A priority-ordered multi-provider web_search router for DeepSeek Harness.
The plugin registers one DSH web search provider (web-search-router) and keeps the model-facing tool unchanged: agents still call DSH's built-in web_search. Providers are tried from top to bottom and the router stops on the first successful result.
| Provider | Configuration |
|---|---|
| SearXNG | Base URL in Settings (no API key required) |
| DeepSeek Search | DEEPSEEK_API_KEY by default; the credential ref/base URL/model can be overridden in plugin config |
| Tavily | TAVILY_API_KEY |
| Brave Search | BRAVE_API_KEY |
| Exa | EXA_API_KEY |
| Firecrawl | FIRECRAWL_API_KEY |
| Parallel | PARALLEL_API_KEY |
| DuckDuckGo | No key; best-effort HTML fallback |
Unconfigured providers are skipped automatically.
Current target: DSH 0.1.0-rc.6 on Node.js 20+.
DeepSeek Harness is still a developer preview and may introduce compatibility-breaking changes. Pin the plugin revision you install and re-test when upgrading DSH.
This plugin supplies the search backend; it does not add a second model-facing tool. Your agent preset must expose DSH's built-in web_search tool (for example, the standard preset). A minimal preset that omits web_search will not invoke this router.
Local development:
dsh plugin --profile web add link:/absolute/path/to/dsh-web-search-router
From GitHub after the repository is published (pin a commit or release):
dsh plugin --profile web add github:Kerberos255/dsh-web-search-router#v0.1.0
The bundled patch selects web-search-router as DSH's search provider and inserts the plugin with generic defaults.
Open Settings → Plugins → Web Search Router to:
Non-secret settings are stored at:
$DSH_HOME/plugins/web-search-router.json
Settings writes are accepted only from loopback access. API keys are written through DSH credentials; the UI only reads configured/unconfigured state.
The plugin defaults to DSH's official DeepSeek Search provider settings. A profile may override them:
- id: web-search-router
config:
deepseekBaseURL: https://api.deepseek.com/anthropic/v1
deepseekModel: deepseek-v4-flash
deepseekApiKeyEnv: DEEPSEEK_API_KEY
The Settings UI follows the configured deepseekApiKeyEnv credential reference rather than assuming a fixed key name.
For each enabled provider, in configured order:
Caller aborts are propagated immediately and never trigger fallback.
npm test
Tests cover routing order/fallback/cooldowns, settings persistence and provider request/response adapters. Live tests used during local development are intentionally excluded from the public repository because they depend on a running local DSH instance and local credentials.
