Summary

  • limit Muse Spark web-search sanitization to the exact effective OpenCode Zen and Zen Go Responses destinations
  • preserve search_content_types and indexed_web_access for direct Meta and unrelated Responses providers
  • cover full baseUrl and split baseUrl + responsesPath configurations, including nested additional_tools

Problem

stripMuseSparkUnsupportedWebSearchFields was keyed only by model id and ran for every noncanonical Responses provider. The direct meta-model and meta-muse providers expose the same Muse Spark Contributor ids, so OpenCodex removed fields there even though the rejection evidence applies only to the OpenCode gateways.

This is a focused follow-up to the out-of-diff review finding on #3394; it does not change that merged Grok fix.

Fix

The sanitizer now receives the effective request URL already constructed by buildRequest and applies the existing removal only for:

  • https://opencode.ai/zen/v1/responses
  • https://opencode.ai/zen/go/v1/responses

This covers both canonical provider base URLs and root URLs paired with responsesPath. Malformed, credentialed, query-bearing, hash-bearing, and unrelated destinations keep their original request shape.

Validation

  • bun test tests/muse-spark-web-search-compat.test.ts — 11 passed
  • bun run typecheck
  • bun run privacy:scan
  • bun run test — 17,611 passed, 14 skipped, 0 failed

📝 Walkthrough

Walkthrough

The request adapter now applies Muse Spark web-search sanitization only for supported Zen and OpenCode Go response URLs. Tests cover direct and split-path configurations, OpenCode Go, and direct Meta preservation.

Changes

Muse Spark compatibility

Layer / File(s) Summary
Destination-gated sanitization
src/adapters/openai-responses.ts:2119-2153, src/adapters/openai-responses.ts:2432
The adapter restricts Muse Spark field removal to two normalized OpenCode response destinations. It rejects URLs with credentials, queries, hashes, or invalid syntax, and passes the effective request URL to the sanitizer.
Provider-specific compatibility tests
tests/muse-spark-web-search-compat.test.ts:10-68, tests/muse-spark-web-search-compat.test.ts:160-193
The tests use parameterized provider configurations. They verify sanitization for OpenCode Go and split baseUrl/responsesPath configurations, and verify field preservation for direct Meta at top-level and nested locations.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to bf422

Muse Spark web-search fields are now removed only for the supported OpenCode Zen endpoints while direct Meta and unrelated providers retain them. The scoped behavior and compatibility coverage leave no identified merge-blocking risk.

설명

지금 dev HEAD(df53a9980)의 src/adapters/openai-responses.ts에는 Muse Spark Contributor 모델용 stripMuseSparkUnsupportedWebSearchFields가 있습니다. 이 함수는 muse-spark-1.3-contributor / muse-spark-1.2-contributor 모델 id만 보고, Codex가 넣는 web_search 필드 중 OpenCode 게이트웨이가 거절하는 search_content_typesindexed_web_access를 지웁니다. 문제는 모델 id가 같은 길이라도 가는 곳이 다르면 거절 증거가 다르다는 점입니다. 레지스트리의 meta-modelmeta-musebaseUrl: https://api.meta.ai/v1로 같은 Contributor id를 쓰는데, 지금은 noncanonical Responses면 전부 같은 strip이 돌아갑니다. 직접 Meta로 가는 요청까지 OpenCode Zen/Go용 호환 패치가 먹으면, Meta가 받아 주는 필드를 우리가 먼저 깎아버립니다.

이 PR은 strip 조건을 모델 id + 목적지 URL로 좁힙니다. 허용 목적지는 https://opencode.ai/zen/v1https://opencode.ai/zen/go/v1 두 개뿐입니다. provider.baseUrlURL로 파싱해 origin + pathname(끝 슬래시 제거)을 만들고, username·password·search·hash가 있으면 strip을 건너뜁니다. 호출부도 stripMuseSparkUnsupportedWebSearchFields(outBody, parsed.modelId, provider)로 바꿉니다. 테스트는 기존 Zen 경로를 유지하면서 Zen Go strip과 Meta(api.meta.ai/v1) 보존을 tools와 nested additional_tools 양쪽에서 확인합니다. 범위는 #3394(OpenCode Go Grok Responses) 리뷰에서 나온 out-of-diff 후속이고, 그 머지 본문은 건드리지 않습니다. 현재 dev 방향(OpenCode Go/Muse Spark Responses 정리)과 정확히 맞습니다.

src/adapters/openai-responses.ts / MUSE_SPARK_WEB_SEARCH_STRICT_DESTINATIONS - Zen과 Zen Go만 allowlist에 넣습니다. 같은 opencode.ai/zen/v1를 쓰는 opencode-zen / opencode-free도 strip 대상이 됩니다. 거절 증거가 그 게이트웨이에 있으므로 맞습니다.

src/adapters/openai-responses.ts / destination 정규화 - username·password·query·hash가 있으면 body를 그대로 둡니다. 보수적이라 안전하지만, 운영자가 Zen URL에 쿼리를 붙인 커스텀 baseUrl이면 strip이 안 돌아가 다시 400이 날 수 있습니다. 의도된 fail-open인지 한 줄로 적어 두면 좋습니다.

tests/muse-spark-web-search-compat.test.ts - Meta 보존 케이스가 top-level과 nested를 같이 봅니다. 회귀를 막는 핵심입니다. Zen Go도 같은 가드를 쓰는지도 확인합니다.

PR 상태 - draft이고 readiness checklist가 아직 비어 있습니다. 코드 방향은 이미 분명하지만, 작성자 체크리스트·전체 CI 초록을 기다린 뒤 merge하는 편이 맞습니다.

메인테이너의 판단이 필요한 지점

  • command-code 등 다른 reseller도 같은 Muse web_search 필드를 거절하는지. 거절 증거가 있으면 allowlist에 넣을지, 이번엔 OpenCode만 두고 후속으로 둘지.
  • Zen URL에 query/credentials가 붙은 커스텀 baseUrl에서 strip을 건너뛰는 동작을 문서/주석으로 고정할지.
  • draft checklist를 채운 뒤에만 merge할지, 아니면 CI만 초록이면 ready로 올려 merge할지.

너의 추천

방향은 맞고 회귀 면적도 작습니다. draft가 풀리고 CI가 초록이면 merge하세요. merge 전에 Meta 경로 스모크(Contributor + web_searchsearch_content_types/indexed_web_access 유지)와 Zen/Zen Go 400 재현→strip 확인만 하면 충분합니다. types/config split과 무관하고, preview 배포도 필요 없습니다.

Approving. This is the right tightening on top of #3405.

Keying the sanitizer on the model id alone meant any provider serving a same-named model would get Codex web_search fields stripped from its request — a rewrite applied on the strength of a name rather than a destination. Matching the exact effective response URL fixes that, and rejecting URLs carrying credentials, a query, or a fragment is the correct instinct: those are precisely the shapes where "it looks like the right host" stops being a safe inference.

Normalizing with url.origin.toLowerCase() plus a trailing-slash-trimmed pathname, against an explicit two-entry set, keeps it exact without being brittle about case or a stray slash. Covering both the baseUrl and responsesPath provider shapes in the tests is what makes the set trustworthy — those two produce the same effective URL by different routes, and a check that only handled one would pass while leaving a live path unscoped.

bun test tests/muse-spark-web-search-compat.test.ts is 11 pass / 0 fail and bun x tsc --noEmit is clean on this head. Thanks for coming back to narrow it.
