Summary

  • Add contextual Code Mode guidance for routed non-OpenAI models when the effective freeform exec description declares the nested apply_patch helper.
  • Prefer the native exectools.apply_patch path for targeted edits, while retaining exec_command for reads, tests, builds, formatters, and mechanical transformations when that helper is declared.
  • Suppress edit guidance for Plan Mode, mutation prohibitions, incompatible tool choices, structured or namespaced exec, and ambiguous OpenAI-branded destinations.
  • Centralize strict canonical OpenAI/ChatGPT route detection so native routes keep their existing messages and tool contract unchanged.

No public configuration or transport surface changes. No synthetic edit tool is introduced.

Verification

  • bun run typecheck
  • bun test tests/tool-catalog-nudge.test.ts tests/adapter-usage.test.ts tests/adapter-tool-conformance.test.ts — 55 passed, 0 failed
  • bun run test — 13,431 passed, 10 skipped, 0 failed on latest dev
  • bun run privacy:scan
  • bun run lint:gui:if-changed — skipped; no GUI changes in push range
  • bun run doctor:gui:if-changed — skipped; no GUI changes in push range
  • git diff --check
  • Normal git push with the repository pre-push hook completed successfully.

Checklist

  • Scope stays focused and avoids unrelated cleanup.
  • Docs or release notes were updated when needed. (No user-facing configuration or API changed; focused regression tests document the behavior.)
  • Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults.

Review readiness checklist

  • 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.
  • My PR is ready for review.

Summary by CodeRabbit

  • Improvements
    • Tool guidance now better reflects system instructions, developer directions, and recent user requests.
    • Tool descriptions are used to provide more relevant assistance.
    • Code-mode guidance can offer targeted patch suggestions when appropriate.
    • Patch guidance is automatically withheld when plans, restrictions, or unsupported tool types make changes unsuitable.
    • OpenAI-compatible routing is identified more accurately, improving provider-specific behavior.

Review Change Stack

📝 Walkthrough

Walkthrough

The PR adds shared instruction extraction and canonical OpenAI route detection. Provider adapters pass extracted instructions into tool-catalog nudge generation. Code-mode nudges use tool descriptions and conditional nested-helper guidance. Tests cover routing, extraction, and suppression rules.

Changes

Tool-catalog nudge behavior

Layer / File(s) Summary
Instruction extraction and contextual guidance
src/adapters/tool-catalog-nudge.ts
Adds effectiveInstructionText, route checks, tool descriptions, and conditional nested-helper guidance for apply_patch and exec_command.
Provider adapter integration
src/adapters/anthropic.ts, src/adapters/command-code.ts, src/adapters/google.ts, src/adapters/openai-chat.ts
Passes effective instructions into nudge construction and uses shared canonical native OpenAI route detection.
Route and guidance validation
tests/tool-catalog-nudge.test.ts
Tests route classification, structured instruction extraction, contextual patch guidance, and suppression conditions.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to e0126

The change can still present edit instructions when users explicitly prohibit file mutations, and some declared helper shapes may prevent valid edit or command guidance. This could lead routed models to choose inappropriate actions, so the PR is not merge-ready until these bounded correctness issues are fixed or explicitly accepted.

리뷰 · 우선순위 58 / 80

라우팅된 비-OpenAI 모델이 Codex Code Mode의 exec 안에서 중첩 tools.apply_patch를 쓰도록 안내를 붙이는 수정이다. 대상은 src/adapters/tool-catalog-nudge.ts고, Anthropic/Google/command-code/openai-chat 어댑터가 effectiveInstructionText(...)를 같이 넘긴다. 정규 ChatGPT/OpenAI 네이티브 경로는 isCanonicalNativeOpenAIRoute()로 빼서 기존 메시지/툴 계약을 유지한다. types.ts/config.ts 분할이랑은 안 겹친다. 닫거나 리베이스 시키라는 쪽이 아니다.

