dsh-web-search-opencli

Use Google AI Mode as a DeepSeek Harness web_search provider through OpenCLI.

dsh-web-search-opencli registers a DSH ctx.web search provider. When an agent calls web_search, the plugin drives your existing Chrome or Edge browser through OpenCLI, opens Google Search AI Mode (udm=50), waits for the AI answer, extracts the answer and cited source URLs, and returns DSH's standard WebSearchResult.

Features

• Google AI Mode answers exposed through DSH web_search.
• OpenCLI browser automation instead of a scraped HTTP endpoint.
• Source URL extraction from AI Mode citations and links.
• Markdown conversion for the AI answer body.
• Reuses the configured OpenCLI browser session tab by default.
• Configurable provider id, OpenCLI command/session/window mode, timeout, and best-effort tab cleanup.

Requirements

• Node.js ^22.19.0 || >=24.0.0.
• A DeepSeek Harness install that provides @deepseek-ai/dsh-web.
• OpenCLI installed and connected to its browser extension.
• Chrome or Edge signed in to a Google account that can use AI Mode.
• Google AI Mode available for the browser account, region, and locale.

The provider uses the current browser profile. It does not read or store Google cookies.

Verify OpenCLI first:

opencli doctor

Install

Preferred npm install:

dsh plugin --profile web add dsh-web-search-opencli

From a DeepSeek Harness source checkout, use the checkout wrapper:

pnpm dsh plugin --profile web add dsh-web-search-opencli

Before npm publication, install from GitHub:

dsh plugin --profile web add github:sincerity711/dsh-web-search-opencli

For local development:

git clone https://github.com/sincerity711/dsh-web-search-opencli.git
cd dsh-web-search-opencli
npm install
npm run build

dsh plugin --profile web add /path/to/dsh-web-search-opencli

The package includes built lib/ artifacts in npm releases. GitHub installs run the package prepare script to build them.

Bundle patch

The package includes cordis.patch.yml, so the normal plugin install can apply this default web-profile patch:

- id: web
  config:
    searchProvider: google-ai-mode

- insert:
    - id: web-search-opencli
      name: dsh-web-search-opencli
      config:
        providerId: google-ai-mode
        opencliSession: dsh-google-ai-mode
        opencliWindow: background
        timeoutMs: 45000
        closeTabAfterSearch: false

If you manually edit a profile patch, preserve any existing web config fields you still need. A patch replaces the targeted row's whole config.

Verify

Dump the resolved web profile:

dsh --profile web --dump-config

The output should include:

- id: web
  name: '@deepseek-ai/dsh-web'
  config:
    searchProvider: google-ai-mode

and:

- id: web-search-opencli
  name: dsh-web-search-opencli
  config:
    providerId: google-ai-mode

Restart DSH Web after changing the profile:

dsh web

Architecture reference

See docs/architecture.md for the runtime flow, provider registration, OpenCLI command sequence, extraction pipeline, and error mapping.

Config

Field	Default	Meaning
providerId	google-ai-mode	Provider id registered into ctx.web.
opencliCommand	opencli	Executable name or path.
opencliSession	dsh-google-ai-mode	OpenCLI browser session used for Google tabs.
opencliWindow	background	Value passed as both OPENCLI_WINDOW and OpenCLI --window for browser commands.
timeoutMs	45000	Per-search timeout budget in milliseconds.
closeTabAfterSearch	false	Optional best-effort tab close after each search. Disabled by default because Chrome can replace the final tab in OpenCLI's automation window with about:blank.

Behavior

• content contains the Google AI Mode answer converted to markdown.
• sources[] contains URLs cited or linked by the AI Mode answer.
• Duplicate source URLs are collapsed in first-use order.
• Ordinary Google search results outside the AI Mode answer are not used as a fallback.
• DSH ctx.web enforces maxResults after the provider returns.
• The default background OpenCLI window mode avoids stealing focus.
• The provider reuses its OpenCLI automation tab by default. Set closeTabAfterSearch: true only if you prefer best-effort tab cleanup.

Errors

The provider throws DSH WebError values:

• WEB_SEARCH_OPENCLI_CAPTCHA: Google showed a CAPTCHA or unusual-traffic page.
• WEB_SEARCH_OPENCLI_AI_MODE_UNAVAILABLE: AI Mode is unavailable for the current account, region, or language.
• WEB_SEARCH_OPENCLI_TIMEOUT: the OpenCLI operation exceeded timeoutMs.
• WEB_PROVIDER_ERROR: OpenCLI failed or extraction returned an unexpected result.
• WEB_ABORTED: the DSH call was cancelled.

Troubleshooting

Searches fail with OpenCLI errors

Run opencli doctor, then make sure Chrome or Edge is open and the OpenCLI browser extension is connected.

Google asks for CAPTCHA

Open Google manually in the browser, solve the CAPTCHA, and retry the DSH search.

AI Mode is unavailable

Google AI Mode availability depends on the account, region, and locale. Sign in with an account that can access AI Mode, or switch back to another DSH web search provider.

Concurrent searches fail with detached browser errors

OpenCLI browser sessions are stateful. Avoid running concurrent searches against the same opencliSession. Use separate session names or serialize searches if you need parallelism.

Community plugin discovery

This repository is prepared for the current DeepSeek Harness community plugin discovery flow. Add these GitHub topics to the public repository:

dsh-plugin
deepseek-harness
dsh
web-search
opencli

The npm package carries matching keywords and declares the DSH bundle patch.
