Inline comments:
In `@docs-site/src/content/docs/ja/reference/adapters.md`:
- Around line 49-51: Update the adapter descriptions to distinguish canonical
OpenAI forwarding from noncanonical routed gateways: document safe header
forwarding for canonical requests, omit caller authorization relay for
noncanonical providers, and describe rewriting client-executable tool_search
into public function tools with JSON/SSE restoration to tool_search_call. Apply
this in docs-site/src/content/docs/ja/reference/adapters.md lines 49-51 and
docs-site/src/content/docs/ko/reference/adapters.md lines 56-58, keeping both
translations aligned with the English behavior.
In `@src/adapters/base.ts`:
- Around line 55-56: Make tool_search restoration collision-safe in the
tool-search compatibility flow: ensure private tool_search and ordinary function
declarations receive distinct upstream identities or retain enough identity to
distinguish them. Update the function_call restoration logic around
convertedRoutedToolSearchNames so only the private tool-search call becomes
tool_search_call, while ordinary tool_search calls remain function calls. Add a
regression test covering both declarations.
In `@src/responses/parser.ts`:
- Around line 216-221: Apply normalizeParameters to the result of
toolSearchParameters(t) in the tool_search branch of buildTools before assigning
it to parameters, matching the existing pushFn handling and ensuring declared
tool-search schemas always include type: "object".
In `@src/responses/tool-search-compat.ts`:
- Around line 83-94: The request transformation around
rewriteRoutedToolSearchForUpstream must also rewrite deferred tool-search
history items, converting tool_search_call/tool_search_output entries to
supported function_call/function_call_output entries with tsc_ to fc_ ID
mapping, JSON-string arguments, and preserved call_id pairing. Ensure the
converted history is used in the serialized outbound body and add a second-turn
test that verifies the forwarded payload.
- Around line 28-47: Update rewriteToolList and the request normalization flow
to handle collisions between lowered tool_search declarations and ordinary
functions named tool_search: reject ambiguous requests or assign the lowered
tool a distinct wire alias. Apply the same validation or aliasing to both
body.tools and additional_tools.tools, and add a regression test covering both
declarations plus an ordinary tool_search call.
In `@src/server/responses-tool-search-repair.ts`:
- Around line 142-148: Restrict the call to restoreRoutedToolSearchCalls in the
remaining-payload path so it runs only for response.completed, response.failed,
or response.incomplete events; return the original block unchanged for other
event types, especially *.delta frames. Preserve the existing releaseAll
handling and replacement behavior for terminal snapshots.
- Around line 46-54: Update retainPending, takePending, and releaseAll to
enforce explicit pending-frame and retained-byte caps while keeping accounting
consistent; when the collector is full or budget.chargeRetained rejects, stop
retaining and mark the rewrite for pass-through instead of propagating the
budget error. Ensure relaySseWithBlockRewrite and relaySseEagerBounded continue
safely without retaining unbounded unmatched frames.
In `@tests/responses-tool-search-repair.test.ts`:
- Around line 112-168: The test coverage should exercise the ordinary-item
replay branch and terminal buffer release in
createRoutedToolSearchRestoreBlockRewrite: add a focused test with a buffered
argument frame lacking item_id, verify replay injects the resolved id and
preserves the ordinary item, then buffer an unmatched frame and verify
response.completed releases the budget. Also assert the routed added result has
exactly one frame, and strengthen the lowering test to verify tool_choice.mode
remains required and the ordinary tools entry is preserved.

Add a lowered tool_search declaration and add wireName to names for history-only requests. Add a regression test with ordinary tools and tool-search history.

