This evidence comes from the upstream catalog. This site has not installed, run, or security-reviewed the plugin.

Install

Start with a prompt that asks an agent to review the GitHub repository and source. Switch to the command if you want to install it yourself.

Copy this prompt into DSH, Codex, or another agent and ask it to review the GitHub repository and source first.

Do not install or run any commands yet. Read this plugin's GitHub repository, README, and relevant source code. Then answer the questions below clearly and directly so I can decide whether it fits my needs:

1. What is this plugin, and what problem does it solve?
2. Who is it for, and what are its typical use cases?
3. How is it used after installation? Include one minimal example.
4. What known limitations or privacy, security, compatibility, or maintenance risks does it have?
5. Give a clear recommendation: recommend, conditionally recommend, or do not recommend, with reasons.

Distinguish statements documented by the repository, inferences from source code, and unknowns. If evidence is insufficient, say so explicitly. Do not guess or simply repeat the README.

dsh-html-artifact

HTML 实时渲染插件:模型通过专门的 artifact 工具创建/修补 HTML 文档,GUI 在沙箱 iframe 里实时渲染。核心区别:模型打 patchold_string/new_string,和文件 edit 工具同一套语义),而不是每次重发整个 HTML —— 只传增量,预览原地更新。

纯扩展实现,不改 harness core

  • 服务端:artifact 工具(create / patch / read / destroy / list),per-session 注册表;card: 'artifact' 渲染意图通过 presentResult 走线(core 的 union 不认识这个 card,返回值做了边界强转,客户端未知 card 自动降级 generic)。
  • 客户端:tool.call.toolview keyed slot 注册 artifact 行的原子视图,沙箱 iframe(CSP default-src 'none' + sandbox="allow-scripts" 不透明源 + 主题变量 + 尺寸桥 + 存储 shim),同一 artifact id 的后续 patch 调用原地更新预览。

安装

发布版走 GitHub Releases 的 tarball(dsh plugin 安装后自动加入 profile 层栈),releases/latest 永远指向最新版本,链接不用随版本改动:

dsh plugin --profile web add "https://github.com/lehhair/dsh-html-artifact/releases/latest/download/dsh-external-dsh-html-artifact.tgz"

然后重启 dsh web 服务,刷新页面。不要dsh plugin add github:lehhair/dsh-html-artifact 安装源码(仓库的 lib/ 被 gitignore,源码安装没有构建产物)。

> ⚠️ 升级注意:pnpm 会按 URL 缓存 tarball——同一 latest 链接在新版本发布后可能命中旧缓存。装到旧版时先 dsh plugin --profile web remove @dsh-external/dsh-html-artifact 再重新安装(必要时 pnpm store prune)。

用法

模型侧(工具描述已内置):

1. artifact create { title?, html? } —— 创建,GUI 立即渲染沙箱预览。 2. artifact patch { id, old_string, new_string, replace_all? } —— 对已有 artifact 打补丁,只发变更;每个 patch 调用结算后预览原地更新,会话里显示一行旧/新对比。 3. artifact read { id } / artifact destroy { id } / artifact list —— 读取源码 / 关闭 / 枚举。

安全边界:预览在 srcdoc iframe 中,CSP default-src 'none'(脚本/样式允许内联,外部 https/http 资源允许),iframe 无 allow-same-origin(不透明源),artifact 脚本无法触达宿主文档;localStorage/sessionStorage 被内存 shim 替代。

交互数据提交

预览底部 Submit interaction 按钮会把用户在 artifact 内的交互数据注入当前会话(Agent.followup,agent 立即读取分析)。收集三层:

1. 显式协议(推荐,游戏/计数器等内部状态):artifact 脚本把值得提交的状态写成 JSON 值并随状态变化更新: ``js window.__dshArtifactData = { score: currentScore, moves: moves } ` 工具描述里已内置该指令,模型生成带内部状态的 artifact 时会自动写。 2. 表单控件(自动)input / textarea / select / checkbox / radio 的当前值按 name/id 收集。 3. 按钮点击(自动):点击过的按钮(data-artifact-action` 优先,否则按钮文本)与次数自动记录。

开发

pnpm install        # devDeps 是 link: 到 ../dsh2026/deepseek-harness 的本地 checkout
pnpm run check      # typecheck + test + build

测试:tests/registry.spec.ts(服务端纯逻辑:替换语义、字节上限、截断、错误分类)+ tests/artifact-row.spec.tsx(客户端渲染:沙箱 iframe、patch 对比、跨调用实时更新、destroy/list/read 分支)。

CI(.github/workflows/build-release.yml):发布时 checkout 固定 ref 的 harness 构建后打包 tarball 上传到 Release。注意:同 URL 重建 release 会命中 pnpm 的 URL 缓存,出新版本务必 bump version。
