一个DeepSeek Harness插件,用于在聊天会话中通过图片预览Mermaid图表
Project Overview项目介绍
This is a native plugin built exclusively for DeepSeek Harness (DSH) Web interface that enables image previews of Mermaid diagrams in chat conversations. Any mermaid code block marked with ``mermaid or ``mmd will be automatically rendered as an image by the plugin. It defaults to local rendering, with an optional fallback to an external rendering server if local rendering fails. It natively supports 14 common Mermaid diagram types and automatically adapts to DSH's light or dark UI theme.
The plugin mounts as an additive chain slot at conversation.chat.turnTail, so it never shadows existing DSH UI. Rendered diagrams appear as thumbnails at the end of the chat turn, and you can click to enlarge the image in place, click again to shrink it back without opening any popups. All runtime settings can be adjusted directly from the DSH plugin settings card, no restart required after changes. Values are saved to browser localStorage and applied immediately across all DSH sessions.
You can install the plugin via the DSH CLI directly from GitHub, or clone the source code and install it locally from your machine. After installation, you will need to restart your DSH Web profile for the plugin to take effect. To configure a custom fallback render URL or change other core settings, you need to edit your profile's cordis.patch.yml file, then restart DSH Web again. This plugin is released under the permissive MIT open source license, free for any use.
这是一个专为 DeepSeek Harness(DSH)Web 端开发的原生插件,用于将对话消息中的 Mermaid 代码块渲染为可预览的图片。插件默认使用本地渲染,本地渲染失败后可配置 fallback 到公共或自建的外部渲染服务器。它会自动适配 DSH 界面的浅色/深色主题,开箱即用支持 14 种常见 Mermaid 图表类型。
当 DSH 对话中出现用 ``mermaid 或 ``mmd 标记的 Mermaid 代码块时,插件会自动将其渲染为缩略图展示在对话末尾。用户点击缩略图可以放大查看,再次点击即可缩小,无需弹出新窗口。所有设置都可以在插件设置面板中实时调整,无需重启 DSH,适合经常需要生成查看 Mermaid 图表的 DSH 用户。
你可以通过 DSH CLI 从 GitHub 安装该插件的最新版、指定版本或开发版,也可以克隆源码后本地安装,安装完成后需要重启 DSH Web。如果你需要自定义 fallback 渲染地址,可以修改 profile 的 cordis.patch.yml 配置,修改后需要重启 DSH。该插件采用 MIT 许可证开源,完全免费使用。
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。

仓库:https://github.com/baconbao/dsh-mermaid-image-preview
本站详情页:https://www.yhbd.top/plugins/baconbao-dsh-mermaid-image-preview/
本站登记:类型 plugin · 归类 原生 DSH 插件 · 许可证 MIT · ⭐ 3 · 最近提交 2026-10-03 · 主语言 JavaScript
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 walks through these 9 checksDSH 会逐条核对这 9 项
Compatibility兼容性
- DSH, Node, OS and profile requirementsDSH 版本 / Node 版本 / 操作系统 / profile 是否满足要求
- External dependencies and runtimes (Electron / Python / Docker, ...)外部依赖与运行时(Electron / Python / Docker 等)是否齐备
- Conflicts with installed plugins: command names, skill / tool names, ports, duplicate MCP registration与已装插件是否冲突:命令名、skill / tool 重名、端口占用、重复 MCP 注册
Security安全性
- Repo matches the facts registered here; archived or abandoned?仓库是否与页面登记一致,是否归档或长期停更
- Safety of preinstall / install / postinstall and install.sh / setup.ps1preinstall / install / postinstall 与 install.sh、setup.ps1 是否安全
- curl|bash, download-then-execute, obfuscation, unrelated domains → stop immediatelycurl|bash、下载即执行、混淆代码、无关域名 → 立刻停止
- Typosquatting or unmaintained packages among the new dependencies新增依赖里有没有 typosquatting 或无人维护的包
- Requested permissions vs. what the feature actually needs申请了哪些权限、是否超出功能所需(filesystem / network / shell / clipboard)
- Any sudo / admin requirement, plus uninstall and rollback是否要求 sudo / 管理员权限,以及卸载与回滚方式
Anything uncertain must be marked unknown with a note on how to confirm it. This site's signal screen is a static snapshot, not a security audit.拿不准的必须标「未知」并说明要我怎么确认。本站的信号筛查是静态快照,不能替代安全审计。
Or use CLI install (for developers)或使用命令行安装(适合开发者)

dsh-mermaid-image-preview
A DeepSeek Harness Plugin for Previewing Mermaid Diagram Images
Preview Mermaid syntax as images via local rendering in DSH when a chat message contains a Mermaid fenced code block (```mermaid or ```mmd).

Features and how it works
- Preview mermaid diagrams by rendering images directly!
- Local renderer first! If it fails, it can fall back to an external or self-hosted rendering engine by configuring a fallback server.
- Nothing gets replaced: the preview is added below the agent's reply, so the original messages are not covered up or changed.
- Settings in Plugin page: adjust the plugin's runtime settings in the Plugins panel - no restart needed.
- Light/dark themes follow the UI automatically.
Support diagram types
The plugin renders diagrams locally with a built-in renderer. It supports 13 diagram types out of the box.
Rendered locally: flowchart, sequenceDiagram, classDiagram, stateDiagram, erDiagram, pie, journey, gitGraph, requirementDiagram, timeline, quadrantChart, packet-beta, xychart-beta
Expand: gantt, mindmap, block-beta, sankey-beta, architecture-beta, zenuml, C4Context
[!NOTE] You can enable the fallback to render expanded types — see Configuration below.
Installation
Install from github
