feat(qoder): bridge Codex-owned tools through MCP

[juzijia]

Closes #5270

Summary

• Add a minimal MCP tool bridge for Qoder so structured tool_use output is returned to Codex as Responses function_call items while Codex remains the sole owner of approval, sandboxing, and actual tool execution.
• Keep Qoder built-in tools disabled with --tools "" and --max-turns 1, preserve native tool call IDs, and support multi-tool continuation without adding a parallel execution layer.
• Add bounded, request-scoped MCP catalog staging. Deliberate catalog validation/admission failures fail locally with 400 / invalid_request_error / tool_catalog_invalid before Qoder is spawned; unexpected catalog-construction exceptions are no longer rewritten as client errors and instead propagate through the existing run-turn error path.
• Complete Qoder tool turns only from the CLI's explicit assistant.message.stop_reason === "tool_use" signal. The previous 300 ms quiet fallback is removed; silence is never treated as successful completion.
• Narrow unforced store:false retention to an explicit Qoder opt-in, and only when the completed response actually contains a pending function_call needed for a later previous_response_id + function_call_output continuation. Text-only Qoder responses and non-opted-in providers are not retained by this exception.
• Keep Qoder-specific policy under src/adapters/qoder/; shared changes are limited to reusable coding-agent bridge primitives and the minimum Responses continuation plumbing needed by the Qoder path.

Design notes

• buildCodingAgentToolCatalog owns a small CodingAgentToolCatalogError type for the six intentional catalog refusals: tool-count limit, invalid name/namespace, name-byte limit, per-definition byte limit, aggregate catalog-byte limit, and allowed-tools argv-byte limit. Qoder maps only that typed error to tool_catalog_invalid; other exceptions are rethrown unchanged.
• Tool-turn completion is event-driven. The shared parser can observe both message_stop and assistant.message.stop_reason === "tool_use", but each adapter selects one authoritative completion signal. The shared default remains message_stop; Qoder explicitly selects assistant_tool_use_stop.
• An authoritative Qoder stop with an incomplete tool call fails closed with protocol_error. There is no timer-based success path.
• Restricted store:false continuation eligibility is selected by the serving adapter via adapterNeedsToolCallContinuation; currently only Qoder opts in. Shared response state admits such an unforced store:false response only when that opt-in is present and the response contains an actual pending function_call.
• The retained entry keeps the existing unforcedStoreFalse replay gate, TTL, snapshot, spill/reload, and memory-budget controls. The Qoder eligibility option itself is not persisted. Kiro/Cursor forced continuation and passthrough force:true remain unchanged.
• Qoder catalog projection preserves wire identities and order. Schemas are preserved except for the Responses-only encrypted marker stripped during projection.

Maintainer follow-ups

The current validated PR head addresses the four concerns raised in the maintainer review:

• Empty test catch {} hygiene issue: resolved.
• Broad Qoder catalog catch: resolved. Only CodingAgentToolCatalogError maps to 400 tool_catalog_invalid; unexpected exceptions propagate unchanged through existing run-turn error handling.
• 300 ms quiet fallback: resolved. Removed completely; Qoder completion uses explicit assistant_tool_use_stop.
• Provider-wide store:false retention: resolved. Qoder explicitly opts in, and retention additionally requires an actual pending function_call.

CodeBuddy is intentionally unchanged beyond the shared bridge primitives already required by this PR; its separate broad-catch behavior is not expanded into this scope.

Verification

Current validated PR head: c79387474476be4d5c19b8b2fc50e5be7cc28fd4, based directly on dev at 0511f458f12674f63bf3b629a0523cee246d33a0.

The existing single implementation commit was rebased in place from the previously validated PR head 34a7dc94c8236247c1b5f1454e6da8ab8d20cc50 onto the current dev tip above. The PR number, review history, and one-commit implementation shape were preserved; no merge or extra implementation commit was added.

Validation on the local candidate used the existing FN safe-exec isolation, sequentially, with Bun 1.4.0 and no real-provider calls:

• Qoder adapter + Qoder MCP + shared CodeBuddy bridge focused tests: 97 pass, 0 fail across 4 files.
• Responses store:false continuation tests: 19 pass, 0 fail.
• Test-layout tooling after syncing onto current dev: 16 pass, 0 fail.
• CLI dispatch coverage for the overlapping src/cli/index.ts integration: 73 pass, 0 fail (including 12 new upstream tests).
• Total focused tests: 205 pass, 0 fail.
• GOMAXPROCS=2 bun x tsc --noEmit: PASS.
• bun run structure:check: PASS.
• git diff --check upstream/dev...HEAD: PASS.

