Deep Signal for DeepSeek Harness
@thewaifu/dsh-deepsignal adds a news intelligence and U.S. market workspace
to the DeepSeek Harness WebUI. It opens as a resizable panel beside your
existing conversation, so you can follow news topics and market movement
without leaving Harness.
| Harness profile | What you get |
|---|
web | News discovery, in-plugin report reading, topic bubbles, and public U.S. stock quotes. |
Requirements
- Node.js
^22.19.0 or >=24.0.0
- DeepSeek Harness WebUI
- Internet access for news and market data
- A modern desktop browser
Check your Node.js version before installing:
node --version
If the version is lower than 22.19.0, upgrade to Node.js 22.19 or later, or
use Node.js 24.
Install and Start
Add Deep Signal to the Harness Web profile:
npx @deepseek-ai/dsh plugin --profile web add @thewaifu/dsh-deepsignal
Start the WebUI:
npx @deepseek-ai/dsh web
Open the address printed in the terminal, then select Deep Signal on the
right side of the WebUI.
If dsh is already installed globally, you can use dsh instead of
npx @deepseek-ai/dsh in every command.
Use Deep Signal
The panel contains four sections:
| Section | Availability |
|---|
| Global | Coming soon |
| News | Available |
| Stocks | Available |
| Research | Coming soon |
Drag the panel's left edge toward the left when you need more reading space.
The panel will not shrink below its initial readable width. Double-click the
resize handle to restore the default width.
Browse news
Open News to view the latest reports from the supported public news feed.
The newest reports appear first.
- Choose Today, Last 7 days, or Last 30 days to change the period.
- Select one of the ten leading topic bubbles to filter related stories.
- Larger bubbles represent topics that appear in more stories.
- Select Read brief to open the story summary inside Deep Signal.
- Select View original to read the complete Markdown report inside Deep Signal.
- Related-story actions open the corresponding brief or report directly, even
when you are browsing far down the list.
Deep Signal does not replace an unavailable feed with fabricated stories. If
the news service cannot be reached, the panel shows an unavailable state so
you can retry later.
View stocks
Open Stocks to inspect supported U.S. equities. The panel shows public
quote data, daily price movement, price ranges, and recent adjusted closing
history when the market source provides them.
Quotes may be delayed and are provided for general information only. Deep
Signal does not provide brokerage, account, or order-routing features, and
nothing in the panel is investment advice.
Language and appearance
Deep Signal follows the language selected in Harness Settings. Changing
Harness between Chinese and English updates the plugin interface and requests
the matching report language.
The plugin also follows Harness Light, Dark, and System appearance modes. It
does not store a separate theme preference.
Update
Stop the running WebUI, then run:
npx @deepseek-ai/dsh plugin --profile web update @thewaifu/dsh-deepsignal
npx @deepseek-ai/dsh web
Refresh the browser after Harness restarts. Use a hard refresh if an older
interface is still visible.
Remove
Stop the WebUI, then remove the plugin from the Web profile:
npx @deepseek-ai/dsh plugin --profile web remove @thewaifu/dsh-deepsignal
Troubleshooting
Deep Signal is missing from the WebUI
Check the Web profile:
npx @deepseek-ai/dsh plugin --profile web list
The list must contain @thewaifu/dsh-deepsignal. If it is missing, run the
install command again and restart the WebUI.
The interface did not update
Stop the old WebUI process, update the plugin, restart Harness, and hard-refresh
the browser page.
News is unavailable
Check your internet connection and retry. A temporary upstream interruption
does not affect the normal Harness conversation interface.
Installation reports EBADENGINE
Your Node.js version does not meet the package requirement. Upgrade to Node.js
