Claude Agent SDK TypeScript v0.3.287：MCP工具截断与WebFet
v0.3.287
推荐理由
MCP 大响应截断与 WebFetch 分离机制属破坏性变更，直接改变现有解析逻辑。请检查对 tool_use_result 的处理代码，确保兼容新字段与超时行为。
What's changed
变更内容
- Added optional remote-session latency fields (first_text_post_queue_wait_ms, first_text_post_queued_behind) to the success result message
- Fixed includePartialMessages streams sending a cut-short reply's message_stop late or never, so apps could show the reply as still in progress
- Fixed the error for a revoked claude.ai login, which now reads "Failed to authenticate: OAuth token revoked" instead of a generic or "does not have access" message
- Fixed a tool call to an in-process MCP server being left waiting after toggleMcpServer() disabled the server or setMcpServers() removed it
- Fixed commands_changed arriving before init, or twice, at session start: the initialize response now includes commands registered at startup
- Changed tool_use_result for a WebFetch or WebSearch call that steps aside for a priority "now" message to { detachedToolCall: true }; the result follows in a later turn
- Changed tool_use_result for MCP tools: structuredContent over 1,048,576 JSON characters is left off and structuredContentOmitted: true set, except for SDK-server and MCP Apps tools
- Updated to parity with Claude Code v2.1.287
- 在成功结果消息中添加了可选的远程会话延迟字段（first_text_post_queue_wait_ms、first_text_post_queued_behind）
- 修复了 includePartialMessages 流发送截断回复时 message_stop 延迟或从未发送的问题，这可能导致应用显示回复仍处于进行中状态
- 修复了 claude.ai 登录被撤销时的错误提示，现在显示为“Failed to authenticate: OAuth token revoked”，而非通用的错误或“does not have access”消息
- 修复了在 toggleMcpServer() 禁用服务器或 setMcpServers() 移除服务器后，针对进程内 MCP 服务器的工具调用仍保持等待状态的问题
- 修复了 commands_changed 在会话开始时出现在 init 之前或重复出现两次的问题：initialize 响应现在包含启动时注册的命令
- 当 WebFetch 或 WebSearch 调用因优先级为“now”的消息而让路时，tool_use_result 更改为 { detachedToolCall: true }；结果将在后续轮次中返回
- 更改了 MCP 工具的 tool_use_result：对于超过 1,048,576 个 JSON 字符的 structuredContent 将被省略，并设置 structuredContentOmitted: true，SDK-server 和 MCP Apps 工具除外
- 更新以与 Claude Code v2.1.287 保持一致
