fix(claude-agent-sdk): replace the ToS-violating claude -p turn with Anthropic's own harness

[robin-bially]

⚠️ What this PR is fixing, stated plainly

2.65.0 shipped a provider that was against Anthropic's terms. This PR is the correction. That row built a one-shot claude -p turn itself: the caller's prompt replaced the harness system prompt, the session and the harness tools were off, and a client that is not Claude Code drove the loop - the usage accounts get suspended over, and the loss lands on the operator rather than on OpenCodex.

This provider now runs the turn through Anthropic's own harness, the way Meridian does: the harness owns the session, the prompt and the sign-in, the caller's instructions are appended to its preset instead of replacing it, and the client's tool catalog arrives over an in-process MCP server that captures calls instead of executing them. Nothing impersonates Claude Code and no request is forged.

Safer is not clean, and this PR does not claim otherwise: the client is still not Claude Code, so the row stays a grey area, and anthropic-apikey remains the route without an interpretation question. Whether a subscription-for-a-foreign-client row should exist at all, and whether src/providers/claude-cli-identity.ts keeps shipping beside it, stay maintainer decisions.

Summary

• Rename, with a migration. The row shipped in 2.65.0 as claude-cli (feat(provider): add a Claude Code CLI subscription provider #5712), an id that named the transport it used to be and collided with the identity module of the same name. It is now claude-agent-sdk ("Claude Agent SDK (subscription)"), adapter key and module follow, and the retired id keeps resolving through DEPRECATED_PROVIDER_ALIASES. claude-provider-rename-migration moves the saved row, a custom-named row's adapter string and every cross-config reference the shared rewriter owns, and refuses with a warning where two rows would collide (two rows can describe two different sign-ins).
• The turn runs on the harness, with the client's tools. No argv, no staged prompt file, no --mcp-config: the adapter calls the SDK's query() with the preset kept and appended to, tools: [], settingSources: [], strictMcpConfig: true and persistSession: false, so no built-in tool, no CLAUDE.md, skill, hook, plugin or foreign MCP source, and no transcript in the operator's ~/.claude. The request's tool catalog is served from this process (type: "sdk"), which advertises the request's own JSON Schema, captures calls and never answers one, so approval, sandboxing and execution stay with the client.
• One new optional dependency, flagged for review. @anthropic-ai/claude-agent-sdk under optionalDependencies plus its platform package (the Claude Code build it drives, ~230 MB unpacked; its peers @modelcontextprotocol/sdk and zod are already runtime dependencies here). MAINTAINERS.md requires security review for dependency installation, so this PR does not claim it: hygiene reports unsponsored_surface on package.json/bun.lock until a maintainer applies maintainer-sponsored. That review, and nothing else, is what this PR is waiting for. A compiled single-file build cannot resolve the package out of $bunfs, so it drives the claude on PATH and reports cli_not_found when it is missing; both paths are in the provider guide.
• Every review finding is fixed, each with a regression. The seven rounds are summarised under Verification; the detail lives in the review comments.
• Docs, structure map and test layout follow the rename and the new transport. tests/claude-integration/ keeps its claude-cli file: that one pins the CLI client path, not this provider.

Verification

Head c05a9a186, base fde8eebd6, 0 commits behind dev. Change-scoped evidence:

