dsh-webchatlike

把 DeepSeek 网页版 / App 的聊天体验带进 DeepSeek Harness：编辑提问、重新生成回复、在消息上直接翻版本——就像在 deepseek.com 上聊天一样。

一个面向 DeepSeek Harness Web GUI 的客户端插件,让对话行为和 deepseek.com 网页版 / App 一致:原位编辑、一键重新生成、逐条消息的版本翻页器。

• ✏️ 编辑重发——悬停自己的消息,在原消息位置就地打开编辑框(预填原提问,无弹窗、不新建对话),改完重发。fork 点选在提问回合之前,新会话是干净的 历史 + 修改后的提问 + 新回答。
• 🔄 重新生成——悬停任意 assistant 回复,从该回合之前分叉重新生成。旧提问不会重复塞进上下文。
• <i/N> 版本翻页——每条被重新生成 / 编辑重发过的消息旁都会出现 deepseek.com 风格的 <2/5> 翻页器(树状模型:每条消息的版本独立计数)。左右箭头切换版本,自动定位到同一轮。每个对话记住你最后查看的版本——切去别的对话再回来,不会跳回第 1 版。
• 🌳 分叉整棵树——「在新对话中分支」(对话内或边栏)会把整棵树复制成一份完全独立的副本:新根 + 每个版本的副本,新树自带完整版本体系(<i/N> 可翻),从此与原树互不影响。副本根标题带 (副本) / (副本 2) 递增,分叉后自动定位到你 fork 时所在的版本。任意侧边栏 / 对话内分叉出来的独立副本(包括非版本族会话的单会话分叉)都带 (副本) 标记——它是边栏区分"独立副本"与"regenerate/编辑版本"的记号,保证新副本一定以独立行出现,不会被折叠隐藏。
• 🗑️ 删除会话(需补丁)——从左侧会话菜单彻底删除会话,连同硬盘上的会话日志。

边栏保持干净:版本 fork 折叠进原始对话(一个对话一行),在任意版本里的活动都会照常把该对话浮到顶部。家族根行上的重命名、归档、删除作用于整棵树(所有 regenerate/编辑版本);分叉副本是完全独立的对话,只作用于自身。

⚠ 依赖 2 个源码补丁

与纯插件不同,本插件扩展了两个 harness 没有公开扩展点的源码文件:

不打补丁时插件能加载,但编辑按钮和边栏折叠不会出现。cordis.patch.yml 只负责加载插件本身。

安装

1. 打源码补丁

cd deepseek-harness
/path/to/dsh-webchatlike/apply-patches.sh   # 逐个复制,冲突时提示
pnpm install
pnpm run build:lib:client && pnpm run build:web

2. 安装插件

方式一:作为 bundle 安装(已声明 dsh.bundle):

dsh plugin --profile web add <本仓库 git 地址或 npm 包名>

方式二:手动在 ~/.dsh/profiles/web/cordis.patch.yml 注册:

- insert:
    - id: chat-actions
      name: 'dsh-webchatlike'

手动安装时,请把包加入 ~/.dsh/profiles/web/package.json 的 dependencies 并在 profile 目录执行 pnpm install,让加载器能解析到它。

3. 重启

终端 Ctrl+C,重新 pnpm dsh web,刷新页面。

使用

• 悬停任意 assistant 回复 → 🔄 重新生成
• 悬停任意 用户消息 → ✏️ 原位编辑重发
• 对同一回合多次 🔄 / ✏️ 后,回复旁出现 <2/5>,点左右箭头切换版本
• 左侧会话列表行尾 ⋯ 菜单 → 删除会话(带确认框;正在运行的会话拒绝删除)

工作原理

• 每个版本都是一个真实的 fork 会话。fork 点选在目标回合之前,新会话 = 历史 + 提问 + 新回答——与 deepseek.com 的树状模型一致。
• 插件把 fork 记录在 localStorage 版本树(dsh-webchatlike:version-tree,按家族根命名空间:每棵树一个命名空间,分叉副本与原树互不干扰)和「最后查看版本」映射(dsh-webchatlike:last-version)里。所有读取都是防御式的:没有插件时,边栏行为与原生完全一致。
• 版本翻页器渲染在每条版本化消息上;切换打开兄弟 fork 并滚动定位到同一轮。不依赖 seedLength——版本功能不需要任何 host 改动。

FAQ

为什么对话的第一条消息没有按钮? 第一回合之前没有干净的 fork 边界(harness 的 fork 需要一个已完成的回合作为锚点),所以第一条消息不能重新生成 / 编辑——和大多数网页版聊天一致。

与上游的关系

• 插件本身只用 harness 公开扩展点(conversation.chat.assistant-actions / conversation.chat.user-actions 插槽、ctx.sessions.fork、session.prompt、ctx.sessions.open)。
• 两个补丁是小而自洽的核心改动(共 9 个文件)。上游更新后重新应用即可——apply-patches.sh 会先对比再覆盖。

dsh-webchatlike

Bring the DeepSeek web / app chat experience to DeepSeek Harness: edit your question, regenerate the answer, and flip between versions — right on the message, like chatting on deepseek.com.

