Summary

  • Documents the __omit__ wire sentinel (added in fix(reasoning): support per-effort field omission sentinel (__omit__) #2361) across src/types/provider.ts and all localized provider configuration references (docs-site/src/content/docs/**/reference/configuration/providers.md).
  • Clarifies that mapping a Codex reasoning label to "__omit__" in reasoningEffortMap or modelReasoningEffortMap completely drops the reasoning_effort field from upstream requests (e.g. for Ollama models whose chat templates require omitting the field to engage deep thinking mode).

Verification

  • git diff --check clean (no trailing whitespace).
  • Verified consistent table formatting and translation accuracy across English, Simplified Chinese, Traditional Chinese, Japanese, Korean, French, Russian, and Turkish docs.

Checklist

  • Scope stays focused and avoids unrelated cleanup.
  • Docs or release notes were updated when needed.
  • Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults.

Review readiness checklist

This PR stays in draft until every box below is ticked. Tick all four boxes once the requirements are met:

  • All CI tests are green on my local testing.
  • I pushed my PR to the latest dev commit.
  • I resolved all correct Codex and CodeRabbit findings.

Summary by CodeRabbit

  • Documentation
    • Clarified that mapping a reasoning label to "__omit__" completely removes the reasoning field from upstream requests.
    • Documented this behavior for both provider-wide and model-specific reasoning settings.
    • Added an Ollama example and noted that the upstream model’s default can apply when reasoning is omitted.
    • Updated the guidance across supported language versions.

Review Change Stack

📝 Walkthrough

Walkthrough

The change documents the "__omit__" sentinel for provider-wide and model-specific reasoning-effort mappings. The TypeScript configuration comments and localized provider documentation now state that the upstream reasoning field is omitted.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: ⚪ Minimal · up to c3493

The PR documents the __omit__ reasoning-effort behavior across provider configuration references. One French example should clarify that chat templates, rather than models, require the field to be omitted; this is a minor documentation correction and does not block the underlying change.

Restore the meaning of “templates” in the French example.

Line 103 uses modèles Ollama dont les modèles nécessitent, which reads as “Ollama models whose models require” and loses the chat template subject. Replace it with modèles Ollama dont les templates de chat nécessitent or equivalent French wording.

As per path instructions: user-facing documentation must stay consistent with the English source and actual behavior.

The documented __omit__ behavior matches src/reasoning-effort.ts and the existing adapter regressions, so the direction is valuable. I am requesting two small documentation fixes before approval:

  1. docs-site/src/content/docs/fr/reference/configuration/providers.md currently says les modèles Ollama dont les modèles nécessitent..., which changes the meaning and repeats “models.” The upstream constraint belongs to the chat template, not to a second model. Please use wording such as les modèles Ollama dont le gabarit de conversation exige l'omission de reasoning_effort pour activer le mode de raisonnement approfondi.
  2. Every newly added localized table row begins with an extra leading space ( | ...) while the surrounding table rows start at column 1. Remove that space in all eight provider-reference files so the patch preserves the existing table source format and does not depend on parser tolerance.

After those exact documentation corrections, rerun the docs-site build on the updated head. No runtime change or additional test expansion is needed for this PR.

리뷰 · 우선순위 32 / 80

설명: 이 PR 은 생각 세기를 위로 보낼 때 칸을 빼라는 표시 __omit__ 을 설정 문서에 적는다. 지금 CURRENT dev HEAD 는 4f41a8e93 이다. 이번 시간에 origin/dev 는 그대로다. 새 머지는 없다. 착지는 여전히 2396 사용량 CLI 오늘 비용이다. package.json 은 2.27.0 이다. src/config.ts 는 3975줄이다. src/runtime 폴더는 지금 HEAD 에 없다. 이 PR 의 베이스는 지금 HEAD 와 같다. 위에 올라간 커밋은 하나다.

