fix(zcode): attach over the proxy Responses route instead of Chat Completions - #4302
Conversation
…pletions
ZCode dispatches kind "openai" to {baseURL}/responses, which is the only surface the proxy speaks natively; the Chat inbound translated each turn into a Responses body and back. Closes #4295.

리뷰 · 우선순위 73 / 80설명 이 PR은 ZCode가 OpenCodex 프록시에 붙는 길을 Chat Completions에서 Responses로 바꾸는 수정입니다. 지금 ZCode 쪽 권위는 번들에서 뽑은 디스패치입니다. kind enum은 anthropic / openai / openai-compatible 세 값이고, openai는 /responses, openai-compatible은 /chat/completions로 갑니다. baseURL 정규화도 openai kind에서는 /responses 접미사만 떼므로, 지금처럼 코드 변경은 작습니다. 타입 리터럴과 빌더 값의 kind, 그리고 그걸 설명하는 주석 세 블록입니다. baseURL 조립식( 같은 커밋 묶음에

For an existing managed ZCode installation, changing this builder only makes readIntegrationState report stale; it does not rewrite the file automatically. The default fan-out in src/integrations/catalog-refresh.ts:13 excludes ZCode, as does the explicit ocx sync list in src/cli/dispatch.ts:448-455, and startup refreshes only Raycast. Consequently, an untouched ~/.zcode/v2/config.json retains kind: "openai-compatible" and continues using Chat Completions until the user manually reapplies the integration, contrary to the intended automatic migration. Add a ZCode refresh/migration path and cover it using an old-kind ownership record.

structure/INDEX.md:101 maps all of src/clients/ to structure/clients/integrations.md, but this change alters the generated ZCode provider contract without updating that owned document. Record the Responses protocol and migration behavior there in the same change rather than leaving the contract only in the devlog.

Switching the generated on-disk kind changes ZCode's request protocol and requires existing users to get their managed block refreshed, yet no docs-site/ page or release note was updated. Document that ZCode now targets /v1/responses and explain how an existing installation receives or manually applies the migration.

Correct the optional modality handling.
The schema allows modalities and modalities.input to be omitted, but the documented projection directly evaluates y.modalities.input.includes("image"). Such a configuration can throw during model loading. Guard both fields in the implementation or document the required invariant and add a regression test for the omitted-field case.

Add a focused regression test for the ZCode kind migration.
The existing tests cover the new export and hand-edited kind conflicts, but not an untouched installation created with kind: "openai-compatible". Extend tests/clients/integrations-writer.test.ts near the existing ZCode conflict test (lines 552-573). Seed the old JSON and ownership record with the existing store.putRecord harness, assert readIntegrationState() returns stale, apply the integration, and assert the rewritten provider uses kind: "openai".

Summary
ZCode attached to the proxy over Chat Completions, which is not a surface the proxy speaks natively.
src/server/chat-completions.tstranslates an inbound Chat body into a Responses body, replays it throughhandleResponses, then translates the stream back — two translations per turn, with tool-call deltas and reasoning blocks reshaped on the way through.ZCode 3.11.2 dispatches each provider kind to a fixed path. Extracted from the shipped bundle:
So exporting
kind: "openai"sends ZCode to{baseURL}/responses.baseURLis unchanged: ZCode'snormalizeModelProviderBaseUrlForKindstrips only the/responsessuffix for that kind, so the serialized/v1root survives and the turn lands onPOST /v1/responses— the routesrc/server/index.tsregisters directly againsthandleResponses. No translation at all.The reasoning block is unaffected:
enabled/variants/defaultVariantis the same on-disk schema for every kind. Only the wire field differs, andopenaiemitsreasoning.effort, which/v1/responsesreads natively rather than thereasoning_effortthe old comment described.An installation that has not hand-edited its config follows automatically.
kindis not a refreshable path, but an untouched file still matches its recorded fingerprint, so the record goesstalerather thanconflictand a refresh rewrites the fragment. A user who setskindback by hand keeps owning that edit — the new test pins that.Closes #4295.
