------|--------|--------|\n| 1 | Signature 长度 | 12 | `signature` field in response (official API exclusive) |\n| 2 | 身份回答 | 12 | Reply mentions `claude code` / `cli` / `command` |\n| 3 | Thinking 输出 | 14 | Extended-thinking block present |\n| 4 | Thinking 身份 | 8 | Thinking text references Claude Code / CLI |\n| 5 | 响应结构 | 14 | `id` + `cache_creation` fields present |\n| 6 | 系统提示词 | 10 | No prompt-injection signals (reverse check) |\n| 7 | 工具支持 | 12 | Reply mentions `bash` / `file` / `read` / `write` |\n| 8 | 多轮对话 | 10 | Identity keywords appear ≥ 2 times |\n| 9 | Output Config | 10 | `cache_creation` or `service_tier` present |\n\n**Score → verdict:** ≥ 85 → `genuine 正版 ✓` / 60–84 → `suspected 疑似 ?` / < 60 → `likely_fake 非正版 ✗`\n\n## Gather from user before running\n\n| Info | Required? | Notes |\n|------|-----------|-------|\n| API endpoint | Yes | Native: `https://xxx/v1/messages`  OpenAI-compat: `https://xxx/v1/chat/completions` |\n| API key | Yes | The key to test |\n| Model name(s) | Yes | One or more model IDs |\n| API type | No | `anthropic` (default, **always prefer**) or `openai` |\n| Extract prompt | No | Set `EXTRACT_PROMPT = True` to also attempt system prompt extraction |\n\n**CRITICAL — always use `api_type=\"anthropic\"`.**\nOpenAI-compatible format silently drops `signature`, `thinking`, and `cache_creation`,\ncausing genuine Claude endpoints to score < 40. Only use `openai` if the endpoint\nrejects native-format requests entirely.\n\n## Self-contained script\n\nSave as `claude_authenticity.py` and run:\n\n```bash\npython
