Claude Agent SDK v0.3.281：Settings
v0.3.281
推荐理由
TypeScript开发者必读：Settings.attribution字段类型发生破坏性变更，不调整类型检查代码会导致编译失败。建议立即升级并审查相关类型定义。
What's changed
变更内容
- Added optional trigger, user_message_uuid and timestamp fields to the conversation_reset message so clients can tell what reset the conversation, match a /clear to its message, and show when the reset happened
- Fixed permission and dialog callbacks still being invoked for requests that arrived after close()
- Fixed control requests issued after a query closed hanging or leaking, and permission prompts that could not be cancelled after a cancelled request was redelivered
- Fixed session_state_changed staying at requires_action after an overlapping permission prompt and sandbox network-access prompt were both answered
- Improved SDK package size and load time: sdk.mjs no longer bundles unused dependencies (1.47 MB → 0.97 MB)
- Improved startup time for query() sessions with in-process MCP servers (createSdkMcpServer) by running their handshake inside the SDK; initialize may now wait up to 250 ms for them
- Improved SDK session start-up: the CLI now answers the host's initialize request before starting its background start-up work
- Changed the Settings type's attribution field to boolean | {...}; TypeScript code that reads attribution.commit from returned settings needs a type narrow
- Updated to parity with Claude Code v2.1.281
- 在 conversation_reset 消息中添加了可选的 trigger、user_message_uuid 和 timestamp 字段，以便客户端能够识别是什么触发了对话重置、将 /clear 命令与其对应的消息匹配，并显示重置发生的时间
- 修复了在 close() 之后到达的请求仍会触发权限和对话框回调的问题
- 修复了在查询关闭后发出的控制请求出现挂起或资源泄漏的问题，以及在被取消的请求重新投递后无法取消权限提示的问题
- 修复了在重叠的权限提示和沙箱网络访问提示均被响应后，session_state_changed 仍停留在 requires_action 状态的问题
- 优化了 SDK 包大小和加载时间：sdk.mjs 不再捆绑未使用的依赖项（从 1.47 MB 减少至 0.97 MB）
- 通过让 SDK 内部运行握手过程，改善了使用进程内 MCP 服务器（createSdkMcpServer）的 query() 会话的启动时间；initialize 现在最多可等待 250 ms 以完成握手
- 优化了 SDK 会话启动流程：CLI 现在会在开始后台启动工作之前先响应主机的 initialize 请求
- 将 Settings 类型的 attribution 字段更改为 boolean | {...}；读取返回设置中 attribution.commit 的 TypeScript 代码需要进行类型收窄处理
- 更新以与 Claude Code v2.1.281 保持功能一致
