fix(web-search): opt-in hosted web-search bridge for the key-auth Responses passthrough - #4142
Conversation
…m, and guard fallback
📝 WalkthroughWalkthroughThis change adds an opt-in Ollama web-search bridge for key-auth Responses passthrough providers. It validates provider settings, executes intercepted searches, continues upstream conversations, rewrites streamed events, and adds comprehensive tests. ChangesWeb-search bridge
Priority: ➖ Normal Estimated code review effort: 4 (Complex) | ~60 minutes Severity of issue fixed: Medium Merge Risk: 🟡 Moderate · up to Enabled bridge turns can expose credentials on plaintext endpoints, produce inconsistent terminal search state, or fail continuation requests. These issues should be resolved before merging unless the bounded opt-in risk is explicitly accepted. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

Inline comments:
In `@docs-site/src/content/docs/reference/configuration/providers.md`:
- Line 187: The webSearchBridge documentation is inconsistent with the shipped
backend union and planner behavior. Update the type column to list ollama,
anthropic, xai, gemini, and exa, and revise the description to remove the
unsupported exclusion for providers that execute hosted search, matching
planPassthroughWebSearchBridge behavior.
In `@src/config.ts`:
- Line 535: Require HTTPS-only URLs in the validation surrounding the protocol
check, rejecting http endpoints for credential-bearing requests. Update every
related validation message and user-facing description in this configuration
flow to refer to HTTPS, without adding local cleartext support.
In `@src/server/responses/core.ts`:
- Line 5799: Keep continuation request bodies separate from credential refresh:
remove oauthDispatch(request) from continuation sends so existing
function_call_output content is preserved. Update createOllamaBridgeExecutor or
the bridge send path to resolve the current provider API key and executor at
send time, including after key rotation. Add a regression test rotating the key
between legs and asserting both the preserved function_call_output and current
search credential.
- Line 5794: Before constructing the continuation request in the responses
passthrough flow, remove transport-specific content-length and content-encoding
metadata from the headers copied from provider configuration. Ensure the request
using continuationBody sends sanitized headers while preserving all other
configured headers and the existing continuation behavior.
- Around line 5791-5800: The continuation send callback near
fetchWithHeaderTimeout must use the same bounded upstream retry policy as the
initial fetchWithTransientRetry path. Wrap each continuation attempt with
applyUpstreamRecoveryInit using the appropriate recovery kind, preserve
continuationBody as the request body, and retain the existing provider and OAuth
dispatch configuration without adding credential refresh or body replacement.
In `@src/web-search/passthrough-bridge.ts`:
- Around line 503-505: Update the response.failed/response.incomplete terminal
path in decide to return the active this.searches instead of an empty list, then
update the end branch of bridgeStreamBlocks to emit searchEndFrames before
terminalFrames so injected search cells are closed and retained in the terminal
snapshot. Add a regression test in the existing passthrough bridge
stream-rewrite tests covering a search followed by response.failed and asserting
both output_item.done and the terminal response.output entry.
- Line 628: Sanitize caught error text before assigning it to client-visible
failure responses in both the upstream-read and continuation-send handlers.
Update the error-message construction near the existing Error/String conversion
and the corresponding handler around failureFrames so response.failed.error and
response.failed.last_error receive the established redacted form, matching
existing web-search response paths.
- Line 88: Require HTTPS in both the endpoint validator in passthrough-bridge.ts
and the corresponding configuration validator, rejecting HTTP by default while
allowing plaintext only for loopback hosts if supported. Preserve acceptance of
HTTPS endpoints and ensure the explicit endpoint path used by runOllamaWebSearch
cannot send credentials to non-loopback HTTP targets.
In `@tests/web-search/web-search-passthrough-bridge.test.ts`:
- Around line 171-179: Extend the test “out-of-range bounds fall back to the
documented defaults” to also verify that the planner accepts the documented
upper bounds: maxSearches 10 and timeoutMs 600_000 must remain configured rather
than defaulting to 3 and 60_000. Keep the existing invalid-value fallback
assertions.
- Around line 511-521: Add an executor-level regression test using the real
Ollama web-search execution path rather than stubbing execute, with an upstream
error body or thrown error containing the provider API key; assert the
continuation output excludes the key and includes “[redacted-provider-key]”,
while preserving the failed web-search status assertions.
- Around line 584-589: Update the web-search passthrough test mock to capture
each outbound request URL and Authorization header, replace the substring check
with an exact endpoint match, and assert the resolved default endpoint receives
the expected bearer key. Add coverage for explicitly configured http and https
endpoints, verifying each request targets the configured origin and carries the
provider key.
- Around line 314-315: Strengthen the sequence validation in the test around the
sequences mapping so every event has a numeric sequence_number and the values
increase strictly in emission order. Retain the existing ordering check only if
needed, but ensure missing or non-increasing values cause the test to fail.

| | `terminalContinuationGuard?` | `boolean` | Opt in an `openai-chat` provider to one bounded internal re-ask when an actionable turn announces work, then cleanly stops without a tool call.

