为DeepSeek Harness创建并管理沙盒化的JavaScript工具，配备Monaco编辑器及以模型驱动的工具生命周期管理。

Project Overview项目介绍

Edited by Zhiwei Agent (zhiwei)由知微Agent(zhiwei)编辑

This is a native plugin built exclusively for DeepSeek Harness (DSH) that enables both users and the DSH agent to author, manage, and register custom JavaScript tools directly within DSH's settings interface. It ships with an embedded Monaco editor (the same editor that powers VS Code) that provides full TypeScript intellisense for tool code, so users get live completions and error diagnostics as they write. The plugin exposes three core functions to the DSH agent: create a new custom tool, remove an existing one, and list all currently registered custom tools.

All custom tool code runs in a restricted, fresh worker thread inside a sandboxed Node VM realm, with an explicit allowlist for allowed capabilities and hard resource budgets for time, memory, and output size. Tools cannot access inherited environment variables, spawn child processes, or access the filesystem outside their configured permission boundaries. This intentional design prevents unauthorized access to system resources and keeps DSH secure even when running user or model-authored custom code.

You can install the plugin directly from the GitHub release tarball using the DSH CLI plugin command, and no build step is required because all bundled assets are committed to the repository. After installation, you just need to restart the DSH web server to load the plugin properly. All configurable settings like timeout, memory limit, maximum number of stored tools, and network access allowance can be adjusted via the cordis.yml config file.

这是一个专为DeepSeek Harness（DSH）开发的原生插件，支持用户和DSH模型直接通过插件内置的设置界面创建、编辑和管理自定义JavaScript工具。插件自带基于Monaco（VS Code引擎）的编辑器，提供TypeScript智能提示，支持工具热注册，创建的工具可以跨会话持久保存。插件还向模型开放了三个核心能力：创建工具、删除工具和列出已有的自定义工具。

它解决了原本DSH无法灵活扩展能力的问题，现在用户不需要重新打包安装DSH就能随时添加自定义能力，模型也可以在会话中途自行创建持久化工具。所有自定义工具代码都在受限的独立Worker线程中执行，拥有明确的权限边界和资源预算，避免了未授权访问和资源滥用问题。

工具支持全局和工作区两种执行范围，以及全局存储和工作区存储两种位置，可灵活满足不同场景需求。安装可通过DSH的插件命令直接从GitHub包安装，不需要额外编译步骤。所有配置项都可以在cordis.yml中调整，包括超时时间、内存限制、最大工具数量等。

请帮我安装这个 DSH 插件。安装前先完成【兼容性检查 + 安全性检查】，检查通过再动手。

插件：dsh-custom-tool（omdsh-dev/dsh-custom-tool）
仓库：https://github.com/omdsh-dev/dsh-custom-tool
本站详情页：https://www.yhbd.top/plugins/omdsh-dev-dsh-custom-tool/
本站登记：类型 plugin · 归类 原生 DSH 插件 · 许可证 MIT · ⭐ 23 · 最近提交 2026-08-16 · 主语言 TypeScript

按下面顺序执行，每步先把结论告诉我，再进入下一步：

【1 兼容性检查】
① 我这边：DSH 版本、Node 版本、操作系统、当前 profile（web / desktop）。
② 读它的 README、package.json、插件 manifest，列出它要求的 DSH 版本 / Node 版本 / 操作系统 / 外部依赖 / 需要另外先装的运行时。
③ 逐条比对，结论只写「满足 / 不满足 / 未知」三种；不满足的给出可行替代方案。
④ 检查是否和我已装的插件冲突：命令名重复、skill / tool 重名、端口占用、重复注册的 MCP server。

【2 安全性检查】
① 仓库可信度：和上面「本站登记」是否一致；star / fork 数、创建时间、最近提交，是否归档或长期停更。
② 安装脚本：逐行看 package.json 的 preinstall / install / postinstall，以及 install.sh、setup.ps1 之类脚本。出现 curl|bash、下载后直接执行、混淆代码、访问与插件功能无关的域名，立刻停下来告诉我，不要继续装。
③ 依赖：列出新增依赖，标出无人维护、或与知名包拼写近似的可疑包（typosquatting）。
④ 权限与副作用：它会读写哪些目录、访问哪些域名、需要哪些 DSH 权限（filesystem / network / shell / clipboard 等），以及怎么卸载和回滚。
⑤ 如果它要求 sudo / 管理员权限，或权限明显超出功能所需，先停下来问我。

【3 安装】
上面两步没有「不满足」和「高危项」时才执行；用官方推荐方式安装，不要自行提权。

【4 汇报】
用表格输出：检查项 / 结论 / 依据 / 是否需要我决策。拿不准的一律写「未知」并说明要我怎么确认——不要猜，也不要替我决定。

Send this message to DSH in your current session: it verifies compatibility and security first (answering met / not met / unknown item by item) and only installs once everything checks out — it will stop and ask you if it finds a high-risk item. The box scrolls; the copy is the full prompt. CLI install commands may not be accurate across systems, so DSH is the safer route.把上面这条消息直接发给当前会话里的 DSH：它会先核对兼容性与安全性（逐条给「满足 / 不满足 / 未知」），确认没问题再安装，有高危项会停下来问你。框内可滚动，复制到的是完整提示词；安装命令不一定准确，发给 DSH 更稳。

dsh-custom-tool

Custom tools for the DeepSeek Harness: users author their own JavaScript tools in the settings UI with a Monaco (VS Code) editor and TypeScript intellisense, and the model grows and prunes the same toolset itself through custom_tool_create / custom_tool_remove / custom_tools_list. Every tool is durable, hot-registered, and written into the model prompt on the next step.

The Custom Tool settings page

The tool editor

Problems it solves

  • Users cannot extend their agent: before this plugin, adding a capability meant shipping a harness package. Now a tool is a form in the settings UI — name, description, parameters, code — saved live and callable by the model immediately.
  • The model cannot grow itself: custom_tool_create lets the model persist tools mid-session (hot-registered, visible on its next step), with the same validation gate the UI uses — the model cannot persist anything the settings UI would refuse.
  • User-authored code runs in a restricted worker: every call executes in a fresh worker thread inside a node:vm realm with an explicit allowlist, Node Permission Model, and hard budgets. The worker receives no inherited environment variables, filesystem access outside its configured scope, or child-process capability.

Features

  • Settings UI (Custom Tool section, own nav glyph): list, create, edit, enable/disable, delete. Model-created and workspace-scoped tools are badged. Every string follows the harness locale (Chinese / English) and switches with the language preference.
  • Monaco editor: VS Code engine + TypeScript language service; args typed from the parameter schema, env/sandbox globals declared, completions and diagnostics live. Editor and TS workers are bundled inline — the client bundle is a single file.
  • Durable store: tools live in the custom-tools settings namespace (schema defaults, composition base, user document — the ordinary settings layering). Edits apply live; restart restores them.
  • Live registration: enabled tools register into ctx.tools the moment the settings write commits; disabled/removed tools unregister immediately. The harness assembles tool schemas into the system prompt automatically.
  • Model self-service: custom_tool_create (upsert by name), custom_tools_list, and custom_tool_remove share the UI's validation gate and the ownership rules below.
