@lp181818/web-search-advanced

Advanced web search plugin for DeepSeek Harness (DSH), supporting both native DeepSeek search and OpenAI-compatible "Custom" search providers.

Features

• Provider selector: deepseek (native) or custom (OpenAI-compatible, e.g. OpenRouter)
• Settings section: provider choice, endpoint URL, model, API key, max searches
• Two search backends: native DeepSeek web_search_20250305 or an OpenAI-compatible web plugin
• Automatic retry (v0.1.4): transient failures (HTTP 429 / 5xx / network errors) are retried with exponential backoff, honoring the server Retry-After header (configurable maxRetries, default 3)
• Test before save (v0.1.4): the settings card probes the configured endpoint (/chat/completions for Custom, /messages for DeepSeek) with the current draft values before saving; real config errors (bad endpoint/model/key) block the save, transient 429/5xx only warn

DSH compatibility

DSH version	Compatibility
0.1.2-rc.1 and current 0.1.2 rc	Registers and exposes the settings namespace through the current settings/LLM services
0.1.0-rc.7 through pre-0.1.2-alpha	Uses the shared settings.register/installSection service API; theoretically compatible
before 0.1.0-rc.7 / 0.0.x	Not supported; those DSH versions lack the settings/section mechanism

The current source no longer imports the removed settingsNamespace, installSettingsSection, or @deepseek-ai/dsh-client-runtime APIs.

Enabling this provider in DSH

Installing this package automatically routes the DSH web service to web-search-advanced; no manual cordis.patch.yml edit is required. After installation, restart dsh web and configure the package in the Web Search settings section.

Only the provider, API key, and model are required. The endpoint is optional: DeepSeek uses https://api.deepseek.com/anthropic/v1, while Custom uses https://openrouter.ai/api/v1 when the endpoint is left blank. Inside the web-search-advanced settings namespace:

• searchProvider: deepseek uses this plugin's DeepSeek branch.
• searchProvider: custom uses the configured OpenAI-compatible baseURL / model, for example OpenRouter.
• maxRetries: 3 (optional) — exponential-backoff retries for transient failures (429 / 5xx / network), default 3.

Settings persist in ~/.dsh/settings.yaml under the web-search-advanced namespace and survive DSH restarts until deleted.

The package patch also selects the built-in http fetch provider so search results can be opened without an additional profile change.

Build

This repository includes the prebuilt lib/ artifacts required by DSH skill hub validation. Direct GitHub installs also have a prepare script that can rebuild them.

DSH resolves @deepseek-ai/* packages as runtime peers, so local installs should not make npm resolve them:

▼
powershell
复制代码
npm install --legacy-peer-deps
npm run build

Build output:

• lib/index.js - DSH host/plugin half
• lib/client.js - DSH web client bundle

After a build, sync into an installed DSH profile:

▼
powershell
复制代码
npm run sync

If no profile has the package installed yet, install it first:

▼
powershell
复制代码
dsh plugin --profile web add github:bug-huntter/web-search-advanced

Then restart DSH and apply the profile patch:

▼
powershell
复制代码
dsh web

The plugin registers its provider through ctx.web, registers the web-search-advanced settings namespace, and exposes that namespace to the web client through the configurable-provider registry.