• bun run typecheck clean; bun run structure:check, bun run privacy:scan, the file-size ratchet and git diff --check green.
• 231 pass / 0 fail across the ten focused files: claude-agent-sdk-adapter (62 tests: option assembly, fail-closed preflight, streaming, the bridge contract, and the process-ownership/teardown regressions of rounds two to eight), provider-registry-parity (62), claude-provider-rename-migration (9), adapter-registry-authority (6), adapter-tool-conformance (8), model-rename-migration (49), model-roster-seed-repair (8), file-size ratchet (9), plus the two layout guards (test-layout, test-layout-tooling) the shared layout files pull in.
• Live through a proxy started from this worktree, over /v1/messages, seeded with providerConfigSeed: text turn HTTP 200 in 2.71 s answering pong, tool turn HTTP 200 in 1.68 s returning {"type":"tool_use","name":"echo","input":{"value":"hello"}} with stop_reason: "tool_use", no harness process and no scratch directory left behind.
• Full graph: bun run test:changed at ed0ffd9d5 (base 8b23fe340) resolves 1440 files and finished in 269 s with 29030 pass / 71 skip / 22 fail. All twenty-two sit in the service-lifecycle and local-environment cluster this machine produces under load, and twenty-one of them pass when their files run alone (the files behind them: service SQLite home, service diagnostics, restart lease, serving runtimes, the Codex and Grok toggles, launchd repair, service ownership state, injection-model suggest - 399 tests, one failure). The twenty-second, the restart veto lease frees a service-manager child (#5760) > a supervised ocx start outside the process tree dies at a held lease, fails identically on the base commit with this branch absent and with OCX_SERVICE unset, so it belongs to this machine rather than this diff. A second full-graph run hit the runner's own 900 s ceiling because tests/codex-integration/codex-refresh.test.ts stalled at 794 s under the same contention, with the same failure list. Whole-suite coverage rests on that run plus the change-scoped set above.
• Review rounds, each verified against the code and fixed with a regression, all on the harness ownership seam: (1) retired adapter string, foreign-named row, scratch cwd, optional install; (2) harness lifetime - the SDK's performCleanup races its transport exit against 2000 ms, so the turn spawns and reaps the harness itself on a bounded TERM/grace/KILL ladder; (3) terminal frame delivered before cleanup, and a missing close read as a clean exit; (4) a launcher's exit read as the tree's exit; (5) accounting that did not bound spawns; (6) the lease released by the pipe reclaim the ladder caused itself; (7) the latch keyed on the settlement label instead of the tree call, plus a stale sweep comment; (8) the Windows tree terminator ran taskkill /T /F through execFileSync with no ceiling, so a stalled command could hold the event loop past the bounded teardown - each tree command now runs under a finite budget tied to the observation ceilings, and a timeout keeps the tree ownership and the unresolved-tree verdict.
• Union interactions with dev: the per-block parse state that landed on the base (fix: bug-PR merge train batch 8 (CodeBuddy parallel tool-use, ci-privacy-gate hang) #5945) changed what the completeness invariants compare, and fix(codebuddy): harden captured parallel tool blocks #6022 (strictToolBlockCapture and the cap moved to block open) plus fix(codebuddy): bound buffered tool calls #6081/fix(adapters): keep tool-call ID reminting linear (prevent quadratic DoS) #6083 (tool-state admission in the shared parser) had to be mirrored in sdk-turn.ts.
• Twenty-five rebases so far, each after the branch fell outside the gate's 10-commit tolerance. Two needed a real resolution. The twentieth is the wider one: dev landed the Zed adapter and added zed to the same two adapter rosters this branch renames claude-cli in, so the merged lists keep zed and carry the renamed id; only the rename commit's patch differs, and one later commit differs in context alone (the createZedAdapter import). The twenty-fifth was patch-identical end to end; the twenty-fourth needed only the rename commit's fixture line re-placed after dev packed test-layout-expected.json two entries per line; the other sixteen commits are patch-identical. The twenty-third and twenty-second were patch-identical end to end; the twenty-first apart from the rename commit context again (dev added opper, opengateway and tokenlab to the same parity list). The seventeenth is the first conflict of the series: dev's MiniMax roster step (#6304) and this branch's provider projection both edited src/providers/model-rename-startup.ts, and the merged version runs both, with the provider projection still first so every later pass keys on the canonical id. The eighteenth and nineteenth were patch-identical, the sixteenth was patch-identical too, and the fifteenth needed a per-file check: the only patches that differ from the previous head sit in files dev changed underneath them (tokenlab in the shared provider list, the 2.73.0 bump), with this branch's own lines unchanged and the parity test green.