The candidate was synchronized by rebasing the existing single implementation commit onto the exact current dev tip. The 19 upstream commits since the previously validated base e53c8077e40b6f540bf1e5d5791a55282466bfac overlapped only src/cli/index.ts, scripts/test-layout/layout.json, and tests/fixtures/test-layout-expected.json. The rebase applied without conflicts. All current upstream behavior and layout entries were preserved; all 24 non-overlapping PR files remain byte-identical, and the added/removed lines across all 27 PR files are unchanged.

Commands run sequentially through /home/orange/bin/safe-exec in the candidate worktree (Bun test isolation, one internal worker, unchanged 2 GiB resource limit):

bun run test --parallel=1 ./tests/providers/qoder-adapter.test.ts ./tests/providers/qoder-mcp-server.test.ts ./tests/providers/codebuddy-tool-bridge-turn.test.ts ./tests/providers/codebuddy-tool-bridge.test.ts
bun run test --parallel=1 ./tests/responses/responses-state-store-false.test.ts
bun run test --parallel=1 ./tests/test-layout-tooling.test.ts
bun run test --parallel=1 ./tests/cli/cli-dispatch.test.ts
GOMAXPROCS=2 bun x tsc --noEmit
bun run structure:check
git diff --check upstream/dev...HEAD

The full local suite was not run under the documented focused-validation exception: this is a bounded dev-sync task on a resource-limited FN host, and the author-authorized scope is focused regression coverage rather than the full suite. Broader and cross-platform coverage remains for current-head CI; unrun or approval-gated workflows are not claimed as passes.

Full-suite, stress, and new real-Qoder/provider calls were not run. Historical real-provider observations are not claimed as validation of this candidate.

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:

• Required local validation passed; commands, results, and any full-suite exception are documented.

• I pushed my PR to a recent dev commit (at most 10 behind; a maintainer may still ask for the exact tip before merge).

Summary by CodeRabbit

• New Features

  • Qoder can use selected tools through an isolated, request-scoped MCP server. Invalid or oversized tool catalogs are rejected before Qoder starts.
  • Qoder tool turns complete only after a completed tool-use signal; silence and incomplete turns do not count as completion.
  • Responses marked store:false can be retained for matching function-call continuations, while text-only responses are not replayed.

• Documentation

  • Updated Qoder provider guidance to describe tool support; image input remains unsupported.

📝 Walkthrough

Walkthrough

Qoder now exposes selected client-declared tools through a request-scoped MCP server. Its coding-agent turn captures assistant tool-use frames and completes tool calls at the configured stop signal. Response state retains eligible unforced store:false function calls for matching continuations, including across spill and snapshot operations.

Changes

Qoder tool-call compatibility

Layer / File(s)	Summary
Catalog validation and MCP serving src/adapters/coding-agent/tool-catalog.ts, src/adapters/coding-agent/mcp-server.ts, src/adapters/codebuddy/mcp-server.ts, src/adapters/codebuddy/tool-bridge.ts, src/types/tools.ts, src/types.ts, src/cli/index.ts, tests/providers/qoder-mcp-server.test.ts, scripts/test-layout/layout.json, tests/fixtures/test-layout-expected.json	The catalog filters tools by toolChoice, validates names and size limits, and builds namespaced definitions. The shared MCP server advertises catalog tools without executing calls. CodeBuddy delegates serving to the shared helper, and the CLI handles the Qoder MCP entrypoint.
Qoder tool-call capture and turn handling src/adapters/qoder/adapter.ts, src/adapters/qoder/scaffold-guard.ts, src/adapters/coding-agent/protocol.ts, src/adapters/coding-agent/turn.ts, docs-site/src/content/docs/guides/providers.md, structure/providers-and-adapters.md, tests/providers/qoder-adapter.test.ts	Qoder configures a request-scoped MCP bridge when selected tools or a required tool call are present. The coding-agent turn parses assistant tool-use frames, maps tool names in history, and completes the tool turn at the configured stop signal. Tests cover catalog validation, capture, replay, and completion conditions.

