- Derived the `SEARCH_PROVIDER_ORDER`, `SEARCH_PROVIDER_PREFERENCES`, and `SEARCH_PROVIDER_LABELS` metadata dynamically from a single `SEARCH_PROVIDER_OPTIONS` source of truth.
- Reprioritized the default search provider sequence, shifting higher-order choices like Perplexity, Gemini, and Anthropic ahead of Tavily and Brave.
- Updated documentation to reflect the new search provider evaluation order.
The runtime cutover to Kagi's V1 search API landed in #1272 but
docs/tools/web_search.md still described the sunset V0 endpoint
(GET /api/v0/search with 'Authorization: Bot ...'). Realigned the
Querying and Output bullets with the actual implementation in
packages/coding-agent/src/web/kagi.ts:
- POST https://kagi.com/api/v1/search with Bearer auth and JSON body.
- recency maps to filters.after as a UTC YYYY-MM-DD string.
- Output now includes the categorized bucket merge (search/video/news/
infobox with title tags), adjacent_question + related_search related
questions, direct_answer-derived answer, and meta.trace requestId.
Fixes#2009
Reviewer noted that an unconditional ExaProvider.isAvailable steered the auto chain into the public MCP fallback before any later-configured provider could run. Restored the credential-gated isAvailable, then split out isExplicitlyAvailable so resolveProviderChain still routes an explicit Exa selection through MCP without affecting other providers.\n\nRefs #1860
Restored Exa's unauthenticated MCP fallback when neither auth storage nor EXA_API_KEY provides credentials. Preserved API-key search ordering and bounded the MCP request with the web-search hard timeout. Updated provider copy and regression coverage for the no-key path.\n\nFixes #1860
ExaProvider.isAvailable() and searchExa() now consult AuthStorage so Exa credentials configured through the broker/credential store work alongside EXA_API_KEY, matching the other API-key search providers.
Refs #1695
- Passed ANTHROPIC_SEARCH_BASE_URL through to Anthropic web search calls that use authStorage fallback credentials instead of only applying it with ANTHROPIC_SEARCH_API_KEY.
- Added regression coverage asserting fallback Anthropic credentials use the search-specific base URL.
- Updated the environment and web_search docs to reflect the actual credential and base URL resolution order.
Fixes#1694
- Expanded the existing entries in docs/environment-variables.md so the override-semantics ('search-only, isolates from main ANTHROPIC_API_KEY / ANTHROPIC_BASE_URL / FOUNDRY_BASE_URL') are spelled out, and added a usage note for enterprise-gateway split routing.
- Surfaced the search-only env vars (ANTHROPIC_SEARCH_API_KEY / ANTHROPIC_SEARCH_BASE_URL / ANTHROPIC_SEARCH_MODEL) in the Anthropic provider section of docs/tools/web_search.md, where users were already looking.
- Added ANTHROPIC_SEARCH_BASE_URL alongside ANTHROPIC_SEARCH_API_KEY in 'omp --help' so the pair shows up together in the CLI env-var summary.