Evidence for the destination

The preset list in contributing.md is answered against the harness contract rather than a vendor gateway. Destination, credential path and base URL are what 2.65.0 already shipped; what changes is who drives the turn.

• The harness is Anthropic's own. The Agent SDK documentation describes it as "a library that runs the Claude Code binary, with Claude Code's capabilities": https://code.claude.com/docs/en/agent-sdk/overview (checked 2026-09-26).
• The credential stays local, which the terms require ("You may not share your Account login information, Anthropic API key, or Account credentials with anyone else"). This provider runs the harness inside the operator's own process against the operator's own signed-in installation; it holds no credential of its own and forwards nothing: https://www.anthropic.com/legal/consumer-terms (checked 2026-09-26).
• The clause this sits against, stated plainly. The same terms prohibit accessing the Services "through automated or non-human means" except via an API key or where Anthropic otherwise permits it. The Agent SDK is an Anthropic client rather than a foreign script, which is why this PR moves the turn into it - but nothing here claims a ruling. anthropic-apikey remains the path without an interpretation question, and the row note says the same in the dashboard.
• No maintenance owner is claimed. The row is not newly added and this PR names nobody as its owner; breakage surfaces through the provider-compatibility issue template. If a named owner is a condition for the merge, that is a decision for whoever takes it on.
• The live runs above were made on 2026-09-26 against Claude Code 2.1.282.

Supply-chain review surface

Requested on 2026-09-27: eight items, every value read from the installed packages and the npm registry. Two items are the reviewer's decision rather than mine.

Provenance and license.

• @anthropic-ai/claude-agent-sdk@0.3.282, tarball https://registry.npmjs.org/@anthropic-ai/claude-agent-sdk/-/claude-agent-sdk-0.3.282.tgz, integrity sha512-6UAerS1udzndLEx+0XW3gQWiICgfu/a+2fx/aLY3gUy+1JUQESbwYkhR40+D6d+yjueCslkLmvkPlZQFZDph6A== - the same string bun.lock records and npm view ... dist.integrity returns, so registry and lock agree. The eight platform packages are pinned to 0.3.282 with their own sha512 values in the same file.
• Published 2026-09-24T15:53:58Z by wolffiex <wolffiex@anthropic.com>, repository anthropics/claude-agent-sdk-typescript. 0.3.283 was published 2026-09-25 and is already latest.
• No SPDX identifier anywhere in the chain, and the shipped binary is not under an open-source license. The SDK declares "license": "SEE LICENSE IN README.md" while the shipped text sits in LICENSE.md; each platform package's LICENSE.md is one line - "© Anthropic PBC. All rights reserved. Use is subject to the Legal Agreements outlined here: https://code.claude.com/docs/en/legal-and-compliance." Neither states redistribution rights.
• Sizes: the SDK is 5,121,927 bytes unpacked; the platform package is 222,245,896 bytes holding one 222,245,312-byte claude executable, mode 755.

Install behaviour. Neither package declares a lifecycle script - the SDK has no scripts field at all, the platform package neither - so installing them is tarball extraction plus sha512 verification. No vendor code runs during bun install.

Executable and update behaviour. Nothing is fetched at install time; the platform package contains the binary. At turn time the harness starts with DISABLE_AUTOUPDATER=1, CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC=1, CLAUDE_CODE_DISABLE_FEEDBACK_SURVEY=1, CLAUDE_CODE_DISABLE_OFFICIAL_MARKETPLACE_AUTOINSTALL=1, DISABLE_TELEMETRY=1, DISABLE_ERROR_REPORTING=1 and DISABLE_FEEDBACK_COMMAND=1 (src/adapters/claude-agent-sdk/env.ts): it does not replace its own binary under a running proxy and sends no usage or crash data.