Overflow passthrough is not atomic while a routed item is open.
Both fallback branches (Line 64-75 and Line 79-91) set passthrough = true and call routedItemIds.clear(). From that point Line 133 returns every block unchanged.
Overflow is reachable while a routed item is already open on a different output_index:
response.output_item.addedforoutput_index: 0names a routed tool. Line 176 emits it rewritten totool_search_callwith idtsc_search, androutedItemIdsholdsfc_search.- Argument frames for an unrelated
output_index: 1arrive before their ownoutput_item.addedand accumulate. The 256-frame or 1 MiB cap trips, orchargeRetainedrejects. passthroughis set androutedItemIdsis cleared.- The remaining
response.function_call_arguments.delta/.doneframes forfc_search, and itsresponse.output_item.done, now reach the client verbatim.
The client already received tool_search_call / tsc_search for that item, so it then receives function-call argument frames and a function_call done item for an fc_search id it never saw. Codex cannot reconcile that lifecycle. Suppression for already-classified routed items must survive the fallback, since dropping those frames costs nothing and requires no buffering.
🛡️ Proposed fix: keep routed suppression across the fallback
let pendingArguments: PendingArgumentBlock[] = [];
let pendingArgumentBytes = 0;
let passthrough = false;
let disposed = false;
+
+ // Entering passthrough must not resurrect the public lifecycle of an item whose
+ // `output_item.added` was already rewritten to `tool_search_call`.
+ const enterPassthrough = (): void => {
+ passthrough = true;
+ ordinaryItemIds.clear();
+ };Then replace both passthrough = true; routedItemIds.clear(); ordinaryItemIds.clear(); sequences with enterPassthrough();, and gate the early return so routed items stay suppressed:
const rewrite: SseBlockRewrite = (block: string): readonly string[] => {
if (disposed) return [block];
- if (passthrough) return [block];
+ if (passthrough && routedItemIds.size === 0) return [block];With routedItemIds retained, Line 182-185 keeps dropping the routed argument frames and Line 150-177 keeps restoring the routed output_item.done, while every unknown frame is relayed immediately instead of buffered.
As per path instructions for tests/**: "A behavior change in src/ should come with a focused regression test near the existing tests for that subsystem." The existing overflow test at tests/responses-tool-search-repair.test.ts Line 302-323 overflows before any item is classified, so it does not cover this interleaving. Add a case that opens a routed item first, then overflows on a second output_index.

Thanks for this, @Ingwannu — closing as superseded by #2145, which carries your implementation and your full test suite. The rewrite/restore design, the collision aliasing, the bounded pending buffer, and the canonical-forward gate are all yours. Two corrections were added for findings that were still open here:
Both are pinned by new tests that I verified fail against your two modules and pass with the corrections, so they are real guards rather than restatements. This is your third PR landing in this pass — #2056 is credited in #2141 and your K12 work is in there too. Your work is credited in #2145's description. |
…hrough
Passthrough forwarded Codex's private {type:"tool_search"} unchanged to
third-party /v1/responses gateways, which only understand public function tools.
The model never saw a callable tool_search and emitted zero tool_search_call
items, so deferred tool discovery silently did nothing on every routed provider.
Lower the private tool to a public function on noncanonical forward targets,
rewrite tool_choice and replayed history to match, then restore the private
tool_search_call lifecycle on the way back so Codex sees what it can execute.
Canonical ChatGPT forward is untouched.
Carries @Ingwannu's lidge-jun#2040 implementation and tests, with two corrections for
findings that were still open on it:
History-only replay. A turn may replay tool_search history without re-declaring
the tool. The history was lowered either way, but restoration was armed only
when a declaration was present, so the client got back a public function_call
for what it had issued as a private search call.
SSE overflow was not atomic. Both overflow branches cleared routedItemIds along
with the pending buffer, so an item already restored to tool_search_call started
emitting function_call_arguments frames again and the client saw a mixed
private/public lifecycle for one call. Overflow now stops buffering unknown
frames without forgetting what was already classified.

This change is scoped to the Bun/TypeScript Responses passthrough. The current remote exposes
dev,main, andpreviewbut notdev2-go, so there is no reachable Go integration branch to port in this PR. Re-evaluate the corresponding Go boundary if that branch is published before merge.Checklist
