The new tests also cannot reliably exercise the transformation, and a minor error-response metadata issue remains.

Propagate and emit the Code Mode input.
currentToolCall is initialized at Line 1105 without codeModeExecCommand. Therefore, the condition at Line 643 is always false. The bridge uses freeformInput(...) at Lines 667-688 and sends the raw JSON arguments instead of the generated tools.exec_command(...) script.
Copy mapped?.codeModeExecCommand into currentToolCall. Use the resolved non-null customInput for both response.custom_tool_call_input.done and the completed custom_tool_call item.
Proposed fix
- currentToolCall = { itemId, outputIndex, callId: event.id, name: realName, args: "", argsBytes: 0, namespace: ns, freeform, toolSearch, providerMetadata: event.providerMetadata };
+ currentToolCall = {
+ itemId, outputIndex, callId: event.id, name: realName, args: "", argsBytes: 0,
+ namespace: ns, freeform,
+ codeModeExecCommand: mapped?.codeModeExecCommand === true,
+ toolSearch, providerMetadata: event.providerMetadata,
+ };
- const customInput = currentToolCall.codeModeExecCommand
+ const customInput = currentToolCall.codeModeExecCommand
? currentToolCall.codeModeExecCommandInput ?? codeModeExecCommandInput(currentToolCall.args)
- : freeformInput(currentToolCall.args);

Return the supported translator-budget metadata. formatErrorResponse accepts only code and retryAfter, so requestId is not serialized. Add code: "translation_buffer_limit" at src/server/responses/core.ts:2946, matching the other translator-budget branches. Extend formatErrorResponse and its response schema if clients need requestId.

Use the declared AdapterEvent fields and decode SSE bytes.
At tests/sensenova-code-mode-exec-alias.test.ts:8-11, bridgeToResponsesSSE reads id, arguments, and stopReason, but the test provides callId, delta, and finishReason. The delta branch passes undefined event.arguments to appendString, which calls Buffer.byteLength, so the tool input cannot be assembled. Use id, arguments, and stopReason.
At tests/sensenova-code-mode-exec-alias.test.ts:24-30, the bridge returns ReadableStream<Uint8Array> and enqueues TextEncoder bytes. Decode each chunk with TextDecoder before splitting SSE lines.

…rge round Compile-gates all 12 PRs in isolated worktrees, which the draft-PR CI does not do, and assigns each to a disposition lane. Two PRs are not what their status says: - lidge-jun#2694 is review-ready with green checks and does not compile (5 tsc errors, including a call to a function defined nowhere). - lidge-jun#2693 is a test-only diff whose test fails on its own branch; the implementation was never written. lidge-jun#2639 is a real fix carrying a real regression: its created_at backfill breaks the byte-exact passthrough assertion in tests/server-combo-failover-e2e.test.ts:1323.
Independent audit found three overconfident claims: the compile gate ran on stale PR heads (4-294 commits behind dev), lidge-jun#2684 and lidge-jun#2690 do conflict on src/adapters/openai-chat.ts, and "lidge-jun#2663 CI green" cites the same five non-compiling checks that let lidge-jun#2694 ship five tsc errors.
Providers that advertise Code Mode can emit a bare helper call — exec_command, apply_patch — instead of wrapping it in the code-mode exec envelope the client declared. The bridge then relays a call the client never declared, and the turn fails on an undeclared-tool guard or an invalid custom_tool_call. Squashed from #2663 by Eleven-is-cool, whose implementation is taken whole: - src/responses/code-mode-helper-compat.ts synthesizes the exec wrapper for a bare helper call - custom-tool-compat and responses-custom-tool-repair carry the repair through the non-stream and repair paths - the undeclared-tool guard keeps its fail-closed behavior for anything that is not a recognized helper Landed as one commit rather than a 12-file merge so the history has a single revert point for a change on the shared request path. Tests: legacy-shell-compat, responses-custom-tool-repair, responses-undeclared-tool-guard, bridge, bridge-legacy-shell-normalization and responses-stream-tool-events — 176 pass / 0 fail. tsc clean. Note for the record: this PR's five green checks (CodeRabbit, enforce-target, hygiene, label, resolve-pr) compile and test nothing — the same five that let #2694 ship five tsc errors. The evidence here is the merged-tree typecheck and the suites above, not the badges. Closes #2663

Closing as already fixed — Your diagnosis was right: a provider can emit a bare That is the same wrapper your Two things worth passing on, since they cost this PR its chance to land first. It does not compile. On
The gate keys on a provider id that does not exist. If SenseNova still misbehaves in a way the general bridge misses, a follow-up with a test that goes through the real request path would be very welcome. Thanks for the report — the underlying observation was correct and it is fixed. |

Problem
When Codex operates in Code Mode, the client orchestrates execution via the top-level
exectool (evaluating a JavaScript module that invokesawait tools.exec_command(...)).However, some models (such as SenseNova / SenseChat) frequently emit a bare
exec_commandfunction call with JSON arguments (e.g.{"cmd": "..."}) rather than emitting the JavaScript isolate wrapperexec({ input: "..." }). This mismatch leads to client-side tool resolution failures, 499 disconnects, or unexpected syntax rejections in the code-mode loop.Solution
src/bridge.ts, detect when a model emits a directexec_commandfunction call while in Code Mode, and synthesize the canonical JavaScript execution wrapper:response.custom_tool_call_input.done/custom_tool_callframe on the Responses SSE wire so Codex can evaluate it cleanly without client-side modifications.Changes