Function-call ids are never rewritten. Built-in DeepSeek enables the last two by default. | | ||

| | `webSearchBridge?` | `{ enabled?: boolean; backend?: "ollama"; maxSearches?: number; timeoutMs?: number; endpoint?: string }` | Key-auth `openai-responses` passthrough providers only. Off by default. Codex always declares the hosted `web_search` tool, and the passthrough relays it on the assumption the destination executes it. A gateway that does not (Ollama Cloud GLM/DeepSeek) answers with a `function_call` named `web_search` that nothing runs, and the undeclared-tool guard ends the turn. With `enabled: true` OpenCodex intercepts that call, runs the search itself, feeds the result back to the same upstream, and shows Codex a hosted `web_search_call` cell. Never armed for `authMode: "forward"` (ChatGPT already searches) or for a provider that executes hosted search upstream. Only the `ollama` backend has an executor; the other ids in the union are accepted and stay inert. The `ollama` backend reuses this provider's own API key on `POST <origin>/api/web_search`, so the origin must be `https://ollama.com` unless the operator names `endpoint` explicitly. Streaming turns only; a turn that mixes `web_search` with another client tool call fails closed rather than dropping the client's call. Defaults: `maxSearches: 3` (1..10), `timeoutMs: 60000` (1000..600000). | |

Align the webSearchBridge row with the shipped schema and planner.
The backend field accepts ollama, anthropic, xai, gemini, and exa, but only ollama has a shipped executor. List the full union in the type column.
The planner does not check xaiResponsesXSearch or the provider destination. The built-in xai provider permits key-auth override, and an explicit endpoint can arm the bridge for that provider. Remove “Never armed ... for a provider that executes hosted search,” or add the exclusion to planPassthroughWebSearchBridge in src/web-search/passthrough-bridge.ts.

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift
Route bridge continuation sends through bounded upstream recovery
At src/server/responses/core.ts:5792-5804, continuation sends call fetchWithHeaderTimeout directly. The first leg uses fetchWithTransientRetry at src/server/responses/core.ts:5047-5063, which retries transient 5xx responses and connection resets for the replayable string body. bridgeStreamBlocks converts a continuation exception or non-success response into response.failed at src/web-search/passthrough-bridge.ts:707-722. Therefore, a transient post-search failure can terminate an otherwise recoverable bridged turn.
Wrap each continuation send in the same bounded retry policy. Pass applyUpstreamRecoveryInit(...) the recovery kind for each attempt so connection-reset retries also avoid stale transport connections. Keep continuationBody as the request body; this change does not require credential refresh or request-body replacement.

At src/server/responses/core.ts:5799, oauthDispatch(request) can rebuild dispatchInit from the original parsed request when providerApiKeySelectionIsCurrent returns false. This replaces the continuation body and can remove its function_call_output, causing repeated web_search calls until the bridge budget is exhausted.
At src/server/responses/core.ts:5805, createOllamaBridgeExecutor captures route.provider.apiKey once. A later key rotation can therefore make every search request use the retired key and return ollama web-search HTTP 401.
Do not pass oauthDispatch(request) to continuation sends. If key rotation must apply during the bridge, resolve the current provider key and executor at send time without rebuilding the continuation body. Add a regression test that rotates the key between legs and asserts both the preserved function_call_output and the current search credential.

Pin the accepted ends of the bounds, not only the rejected ones.
This test proves that maxSearches: 99 and timeoutMs: 1 fall back to 3 and 60_000. It does not prove that a value inside the documented range survives. The planner (src/web-search/passthrough-bridge.ts lines 141-149) gates on >= 1 && <= 10 and >= 1_000 && <= 600_000. If someone tightens either comparison to a strict inequality, or drops a clause, every assertion in this file still passes while an operator's configured maxSearches: 10 is silently clamped back to the default of 3. The operator gets fewer searches than configured, with no error and no test failure.
Add the accepted edges so both sides of each bound are pinned.