Filesystem and network access. Import is a library load and nothing else. Probe on this head - HOME pointed at a fresh temp directory, a logging claude shim first on PATH, then bun -e 'import("@anthropic-ai/claude-agent-sdk")' - returned 32 exports, created no file under that HOME beyond Bun's own cache directory, invoked nothing through PATH and left no child process. Turn time is bounded by the option set: no built-in tools, no CLAUDE.md, skills, hooks, plugins or the machine's own MCP servers, no transcript, and an empty per-turn scratch cwd removed once the harness exits. What stays opaque is the vendor binary itself; the environment replacement, the option set and the scratch directory are the boundary this repository controls. If the binary's own runtime behaviour should be traced or run under a sandbox for the record, say so and I will.

Supported-platform fallback. The SDK declares eight os/cpu-gated platform packages as its own optional dependencies, all pinned to 0.3.282, so only the target in use is installed. A compiled single-file build cannot resolve the bundled copy out of $bunfs, so there the turn drives the claude on PATH and answers cli_not_found (500, non-retryable, with the install hint) when it is missing - the same requirement this row had before the SDK. Live Windows evidence for the taskkill /PID <pid> /T /F path is the one thing that cannot be produced from here: there is no Windows host and the fork's exact-head workflows sit at action_required. That path keeps unresolved-tree for a tree that cannot be walked from a dead pid and a probe answering "present", so capacity is retained rather than returned on a close that only speaks for stdio. Unverified here rather than claimed as tested.

Optional-install omission. The entry sits in optionalDependencies, so --omit=optional skips it. The adapter loads the SDK dynamically and maps a failed load to claude_agent_sdk_unavailable (500, non-retryable) instead of failing the proxy at startup, covered by tests/providers/claude-agent-sdk-adapter.test.ts.

Credentials and session boundary. OpenCodex stores no Claude token for this row, reads none and injects none, and never hands the configured API key to the harness (buildChildEnv ignores both). The SDK replaces the child environment with that map, and the shared base drops every inherited ANTHROPIC_* name - which is also what keeps a claude already pointed at this proxy from looping back into it. The only inherited name added back is USER, which is not a credential: the harness resolves its own sign-in by account name (measured with claude auth status under env -i - USER alone reports loggedIn: true, neither USER nor LOGNAME reports false). The sign-in is the operator's own (macOS Keychain, or ~/.claude/.credentials.json elsewhere) and is the account billed.

One open item that is the reviewer's call, not mine. A vendor binary under "all rights reserved" terms with no SPDX identifier is a different kind of optional dependency than the ones this repository already declares. If that is not acceptable here, the row goes back to requiring a claude the operator installed themselves and the dependency comes out.

Security architecture risk: 🟡 Moderate · up to 1c399

The new route puts the provider’s sign-in and requests under the vendor’s harness and limits which tools it can access. Existing provider settings also move to a new identity. These are meaningful control and rollout changes, although no introduced security failure was established.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — Any client permitted to use this subscription provider reaches the proxy operator’s harness sign-in, not a separate client sign-in. That shared-account property also applied to the retired subscription route; this PR changes the harness path, not the account owner.

Trust Boundaries and Controls

• observed — Request-supplied tool schemas cross into an in-process MCP catalog, but its call handler remains pending rather than executing tools. The runner checks initialization, declared names, call limits, and completion before handing calls back to the client.
• observed — The child environment does not add the configured API key; the harness instead uses the operator’s own sign-in. Destination validation precedes SDK startup.

Resilience and Maintainability Implications

• inferred — Local cleanup limits how long a request waits for query return, but the optional return method and bounded wait do not themselves prove that an unresponsive external harness has terminated.

Hardening Proposals

• proposed — Verify the external runtime’s process and MCP-server teardown guarantee when cancellation occurs and query return exceeds the cleanup bound.

리뷰 · 우선순위 64 / 80

이 PR이 하는 일은 두 갈래입니다. 한쪽은 코드에 들어와 있고, 다른 쪽은 글에만 있습니다.

