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-deepseek-chat

English | 中文

A DeepSeek Harness (dsh) Web UI plugin: an "Ask DeepSeek" entry on the right edge of the conversation page that opens a clean, standalone chat panel — talk to DeepSeek-V4-Flash / Pro through the API key you already configured in dsh, fully independent of the main agent session.

Features

  • 💬 Right-edge entry + floating window: a persistent vertical button opens a 4:3 floating window — drag it by the title bar, resize it from the bottom-right corner
  • 🆕 Fresh, isolated conversations: window chats never touch dsh agent sessions; one click starts over
  • 🖍️ Select-to-quote: select any text in the main conversation and a "Quote & ask DeepSeek" popover appears at its top-right — one click to ask with the quote attached
  • ⚡ Flash / Pro switch: header dropdown, with the default model persisted (localStorage)
  • 🔑 Reuses your dsh API configuration: the host half streams through ctx.llm and the registered deepseek-official route — API key, base URL and settings overrides all apply; the plugin never sees or stores any credential
  • 🌊 Streaming: SSE token-by-token output, reasoning display, cancellable at any time
  • ⚙️ Settings modal: default model, GitHub feedback link, one-click uninstall (two-step confirm)
  • 🌗 Theme aware: follows the dsh Web UI light/dark theme

Install

# From npm (once published)
dsh plugin --profile web add dsh-deepseek-chat

# Local development
git clone https://github.com/lhenlihai-hub/dsh-deepseek-chat.git
cd dsh-deepseek-chat
npm install
npm run build
dsh plugin --profile web add link:$(pwd)

Restart dsh web, open any session, and the「问 DeepSeek」entry appears on the right edge.

> Prerequisite: configure your DeepSeek API key in dsh Settings → Models first — the plugin reuses that configuration and never asks for a key itself.

Uninstall

In-panel: Settings (⚙) → Uninstall → Confirm, or from a terminal:

dsh plugin --profile web remove dsh-deepseek-chat

Restart dsh web to apply.

Development

npm install
npm run build      # emits lib/index.js (host half) + lib/client.js (browser half)
npm run watch
npm run typecheck

> Note: file: / link: installs copy rather than link — after changing sources, remove + add again (or restart dsh) for changes to take effect.