Assert that bridge sequence numbers exist and increase strictly
BridgeStreamState.render stamps each emitted payload with sequence_number: this.sequence++. The upstream fixture frames omit this field, so the bridge must add it. The current sort assertion does not require that field. If every value is undefined, the numeric comparator returns NaN, the order is unchanged, and the test passes. The repository test runner includes this test under ./tests/, so this is an enforced regression-test gap.

Summary
Codex always POSTs
/v1/responseswith the hosted{type:"web_search"}tool. On the KEY-auth Responses passthrough OpenCodex reads that declaration as "the destination executes search itself" and relays it unchanged, which is true for the ChatGPT backend and for xAI. It is false for an OpenAI-shaped key gateway that does not run the hosted tool: Ollama Cloud GLM answers with a plain{type:"function_call", name:"web_search"}, nothing on either side executes it, and the undeclared-tool guard ends the turn withundeclared_tool_callbecause a hosted declaration never authorizes a client function name.This adds an opt-in, default-OFF bridge for exactly that case:
providers.<name>.webSearchBridge = { enabled: true, backend: "ollama" }.When it arms, the passthrough SSE body is wrapped before the relay rewrites. The bridge intercepts the
web_searchcall out of the upstream stream, runs the configured search backend itself, appends the call plus itsfunction_call_outputto the same raw outbound body, POSTs the next leg to the same upstream, and emits the hostedweb_search_callframes Codex already renders (the shapesrc/bridge.tsproduces for the sidecar). The stream it hands back is ordinary Responses SSE, so every existing rewrite — including the undeclared-tool guard, the payload repairs, terminal-outcome recording, and the continuation cache — still applies to the client-facing stream.Before/after with the bridge enabled on an Ollama Cloud provider, for a turn where GLM asks to search:
response.failed/undeclared_tool_callweb_search_callin_progress + completed, then the answerfunction_call+function_call_outputcarrying the search resultArming is fail-closed on every axis. It requires
parsed._webSearch, the passthrough adapter,authMode: "key",enabled: true, atool_choicethat still allows search, and a streaming turn. It never arms forauthMode: "forward"(ChatGPT already searches with the caller's own credential) or for a stored OAuth credential, and it never pre-empts a provider that executes hosted search upstream. This is a new planner,planPassthroughWebSearchBridge, rather than a relaxation ofisPassthroughinplanWebSearch: the sidecar rewrites normalized messages, while this path has to preserve the raw Responses conversation.web_searchis not added to the guard's allowed names. The call is removed from the stream because the proxy answers it; an unrelated undeclared tool still fails closed, and that is pinned by a sibling fixture.Backend and destination policy:
ollamahas a shipped executor.openai,anthropic,xai,gemini, andexaare accepted by the config union and stay inert, the same explicit-only contractwebSearchSidecaruses for backends whose executor has not landed. Nothing auto-selects a paid Luna or Exa search.ollamabackend derivesPOST <origin>/api/web_searchonly when the provider'sbaseUrlorigin ishttps://ollama.com. Any other origin requires an explicitendpoint, because the bridge reuses the provider's own route key on that URL and an operator naming the endpoint is the authorization for it. The executor sendsredirect: "manual"so a redirect cannot carry the key elsewhere, and scrubs the literal key out of every error string.Deliberate boundaries of this first slice, kept narrow on purpose:
web_search_bridge_mixed_toolserror instead of dropping the client's call. Answering both needs the raw mixed-tool continuation contract the 2.47 track deferred (devlog/_plan/260907_track2_protocol/040_hosted_search_disposition.md), and this PR does not open that.sequence_numberandoutput_index) because events are both dropped and injected; a plain relay cannot preserve upstream numbering through that. The terminalresponse.outputis rebuilt from the items the client actually received so the snapshot matches the streamed turn.With the flag off the change is one planner call that returns

The cell now opens at intercept time and keeps thatoutput_index; a reserved snapshot slot keeps the terminalresponse.outputin the same order the client saw.checkOutboundBodySizeto every continuation body and the bridged turn fails rather than sending an unbounded one.Suppression is also keyed on

autotee path a client disconnect cancels the client branch while the inspection branch still drains, andupstream.abort()runs at the end of that bounded drain. During that window the bridge can complete one search and one continuation before its abort check fires. It is bounded bymaxSearchesand the existing drain bounds; closing it means changing where the relay tees, which is outside this PR.Checklist
