@crayonlu/dsh-web-search-tavily

Tavily-backed WebSearchProvider for the DeepSeek Harness web capability seam (ctx.web). Lets dsh's web_search tool run entirely on Tavily — no DeepSeek API key required.

Install

dsh plugin --profile web add github:crayonlu/dsh-web-search-tavily

Then add the provider to the profile patch layer at $DSH_HOME/profiles/web/cordis.patch.yml (hot-reloaded — no restart needed):

- insert:
  - id: web-search-tavily
    name: '@crayonlu/dsh-web-search-tavily'
- id: web
  config:
    searchProvider: tavily
# Optional: drop the DeepSeek-backed search (and chat route) entirely.
- id: web-search-deepseek
  disabled: true
- id: llm-deepseek
  disabled: true

Configuration

Every field is optional:

Field Default Meaning
apiKey Literal Tavily key (write it here instead of apiKeyEnv only if you must; it lands in a config file).
apiKeyEnv TAVILY_API_KEY Credential reference resolved per search through ctx.credentials (inherited env > $DSH_HOME/.credentials.yaml > project/user .env).
baseURL https://api.tavily.com Endpoint base; /search is appended.
maxResults 5 Default result count when a request carries no maxResults.
includeAnswer true Carry Tavily's generated answer as the search result content.
searchDepth basic basic or advanced (Tavily's search_depth).

The key resolves once per search, so an empty TAVILY_API_KEY fails the request with WEB_MISSING_CREDENTIAL rather than falling through to an unrelated credential.

Tests

npm install
npm test

Unit tests mock the HTTP layer; the smoke test runs a real Tavily search when TAVILY_API_KEY is set.