핵심은 카탈로그에 apply_patch가 탑레벨로 안 보여서 라우팅 모델이 python/heredoc으로 파일을 고치던 구멍이다. declaredToolsBlock()exec description 안의 const tools: { ... }를 파싱하고, apply_patch(input: string)이 선언돼 있을 때만 패치 안내를 붙인다. 본문에 이름만 있는 경우는 안내를 안 넣는다. exec_command가 같이 선언돼 있으면 읽기/테스트/빌드/포맷은 중첩 tools.exec_command로 보내라고 덧붙인다.

안내를 끄는 조건도 코드에 있다. Plan Mode, mutation 금지, do not use apply_patch, structured/namespaced exec, toolChoice로 막힌 경우는 targeted code edits 문장을 안 붙인다. shouldInjectNonOpenAIToolCatalogNudge는 hostname 라벨에 openai/chatgpt가 있으면 공격적인 비-OpenAI 정책을 넣지 않는다. api.openai.com.proxy 같은 애매한 목적지는 native로 취급하지 않으면서 nudge도 안 넣는다.

점수는 58이다. 라우팅 툴 호환은 지금 dev가 받는 축이 맞고, review-ready에 테스트도 tests/tool-catalog-nudge.test.ts에 붙어 있다. 다만 native-main/Windows 불(#2108 #2114)이 아니라서 80이 아니다. 합성 edit 툴을 새로 만든 것도 아니고, 공개 설정 표면도 안 건드린다.

해결방안은 이 PR을 지금 경로 그대로 머지하는 쪽이다. CI만 초록이면 된다. 머지 전에 볼 건 정규 라우트 판정이 openai-chat+key+api.openai.com / openai-responses+forward+chatgpt.com/backend-api/codex만 true인 점, 그리고 Plan/mutation 게이트가 실제 Codex 시스템 프롬프트 문자열과 맞는지다. 분할 3개(#2019 #2023 #2036)보다 먼저 넣어도 된다. 파일 겹침이 거의 없다.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Suppress edit guidance for all explicit read-only instructions.

At Line 220, the suppression expression does not match read-only, do not make changes, or no file modifications. The function then reaches the edit guidance at Line 225 even when the effective instructions forbid mutations. Extend the mutation-prohibition classifier for equivalent no-change wording, and add focused regression cases in tests/tool-catalog-nudge.test.ts.

This conflicts with the PR objective to suppress guidance for mutation prohibitions.

Thank you for this, @louis-tepe — the problem you identified is real: routed Code Mode sessions do not get the same edit guidance that native ones do, and that is worth fixing.

We are not going to absorb this implementation, and I want to be specific about why rather than leave you guessing.

The change is presented as prompt guidance, but src/adapters/openai-chat.ts:548 replaces the local "hostname is exactly api.openai.com" test with the new isCanonicalNativeOpenAIRoute predicate from src/adapters/tool-catalog-nudge.ts:118-132. That predicate is not prompt-only. The same value flows into:

  • messagesToChatFormat (openai-chat.ts:629), which decides whether developer messages stay as ordered role: "developer" entries or fold into the leading system message;
  • toolChoiceToChatFormat (:1232-1246), which decides whether a single required tool becomes a forced named function;
  • buildRequest (:1333), which decides native reasoning_effort versus gateway-style reasoning.

So a redefinition of "native route" made for guidance purposes silently moves three wire semantics that have nothing to do with guidance. Those are covered today by tests/cl01-openai-chat-review-regressions.test.ts:25-99, and reasoning about the new predicate's correctness means reasoning about all three at once.

There is also a narrower issue worth recording. codeModeExecName is withheld when a bare shell bridge is present (tool-catalog-nudge.ts:203-207), but the new suffix injection gates only on codeModeExecTool (:214-218). A freeform exec sitting beside a top-level exec_command would therefore receive "targeted code edits" guidance even though this repository's own predicate classifies that catalog as not Code Mode — the contract pinned at tests/tool-catalog-nudge.test.ts:114-123.

The shape we would take is a Code Mode / tool-description seam that adds the patch guidance without touching native route identity, so the guidance decision and the wire-format decision stay independent. If you would like to pursue that, the issue is still open ground and we would review it gladly.

Closing this one. Thanks again for the report and for the unit tests you wrote alongside it.
