@your-scope/dsh-mode-switcher

One-tap collaboration-mode capsules above the composer — flip the session between Plan (the official plan mode), Review and Quick-Answer modes, with guidance adapted from OpenAI Codex's own mode templates. DeepSeek Harness Web UI 的「模式切换器」——输入框上方一排胶囊，一键在 Plan（官方）/ 审查 / 快答三种协作模式间切换。

Features

Mode capsules above the composer — Plan · Review · Quick; click to switch, click again to leave. The active capsule stays lit.
Drives the official plan mode, not a reimplementation: the Plan capsule executes /plan / /plan off through the commands channel and reads the host-computed plan projection (the official Plan chip, composer placeholder and exit_plan_mode flow all follow). On deployments without plan mode the capsule simply hides.
Two custom modes, adapted from OpenAI Codex's prompt assets (Apache-2.0):
- Review — from Codex's review rubric: read-only senior-reviewer stance, findings first, severity tags [P0]–[P3], explicit "looks good" when nothing qualifies, one-line overall verdict.
- Quick — from Codex's default collaboration mode: answer first, reasonable assumptions over clarifying questions, minimal tool calls, no edits unless asked.
Log-only state — switching appends a modeswitch/mode session event and the last one wins, exactly like the official plan mode: the mode survives reloads, resumes and forks, and other surfaces (CLI, another tab) agree with what you see.
Prompt-section injection — the active mode's guidance renders as the modeswitch:policy system-prompt section on every request (verifiable in the session log's request/header).
Slash command too — /mode review, /mode quick, /mode off, or bare /mode to ask. Bilingual UI (zh/en) follows the app locale.

Install

From source (npm package coming soon):

git clone https://github.com/Horizon215/dsh-plugins.git
cd dsh-plugins
pnpm install && pnpm build
dsh plugin --profile web add file:./packages/mode-switcher

Restart dsh web. The package declares dsh.bundle, so it joins the profile automatically — no config edits.

Notes

Requires dsh ≥ 0.1.0-rc.5, web UI only.
This is a hybrid plugin: the host half registers the /mode command and the prompt section; the browser half is just the capsule bar. The host half has zero runtime imports — everything goes through cordis services.
Custom-mode guidance is English (matching the deployment's other prompt sections); the model still mirrors your language in replies.
Plan and a custom mode can be active at once (e.g. plan + review); they're independent layers, same as upstream.

Uninstall

dsh plugin --profile web remove @your-scope/dsh-mode-switcher

功能

输入框上方的模式胶囊 —— Plan · 审查 · 快答，点一下切换，再点一下退出，激活胶囊常亮。
驱动官方 Plan 模式而非重造：Plan 胶囊通过命令通道执行 /plan / /plan off 并读取宿主计算的 plan 投影（官方 Plan 芯片、输入框占位文案、exit_plan_mode 流程全部跟随）。部署里没有 plan 模式时该胶囊自动隐藏。
两个自定义模式，改编自 OpenAI Codex 的提示词资产（Apache-2.0）：
- 审查 —— 源自 Codex 的审查 rubric：只读的高级审查员立场，发现优先、按 [P0]–[P3] 严重度标记、没有合格发现就明说"看起来没问题"、结尾一行总体结论。
- 快答 —— 源自 Codex 的默认协作模式：先给答案、合理假设优于追问、最少工具调用、不让改就不改。
状态只落在日志 —— 切换即追加 modeswitch/mode 会话事件、最后一条生效，与官方 plan 模式同一架构：刷新、恢复、分叉后模式都在，其他端（CLI、另一个标签页）看到的状态一致。
提示词段注入 —— 激活模式的指导作为 modeswitch:policy 系统提示词段出现在每次请求里（可在会话日志的 request/header 中验证）。
也支持斜杠命令 —— /mode review、/mode quick、/mode off，或裸 /mode 查询当前模式。界面中英双语跟随应用语言。

安装

从源码安装（npm 包即将推出）：

git clone https://github.com/Horizon215/dsh-plugins.git
cd dsh-plugins
pnpm install && pnpm build
dsh plugin --profile web add file:./packages/mode-switcher

重启 dsh web。包已声明 dsh.bundle，会自动加入 profile，无需改配置。

说明

需要 dsh ≥ 0.1.0-rc.5，仅 Web UI。
这是一个混合插件：宿主半注册 /mode 命令和提示词段，浏览器半只有胶囊条。宿主半零运行时导入——一切都走 cordis 服务。
自定义模式的指导文本是英文（与部署里其他提示词段一致）；模型回复仍跟随你的语言。
Plan 与自定义模式可以同时激活（例如 plan + 审查），二者是独立层，与上游一致。