동작은 이미 HEAD 에 있다. 2361 이 넣었다. src/reasoning-effort.ts 21줄이 그 표시이고, 185줄과 196줄이 그 값이면 칸을 뺀다. tests/reasoning-effort.test.ts 977줄이 올라마 큐웬 보기와 함께 이미 잠근다. 그런데 영어 설정 문서 104줄과 105줄은 별칭만 적는다. 표시 말이 없다. 한국 문서 91줄도 같다. 그래서 쓰는 사람은 칸을 어떻게 빼는지 문서에서 못 찾는다. 2356 이 그 구멍을 말했고, 2361 이 코드를 넣었지만 문서는 안 고쳤다.

이 PR 은 여덟 나라 문서와 src/types/provider.ts 주석에 그 말을 넣는다. 제품 코드는 안 바뀐다. 그런데 고친 표 줄 앞에 빈칸이 있다. 표 줄은 | 로 시작해야 한다. 빈칸이 붙으면 그 줄이 표에서 빠진다. 새 문장이 칸에 안 들어간다. 작성자는 표 모양이 맞다고 적었는데, 여덟 나라 모두 같은 빈칸이다. 주석이 말하는 위 모델 기본값을 쓴다 와 문서가 말하는 칸을 아예 뺀다 는 같은 동작이다. mapReasoningEffort 가 값을 안 돌려주기 때문이다.

위생은 통과다. 타깃, 라벨, CodeRabbit 도 통과다. 체크리스트 네 칸이 채워져 있다. 게이트가 review-ready 를 붙였다. 표 빈칸은 그 검사들이 못 잡았다. Closes 가 없다. 2356 은 이미 2361 로 닫혔다. 2357 은 잘못된 가지라서 다시 열지 않는다. 사용자 길이로는 이미 있는 표시를 문서에서 못 찾는 구멍이라서 32. 카탈로그 팁은 Ox Alpha x-preview-f-free + deepseek-v4-flash-vision-exp. Cursor 정적 카탈로그는 opus-4-8-fast / opus-5-fast. 2334 CursorCredentialRouter 는 여전히 src/providers/cursor-pool.ts 모듈+테스트만 있고 어댑터에 연결되지 않았다. 2332 H2 는 discovery 전용. 2320 overflow + 2342 는 이미 dev. 2188 사이드카는 이미 dev. 2382 데스크톱 앱 재시작은 이미 dev. 2292 는 아직 연다.

docs-site/src/content/docs/reference/configuration/providers.md 라인 104 - 지금 HEAD 는 별칭만 적는다. 칸을 빼라는 표시 말이 없다
docs-site/src/content/docs/reference/configuration/providers.md 라인 105 - 모델별 칸도 같다. 이 PR 이 말을 넣지만 줄 앞에 빈칸이 붙는다
docs-site/src/content/docs/ko/reference/configuration/providers.md 라인 91 - 한국 문서도 HEAD 는 별칭만 적는다. 여덟 나라 모두 같은 빈칸이다
src/types/provider.ts 라인 367 - HEAD 주석은 별칭만 적는다. 이 PR 이 표시를 적는다. 배럴이 아니라 잎이다
src/reasoning-effort.ts 라인 21 - 표시는 이미 HEAD 에 있다. 이 PR 은 동작을 안 바꾼다
tests/reasoning-effort.test.ts 라인 977 - 이미 잠겨 있다. 이 PR 은 시험을 안 만진다
GitHub CI - 위생과 타깃과 라벨은 통과. CodeRabbit 통과. 체크리스트 4/4. 표 빈칸은 못 잡았다

메인테이너의 판단이 필요한 지점

  • 표 앞 빈칸을 고치기 전에 머지할지. 지금은 새 문장이 표에서 빠진다
  • 주석의 위 모델 기본값 문장과 문서의 칸을 뺀다 문장을 한 쪽으로 맞출지. 동작은 같다
  • 2356 을 다시 열지 말 것. 코드는 이미 2361 로 들어가 있다

너의 추천
지금 머지하지 말 것. 표 앞 빈칸을 빼고 다시 올린 뒤에 본다. 동작을 바꾸지 말 것. 가드를 더 넓히지 말 것. 2356 은 이미 닫혔다. 2357 을 다시 열지 않는다. types.ts/config.ts 스플릿과 겹치지 않는다. 라벨은 그대로 둔다. 프리뷰 배포가 아니다.
