响应字段与官方 Messages API 规范一致

{
  "status": 200,
  "id": "msg_SJRMof0QspK8YnYv2cRGtdhM",
  "model": "claude-sonnet-4-5-20250929",
  "stop_reason": "end_turn",
  "usage": {
    "cache_creation_input_tokens": 0,
    "cache_read_input_tokens": 63,
    "input_tokens": 9,
    "output_tokens": 1
  },
  "topKeys": [
    "content",
    "id",
    "model",
    "role",
    "stop_reason",
    "stop_sequence",
    "type",
    "usage"
  ],
  "latencyMs": 1995,
  "text": "OK"
}

ID 前缀非官方常见的 msg_01，可能是自建代理生成

{
  "ids": [
    "msg_SJRMof0QspK8YnYv2cRGtdhM",
    "msg_ChuzmtchlyBoEdF7cnKHehMI"
  ]
}

篡改后的签名也被接受，且签名形态不像 Anthropic 签发：signature 是中转站伪造的，上游为逆向渠道（Kiro / Copilot / Cursor 等）或非官方代理

{
  "blockTypes": [
    "thinking",
    "tool_use"
  ],
  "stop_reason": "tool_use",
  "signatureLength": 328,
  "signaturePrefix": "Ul5u0mk9tXPE",
  "thinkingPreview": "The user wants me to check the weather in Tokyo using the get_weather tool. This…",
  "thinkingMode": "enabled",
  "signatureLooksOfficial": false,
  "roundTrip": {
    "validStatus": 200,
    "tamperedStatus": 200,
    "tamperedError": "{\"content\":[{\"text\":\"The current weather in Tokyo is 22°C and sunny.\",\"type\":\"text\"}],\"id\":\"msg_JJcN9MctZADs0CzJBQFsd48A\",\"model\":\"claude-sonnet-4-5-20250929\",\"…"
  }
}

SSE 事件序列完整，符合官方规范

{
  "status": 200,
  "ttftMs": 2609,
  "eventCount": 8,
  "sequence": [
    "message_start",
    "ping",
    "content_block_start",
    "content_block_delta",
    "content_block_delta",
    "content_block_stop",
    "message_delta",
    "message_stop"
  ],
  "startId": "msg_lM867qJobGT8vcEzvFRnXLAo",
  "startUsage": {
    "cache_creation_input_tokens": 221,
    "cache_read_input_tokens": 41,
    "input_tokens": 14,
    "output_tokens": 0
  },
  "deltaUsage": {
    "output_tokens": 9,
    "input_tokens": 14,
    "cache_read_input_tokens": 41,
    "cache_creation_input_tokens": 221,
    "cache_creation": {
      "ephemeral_5m_input_tokens": 221
    }
  }
}

Tool Use 正常，参数与 stop_reason 均符合规范

{
  "stop_reason": "tool_use",
  "blockTypes": [
    "tool_use"
  ],
  "toolId": "toolu_DH7jUS4FRnLoN5KJRjS6RO",
  "input": {
    "city": "Tokyo"
  }
}

续写包含答案但格式不精确

{
  "continuation": "```json\n{\"capital\": \"Paris\"}\n```"
}

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 (9 tokens)，无注入痕迹

{
  "input_tokens": [
    9,
    9
  ],
  "output_tokens": [
    1,
    1
  ],
  "expectedInputApprox": "10-16"
}

模型拒绝谈论自己的指令：存在禁止透露的隐藏 system prompt，逆向渠道典型特征

{
  "reply": "I can't discuss that."
}

模型自称由「Windsurf」训练，而非 Anthropic

{
  "who": "Windsurf",
  "math": [
    "391",
    "391"
  ],
  "models": [
    "claude-sonnet-4-5-20250929",
    "claude-sonnet-4-5-20250929",
    "claude-sonnet-4-5-20250929"
  ]
}

模型无法读出 PDF 内容：文档能力被剥离

{
  "status": 200,
  "secret": "KIWI-1631",
  "reply": "I don't see any PDF attached to your message. Could you share the PDF file you'd…"
}

缓存写入 3144 tokens 但第二次只命中 20 tokens：命中量与写入量不匹配，缓存计量疑似伪造或上游改写了前缀

{
  "first": {
    "input": 9,
    "creation": 3144,
    "read": 20
  },
  "second": {
    "input": 9,
    "creation": 3144,
    "read": 20
  }
}

32k 上下文即失败：召回错误（回复：I can't discuss that.）

{
  "tiers": [
    {
      "tokens": 32000,
      "ok": false,
      "status": 200,
      "latencyMs": 4251,
      "inputTokens": 19970,
      "reply": "I can't discuss that.",
      "stop": "end_turn"
    }
  ]
}