A client plugin for the DeepSeek Harness Web GUI that makes conversations behave like the deepseek.com web/app chat — in-place editing, one-click regeneration, and a per-message version pager.

• ✏️ Edit & resend — hover your own message, edit it in place (no modal, no new chat), and resend. A clean fork restarts from the turn before your question: history + edited question + new answer.
• 🔄 Regenerate — hover any assistant reply and regenerate it from the turn before. The old question is not duplicated into context.
• <i/N> Version pager — every message whose turn was regenerated or edited gets a deepseek.com-style <2/5> pager (tree model: each message's versions are counted independently). Flip through versions with the chevrons; the same turn is scrolled into view. The version you were viewing is remembered per conversation, so switching chats and coming back does not throw you to version 1.
• 🌳 Fork the whole tree — "Branch in a new conversation" (in-chat or sidebar) copies the WHOLE tree into a fully independent copy: a new root plus a copy of every version, with its own complete version system (<i/N> pager works), never interacting with the source again. The copy root is titled base (副本) / (副本 2) etc., and the new tree opens at the version you forked FROM. Every independent copy created by the sidebar or in-chat fork action (including plain single-session forks outside any version family) carries the (副本) marker — the sidebar's tell that distinguishes an independent copy from a regenerate/edit version, so a new copy always shows up as its own row and is never folded away.
• 🗑️ Delete session (patch) — delete a session from the sidebar context menu, including its on-disk log.

The sidebar stays clean: version forks are folded into their original conversation (one row per conversation), and activity inside any version still floats that conversation to the top. Family-ROOT rows act on the whole tree for rename/archive/delete (all regenerate/edit versions); fork copies are fully independent conversations that only ever act on themselves.

⚠ Requires 2 source patches

Unlike pure plugins, this one extends two harness source files that have no public extension points:

Without them the plugin loads but the edit button and sidebar folding stay off. cordis.patch.yml only loads the plugin itself.

Install

1. Apply the source patches

cd deepseek-harness
/path/to/dsh-webchatlike/apply-patches.sh   # copies files, prompts on conflicts
pnpm install
pnpm run build:lib:client && pnpm run build:web

2. Install the plugin

Either install it as a bundle (it declares dsh.bundle):

dsh plugin --profile web add <this-repo-git-url-or-npm-name>

…or register it manually in ~/.dsh/profiles/web/cordis.patch.yml:

- insert:
    - id: chat-actions
      name: 'dsh-webchatlike'

If you install manually, make the package resolvable from the profile (e.g. add it to ~/.dsh/profiles/web/package.json dependencies and pnpm install there).

3. Restart

Ctrl+C and pnpm dsh web again, then refresh the browser.

Usage

• Hover an assistant reply → 🔄 to regenerate.
• Hover a user message → ✏️ to edit in place and resend.
• After several 🔄/✏️ on the same turn, the reply shows <2/5>; use the chevrons to switch versions.
• Sidebar row ⋯ menu → Delete session (with confirmation; running sessions are refused).

How it works

• Every version is a real fork session. The fork cut lands before the target turn, so the new session is history + question + new answer — matching deepseek.com's tree model.
• The plugin records forks in a localStorage version tree (dsh-webchatlike:version-tree, namespaced by family ROOT — each tree gets its own namespace, so forked copies never collide with the source), and the "last viewed version" map (dsh-webchatlike:last-version). Reads are fully defensive: without the plugin the sidebar behaves exactly as stock.
• The version pager renders on every versioned message; switching opens the sibling fork and scrolls the same turn into view. seedLength is not used — no host changes needed for versioning.

FAQ

Why are there no buttons on the very first message of a conversation? The first turn has no clean fork boundary before it (the harness fork needs a completed turn to anchor to), so regenerate/edit are unavailable there — same as the first message in most web chats.

Relationship to upstream

• The plugin itself uses only harness public extension points (conversation.chat.assistant-actions / conversation.chat.user-actions slots, ctx.sessions.fork, session.prompt, ctx.sessions.open).
• The two patches are small, self-contained core changes (9 files total). Re-apply after upstream updates — apply-patches.sh diffs and asks before overwriting.
