### Child isolation and the parent log
Each subagent runs in its **own `Session`** (own id, `parentSession` lineage), persisted independently. The parent's log records only the spawn `tool/call` and its `tool/result` (the child's final output) — the child's internal steps and tool calls stay in the child's own session, never injected into the parent log. This is the only design that is identical across transports: an ACP child's internal events physically cannot be injected into our parent log, so making in-process behave the same keeps the seam transport-agnostic.
Each in-process subagent runs in its **own `Session`** (own id, `parentSession` lineage), persisted independently. Remote ACP and one-shot product providers instead mint a parent-scoped lifecycle id and expose no local `Agent` or child `Session`; their internal state remains in the remote process. Across both forms, the parent's log records only the spawn `tool/call` and its `tool/result` (the child's final output), while child steps and tool calls remain outside the parent log.

Every run pays a fresh subprocess (spawn + `initialize` + `newSession`). The parent surfaces only the child's final answer: `session/update` thoughts and tool-call cards are consumed and dropped, and permission prompts never reach a human — the configured policy answers them. The child's environment is credential-scrubbed by default, so its own model key is supplied explicitly via `config.env`.
## Future providers
## Product-provider siblings
The same out-of-process spawn/prompt/stream/cancel shape generalizes to other transports named in the seam Agent Note — A2A, the Codex app-server, and the Claude Code Agent SDK — each a sibling provider registered by name. The ACP backend is the proof that the seam supports the boundary; those are mechanically similar.

Both plugins are included in the Python runtime closure. The persistent Bash closure also includes the PTY service/local backend and the sandbox services required by that backend. Because `node-pty` executes a native `spawn-helper` on macOS, each packaged macOS runtime executable ships with a `-spawn-helper` sibling; Linux uses `forkpty` directly. A pinned `node-pty` patch checks `DSH_NODE_PTY_SPAWN_HELPER` first, so it remains a true override for a current external consumer that supplies a non-sibling helper. When the override is unset, the patch resolves the packaged executable sibling if present and otherwise preserves upstream lookup in ordinary Node runs. The macOS builders fail before publication when the helper is absent or not executable.
The shipped [`core-web.cordis.yml`](../../../../apps/cli/config/core-web.cordis.yml) overlay composes both plugins over the ordinary Web surface, disables its other model-facing consumers, and leaves the Web host, browser, Workspace, persistence, sandbox, and permission stack in place.

The browser keeps its Access picker, answerable approval cards, and risk confirmation for Full access. The TUI gains the existing `/permission` command because the shared Permission service activates its command child there.

# Agent Note: Claude Code and Codex subagent backends
Status: implemented
English | [中文](2026-08-04-claude-code-and-codex-subagent-backends.zh.md)
## Problem
The named [`ctx.subagents`](2026-06-21-subagent-capability-seam.md) registry lets a parent agent delegate work without knowing how the child runs, but the harness needs first-party routes to the real Codex and Claude Code products. Each route must hand the product one self-contained task, let it work in the parent Session's workspace, return a final answer or an explicit failure or cancellation, and leave no managed product process behind.
The product integrations must not become second owners for task text, cwd, cancellation, result settlement, or process trees. Required evidence therefore separates three facts: a keyless real-product test proves the official integration, native authentication shape, deterministic answer, and teardown; a Loader composition test proves that the public package and documented tool configuration load without starting the product; and a credentialed e2e proves that the production provider and real product can obtain a unique answer from the real DeepSeek service. Direct model HTTP or a product double cannot replace either product-running tier, and a hand-mounted plugin cannot replace the Loader tier.
## Decision
The harness publishes two sibling one-shot providers as independently installable, opt-in packages. A user loads a provider and the existing common subagent tool in their own `cordis.yml`: `subagent_codex` binds `codex`, while `subagent_claude_code` binds `claude-code`. The shipped CLI dependency closure and base, Web, and headless configurations load neither provider. Each tool accepts only a standalone text task; product selection and background execution are not model arguments.
Both providers report `inheritsParentContext: false`, advertise no optional start capabilities, and pass the parent Session cwd without copying the parent conversation. Their documented tools disable background execution and use `maxDepth: 'provider-managed'`, leaving recursion policy with the out-of-process product instead of sending a limit the provider cannot enforce. Every call creates a fresh product process and a non-resumable product conversation. The shared subagent service continues to own request resolution, lifecycle events, result settlement, and foreground collection; the shared subprocess service owns credential scrubbing, process-tree termination, and whole-tree exit observation.