Unforced store:false continuation

Layer / File(s)	Summary
Continuation eligibility and replay src/responses/state.ts, src/responses/state/unforced-store-false.ts, src/responses/spill-store.ts, src/responses/state/snapshot-codec.ts, src/responses/state/spill-queue.ts, src/responses/state/metrics.ts, tests/responses/responses-state-store-false.test.ts, scripts/test-layout/layout.json, tests/fixtures/test-layout-expected.json	Response state retains unforced store:false responses with pending function calls. It carries the marker through spill and snapshot paths, and expands replay only for output matching a stored call ID. The state metrics aggregation is implemented in a separate module.

리뷰 · 우선순위 64 / 80

이 PR은 Qoder가 Codex가 준 도구를 “실행”하지 않고, “이런 도구를 쓰고 싶다”는 신호만 다시 Codex로 돌려보내게 만듭니다. 베이스는 dev입니다. 이슈 #5270을 닫는 방향입니다.

지금은 Qoder를 --tools "", --max-turns 1로 켜서 도구가 막혀 있습니다. 그래서 Codex/Responses 쪽에 도구가 있어도 Qoder 경로로는 이어지지 않았습니다. 이번 변경은 요청마다 작은 MCP 목록만 잠깐 만들고, Qoder에게는 그 목록만 보여 줍니다. Qoder가 tool_use를 내면 OpenCodex가 그걸 Responses의 function_call로 바꾸고, 승인·샌드박스·실제 실행은 그대로 Codex가 합니다. 목록이 이상하거나 너무 크면 Qoder를 켜기 전에 로컬에서 400 tool_catalog_invalid로 막습니다. 또 store: false인데도 아직 맞춰야 할 function_call이 있으면, 그다음 function_call_output을 잇기 위해 응답을 잠깐만 기억합니다. 글만 있는 store: false는 예전처럼 안 남깁니다.

공통 쪽은 CodeBuddy가 쓰던 MCP 캡처 서버를 coding-agent로 빼고, 카탈로그·턴·이름 매핑을 같이 씁니다. requiresToolCall은 src/types/tools.ts로 모았고 CodeBuddy 쪽 복사본은 지웠습니다. 테스트는 Qoder 어댑터·MCP·store:false 쪽이 많이 늘었고, 작성자 기준 포커스 테스트와 tsc·structure:check는 통과했다고 적혀 있습니다. 다만 PR은 아직 draft이고 체크리스트는 0/4입니다. dev보다 5커밋 뒤이고, 리베이스 뒤 전체 스위트는 다시 안 돌렸다고 본문에 적혀 있습니다. CI 체크는 이 브랜치에 아직 안 보입니다. #5950(Qoder 클라이언트 연동)은 다른 주제라 이 PR과 바꿔 닫을 대상이 아닙니다. types/config 중복으로 닫을 PR도 없습니다.

라인 - tests/providers/qoder-adapter.test.ts · try { stdout.destroy(); } catch {} · 비어 있는 catch라 hygiene empty_catch가 막습니다. 고의면 한 줄 주석을 남기거나, 이미 닫힌 스트림은 무시해도 된다고 적어 게이트를 통과시키세요.

라인 - src/adapters/qoder/adapter.ts · buildCodingAgentToolCatalog를 감싼 catch {} · 이름/크기 오류뿐 아니라 예상 밖 예외도 전부 tool_catalog_invalid로 바꿉니다. 목록 검증 실패와 내부 버그를 나누지 않습니다.

라인 - src/adapters/qoder/adapter.ts · QODER_ASSISTANT_TOOL_QUIET_FALLBACK_MS = 300 · message_stop이 안 오면 0.3초 조용한 뒤 도구 턴을 끝냅니다. 도구 블록 사이에 CLI가 더 느리면 이르게 끊을 수 있고, 타이머에 기대는 계약이라 환경에 따라 흔들릴 여지가 있습니다.

라인 - src/responses/state.ts · rememberResponseState · 출력이 function_call이면 store: false여도(강제 저장이 아니어도) 이어서 쓰려고 남깁니다. Qoder만이 아니라 Responses 공통 동작이 바뀝니다. unforcedStoreFalse 재생 가드는 있지만, 남는 양과 TTL 영향은 전체 경로에 걸립니다.

