dsh-session-prompt

DeepSeek Harness 插件:在每个会话的系统提示词最顶部注入自定义提示词,并可在 Web 设置页中即时编辑。

A DeepSeek Harness plugin that injects a user-configured custom prompt at the very top of every session's system prompt, editable live from the web settings page.

• 注入位置 Where it lands:每次模型请求组装系统提示词时的第一节(order: -200,位于内置身份 -100 与角色设定 0 之前)——所有会话、每一次请求。
• 界面 GUI:设置页「插件配置」标签中的一张卡片,含启用开关、多行提示词编辑、保存/放弃、恢复默认。
• 即时生效 Live:提示词文本在每次组装时读取最新设置,保存后对下一次请求立即生效,无需重启。

环境要求

• 安装了 Web UI 的 DSH 实例(含 profile 与用户设置提供方),且 dsh CLI 在 PATH 中。

安装

本包自带构建产物(lib/),从 Git 安装无需构建脚本、无需构建放行:

dsh plugin --profile <你的profile名> add github:masknull/dsh-session-prompt

该命令会链接包、记入依赖,并因包声明了 dsh.bundle 而自动加入 profile 的 bundle 列表。重启 DSH 使新的 bundle 层生效,然后打开 Web 界面。

供应链安全可固定提交:github:masknull/dsh-session-prompt#<commit sha>。

使用

1. 打开 设置 → 插件配置;
2. 展开「会话头部提示词」卡片;
3. 勾选 启用注入,编辑 提示词内容,点 保存。

说明:

• 提示词注入到每个会话(全局根 section),不是单会话。
• 关闭开关或提示词为空时不注入任何内容。
• {{…}} 限制:系统提示词渲染器会对 {{变量}} 做严格模板插值,遇到未注册或格式错误的组会直接报错;本插件会在保存时拒绝包含完整 {{…}} 组的文本,保证坏提示词永远不会弄坏请求。单独的 {{(无闭合 }})是字面量,允许。

卸载

dsh plugin --profile <你的profile名> remove dsh-session-prompt

如曾手工把配置行加进 profile 的 cordis.patch.yml,请一并删除。

从源码构建

git clone https://github.com/masknull/dsh-session-prompt
cd dsh-session-prompt
npm install          # 仅开发依赖:tsdown
npm run bundle       # 产出 lib/index.js(宿主半区)+ lib/client.js(浏览器半区)
npm run smoke        # 冒烟:验证宿主 apply() 与 section 文本 provider

lib/ 已提交进仓库;改动 src/ 后请连同重建产物一起提交。

npm run smoke 需要能解析 @deepseek-ai peer 依赖的环境(即已安装进 profile 的副本);在裸克隆中运行会给出提示而非崩溃。

目录结构

dsh-session-prompt/
├── package.json          # dsh.bundle + dsh.client 声明;运行时依赖仅为 peer
├── cordis.patch.yml      # bundle 补丁:插入插件行(含默认配置)
├── tsdown.config.ts      # 自包含的双半区构建
├── smoke.mjs             # 宿主半区冒烟测试
├── src/

│   └── client/           # 浏览器半区:设置卡片
└── lib/                  # 构建产物(已提交)

宿主半区的运行时依赖(@deepseek-ai/cordis、@deepseek-ai/schemastery、@deepseek-ai/dsh-settings)声明为 peer dependencies,由 DSH 宿主解析——插件不携带、不遮蔽宿主包。

English Documentation

Requirements

• A DSH installation that hosts the web UI (a profile and the user-settings provider must be present), and the dsh CLI on PATH.

Install

The package ships prebuilt artifacts (lib/), so a git install needs no build scripts and no build allowance:

dsh plugin --profile <your-profile> add github:masknull/dsh-session-prompt

The command links the package, records it as a dependency, and — because the package declares dsh.bundle — appends it to the profile's bundle list. Restart DSH for the new bundle layer to take effect, then open the web UI.

Optionally pin a commit for supply-chain hygiene: github:masknull/dsh-session-prompt#<sha>.

Usage

1. Open Settings → Plugin configuration.
2. Expand the Session head prompt card.
3. Toggle Enable injection and edit Prompt text, then Save.

Notes:

• The prompt is injected into every session (a root-global section), not per-conversation.
• An empty prompt, or the switch off, injects nothing.
• {{…}} restriction: the system-prompt renderer interpolates strict {{variable}} references and throws on unknown or malformed groups. The plugin refuses to save text containing a complete {{…}} group, so a bad prompt can never break requests. A lone {{ without a closing }} is literal prose and is allowed.

Uninstall

dsh plugin --profile <your-profile> remove dsh-session-prompt

If you previously hand-added the row to the profile's cordis.patch.yml, remove that entry too.

Build from source

git clone https://github.com/masknull/dsh-session-prompt
cd dsh-session-prompt
npm install          # dev-only: tsdown
npm run bundle       # -> lib/index.js (host half) + lib/client.js (browser half)
npm run smoke        # sanity-checks the host half's apply() and section provider

lib/ is committed, so contributors can change src/ and commit the rebuilt artifacts for the next release.

npm run smoke needs an environment where the @deepseek-ai peer deps resolve (i.e. the copy installed into a profile); on a bare clone it prints a hint instead of crashing.

Layout

dsh-session-prompt/
├── package.json          # dsh.bundle + dsh.client declarations, peer-only deps
├── cordis.patch.yml      # bundle patch: inserts the plugin row with default config
├── tsdown.config.ts      # self-contained build for both halves
├── smoke.mjs             # host-half smoke test
├── src/
│   ├── index.js          # host half: settings registration + head prompt section
│   └── client/           # browser half: settings card
└── lib/                  # built artifacts (committed)

The host half's runtime dependencies (@deepseek-ai/cordis, @deepseek-ai/schemastery, @deepseek-ai/dsh-settings) are declared as peer dependencies and resolved from the DSH host — the plugin never ships or shadows host packages.
