fix(responses): convert unpaired tool results without leaking invalid envelopes#4059Platinum-Scripts wants to merge 1 commit into
Conversation
… envelopes Translating adapters were 400ing Codex desktop sub-agent seeds because a function_call_output with no call_id survived parseRequest as an unpaired toolResult. Convert ordinary missing/empty call_id outputs (including tool_search_output) into user context before parse, keep leftover unpaired items fail-closed, and leave complete/invalid external-task envelopes for the parser. Fixes lidge-jun#3807.

Priority: ➖ Normal Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to Call-id-less custom tool outputs now proceed as user context, but the test does not confirm that the original output content reaches the upstream request. This creates a bounded risk of silently losing tool-result context. Sequence Diagram(s)sequenceDiagram

리뷰 · 우선순위 52 / 80설명 이 PR은 translating 지금 중요한 점은 검증 주장은 타깃 테스트 58 pass, 이웃 responses 스위트 388 pass, typecheck 통과입니다. CI는 이 글을 쓰는 시점엔 enforce-target/hygiene/label/resolve-pr는 통과했고 CodeRabbit은 아직 pending입니다. 파일은 라인 라인 경로 경로 경로 본문 요약 vs 실제 효과 - “Codex desktop sub-agent seeds(#3807)를 400 대신 고친다”는 문장은, 완전 envelope + 필드 생략 시드에는 해당이 거의 없고, null/empty 경로 passthrough - 기존 호출은 옵션 없이 그대로라 envelope도 raw에서 user로 바꿉니다. 본문이 말한 “passthrough는 parsed messages를 안 읽으니 계속 변환”과 맞습니다. 회귀 위험은 translating 쪽 정책 변화에 더 있습니다. 메인테이너의 판단이 필요한 지점

Assert the converted custom-tool output content.
This test accepts a successful upstream request without proving that "x" was retained in user context. A regression that drops the custom_tool_call_output payload would still pass. Assert the forwarded body contains "x" and does not contain "undefined".
Proposed test update
expect(res.status).toBe(200);
expect(bodies).toHaveLength(1);
+ expect(bodies[0]).toContain("x");
+ expect(bodies[0]).not.toContain("undefined");As per coding guidelines: “A behavior change in src/ should come with a focused regression test near the existing tests for that subsystem.”

Summary
call_idtool outputs on the translating/v1/responsespath beforeparseRequest, instead of 400ing Codex desktop sub-agent seeds ([Bug] 2.43.0 unpaired-tool-result guard rejects Codex desktop sub-agent seed shape: every routed-model delegated thread dies instantly with 400 "tool result requires a non-empty string call_id" #3807).function_call_output,custom_tool_call_output, andtool_search_outputitems with no usablecall_idinto user context so routed adapters never seetoolCallId: undefined.id/name/namespace) alone at parse time so complete envelopes still admit as user text and invalid envelope fixtures still 400 before upstream work.toolResults fail-closed after parse.