들어와 있는 쪽은 이름 바꾸기입니다. 공급자 id가 claude-cli에서 claude-agent-sdk로 바뀝니다. 2.65.0에 들어간 옛 이름은, 예전에 쓰던 claude -p 한 번 호출을 가리켰고, 메시지 API용으로 claude-cli/<버전> 헤더를 만드는 claude-cli-identity.ts와도 이름이 겹쳤습니다. 저장해 둔 설정은 켜질 때 새 id로 옮깁니다. 목적지에 이미 행이 있거나 같은 키가 부딪히면 경고만 하고 원래 설정을 그대로 둡니다. 반쯤 고친 설정을 저장하지 않으려고 복사본에서 고친 뒤, 실패하면 그 복사본을 버립니다. 옛 id는 DEPRECATED_PROVIDER_ALIASES로 레지스트리 조회만 새 행에 연결됩니다. 베이스는 dev이고, 같은 일을 하는 다른 열린 PR은 없습니다. #5792와 #5757은 다른 수정입니다.

글에만 있는 쪽은 동작 바꾸기입니다. 제목, 가이드, 대시보드 note, structure 문서는 이제 이렇게 말합니다. 턴이 Claude Agent SDK 세션이고, 같은 대화는 이어서 하며, 사용자 지시는 하네스 프리셋 뒤에 붙고, 도구는 실행하지 않고 받아 두기만 하는 프로세스 안 MCP로 넘긴다. 어댑터는 그 문장과 반대로 남아 있습니다. buildArgs는 여전히 --no-session-persistence, --tools "", --strict-mcp-config, --system-prompt-file을 넣습니다. 세션은 끄고, 기본 도구는 비우고, 시스템 프롬프트는 프리셋을 파일로 갈아끼웁니다. 함수 이름도 createClaudeCliAdapter입니다. 테스트는 첫 인자가 -p인지 봅니다. PR 본문도 이 절반을 진행 중이라고 적어 두었고, 초안 체크리스트는 0/4입니다. 약관 경고 자체는 분명합니다. Claude 구독을 Claude Code가 아닌 쪽에서 쓰면 잠길 수 있고, 피해는 로그인한 계정에 간다고 적습니다.

src/adapters/claude-agent-sdk/adapter.ts buildArgs - 세션을 끄고, 도구를 비우고, 프롬프트를 --system-prompt-file로 바꿉니다. 문서가 말하는 SDK 세션, 지시 이어 붙이기, 캡처용 MCP와 다릅니다.

docs-site/src/content/docs/guides/providers.md Claude Agent SDK 절 - 세션을 이어 받고, 프리셋 뒤에 지시를 붙이고, 프로세스 안 MCP로 도구를 받는다고 이미 된 일처럼 적습니다.

src/providers/registry/entries-extended.ts note - 대시보드에 같은 설명이 나갑니다. 이대로 합치면 사용자는 아직 없는 동작을 안내받습니다.

structure/adapters/registry.md - 테스트가 tools: []와 MCP 옵션을 고정한다고 적혀 있습니다. tests/providers/claude-agent-sdk-adapter.test.ts는 args[0]이 -p인지 확인합니다.

src/providers/claude-provider-rename-migration.ts 경고 - 옮긴 뒤 "이제 Claude Agent SDK를 구동한다"고 말합니다. 지금 행은 예전처럼 CLI 한 턴입니다.

tests/adapters/adapter-tool-conformance.test.ts TOOL_LESS_ADAPTERS - 이 어댑터를 도구 없는 목록에 둡니다. 지금 코드와는 맞고, 새로 고친 문서와는 어긋납니다.

메인테이너의 판단이 필요한 지점

이 행을 제품에 남길지입니다. 글은 Anthropic 약관에 어긋난다고 이미 말합니다. 행을 뺄지, 경고를 단 채로 남길지는 메인테이너 결정입니다.

