DeepSeek Harness dsh-v0.1.3-alpha.1 release notes

Web 支持上传任意类型的通用文件：文件与图片可在同一预览区混排，后台上传支持进度、取消与会话切换续显，模型可通过已保存路径使用现有文件工具按需读取。 @CreatixChu
所有出站网络请求都会遵循启动环境中的 HTTP_PROXY、HTTPS_PROXY、ALL_PROXY 与 NO_PROXY 配置。 @LegGasai
Python SDK 新增 macOS x64 runtime wheel，可在 Intel 架构的 Mac 上安装并运行随包 runtime。 @koalazf99
read_image 的顶层与 PTC 嵌套工具调用会在 Web 工具卡中直接渲染图片，不再展示原始附件对象。 @Chinesezjc
模型探测新增对自定义模型提供商 models 对象和 Anthropic 原生模型列表的支持，并支持回填模型名称、上下文窗口及最大输出 token 的回填。 @LegGasai

Skill 选择器支持模糊搜索；优化聊天气泡中的的 Skill 和命令引用。 @LegGasai
统一会话内可点击链接的颜色、hover/focus 样式和分类图标，优化 Markdown 链接、文件引用、网页来源、产物链接与 Workflow 成员链接的辨识度。 @yixiangihsiang
统一未观察文件写入与编辑失败的 FS_NOT_OBSERVED 诊断，保留文件路径、结构化错误码和原始原因。 @turtle1999
Windows 上的本地非终端子进程不再弹出控制台窗口。 @turtle1999
Agent Team 的 send_message 统一采用 steer 语义，并在跨 Agent 和冷恢复投递中保留发送者归属与顺序。 @Dudu-0223

**破坏性变更：**Session persistence API 改为由生命周期持有的 SessionHandle；agentLoop.create() 改为异步，新增session锁，同一session至多被一个进程持有。 @turtle1999
Session format 升级至 v2：旧 v0/v1 日志通过不可变的相邻 generation 迁移到当前格式，Assistant 流按 attempt 聚合进持久化 settlement，同时 Web 保持实时增量显示。 @tianyicui
已知的性能缺陷：本版本存在一项已知的性能回退，可能影响部分历史session加载的响应速度；我们将在下一个版本中修复。

Web now supports uploads of arbitrary file types: files and images share a preview area, background uploads expose progress and cancellation and remain visible across conversation switches, and models can use existing file tools to read saved paths on demand. by @CreatixChu
All outbound network requests honor the HTTP_PROXY, HTTPS_PROXY, ALL_PROXY, and NO_PROXY settings from the startup environment. by @LegGasai
The Python SDK adds a macOS x64 runtime wheel, allowing Intel-based Macs to install and run the bundled runtime. by @koalazf99
Render images directly in Web tool cards for top-level and PTC-nested read_image calls instead of showing raw attachment objects. by @Chinesezjc
Model discovery now supports models objects from custom model providers and native Anthropic model lists, and fills in model names, context windows, and maximum output tokens when needed. by @LegGasai

Immediately abort the active model turn when a goal is paused manually in Web, preventing the running model from continuing or resuming within the same turn. by @mektpoy
Preserve tool-call IDs and names across DeepSeek streaming continuation chunks, preventing empty tool names and conversation records that cannot be reopened. by @LegGasai
Prevent the Python SDK single-file runtime from rewriting Bash commands that begin with node as dsh runtime invocations. by @imccyu
Open a conversation selected from search in its Workspace, expand it, and scroll it into view instead of leaving the search interface open. by @Dudu-0223
Fix path separators, titles, and absolute-path validation for Windows drive-root Workspaces so drive roots work correctly. by @turtle1999
Fix Session cache reads. by @imccyu

The Skill picker supports fuzzy search, with improved Skill and command references in chat bubbles. by @LegGasai
Unify colors, hover and focus states, and category icons for clickable conversation links, making Markdown links, file references, web sources, artifact links, and Workflow member links easier to distinguish. by @yixiangihsiang
Standardize FS_NOT_OBSERVED diagnostics for unobserved file writes and failed edits while preserving the file path, structured error code, and original cause. by @turtle1999
Prevent local non-terminal subprocesses from opening console windows on Windows. by @turtle1999
Agent Team send_message consistently uses steer semantics and preserves sender attribution and ordering across agents and cold recovery. by @Dudu-0223

Breaking change: The Session persistence API is now owned by lifecycle-scoped SessionHandles; agentLoop.create() is asynchronous, and a new Session lock ensures that each Session is held by at most one process. by @turtle1999
Upgrade the Session format to v2: immutable adjacent-generation migrations convert v0/v1 logs to the current format, Assistant streams are aggregated by attempt into durable settlements, and Web preserves real-time incremental rendering. by @tianyicui
This release has a known performance regression that may affect responsiveness in some scenarios. We will address it in the next release.
