Dudu-0223 580496b72a feat(web): expose exa/perplexity search tuning as config
The Exa and Perplexity providers hard-coded request parameters that
deployments should control while defaults are still unsettled. Exa gains
searchType, numResults, and highlightsPerResult; Perplexity gains
maxTokens (it previously sent none) and an optional searchRecency. Each
follows the deepseek provider's shape: a defaulted Config field, a
DEFAULT_* constant, and a positive-integer status() check for numeric
limits. The call-level maxResults still flows through WebSearchRequest
and wins over the configured default, keeping the seam layering intact.

Addresses tianyicui's "make everything configurable" review comment.

@deepseek-ai/dsh-web-search-exa

An Exa-backed WebSearchProvider for the harness web capability seam (ctx.web). It calls Exa's POST /search endpoint with highlight contents and maps the flat results[] into the seam's normalized WebSearchResult.

This is an implementation package: it registers a provider into ctx.web, it does not own the ctx.web key and it does not register a model-facing tool (that is @deepseek-ai/dsh-tool-web). Like @deepseek-ai/dsh-llm-deepseek, it is a function/namespace plugin (inject: ['web']) that registers its backend, not a default-export service.

Config

Key Default Meaning
apiKey $EXA_API_KEY Exa API key. Empty/absent → provider status() reports missing-credential (the seam reports configured-unavailable/none).
baseURL https://api.exa.ai Endpoint base; /search is appended. An unparseable value makes status() report misconfigured.
searchType auto Retrieval mode sent as Exa's type: auto (Exa decides), keyword, or neural.
numResults (unset) Default result count when a request carries no maxResults. Unset sends no default. Must be a positive integer.
highlightsPerResult 1 Highlight sentences requested per result (Exa's highlightsPerUrl). Must be a positive integer.

  name: '@deepseek-ai/dsh-web-search-exa'
  config:
    apiKey: !!js process.env.EXA_API_KEY

Mapping

Exa returns a flat results[] and no generated answer, so content is omitted. Each result maps to a WebSearchSource: urlurl, titletitle, snippet ← the first non-empty highlights[] entry (a result with no highlight has no portable snippet and is dropped), publishedAtpublishedDate. A request's maxResults wins over the configured numResults default and is sent as Exa's numResults for a cost/latency optimization; the final bound is enforced by the seam. Provider failures (HTTP errors, network failure, unparseable or wrong-shape bodies) surface as WebError WEB_PROVIDER_ERROR; an aborted request surfaces as WEB_ABORTED.
