      feat(gateway): align body shape with real Claude Code CLI defaults · a25faeca
      keh4l authored
      Three field-level alignments in normalizeClaudeOAuthRequestBody to
      match real Claude Code CLI traffic byte-for-byte:
      
        1. temperature: previously deleted unconditionally; now passes
           through client value, defaults to 1 when absent (real CLI
           always sends temperature, default 1).
      
        2. max_tokens: defaults to 128000 when absent (real CLI default).
      
        3. context_management: when thinking.type is enabled/adaptive
           and the client did not provide context_management, inject
           {"edits":[{"type":"clear_thinking_20251015","keep":"all"}]}
           to mirror real CLI behavior.
      
      tool_choice removal is unchanged (Claude Code OAuth credentials
      do not allow client-supplied tool_choice).
      
      Tests updated:
        - gateway_body_order_test.go: temperature/max_tokens are now
          expected in output; tool_choice still removed.
        - gateway_prompt_test.go: system array is now 2 blocks
          (billing + cc prompt), assertions adjusted.
        - gateway_anthropic_apikey_passthrough_test.go: same 2-block
          assertion.

      fix: 修复非CC客户端OAuth伪装被Anthropic检测为第三方应用的问题 · 1c9a2128
      shaw authored
      commit f3aa54b7 的 rewriteSystemForNonClaudeCode 未能通过 Anthropic 第三方检测,
      根因是两个关键信号与真实 Claude Code 不一致:
      
      1. anthropic-beta 头缺少 claude-code-20250219:伪装路径主动将该 beta
         加入 drop set 并移除,但 Anthropic 依赖此 beta 识别 Claude Code 请求。
         修复:非 haiku 模型的伪装请求强制包含 claude-code beta。
      
      2. system 字段使用 string 格式而非 array+cache_control:真实 Claude Code
         始终以 [{type,text,cache_control:{type:"ephemeral"}}] 发送 system,
         string 格式成为第三方检测信号。
         修复:rewriteSystemForNonClaudeCode 改为注入 array 格式。
      
      附带调整:stripSystemCacheControl 按 system 是否被重写动态决定,
      重写时保留 CC prompt 的 cache_control,未重写时(haiku/已含CC前缀)
      保持原有剥离行为。

      fix: 非Claude Code客户端system prompt迁移至messages以绕过第三方应用检测 · f3aa54b7
      shaw authored
      Anthropic近期引入基于system参数内容的第三方应用检测机制,原有的前置追加
      Claude Code提示词策略无法通过检测(后续内容仍为非Claude Code格式触发429)。
      
      新策略:对非Claude Code客户端的OAuth/SetupToken账号请求,将system字段
      完整替换为Claude Code标识提示词,原始system内容作为user/assistant消息对
      注入messages开头,模型仍接收完整指令。
      
      仅影响/v1/messages路径,chat_completions和responses路径保持原有逻辑不变。
      真正的Claude Code客户端请求完全不受影响(原样透传)。
