- Preserve abort errors while parsing search responses: when the caller's AbortSignal fires after headers but during response.json() (both the success and HTTP-error body parses), surface WEB_ABORTED instead of wrapping it as WEB_PROVIDER_ERROR, so agent cancel/dispose is not misreported as a provider failure. Applied to both the Exa and Perplexity providers. - Report a malformed baseURL as misconfigured in status() (URL.canParse), so selection diagnostics and execution agree (configured-unavailable up front rather than a late WEB_PROVIDER_ERROR). WebProviderStatus already had the reason.
@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. |

Mapping
Exa returns a flat results[] and no generated answer, so content is omitted. Each result maps to a WebSearchSource: url ← url, title ← title, snippet ← the first non-empty highlights[] entry (a result with no highlight has no portable snippet and is dropped), publishedAt ← publishedDate. The provider passes maxResults through as Exa's numResults for a cost/latency optimization; the final bound is enforced by the seam. Provider failures (HTTP errors, network failure, unparseable bodies) surface as WebError WEB_PROVIDER_ERROR; an aborted request surfaces as WEB_ABORTED.
