Summary

  • Bridge provider-emitted exec_command, shell_command, and apply_patch helper calls through the request-declared Code Mode exec tool.
  • Compile helper arguments into nested tool calls as serialized data, preventing command or patch text from being evaluated as generated JavaScript.
  • Normalize decorated patch envelopes before invoking the nested apply_patch helper.
  • Keep streaming events, buffered JSON, undeclared-tool admission, and previous_response_id history on the same client-visible exec representation.
  • Preserve exact and namespaced tool declarations, keep unknown tools fail-closed, and add no retries or provider-specific hot-path branches.

Verification

  • bun run typecheck
  • 186 targeted compatibility and guard tests passed across 7 files.
  • On the latest dev, the bounded main lane reached 14,974 passed and 12 skipped. Its two failures are pre-existing 1-second/5-second WebSocket watchdog timeouts in server-auth.test.ts, outside this diff.
  • A detached, unmodified origin/dev control worktree reproduces the persistent 1-second server-auth timeout; the 5-second matrix also timed out twice there before passing on retry.
  • The other deadline-sensitive WebSocket files passed on isolated rerun: the provider-option integration passed, and all three native-profile drain tests passed.
  • All six repository-defined serial lanes passed in an earlier full-suite run; a later loaded run also showed only watchdog retry noise before those lanes.
  • bun run privacy:scan
  • Installed-package runtime smoke verified that decorated patch envelopes are canonicalized before the nested helper call.
  • bun run lint:gui:if-changed (skipped: no GUI changes)
  • bun run doctor:gui:if-changed (skipped: no GUI changes)

Review findings

  • Fixed the valid patch-envelope normalization finding and added execution-level coverage.
  • Verified the streaming undeclared-tool finding against the existing normalization path. The guard already classifies helper aliases through the declared exec name; streaming continuation coverage now proves the turn is accepted, cached, and replayable without adding another per-frame parse/restore pass.

Checklist

  • Scope stays focused and avoids unrelated cleanup.
  • Docs or release notes were updated when needed (not needed for this compatibility fix).
  • 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.

📝 Walkthrough

Walkthrough

The change adds Code Mode helper compilation for aliased exec calls. It normalizes apply_patch, exec_command, and shell_command across streaming, buffered, restored, and continuation-state responses.

Changes

Unified exec compatibility

Layer / File(s) Summary
Compile Code Mode helper inputs
src/responses/code-mode-helper-compat.ts, tests/legacy-shell-compat.test.ts
Helper payloads are unwrapped, shell fields are normalized, and valid inputs compile into apply_patch or exec_command calls. Malformed inputs remain data.
Normalize and restore routed calls
src/types/tools.ts, src/responses/custom-tool-compat.ts, src/server/responses-custom-tool-repair.ts, src/server/responses/core.ts, tests/responses-custom-tool-repair.test.ts, tests/responses-stream-tool-events.test.ts, tests/responses-undeclared-tool-guard.test.ts
Declared tool names resolve aliases to exec. Restoration handles function and custom calls, compiles aliased inputs, and persists normalized continuation state before undeclared-tool checks.
Translate streaming and buffered tool calls
src/bridge.ts, tests/bridge-legacy-shell-normalization.test.ts, tests/bridge.test.ts
Streaming and buffered calls retain helper names, suppress incremental helper deltas, compile completed inputs, and clear helper state after flushing.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: ⚪ Minimal · up to 71e18

The change bridges helper calls through the declared Code Mode exec tool while preserving streaming and continuation behavior; no actionable merge-blocking risk remains after normal checks and review.

설명

이 풀 리퀘스트는 제공자가 내보내는 exec_command, shell_command, apply_patch 호출을, 요청이 선언한 코드 모드 exec 도구로 다시 태웁니다. 지금 dev에서 코드 모드는 src/adapters/cursor/tool-definitions.ts 653-657줄이 말하듯, 셸과 파일 고침이 exec 본문 안의 중첩 헬퍼입니다. 바깥에서 exec_command를 직접 부르면 카탈로그에 없는 도구가 됩니다. 어떤 모델은 그 헬퍼 이름을 그대로 도구 호출로 내보냅니다. 그러면 가드가 거절하거나, 명령 글자가 자바스크립트처럼 평가될 위험이 있습니다.