SDK라고 적은 문장을 어댑터보다 먼저 합칠지도 결정입니다. 이름 변경과 약관 경고는 지금 코드로 설명할 수 있습니다. 세션, MCP, 프롬프트 이어 붙이기는 그 코드가 들어오기 전에는 문서에 있으면 사실이 아닙니다.

옛 id는 getProviderRegistryEntry 안에서만 새 id로 바뀝니다. 설정 맵의 키를 문자열로 직접 찾는 코드는 별칭을 타지 않습니다. 목적지에 행이 있어 이주를 거절한 경우에는 옛 키가 그대로 남습니다. 그 정도로 조회가 다 덮이는지 봐 주세요.

너의 추천

초안인 채로 두세요. 가이드, note, structure 맵, 이주 경고의 동작 설명은 지금 어댑터에 맞추세요. 도구를 끈 claude -p 한 턴입니다. SDK 세션 문장은 그 코드가 들어온 커밋에 같이 넣으세요. 약관 경고 문단은 어느 쪽이든 남기세요. 이름 이주가 부딪히면 손을 떼고 원본을 두는 쪽은 그대로 두면 됩니다.

Review answered against 7092d61c8

The review's split was right for 959ef1f92: the rename was in the code, the behaviour change only in prose. 7092d61c8 moves the behaviour into the code, so the findings are resolved rather than argued away.

• buildArgs is gone. The adapter calls the SDK's query() (sdk-turn.ts); option assembly is sdk-options.ts (preset kept and appended to, tools: [], settingSources: [], no persisted session), factory is createClaudeAgentSdkAdapter.
• Docs, note, structure map, migration warning describe this code now; the structure claim is pinned by tests/providers/claude-agent-sdk-adapter.test.ts.
• Tool channel. The in-process MCP server in sdk-bridge.ts advertises the request's own schema, captures calls and answers none.
• TOOL_LESS_ADAPTERS stays. Those assertions read the buildRequest wire body; this adapter inherits contractParent: "codebuddy" and expresses no tools there, and its tool behaviour is pinned by the bridge tests.
• Alias coverage. One consumer (getProviderRegistryEntry), three documented paths in deprecated-provider-aliases.ts. Name a fourth and it gets covered.
• Maintainer calls stay yours: whether the row should exist at all, and whether claude-cli-identity.ts keeps shipping beside it.

The one open item is not code: unsponsored_surface on package.json/bun.lock from installing the SDK, which MAINTAINERS.md routes to security review and the maintainer-sponsored label. Everything else is done; the live evidence for both paths is in the description.

In `@package.json`:
- Line 80: Move `@anthropic-ai/claude-agent-sdk` from dependencies to
optionalDependencies so installs can omit it while preserving the existing
missing-SDK failure path, and regenerate the lockfile to match. Review the SDK’s
license terms before merging.

In `@src/adapters/claude-agent-sdk/sdk-options.ts`:
- Around line 90-119: Update buildAgentSdkTurnOptions to set Options.cwd from a
scratch-directory value supplied through AgentSdkOptionInput. Create an empty
directory with mkdtemp for each turn and remove it after the query is reaped;
update the options test to provide and assert the cwd value.

In `@src/providers/claude-provider-rename-migration.ts`:
- Around line 58-61: Update projectClaudeProviderRename so it moves the
claude-cli row and changes its adapter only when the row’s adapter is
claude-cli. Leave rows with other adapters, such as anthropic, and their
references unchanged, and emit a warning for those rows; add a regression test
confirming an anthropic row keyed claude-cli remains untouched.
- Around line 45-57: Update the migration flow so `claude-cli` adapter values
are rewritten before either refusal branch returns the original configuration,
allowing refused configurations to resolve through the exact `PROVIDER_REGISTRY`
lookup. Add a regression test that builds an adapter from a refused
configuration.

All four findings are addressed in c7a94f9e5

Each verified against the code and fixed with a regression; the dependency one in the form the review suggested.