```text
fixed tool → shared subagent service → product provider → official product process
← final answer / explicit error / cancellation ← terminal product fact
→ foreground disposal → shared process-tree termination → whole-tree exit
```
### Ownership and lifecycle
| Phase | Shared owner | Product-specific responsibility | Observable result |
| --- | --- | --- | --- |
| Resolve | `dsh-tool-subagent` and `ctx.subagents` | Validate the product's text-only input and derive native startup parameters | Unsupported context or malformed input fails before a run is published |
| Start | `dsh-subprocess` owns every acquired process tree | Reach the smallest native point at which the product conversation and process can both be controlled | `start()` publishes one existing `SubagentRun`, or cleans up and rejects |
| Run | The product owns its native protocol facts; the holder owns their mapping | Submit exactly one task and derive an existing shared stop reason; Codex uses `max-tokens` only for explicit context exhaustion | The parent receives only a final answer or an explicit failure |
| Dispose | The foreground consumer requests release; `dsh-subprocess` proves exit | Close the native protocol and express any best-effort native cancellation | Disposal is idempotent and returns only after the whole process tree exits |
## Codex provider
`@deepseek-ai/dsh-subagent-codex` registers the fixed `codex` provider and starts `codex app-server --stdio` from `PATH`. Its public configuration contains only an explicit `env` overlay and a positive finite `disposeGraceMs` no greater than the repository's shared `MAX_TIMER_DELAY_MS`. Installation, login, `CODEX_HOME`, model selection, base URL, sandbox, approval policy, and product-session settings remain native Codex or deployment responsibilities.
Before publication, the provider validates a non-empty text-only task, starts the managed app-server in the parent workspace, completes `initialize` → `initialized`, and creates an `ephemeral: true` thread. The published run owns exactly one `turn/start`; its thread and turn ids remain private and are never persisted in the parent Session.
`turn/completed` is the authoritative remote terminal fact. The latest `agentMessage` with `phase: "final_answer"` wins, and that selected message must contain nonblank text. When the product emits no explicit final phase, the latest message with `phase: null` is the compatibility fallback and must likewise be nonblank; commentary never replaces either answer. A failed turn with `error.codexErrorInfo: "contextWindowExceeded"` becomes `max-tokens`. A completed turn without an answer, every other failed or interrupted remote turn, malformed required fields in a recognized app-server frame, protocol closure, early process exit, or unknown server request becomes `error`; this version has no native refusal terminal and therefore produces no `refusal`. Local cancellation wins its race and remains `aborted`.
For command and file approvals, the unattended wire selects a non-approval decision offered by the request, preferring `cancel`; the stable 0.146.0 request shape without an offered-decision list falls back to `decline`. It grants no requested permissions for the turn, answers user-input requests with no answers, and declines MCP elicitation. A request with no legal unattended response, or any unknown server request, fails the run instead of waiting for a user interface the provider does not supply.
An unpublished startup failure closes the wire, terminates the acquired process tree, waits for exit, and then rejects `start()`. Published disposal best-effort interrupts a known turn, closes the wire, ends stdin, invokes the shared termination escalation, and waits for whole-tree exit. Result failure and teardown failure stay independently observable.
Codex 0.146.0 speaks the Responses protocol, while DeepSeek's public OpenAI-compatible endpoint speaks Chat Completions. The credentialed Codex e2e therefore uses a loopback-only, test-private bridge for one no-tool nonce request: real Codex sends Responses to the bridge, the bridge forwards the received bearer credential and extracted task to the fixed official DeepSeek endpoint, and it wraps the real text in the minimal Responses SSE lifecycle. The bridge is neither a production proxy nor evidence that Codex connects to DeepSeek Chat Completions natively.
## Claude Code provider
`@deepseek-ai/dsh-subagent-claude-code` registers the fixed `claude-code` provider and invokes `@anthropic-ai/claude-agent-sdk@0.3.220`. The SDK's platform `optionalDependency` supplies the real Claude Code 2.1.220 CLI. The provider uses the official `query()` entrypoint and passes the SDK's `spawnClaudeCodeProcess` command, arguments, cwd, environment, and forwarded signal unchanged to `dsh-subprocess`; its private `SpawnedProcess` adapter exposes only the stream, event, kill, and exit facts the SDK requires.