새 파일 src/responses/code-mode-helper-compat.ts의 compileCodeModeHelperInput은 인자 객체를 JSON.stringify로 데이터로 만든 뒤, await tools.exec_command(...) 또는 await tools.apply_patch(...)와 text(result)를 붙입니다. 명령이나 패치 글자가 생성된 자바스크립트 안으로 섞여 들어가지 않게 하려는 선택입니다. src/bridge.ts 244-249줄의 freeform input 수리, src/responses/custom-tool-compat.ts, src/server/responses-custom-tool-repair.ts, src/server/responses/core.ts도 같은 표현을 스트림과 버퍼와 previous_response_id 역사에 유지한다고 합니다. 베이스는 지금 dev입니다.

다만 초안입니다. 본문도 전체 병렬 테스트가 14,895통과 뒤에 20실패와 5오류로 끝나지 못했다고 적습니다. 타임아웃과 호스트 부하 때문이라고 하지만, 합치기 전에 그 실패가 이 변경과 무관한지 다시 확인해야 합니다. 고립 재실행 174통과와 영향 파일 478통과는 방향이 맞다는 힌트이지, 회귀가 없다는 증명은 아닙니다.

생성되는 코드도 한 번 더 봐야 합니다. apply_patch는 JSON.stringify한 패치를 tools.apply_patch에 넘깁니다. 패치 본문이 이미 문자열인데 한 번 더 JSON 문자열이 되면, 호스트 apply_patch가 그 겉포장을 다시 풀지 않으면 거절합니다. shell_command의 command를 cmd로 옮기는 것은 맞지만, 잘못된 구조도 데이터로 통과시켜 중첩 도구 검증이 나중에 거절하게 합니다. 그 실패가 사용자에게 어떤 메시지로 보이는지는 이 리뷰 범위의 테스트 이름만으로는 부족합니다. src/types/tools.ts도 같이 바뀌므로, 선언되지 않은 도구를 닫는 규칙이 코드 모드 별칭 때문에 느슨해지지 않았는지 확인이 필요합니다.

경로/심볼 - 초안이고 전체 병렬 테스트가 20실패 5오류로 끝나 지금 dev에 합치면 안 됩니다.
src/responses/code-mode-helper-compat.ts - apply_patch 입력을 JSON.stringify로 한 겹 더 감싸면 호스트가 패치 봉투를 거절할 수 있습니다.
src/bridge.ts:247 - freeform 입력 수리와 새 헬퍼 컴파일이 같은 호출을 두 번 바꿀 수 있어, 스트림 미리보기와 최종 item이 달라질 수 있습니다.
src/server/responses-custom-tool-repair.ts - 수리 경로가 코드 모드 별칭을 넓히면 선언되지 않은 도구 가드와 겹칩니다.
경로/심볼 - 실패를 호스트 타임아웃으로만 설명하고, 이 변경이 원인인 실패를 걸러 낸 목록이 본문에 없습니다.

메인테이너의 판단이 필요한 지점

  • 제공자 헬퍼 이름을 exec로 다시 태우는 호환을 기본으로 둘지, 특정 제공자에만 둘지 정해야 합니다.
  • 전체 병렬 테스트가 깨끗해질 때까지 초안을 유지할지, 고립 테스트만으로 합칠지 정해야 합니다.
  • apply_patch를 JSON 데이터로 감싸는 것과 기존 봉투 수리가 한 경로여야 하는지 정해야 합니다.

너의 추천

초안을 유지하고 지금 합치지 마세요. 전체 테스트가 이 브랜치에서 깨끗이 끝난 뒤, apply_patch와 shell_command의 생성된 exec 본문을 사람이 읽고 한 번 더 고정하세요. 체크리스트가 채워지기 전에는 리뷰 완료로 보지 마세요. 미리보기 배포는 계획에 없습니다.