• claude-provider-rename-migration.ts:61 (major) - taken. The projection moves only the row the retired preset seeded; a row merely carrying the retired name on another adapter keeps its name, transport and billing and gets a warning. Regression: leaves a user-named claude-cli row on another adapter alone.
• claude-provider-rename-migration.ts:57 (minor) - taken. getAdapterDefinition resolves through the same deprecation table, so a refused row still names a buildable adapter and the adapter string and provider id cannot disagree about claude-cli. Regression: a refused row still names an adapter the registry can build.
• sdk-options.ts:119 (security) - taken. Every turn runs in its own empty scratch directory (mkdtemp), passed as cwd and removed once the query is reaped; a directory that cannot be created fails the turn. Live text and tool turns still answer, no orphan processes, no directory left behind.
• package.json:80 - taken. The SDK moved to optionalDependencies, lockfile regenerated, missing-package path unchanged. The license half is the security review this PR asks a maintainer for (unsponsored_surface); this PR does not claim it.

Verification for this head is in the description.

[devin-ai-integration]

Maintainer triage: priority: P1 — replaces a shipped provider path that violates Anthropic terms (compliance; touches auth/credentials, needs security review).

Criteria (P1): High: reproducible failure in a core path (routing, failover, account pool, streaming, usage, auth, install) with no clean workaround; or a small (<300 LOC) bug-fix PR for such a failure.

[robin-bially]

This PR is waiting on a security review, and the gate cannot ask you for it

hygiene and enforce-target are red on 64bbcd18d for one code only: unsponsored_surface on package.json and bun.lock. The check is path-based and clears in one of two ways - both maintainer actions:

• Apply maintainer-sponsored after the review. The gate then lifts the draft itself and pings the maintainers.
• Take the branch over: a maintainer's own push is exempt by design, so the same change lands without the label (add a Co-authored-by trailer and I close this PR once yours carries it).

Worth knowing: the gate's maintainer notification only fires on a completed readiness gate, and this code prevents that completion - maintainersPinged is still false, so nobody was told it is waiting. The checklist is 4/4 and the branch is 0 behind dev.

What needs the review. The new optionalDependencies entry @anthropic-ai/claude-agent-sdk plus its platform package - the Claude Code build the adapter drives, ~230 MB unpacked. bun install is a no-op and the lockfile diff is exactly the section that entry moves. Everything else in the diff is the rename, its migration, docs, and the turn moving from a hand-built claude -p command line to the SDK's query().

Why the timing matters. 2.65.0 shipped the previous turn: opencodex built the claude -p invocation itself and stripped the session, so the account risk sat with the user - the pattern Anthropic blocks accounts for. This PR is the correction. It remains a grey zone, and anthropic-apikey is still the route without an interpretation question.

I have not applied the label and will not - that review is yours, not mine to declare.

[robin-bially]

Update 2026-09-27 - withdrawn. The maintainer response below is right: a maintainer-owned PR landing the same two files moves the same supply-chain decision instead of answering it, and the path gate is doing its job. The dependency stays in this PR's diff, and the review surface the reviewer asked for is collected in the description under Supply-chain review surface.

The proposal that stood here is withdrawn and dropped from this comment; what remains are the two maintainer options: maintainer-sponsored after the review, or carrying the branch outright.

[Ingwannu]

Scoped resource-lifecycle re-review at ed0ffd9, not a full dependency/authentication approval.

The previously reported late-parent-close interleaving is now addressed in source: settlement latches treeOwnershipUnsettled whenever the tree call failed, independently of the direct-parent running/unresolved-tree label, before local pipe reclamation. deliverExit and quarantine sweeping retain that ownership. I am not repeating the old reason-label-only finding against this head.

P2 — the production Windows tree terminator is outside the promised cleanup bound. In src/adapters/claude-agent-sdk/harness-process.ts, defaultKillProcessTree calls execFileSync(taskkill.exe, ... /T /F) with no timeout. Both the abort listener and the TERM/KILL ladder call it synchronously through requestTermination, before the bounded waitForClose observation. If taskkill stalls, the proxy event loop is blocked inside the OS command, so neither the grace/reap timers nor the turn cancellation can settle the cleanup. This bypasses the bounded teardown contract even though the subsequent waits have ceilings. The injected tree-result tests do not exercise this production command boundary.

