dsh-web-search-tavily

A Tavily-backed search provider bundle for DeepSeek Harness (dsh). It registers a Tavily backend for the ctx.web web-search seam and ships a hot-switchable backend selector (Tavily / DeepSeek search).

Features

• Tavily provider — calls POST /search and normalizes results to { url, title, snippet, publishedAt }. Tavily returns content excerpts, so the model can quote snippets directly.
• Hot backend switcher — a delegating provider (search-switch) sits behind the web row and resolves the active backend from the web-search settings section on every search. Saving the section takes effect immediately: no restart, no loader-row reload.
• Full WebError taxonomy (WEB_PROVIDER_ERROR / WEB_PROVIDER_CREDENTIAL_MISSING / WEB_ABORTED).
• Credential resolution chain: literal apiKey → credentials service → launch environment.
• Settings sections:
  • web-search-tavily — apiKey / apiKeyEnv / baseURL / maxResults
  • web-search — backend selection (tavily | deepseek-official)
