dsh-web-search-tavily

English | 中文

A Tavily-backed search provider for the DeepSeek Harness web capability seam (ctx.web): it makes the built-in web_search tool run on Tavily's search API instead of the shipped DeepSeek route.

DSH compatibility: validated with 0.2.0-rc.2.

Features

• Keyless mode - no API key needed at all: the provider sends the official X-Tavily-Access-Mode: keyless header when no key is configured. Responses are identical to keyed ones.
• Keyed upgrade - set TAVILY_API_KEY in ~/.dsh/.credentials.yaml or the environment to use the keyed tier (1,000 free credits/month at app.tavily.com). The key is resolved fresh for every search.
• Official defaults - search_depth: basic (1 credit), include_answer: false, max_results: 5, chunks_per_source: 3, per Tavily's agent guidance.

Install

dsh plugin --profile web add dsh-web-search-tavily

Then set your API key (optional - keyless mode works without one):

# ~/.dsh/.credentials.yaml
TAVILY_API_KEY: tvly-...

Select the provider (the bundle patch does this automatically; to switch manually):

# your profile's cordis.patch.yml
- id: web
  name: '@deepseek-ai/dsh-web'
  config:
    searchProvider: tavily