Approved at exact head 71e182ae63b773893c53982e2a9ad5a26d818e11. I verified that nested exec_command/shell_command payloads remain serialized data, shell_command.command is mapped to cmd, and apply_patch is passed as one normalized string argument rather than an extra JSON envelope. Streaming, buffered, previous-response restoration, and undeclared-tool guards use the same compiler without double repair. Exact-head focused validation passes locally: 176/176, plus typecheck and diff check. Merge only after required exact-head repository CI is green.

Independent audit found three overconfident claims: the compile gate ran on stale PR heads (4-294 commits behind dev), lidge-jun#2684 and lidge-jun#2690 do conflict on src/adapters/openai-chat.ts, and "lidge-jun#2663 CI green" cites the same five non-compiling checks that let lidge-jun#2694 ship five tsc errors.
lidge-jun added a commit that referenced this pull request Aug 27, 2026
Providers that advertise Code Mode can emit a bare helper call — exec_command,
apply_patch — instead of wrapping it in the code-mode exec envelope the client
declared. The bridge then relays a call the client never declared, and the turn
fails on an undeclared-tool guard or an invalid custom_tool_call.

Squashed from #2663 by Eleven-is-cool, whose implementation is taken whole:

- src/responses/code-mode-helper-compat.ts synthesizes the exec wrapper for a
  bare helper call
- custom-tool-compat and responses-custom-tool-repair carry the repair through
  the non-stream and repair paths
- the undeclared-tool guard keeps its fail-closed behavior for anything that is
  not a recognized helper

Landed as one commit rather than a 12-file merge so the history has a single
revert point for a change on the shared request path.

Tests: legacy-shell-compat, responses-custom-tool-repair,
responses-undeclared-tool-guard, bridge, bridge-legacy-shell-normalization and
responses-stream-tool-events — 176 pass / 0 fail. tsc clean.

Note for the record: this PR's five green checks (CodeRabbit, enforce-target,
hygiene, label, resolve-pr) compile and test nothing — the same five that let
#2694 ship five tsc errors. The evidence here is the merged-tree typecheck and
the suites above, not the badges.

Closes #2663

fix(responses): bridge bare code-mode helper calls through exec (#2663)
@lidge-jun

Landed on dev as cebe005db (PR #2724), squashed into the single commit cb9bb9b76.

Taken whole — the implementation is yours, unchanged. It went in as one commit rather than a 12-file merge because it touches the shared request path (src/server/responses/core.ts, src/bridge.ts), and a change there is worth having a single revert point for. Squash fidelity was verified by tree comparison, not by eye: the committed tree matches git merge-tree dev pr-head exactly.

The part that made this straightforward to accept is compileCodeModeHelperInput. Provider text is serialized as data via JSON.stringify and never interpolated into the generated source, and a malformed structured payload is passed through as data so nested-tool validation rejects it rather than the bridge evaluating provider text as JavaScript. The alias path is also gated on declaredNames, so the undeclared-tool guard stays fail-closed for anything the client did not declare — that was the property I most wanted to confirm before landing a bridge change.

Verification at the merge commit:

  • bun run test (full suite) — exit 0
  • bun x tsc --noEmit — clean
  • 176 pass / 0 fail across legacy-shell-compat, responses-custom-tool-repair, responses-undeclared-tool-guard, bridge, bridge-legacy-shell-normalization, responses-stream-tool-events
  • PR CI 23/23 green (one rerun for the known update-stop-first launcher-recovery flake, which this diff does not touch)

One note worth passing on: this PR's five green checks — CodeRabbit, enforce-target, hygiene, label, resolve-pr — compile and test nothing. They are the same five that let #2694 ship five tsc errors behind a green badge. Your change was fine, but it was fine on the evidence of a merged-tree typecheck and the suites above, not on those check marks.

Thanks for the fix.