The public configuration contains the same two deployment-owned values as the Codex sibling: an explicit `env` overlay and a positive finite `disposeGraceMs` no greater than the repository's shared `MAX_TIMER_DELAY_MS`. Each run creates its own `AbortController`, sets `persistSession: false`, and disables `AskUserQuestion`. The provider deliberately omits `settingSources`, so the SDK reads the host's normal user, project, and local Claude settings relative to the parent Session cwd. It neither copies nor filters those settings and does not create or modify login state. It supplies no `canUseTool`, elicitation, or dialog callback, so unattended interactions fail through the SDK rather than waiting for a user interface the provider does not own.
The provider publishes only after both the SDK `Query` and a live managed CLI handle exist. It consumes the complete SDK stream and completes only when a `result` message has `subtype: "success"`, `is_error: false`, and a nonblank `result`, and the iterator then ends normally. Every SDK error subtype, an error-marked success, a missing result, iterator failure, protocol failure, or process failure becomes `error`. SDK turn, budget, and structured-output limits are not token-window facts, and the SDK exposes no native refusal terminal, so this provider produces neither `max-tokens` nor `refusal`. Local cancellation wins and becomes `aborted`.
Startup rollback and published disposal close the SDK query, abort the per-run controller, invoke shared process-tree termination, and wait for whole-tree exit. `Query.close()` expresses graceful protocol intent but does not replace the subprocess owner's exit proof. Query-close failure, process failure, and teardown failure remain independently observable.
The credentialed Claude Code e2e uses the official DeepSeek Claude Code contract directly: the runtime-only DeepSeek key becomes `ANTHROPIC_AUTH_TOKEN`, the fixed official base gains `/anthropic`, and the main and subagent model variables select the documented DeepSeek models. It starts the production provider and real SDK/CLI, requires one random nonce as the complete answer, persists no credential in settings, and waits for every managed handle to exit.
## Distribution and evidence
Each product owns branch-complete package tests, a required keyless real-product spec, a Loader composition e2e, and a credentialed DeepSeek e2e. The keyless product tier uses the exact official distribution under test, a non-empty fake product key, an isolated temporary workspace and product home, and a loopback fixed-answer model. Missing product requests, wrong authentication, altered task text, a non-exact answer, a skipped real product, or a surviving managed handle fails the required test. The Loader tier boots the README-shaped user configuration, verifies both fixed foreground-only tools in one context, and starts neither product process. The credentialed tier starts the same production provider and real product with a runtime-only key, requires a unique nonce from the fixed official DeepSeek service, and proves quiescence again; it self-skips only when a local operator supplied no key, while trusted CI preflights the secret.
The Codex evidence pins `@openai/codex@0.146.0` and `codex-cli 0.146.0`. Its real-product spec observes the exact Bearer key, original task, byte-exact final answer, unattended command rejection with no file side effect, local cancellation, and whole-tree exit. Production still supplies `codex` on `PATH`.
The Codex credentialed e2e registers the production provider, starts the same real app-server, and requests one random nonce through the test-private bridge described above. It fixes the external endpoint and model, stores no credential or request payload, requires exactly one completed upstream response, compares the trimmed product answer byte-for-byte with the nonce, and waits for every managed handle to exit.
The Claude Code evidence pins Agent SDK 0.3.220 and its platform-distributed Claude Code 2.1.220 CLI. Its real-product spec observes the exact `x-api-key`, original task, byte-exact final answer, inherited temporary host-setting marker, process failure, local cancellation, and whole-tree exit. The Loader e2e resolves both product packages by name while neither product command is available and records zero child starts.
The Claude Code credentialed e2e maps the key and fixed official endpoint only in the provider's in-memory environment, uses the documented `deepseek-v4-pro[1m]` and `deepseek-v4-flash` model variables, and traverses the production provider, official SDK, and real CLI. It compares the trimmed result with a random nonce and proves whole-tree exit without calling the Messages API directly from the test.
The project owner's distribution authorization is scoped to the official `@anthropic-ai/claude-agent-sdk` identity and the official Claude Code CLI/platform payloads each SDK version declares through `optionalDependencies`. [`THIRD_PARTY_NOTICES.md`](../../../../THIRD_PARTY_NOTICES.md) derives and discloses the current payload set without reclassifying its declared terms as permissive. Version, license-field, and payload-set changes still undergo ordinary dependency, lockfile, compatibility, terms, and notices review; unrelated non-permissive runtime packages continue to fail closed.
