消息 ID 符合官方格式且每次唯一

{

    "msg_011CeWyYNA8DihZkY3et6oPa"
  ]
}

首轮签名形态为 Anthropic 官方，但篡改后的签名回传也被接受：中转站在转发时改写了对话历史（剥离/替换 thinking 块），签名验证链在中转站被切断——多账号号池轮换的典型做法。上游可能是官方账号，但你无法验证后续请求是否仍由官方处理

{
  "blockTypes": [
    "thinking",

SSE 事件序列完整，符合官方规范

    "message_start",
    "content_block_start",

Tool Use 正常，参数与 stop_reason 均符合规范

{
  "stop_reason": "tool_use",
  "blockTypes": [
    "tool_use"
  ],
  "toolId": "toolu_01Q7fApEmroFRFGzkbBwZAvg",
  "input": {
    "city": "Tokyo"
  }
}

该模型不支持 assistant 预填充（Claude 5 代已移除此特性），跳过

stop_sequence 命中并正确回填

{
  "stop_reason": "stop_sequence",
  "stop_sequence": "FIVE",
  "text": "ONE TWO THREE FOUR "
}

用量稳定 (5 tokens)，无注入痕迹

{
  "input_tokens": [
    5,
    5
  ],
  "output_tokens": [
    1,
    1
  ],
  "expectedInputApprox": "10-16"
}

模型复述出了隐藏 system prompt，中转站在注入指令

{
  "reply": "I'm Claude Code, Anthropic's official CLI for Claude. I won't reproduce my setup text, but I'm glad to help with what you're working on."
}

身份为 Anthropic，temperature=0 输出稳定

{
  "who": "Anthropic",
  "math": [
    "391",
    "391"
  ],
  "models": [
    "claude-sonnet-4-6",
    "claude-sonnet-4-6",
    "claude-sonnet-4-6"
  ]
}

PDF 内容识别正确

{
  "status": 200,
  "secret": "KIWI-1152",
  "reply": "KIWI-1152"
}

缓存写入 3228 tokens、第二次命中 3228 tokens，Prompt Caching 完整可用

{

    "input": 9,
    "creation": 3228,
    "read": 0
  },
  "second": {
    "input": 9,
    "creation": 0,
    "read": 3228
  }
}