메인테이너의 판단이 필요한 지점
Qoder에 MCP로 “목록만 보여 주고 실행은 Codex” 구조는 #5270에 맞습니다. 다만 store: false 예외 기억이 전 제공자 공통으로 넓어진 점이 이 이슈 범위에 필요한지, 300ms quiet fallback을 제품 계약으로 둘지가 갈립니다. draft·hygiene·dev 5커밋 지연·헤드에서 전체 스위트 미실행도 같이 보면 됩니다.

너의 추천
방향은 맞습니다. 먼저 empty catch를 고치고 체크리스트를 채운 뒤, dev에 맞춰 리베이스하고 헤드에서 최소 포커스+관련 Responses 테스트를 다시 돌리세요. catch는 카탈로그 검증 오류만 tool_catalog_invalid로 두고, quiet fallback은 실기기에서 한 번 더 확인한 값을 주석/테스트에 고정하는 편이 좋습니다. 공통 store: false 예외는 메인테이너가 “전 경로 OK”라고 하면 유지, 아니면 Qoder/브리지 경로로 더 좁히세요. 미리보기 배포 이야기는 필요 없습니다.

[Ingwannu]

Current-head intake checkpoint, not approval: head 16dcaee, dev base 33185c2. I saw the updated Verification section and 4/4 readiness attestation; the earlier a82740e verification wording is no longer the current description. The reported 235 focused passes/typecheck are author evidence, not tests I independently ran.

In the inspected stop-handling source, the 300ms quiet-success fallback is absent, and both the stream-loop synthesis and EOF check use sawSelectedToolTurnStop. Qoder selects assistant_tool_use_stop; CodeBuddy's default remains message_stop. This addresses the two earlier CodeRabbit stop-condition concerns at source level, but is not runtime or native-CLI verification by me.

I prepared an exact-head isolated review worktree but deferred local test execution because another host's-workspace workload was already running typecheck/E2E processes. I did not overlap test jobs, raise resource limits, kill that work, or call the real provider/CLI. No new scan was initiated.

Remaining gates: Cross-platform CI 37203140685, Service lifecycle 37203140667, and React Doctor 37203140682 are action_required, not completed passes. Required current-head CI and explicit boundary-review/sponsorship obligations remain separate from the readiness boxes. The shared unforced store:false retention is also broader than Qoder and survives snapshot/spill reload: the owner's scope decision raised in the earlier maintainer comment is not established by this static checkpoint or author attestation. No PR approval, integration, or issue closure is being recorded here.

[lidge-jun]

Thanks for the bridge, @juzijia. Maintainer review found a few defects on the Qoder path and in the merged result. I pushed the fixes to this branch rather than asking for another round. Final head: f962dfea85.

• 864d4b4bf5: Only Qoder projects prior tool calls with CLI-emitted (mcp__…) names, through projectHistoryToolNames. CodeBuddy history keeps the bare request name byte for byte. The commit also compacts two test-layout registrations and rewraps the Qoder catalog paragraph, because the merge with dev pushed layout.json to 2,000 lines and structure/providers-and-adapters.md to 602.
• c05091b966: Restricted store:false continuation now covers custom_tool_call/custom_tool_call_output as well as function calls. Complete assistant tool calls and the synthesized done(tool_use) require a validated system/init handshake. Complete calls are charged to the translator budget like partial ones. Completed call IDs are tracked.
• 8b6ca4d9a8: Complete and partial representations share one identity ledger. An exact repeat is suppressed, and a conflicting reuse fails with protocol_error in either order. Restricted replay fails closed when providerOutputStart is missing or invalid, including after snapshot hydration and spill reload.
• 3a217f92c9: Merge of dev (the branch was still at 2.78.0, which fails release-version-line), followed by 5465e1dbc9 to fit the line budgets again.
• 5e311003b8 / f962dfea85: Distinct call IDs count toward the 16-call turn limit separately from open blocks, so an open exact repeat doesn't take a slot. Open capture blocks keep their own 16-block bound, and names are validated before any allocation.

Each step was checked by an independent exact-head review, and the final head was approved. Focused Qoder, CodeBuddy and Responses-state tests, typecheck, structure:check, the file-size ratchet and the test-layout guards pass locally. Hosted CI on f962dfea85 is running.