## Alternatives considered
**Direct model HTTP, `codex exec`, or a hand-written Claude CLI protocol.** These paths bypass the products' official extensible integration surfaces and cannot prove native configuration, tools, approvals, result semantics, or teardown. Each provider uses its official product integration instead.
**A shared product-process helper package.** The existing subagent and subprocess seams already own every shared task, result, environment, and process-tree concern. A new helper would duplicate ownership without deleting either private product adapter, so each adapter calls the existing seams directly.
**A model-visible product selector.** Product availability and authentication are deployment facts. Two fixed tools keep each schema and provider binding explicit and avoid adding dynamic selection state to the common service.
**Product doubles as required evidence.** Doubles cover exhaustive private protocol branches but do not prove package exports, official distributions, authentication, or real process behavior. Required evidence drives each official product against a loopback model fixture.
**Plugin-managed login, product home, models, settings, or permissions.** Those choices would create another authority beside each product's native configuration and enlarge a one-shot provider into account management. The providers expose only an explicit environment overlay and teardown grace; unattended interaction fails closed.
**Continuation, progress, background collection, and shared parent context.** The delivered user result is one self-contained task and one final answer. Product sessions, resume, follow-up, intermediate messages, parent transcript transfer, structured output, and background collection need separate user contracts and are not prebuilt.
## Consequences
Users can install either or both product providers, bind stable foreground tools in their own Cordis configuration, and delegate one self-contained task through the existing subagent contract. Official product integrations preserve native settings and behavior while shared services retain the sole ownership of task settlement and process-tree quiescence.
Every delegation pays for a fresh product process and independent model context, and only final text reaches the parent. Product-native configuration makes behavior depend on the deployment's installed product, account state, and workspace settings. Credentialed e2e runs also spend external API quota and depend on the official DeepSeek endpoint; deterministic protocol, failure, cancellation, and approval coverage remains in the keyless tier. The providers do not resume sessions, stream progress, accept new human interaction, roll back tool or file side effects, or impose a wall-clock timeout.
