DeepSeek Harness 新增创建模式插件创建条目
在 Google 上的首选来源中添加 Unite.AI
DeepSeek于2026年10月3日发布了v.0.2.1-alpha.1预发版"DeepSeek Harness"，为插件管理增加了"让Agent创建插件"条目。 选择它将已有的草稿带入创建模式，执行则等待用户提交插件创建请求。
插件管理更改
创建者模式在此预释前已被记录。 v0.1.6-alpha.2 指出发布于2026年9月17日，描述了从Cordis动态定义和执行工具向通过插件管理器安装的持久插件的转变。 该版增加了一个插件页，用于安装和配置，同时进行现场启用和禁用，同时卸下运行时间插件。
十月预释保留了标准，创建器，以及自定义模式，当编码视图被禁用时。 内建的 PTC 和最小配置默认为标准，而现有的会话则保留其模式。 它的插件- bundle 修正在启用了新捆绑后缺失的依赖性，并在捆绑被禁用或未安装后 stale 依赖性映射。 替换已安装的软件包版本仍然需要重新启动。
创建模式工作流程
DeepSeek在全球公众预览中将Harness作为开源 agent的牵引。 其基于Cordis的架构使用可相容插件，用户可以通过Creator模式的聊天来安装扩展或构建，以扩展工具，技能和界面。
产品页面的创建者-模式演示使用Pomodoro计时器作为例子。 agent装入 Cordis 插件开发技能，检查提供者和运行时间槽，并写入软件包和客户端文件。 然后它引用插件管理器的捆绑安装工具，并检查活插件状态。 演示以被安装插件下列出的浮动计时器为结尾，带有Focus和shortbreak控件，并报告为已建，已安装，已核实。
可用性和插件限制
项目寄存器列出一个MIT许可证，以及来自npm或源代码的文档Web UI设置。 安装了Node.js后，npx@deepseek-ai/dsh网络启动界面；本地发布默认为http://127.0.0.1:3080并打开了默认浏览器。 源路由克隆了寄存器并使用pnpm安装，pnpm运行构建，和pnpm dsh web. Harness处于开发者预览中，预计会进行突破兼容性的修改，核心插件和API也在不断发展。
插件-市场文档描述了一个实验性的自定义插件市场，其中新增是一个Discover标签和一个只读的插件市场工具在Creator模式下被捆绑；使捆绑解除了两者。 没有索引源的DSH舰。 安装已发现的版本需要在正常兼容性和登记检查进行之前予以确认。 DSH的验证覆盖了索引文件格式，排除了由市场提供的标题，描述，图标，作者身份，以及源声称。
一份单独的安全通知将Harness描述为未经安全审计的实验开发者-审查软件。 Harness可以执行模型生成的代码和命令，加载第三方插件，并访问网络，进程，证书以及提供给它的文件。 不正确的输出，缺陷，配置错误，恶意输入，或不信任的插件会损坏主机，修改或删除文件，或披露数据和证书。 沙箱，批准提示，和许可控制可以减少风险，但即使正确执行，也不能保证隔离或防止损害。

DeepSeek Harness Adds Plugin-Creation Entry for Creator Mode
Add Unite.AI to your preferred sources on Google
DeepSeek published the v0.2.1-alpha.1 prerelease of DeepSeek Harness on October 3, 2026, adding a “Let Agent create a plugin” entry to plugin management. Selecting it carries the existing draft into Creator mode, and execution waits until the user submits the plugin-creation request.
Plugin Management Changes
Creator mode was already documented before this prerelease. The v0.1.6-alpha.2 notes, published September 17, 2026, describe a move away from Cordis dynamic definition and execution tools toward persistent plugins installed through Plugin Manager. That release added a Plugins page for installation and configuration with live enabling and disabling, alongside runtime plugin unloading.
The October prerelease keeps Standard, Creator, and custom modes available when coding view is disabled. Built-in PTC and Minimal configurations default to Standard, while existing sessions retain their mode. Its plugin-bundle fixes address missing dependencies after a new bundle is enabled and stale dependency mappings after bundles are disabled or uninstalled. Replacing an installed package version still requires a restart.
Creator Mode Workflow
Harness is presented by DeepSeek as an open-source agent harness in worldwide public preview. Its Cordis-based architecture uses composable plugins, and users can install extensions or build them through chat in Creator mode to extend tools, skills, and the interface.
The product page’s Creator-mode demonstration uses a Pomodoro timer as its example. The agent loads the Cordis plugin-development skill, inspects providers and runtime slots, and writes package and client files. It then invokes the plugin manager’s bundle-installation tool and checks the live plugin state. The demonstration ends with the floating timer listed under Installed plugins, with Focus and Short break controls, and reports it as built, installed, and verified.
Availability and Plugin Limits
The project repository lists an MIT license and documents Web UI setup from npm or source. With Node.js installed, npx @deepseek-ai/dsh web starts the interface; a local launch defaults to http://127.0.0.1:3080 and opens the default browser. The source route clones the repository and uses pnpm install, pnpm run build, and pnpm dsh web. Harness is in developer preview, compatibility-breaking changes are expected, and the core plugins and APIs are evolving.
The plugin-market documentation describes an experimental Custom plugin markets bundle that adds a Discover tab and a read-only plugin_market tool in Creator mode; disabling the bundle removes both. DSH ships without an index source. Installing a discovered version requires confirmation before the normal compatibility and registry checks proceed. DSH’s validation covers the index file format and excludes the titles, descriptions, icons, authorship, and source claims supplied by a market.
A separate safety notice describes Harness as experimental developer-preview software that has not undergone a security audit. Harness can execute model-generated code and commands, load third-party plugins, and access the network, processes, credentials, and files made available to it. Incorrect output, defects, misconfiguration, malicious input, or untrusted plugins can damage the host, modify or delete files, or disclose data and credentials. Sandboxing, approval prompts, and permission controls can reduce risk, but they do not guarantee isolation or prevent damage, even when correctly enforced.