Please give each tree command a finite execution budget tied to the teardown deadline (prefer an asynchronous bounded command if practical), treat timeout/failure as unresolved tree ownership, and retain the lease/scratch ownership rather than converting it to success. Add a command-runner regression that models a stuck terminator and verifies bounded settlement plus retained uncertainty. Do not relax the existing parent-close/descendant assertions.

This is a decisive source-level execution path, not a claimed reproduction of an actual Windows taskkill stall: I did not execute any real taskkill, harness, account flow or security scan. Real Windows descendant ownership evidence and the SDK dependency/license/provenance sponsorship decision remain separate holds. Existing broad author-local failures are not relabeled as clean by this scoped follow-up.

[robin-bially]

P2 addressed at 277d064.

defaultKillProcessTree no longer runs the Windows terminator unbounded. runTreeCommandWithBudget gives execFileSync a finite timeout plus killSignal: "SIGKILL" (the runtime's default SIGTERM can be ignored, and a terminator that ignores it would keep running behind the bound it just spent), and the supervisor derives each command's budget from its own ceilings - the smaller of the grace and reap windows, because a command still silent after one observation window is not going to answer, and the ladder must not wait on it longer than it waits on the child.

The call stays synchronous deliberately: the tree has to be walked before the direct child is killed, since taskkill /T needs a live root to walk from, and that ordering is what the ownership accounting rests on. A timed-out command throws like any other refusal, so it lands on the existing false verdict: the tree failure is recorded, the child keeps its cleanup lease, the scratch cwd stays in place, and the entry is named unresolved-tree instead of being rounded to success.

Regression, two cases: the command-runner seam now stands in for the production command boundary, and a stuck terminator that spends its whole budget and then throws pins the finite budget per pass (TERM and KILL), the tree-before-direct ordering, bounded settlement, and the retained lease; the second case runs the production runner against a real process that outlives its budget by orders of magnitude. Counter-proof: removing timeout/killSignal from the runner turns that second case red. The existing parent-close and descendant assertions are unchanged.

Local evidence on this head: typecheck, structure:check, privacy:scan and git diff --check green; the focused set is 231 pass / 0 fail across ten files; live /v1/messages text and tool turns answer (2.71 s / 1.68 s, no orphan harness, no scratch directory left). The head also carries a routine rebase onto b4616be (dev moved twelve commits; only the rename commit's context differs).

Scoped P2 resolved at 277d064: finite timeout and SIGKILL in the production tree-command runner; both focused bounded-termination regressions independently passed on Linux/Bun 1.4.0 under CPU/RAM caps. Other reviews and dependency/sponsorship/Windows gates are not withdrawn.

[Ingwannu]

Rechecked 277d064. The production runner now sets a finite timeout plus SIGKILL, and the supervisor supplies the minimum grace/reap budget before each tree call. I independently ran the two new tests (stalled tree terminator and production command runner) on Linux/Bun 1.4.0: 2 pass, 0 fail, 7 assertions, exit 0; other cases were filtered out. Execution was sequential, CPUQuota=75%, MemoryMax=1536M, swap disabled, private HOME/CODEX_HOME/OPENCODEX_HOME/TMPDIR. This resolves my latest unbounded-command P2, not the whole 29-file PR or actual Windows taskkill behavior. The current hygiene and quality job logs both name unsponsored_surface; I am not relabeling that as an infrastructure failure or granting sponsorship. Earlier independent/dependency/Windows ownership gates remain separate. No live Claude or security scan was run.

[robin-bially]

Closing this. The change is complete and tested on the current dev head, but it is blocked on the dependency sponsoring and the open policy question about a subscription-proxy row, and neither is moving. The branch stays in the fork if you ever want to pick it up.
