Every credential-free engine is excluded by settings.

Error message

Every credential-free engine is excluded by settings.

What it means

The Public Web aggregate fans out to a fixed set of credential-free engines (startpage, google, duckduckgo, ecosia, mojeek). If settings exclude every one of them, there is nothing to fan out to, so searchPublicWeb throws a SearchProviderError (status 400) before making any network calls.

Thrown at packages/coding-agent/src/web/search/providers/public.ts:126

 * The fan-out races three exits and returns at the earliest: every engine
 * settled; the soft deadline elapsed with at least one success in hand; the
 * hard deadline elapsed regardless. If the soft deadline fires before any
 * engine has delivered, the aggregate keeps waiting (up to the hard cap) for
 * the first success, so a slow field degrades to fewer engines rather than
 * an empty answer. Stragglers are aborted once the race resolves. Individual
 * engine failures (bot challenges, timeouts) are tolerated; the call fails
 * only when every engine fails.

Solutions

Re-enable at least one credential-free engine in settings (remove it from the exclusion list)
Inspect search provider exclusion settings for overly broad entries
Switch the search call to a credentialed provider (Perplexity, Parallel) instead of the public aggregate

Example fix

// before (settings)
{ "search": { "excludeProviders": ["startpage","google","duckduckgo","ecosia","mojeek"] } }
// after
{ "search": { "excludeProviders": ["ecosia"] } }

Defensive patterns

Strategy: validation

Validate before calling

import { isSearchProviderExcluded } from "./web/search/provider";
const engines = ["startpage","google","duckduckgo","ecosia","mojeek"];
if (engines.every(id => isSearchProviderExcluded(id))) {
  throw new Error('Enable at least one credential-free engine before public web search');
}

Try / catch

try {
  return await searchPublicWeb(params);
} catch (err) {
  if (err instanceof SearchProviderError && err.statusCode === 400 && err.message.includes("excluded by settings")) {
    return credentialedProviderSearch(params);
  }
  throw err;
}

Prevention

Never exclude every engine in the credential-free set
Audit copied settings templates for wholesale exclusion lists
Keep one default engine always enabled

When it happens

Trigger: Calling the public web search while every PUBLIC_ENGINE_IDS entry is excluded via provider exclusion settings (isSearchProviderExcluded returns true for all five).

Common situations: User disabled individual engines after bot-challenge complaints and accidentally excluded all of them; a config template copied exclusion lists verbatim; settings file listing all engines under an exclusion key.