Compatibility is pinned by package-level unit coverage, keyless real-product loopback tests, credentialed DeepSeek nonce tests, public Loader composition, built-package and NodeNext consumer checks, generated documentation and notices, and the repository CI matrix. A supported product or DeepSeek endpoint/model baseline change must refresh those facts; production performs no separate runtime version probe.

命名的 [`ctx.subagents`](2026-06-21-subagent-capability-seam.md) 注册表让父 agent(智能体)无需了解子级的运行方式即可委派工作,但 harness 需要通往真实 Codex 与 Claude Code 产品的第一方路径。每条路径都必须向产品交付一项自包含任务,让它在父会话的工作区中执行,返回最终回答或明确的失败或取消结果,并且不留下任何受管的产品进程。
产品集成不得成为任务文本、cwd、取消、结果结算或进程树的第二责任方。因此,所需证据要区分三个事实:无密钥真实产品测试证明官方集成、原生身份验证形态、确定性答案与资源清理;Loader 组合测试证明公开包(package)和文档所示的工具配置无需启动产品即可加载;带密钥 e2e 证明生产提供方与真实产品能够从真实 DeepSeek 服务取得唯一答案。直接发起模型 HTTP 请求或使用产品替身无法取代上述任一产品运行层级;手工挂载插件无法取代 Loader 层级。
## 决策
harness 将两个一次性兄弟提供方作为可独立安装、选择启用的包交付。用户在自己的 `cordis.yml` 中加载提供方与现有的通用 subagent 工具:`subagent_codex` 绑定 `codex`,`subagent_claude_code` 绑定 `claude-code`。随产品交付的 CLI(命令行界面)依赖闭包,以及基础、Web 与 headless 配置都不会加载任一提供方。每个工具只接受独立文本任务;产品选择与后台执行都不作为模型参数。
这两个提供方都报告 `inheritsParentContext: false`,不声明任何可选的启动能力,并传递父会话 cwd,但不会复制父级对话。文档所示的工具会禁用后台执行,并使用 `maxDepth: 'provider-managed'`,将递归策略留给进程外产品,而不是发送提供方无法强制执行的限制。每次调用都会创建一个全新的产品进程和一次不可续接的产品对话。共享 subagent 服务继续负责请求解析、生命周期事件、结果结算和前台收集;共享子进程服务负责凭证清洗、进程树终止以及整棵进程树的退出观测。

### 归属与生命周期
| 阶段 | 共享责任方 | 产品特定职责 | 可观察结果 |
| --- | --- | --- | --- |
| 解析 | `dsh-tool-subagent` 与 `ctx.subagents` | 验证产品的纯文本输入并推导原生启动参数 | 不受支持的上下文或格式错误的输入会在发布运行前报错 |
| 启动 | `dsh-subprocess` 负责每棵已获取的进程树 | 到达能够同时控制产品对话与进程的最小原生控制点 | `start()` 发布一个已存在的 `SubagentRun`,否则清理后拒绝调用 |
| 运行 | 产品负责其原生协议事实;持有方负责映射这些事实 | 只提交一项任务,并推导出一种现有的共享停止原因;Codex 仅在明确发生上下文耗尽时使用 `max-tokens` | 父级只会收到最终回答或明确失败 |
| dispose(资源释放) | 前台消费方请求释放;`dsh-subprocess` 证明进程已退出 | 关闭原生协议,并发出尽力而为的原生取消请求 | 释放操作具有幂等性,且仅在整棵进程树退出后才返回 |
## Codex 提供方
`@deepseek-ai/dsh-subagent-codex` 注册固定的 `codex` 提供方,并启动 `codex app-server --stdio`,该命令从 `PATH` 解析。其公开配置仅包含显式的 `env` 覆盖项和须为正有限值的 `disposeGraceMs`,且后者不得大于仓库共享的 `MAX_TIMER_DELAY_MS`。安装、登录、`CODEX_HOME`、模型选择、基础 URL、沙箱、审批策略和产品会话设置仍由 Codex 原生机制或部署环境负责。
