Motivation

ocx doctor scans $CODEX_HOME/agents/*.toml for legacy model_fallback fields. When the agents path exists but is not a readable directory — for example a plain file left by a botched sync — readdirSync throws and the whole diagnostic aborts instead of degrading to a warning.

Description

  • scanCodexAgentRolesWithTomlModelFallback accepts an optional onListError callback, catches enumeration errors, and returns an empty list on failure.
  • runDoctor passes the callback and prints a [WARN] with the cause instead of crashing; the rest of the report still runs.

Tests

  • bun test tests/routing/subagent-model-fallback.test.ts — 64 pass; the new case writes a plain file at agents/ and asserts the scan returns [] while reporting the error through the callback.

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.

  • My PR is ready for review.

Summary by CodeRabbit

  • Bug Fixes
    • The doctor command now reports a warning when agent role scanning fails instead of displaying an incorrect success message.
    • Diagnostics continue safely when the agent configuration path is malformed, without aborting the report.
    • Related checks are skipped after an earlier scan failure to avoid duplicate warnings or misleading results.
    • Success messages appear only when scans complete successfully and find no per-role model fallback settings or missing model pins.

📝 Walkthrough

Walkthrough

Agent-role scans now report listing errors through optional callbacks. Doctor prints one warning for a scan failure, skips the dependent scan, and suppresses success output. Unit and integration tests cover malformed agent paths.

Changes

Agent-role scan error handling

Layer / File(s) Summary
Scan error callback
src/codex/subagent-model-fallback.ts
Both scan functions catch errors from listCodexAgentRoles, call onListError, and return [].
Doctor warning and validation
src/cli/doctor.ts, tests/routing/subagent-model-fallback.test.ts, tests/codex-integration/doctor.test.ts
runDoctor reports scan failures with [WARN], skips the second scan after the first failure, and prints [ok] messages only after successful empty scans. Tests verify callback delivery and malformed-path reporting.

리뷰 · 우선순위 70 / 80

ocx doctor가 $CODEX_HOME/agents/*.toml을 스캔할 때, agents가 디렉터리가 아니라 파일(잘못된 sync 잔재 등)이면 readdirSync가 던져 전체 doctor가 죽었습니다. 진단 도구가 한 섹션 때문에 abort되면 안 됩니다.

이 PR은 scanCodexAgentRolesWithTomlModelFallback / scanOpencodexDerivedCodexAgentRolesWithoutModelPin에 onListError를 두고 실패 시 []를 돌려줍니다. runDoctor는 [WARN]만 찍고 나머지 리포트를 계속 돌리며, 첫 스캔이 이미 실패한 경우 두 번째 스캔을 건너 이중 경고·가짜 ok를 막습니다. unit·doctor e2e 테스트가 “파일인 agents” 케이스를 고정합니다.

현재 enforce-target fail·일부 체크 pending입니다. 코드 자체는 좁고 안전합니다. types/config 스플릿과 무관.

경로 subagent-model-fallback.ts try/catch + onListError - doctor 전용 관측 콜백이 라이브러리 기본 동작을 안 바꿈(미전달 시 빈 배열) — 호출부가 콜백을 안 주면 에러가 삼켜진다. doctor 경로는 콜백을 넘긴다
경로 runDoctor - 첫 실패 시 두 번째 스캔 skip이 맞다
테스트 doctor e2e + unit - 회귀 위치가 충분하다
enforce-target fail - merge 전 타깃/브랜치 게이트 확인 필요

메인테이너의 판단이 필요한 지점

  • onListError 없이 호출하는 다른 경로가 있다면, 예외를 삼키는 새 기본값이 괜찮은지(지금은 doctor가 주 소비자)
  • enforce-target fail 원인

너의 추천
enforce-target·호스티드 CI가 그린이면 merge. 콜백 없는 호출이 에러를 숨기지 않는지 한 번만 grep으로 확인하면 더 안심이다. types/config 스플릿으로 닫을 PR이 아니다.

추가 리뷰 · 우선순위 72 / 80

이전 리뷰(## 리뷰 · 우선순위 70 / 80) 이후 tip에 커밋 24672e63가 올라왔습니다. 코드 본문(doctor의 roleScanError 가드, onListError 콜백)은 그대로이고, 바뀐 것은 doctor e2e 테스트 한 줄입니다.

이전에는 “WARN이 나오고 ok 문구는 없다”만 확인했습니다. 지금은 같은 WARN 문자열이 정확히 1번만 나오는지까지 toHaveLength(1)로 고정했습니다. 첫 스캔 실패 뒤 두 번째 derived-role 스캔을 건너뛰는 가드가 빠지면 경고가 두 번 찍히므로, 그 회귀를 테스트가 바로 잡아줍니다. 이전 리뷰에서 “이중 경고·가짜 ok를 막는다”고 본 부분을 테스트로 못 박은 셈입니다.

scanCodexAgentRolesWithTomlModelFallback / scanOpencodexDerivedCodexAgentRolesWithoutModelPin 호출처는 doctor·테스트뿐이라, 콜백 없이 에러를 삼키는 다른 경로 걱정은 작습니다. 푸시 직후라 CI는 다시 pending입니다. types/config 스플릿과 무관합니다.

경로 tests/codex-integration/doctor.test.ts - WARN 횟수 assert는 가드 회귀를 잘 잡는다
경로 src/cli/doctor.ts / subagent-model-fallback.ts - 이번 tip에서 본문 변경 없음
CI - 재실행 중; 이전 tip의 enforce-target 이슈가 남았는지는 그린 확인 후 판단

메인테이너의 판단이 필요한 지점

  • 재실행 CI(특히 enforce-target·호스티드 게이트)가 이번 tip에서 통과하는지

너의 추천
CI 그린이면 merge. 추가 본문 수정은 필요 없어 보인다. 이전 70점 리뷰의 본문 판단은 그대로 두고, 테스트 핀만 올라간 추가 리뷰다.

…ole scan

The agent-role scan threw when the agents path existed but was not a readable directory, aborting the whole diagnostic instead of degrading to a warning. scanCodexAgentRolesWithTomlModelFallback now accepts an optional onListError callback and returns an empty list on failure; the doctor report emits a [WARN] with the cause instead of crashing.
Extend the same tolerance to the derived-role scan, which shares the directory listing: scanOpencodexDerivedCodexAgentRolesWithoutModelPin accepts the onListError callback, and the report skips the second scan when the first already reported the listing failure instead of printing a false ok.
…once

The dependent derived-role scan shares the same directory listing; without the roleScanError guard a malformed path would warn twice. Pin the count so a regression that drops the guard is caught.

Repository CI has now run on this branch and it is fully green at the exact head 93829f0c6498cae027584081e635c6fe13e91a2d: test 1/4 through 4/4, macos 1/2 and 2/2, and the aggregate ci check all report success. Fork contributors cannot start that workflow themselves, so this is the run a maintainer approved on your behalf.

The PR is still a draft because none of the four review-readiness boxes in the description are ticked, and the gate only marks a contributor PR ready when all four are complete. Nothing on the maintainer side can tick them for you — the first box is an author attestation by design.

Two of the four you can now answer from the run above rather than from a local suite. The branch is also on a recent dev; if you rebase, please note that the gate binds completion to the exact commit the head pointed at, so a push after ticking sends the PR back to draft and resets the boxes.

The change itself reads correctly to me. Routing both role scans through one error callback, reporting the cause once, and skipping the second scan instead of printing a false ok is the right shape for an observe-only doctor section.
