v0.8.0

@effect-uai/core

Minor Changes

• 842d92b: New WebSearch capability (additive):

  • @effect-uai/core/WebSearch: a generic WebSearch service for
    searching the live web, with a free search helper (resolve the tag,
    call .search). CommonSearchRequest is the cross-provider request
    intersection (query, maxResults, recency, startDate / endDate
    as DateTime, includeDomains / excludeDomains, country,
    language); SearchResponse carries normalized SearchResults
    (url, title, snippet, publishedDate, score) plus the raw
    provider payload. SearchRecency is "hour" | "day" | "week" | "month" | "year". A provider layer registers both the generic WebSearch tag
    and its provider-typed tag at once.
  • @effect-uai/core/WebSearchTool: webSearchTool(options?) builds a
    ready-to-use tool for the agent loop. The model only chooses query
    (and optional recency); app policy (maxResults, includeDomains /
    excludeDomains, result rendering) lives in the constructor, not the
    model arguments. The tool annotates a web_search client span.

  See Migrating to 0.8.

• 842d92b: 0.8 adds web search. A new WebSearch capability lands in core: a generic
  service for "search the live web" that providers register against, a free
  search helper, and a webSearchTool you hand to the agent loop so the
  model can ground its answers in current results. Three search providers
  debut behind it (@effect-uai/perplexity, @effect-uai/exa,
  @effect-uai/tavily), and two recipes show the patterns end to end:
  grounded answer
  (search, read, cite) and
  deep research
  (plan, fan out parallel sub-agents, synthesize a cited report).

  Like the request shape on every other capability, CommonSearchRequest
  is the cross-provider intersection (query, maxResults, recency,
  date range, includeDomains / excludeDomains, country, language);
  each provider maps what it supports and warnDroppeds the rest instead
  of silently changing your query. Cost reporting is deliberately left off
  SearchResponse for now, deferred to a unified usage-tracking pass.

  Purely additive. No migration needed. Bump dependencies, run
  typecheck, done. The new surface is in
  Migrating to 0.8.

  Every package outside core and the three new search providers
  (@effect-uai/responses, @effect-uai/anthropic, @effect-uai/google,
  @effect-uai/jina, @effect-uai/openai, @effect-uai/elevenlabs,
  @effect-uai/inworld, @effect-uai/microsandbox, @effect-uai/deno)
  has no functional changes this release; they bump for lockstep versioning
  only.

@effect-uai/exa

Minor Changes

• 842d92b: New package: @effect-uai/exa. A WebSearch provider backed by Exa's
  search API. Registers both the generic WebSearch tag and the
  provider-typed ExaSearch tag. Translates recency into a computed
  startPublishedDate, maps includeDomains / excludeDomains onto Exa's
  domain filters, and exposes the provider-typed ExaSearchType
  (auto / fast / neural / keyword / ...) and ExaCategory.
  language is warnDropped (no wire field); Exa's costDollars is kept
  on the raw payload only (cost reporting is deferred to the upcoming
  usage-tracking pass).

  excludeDomains onto search_domain_filter (exclusions via the -
  prefix), passes recency through, formats date ranges as MM/DD/YYYY,
  and maps language onto search_language_filter. Configure the search
  context size via PerplexitySearchContextSize.

  plus a relevance score, maps includeDomains / excludeDomains
  directly, and formats date ranges as YYYY-MM-DD. recency maps onto