发布前,提供方会验证非空的纯文本任务,在父级工作区中启动受管的 app-server,完成 `initialize` → `initialized` 握手,并创建一个 `ephemeral: true` 线程。已发布的运行只拥有一次 `turn/start`;其线程 ID 与轮次 ID 保持私有,绝不会持久化到父会话。
`turn/completed` 是权威的远端终止事实。以最后一条带有 `phase: "final_answer"` 的 `agentMessage` 为准,且选中的消息必须包含非空白文本。若产品没有发出明确的最终阶段,则以最后一条 `phase: null` 的消息作为兼容性回退,该消息也必须包含非空白文本;过程说明绝不会取代上述任一答案。带有 `error.codexErrorInfo: "contextWindowExceeded"` 的失败轮次会成为 `max-tokens`。轮次完成却没有答案、其他任何远端失败或中断轮次、已识别的 app-server 帧中必需字段格式错误、协议关闭、进程提前退出或未知的服务器请求,都会产生 `error`;本版本没有原生的拒绝终止状态,因此不会产生 `refusal`。本地取消在竞态中胜出并保持为 `aborted`。
对于命令与文件审批,无人值守的协议连接会从请求给出的决策选项中选择一项不予批准的决策,并优先选择 `cancel`;稳定的 0.146.0 请求形态没有决策选项列表,因此回退到 `decline`。它不授予该轮次请求的任何权限,不向用户输入请求提供任何答案,并拒绝 MCP elicitation。若请求在无人值守模式下没有合法响应,或是未知服务器请求,此次运行就会失败,而不会等待本提供方没有提供的用户界面。
若启动在发布前失败,提供方会关闭协议连接、终止已获取的进程树并等待其退出,然后拒绝 `start()`。对已发布的运行执行资源释放时,提供方会尽力中断已知轮次、关闭协议连接、结束标准输入、调用共享的逐级终止机制,并等待整棵进程树退出。结果失败与清理失败仍可彼此独立地观察。
Codex 0.146.0 使用 Responses 协议,而 DeepSeek 的公开 OpenAI 兼容端点使用 Chat Completions。因此,带密钥 Codex e2e 会采用一个仅限回环、仅供测试内部使用的桥接层来处理一次不使用工具的随机数请求:真实 Codex 将 Responses 发送到桥接层,桥接层把收到的 Bearer 凭据与提取出的任务转发到固定的 DeepSeek 官方端点,再将真实文本包装进最小化的 Responses SSE(Server-Sent Events)生命周期。该桥接层既不是生产代理,也不能作为 Codex 原生连接 DeepSeek Chat Completions 的证据。
## Claude Code 提供方
`@deepseek-ai/dsh-subagent-claude-code` 注册固定的 `claude-code` 提供方,并调用 `@anthropic-ai/claude-agent-sdk@0.3.220`。SDK 的平台 `optionalDependency` 提供真实的 Claude Code 2.1.220 CLI。提供方使用官方 `query()` 入口点,并将 SDK 的 `spawnClaudeCodeProcess` 命令、参数、cwd、环境和转发的信号原样传入 `dsh-subprocess`;其私有 `SpawnedProcess` 适配器只公开 SDK 所需的流、事件、终止和退出事实。
公开配置包含与 Codex 兄弟提供方相同、由部署方负责的两个值:显式的 `env` 覆盖项,以及须为正有限值且不得大于仓库共享 `MAX_TIMER_DELAY_MS` 的 `disposeGraceMs`。每次运行都会创建自己的 `AbortController`,设置 `persistSession: false` 并禁用 `AskUserQuestion`。提供方故意省略 `settingSources`,因此 SDK 会相对于父会话 cwd 读取宿主机常规的用户、项目和本地 Claude 设置。它既不复制也不过滤这些设置,也不会创建或修改登录状态。提供方不设置 `canUseTool`、elicitation 或对话回调,因此无人值守交互会经 SDK 失败,而不会等待本提供方不负责的用户界面。
只有在 SDK `Query` 与受管的活动 CLI 句柄都已存在后,提供方才会发布运行。它会消费完整的 SDK 流;只有 `result` 消息具有 `subtype: "success"`、`is_error: false` 和非空白 `result`,且迭代器随后正常结束时,运行才会完成。所有 SDK 错误子类型、标记为错误的成功消息、结果缺失、迭代器失败、协议失败或进程失败都会成为 `error`。SDK 的轮次、预算和结构化输出限制不表示 token 窗口耗尽,而且 SDK 没有原生的拒绝终止状态,因此本提供方不会产生 `max-tokens` 或 `refusal`。本地取消会胜出并成为 `aborted`。
启动回滚和已发布运行的资源释放都会关闭 SDK query、中止该次运行的控制器、调用共享的进程树终止机制,并等待整棵进程树退出。`Query.close()` 表达优雅的协议关闭意图,但不能取代子进程责任方的退出证明。Query 关闭失败、进程失败和清理失败仍可彼此独立地观察。
带密钥 Claude Code e2e 直接使用官方 DeepSeek Claude Code 契约:仅在运行时提供的 DeepSeek 密钥会映射为 `ANTHROPIC_AUTH_TOKEN`,固定的官方基础 URL 会追加 `/anthropic`,主模型与 subagent 模型变量会选择文档所示的 DeepSeek 模型。该测试会启动生产提供方与真实 SDK 和 CLI,要求一个随机数作为完整答案,不会把任何凭据持久化到设置中,并等待所有受管句柄退出。
## 分发与证据
每个产品都负责覆盖所有分支的包测试、一项必跑的无密钥真实产品测试、一项 Loader 组合 e2e 和一项带密钥 DeepSeek e2e。无密钥产品层级使用被测的确切官方发行版、非空的伪产品密钥、隔离的临时工作区与产品主目录,以及能返回固定答案的回环模型。产品请求缺失、身份验证错误、任务文本被改动、答案不完全一致、真实产品被跳过或受管句柄仍存活,都会使这项必跑测试失败。Loader 层级会启动 README 所示形态的用户配置,在同一个上下文中验证两个固定且只支持前台执行的工具,并且不会启动任何产品进程。带密钥层级会使用仅在运行时提供的密钥启动同一生产提供方与真实产品,要求从固定的 DeepSeek 官方服务取得唯一随机数,并再次证明完全停稳;仅当本地操作者未提供密钥时才会自行跳过,而受信任的 CI 会预检该 secret。
Codex 证据锁定 `@openai/codex@0.146.0` 与 `codex-cli 0.146.0`。其真实产品测试会观测确切的 Bearer 密钥、原始任务、逐字节完全一致的最终回答、不会产生文件副作用的无人值守命令拒绝、本地取消以及整棵进程树退出。生产环境仍提供 `codex`,并通过 `PATH` 解析。
带密钥 Codex e2e 会注册生产提供方,启动同样的真实 app-server,并通过上述测试专用桥接层请求一个随机数。该测试固定外部端点与模型,不存储任何凭据或请求载荷,要求上游恰好完成一次响应,将去除首尾空白后的产品答案与该随机数逐字节比较,并等待所有受管句柄退出。
Claude Code 证据锁定 Agent SDK 0.3.220 及其平台分发的 Claude Code 2.1.220 CLI。其真实产品测试会观测确切的 `x-api-key`、原始任务、逐字节完全一致的最终回答、继承的临时宿主设置标记、进程失败、本地取消以及整棵进程树退出。Loader e2e 会在两个产品命令均不可用时按名称解析两个产品包,并记录零次子级启动。
带密钥 Claude Code e2e 仅在提供方的内存环境中映射密钥与固定的官方端点,把模型变量设为文档所示的 `deepseek-v4-pro[1m]` 与 `deepseek-v4-flash`,并实际经过生产提供方、官方 SDK 与真实 CLI。它将去除首尾空白后的结果与一个随机数比较,并证明整棵进程树退出,且测试不会直接调用 Messages API。
项目所有者的分发授权范围限定为官方 `@anthropic-ai/claude-agent-sdk` 身份,以及每个 SDK 版本通过 `optionalDependencies` 声明的官方 Claude Code CLI 与平台载荷。[`THIRD_PARTY_NOTICES.md`](../../../../THIRD_PARTY_NOTICES.md) 会推导并披露当前载荷集合,但不会将其声明条款重新归类为宽松条款。版本、许可证字段和载荷集合发生变化时,仍须经过常规的依赖、锁文件、兼容性、条款和声明评审;无关的非宽松运行时包继续以默认拒绝方式失败。
## 曾考虑的替代方案
**直接模型 HTTP、`codex exec` 或手写的 Claude CLI 协议。** 这些路径会绕过产品的官方可扩展集成接口,无法证明原生配置、工具、审批、结果语义或资源清理。每个提供方都改用相应的官方产品集成。
**共享产品进程辅助包。** 现有 subagent 与子进程 seam 已负责围绕任务、结果、环境和进程树的全部共享职责。新辅助包无法删除任一私有产品适配器,只会造成责任重复,因此每个适配器都会直接调用现有 seam。
**面向模型的产品选择器。** 产品可用性和身份验证属于部署事实。两个固定工具使各自的 schema 与提供方绑定保持明确,也避免在通用服务中添加动态选择状态。
**以产品替身作为强制证据。** 替身可以穷尽覆盖私有协议分支,但无法证明包导出、官方发行版、身份验证或真实进程行为。强制证据会驱动每个官方产品连接回环模型 fixture(测试前置数据)。
**由插件管理登录、产品主目录、模型、设置或权限。** 这些选择会在每个产品的原生配置之外建立另一套权威来源,并将一次性提供方扩张为账户管理功能。提供方只公开显式环境覆盖项和清理宽限期;无人值守交互会以默认拒绝方式失败。
**续接、进度、后台收集和共享父级上下文。** 已交付的用户结果是一项自包含任务和一个最终回答。产品会话、恢复、后续交互、中间消息、父级 transcript(文本记录)传递、结构化输出和后台收集都需要独立的用户契约,当前实现不会预先构建这些功能。
## 后果
用户可以安装任一或两个产品提供方,在自己的 Cordis 配置中绑定稳定的前台工具,并通过现有 subagent 契约委派一项自包含任务。官方产品集成会保留原生设置与行为,而共享服务继续独占任务结算与进程树完全停稳的责任。
每次委派都要承担新建产品进程和独立模型上下文的开销,且只有最终文本会到达父级。产品原生配置使行为取决于部署环境中安装的产品、账户状态和工作区设置。带密钥 e2e 运行还会消耗外部 API 配额,并依赖 DeepSeek 官方端点;对协议、失败、取消与审批的确定性覆盖仍由无密钥层级承担。提供方不会恢复会话、以流式方式传送进度、接受新的人工交互、回滚工具或文件副作用,也不会施加按实际经过时间触发的超时。
兼容性由包级单元测试覆盖率、无密钥真实产品回环测试、带密钥 DeepSeek 随机数测试、公开 Loader 组合、已构建包与 NodeNext 消费方检查、生成的文档与声明以及仓库 CI 矩阵共同锁定。更改受支持的产品基线或 DeepSeek 端点/模型基线时必须刷新这些事实;生产环境不会另行执行运行时版本探测。
