截至 2026-10-09, 新 Codex Cloud 可从 web、mobile、desktop 使用。web / desktop 在 Work in → Cloud 选择已发布环境, mobile 在 Codex 中选择。环境保存仓库、依赖、工具与访问设置, 每个新任务得到独立工作区。先在 web / desktop 创建环境、检查准备报告和测试, 再 Publish;保存草稿与发布可复用环境不是同一步。1注 1Note 1OpenAI · Cloud environments。新环境的准备、发布、隔离工作区和 secrets;截至 2026-10-09。OpenAI · Cloud environments.

Web / desktop select a published environment under Work in → Cloud; mobile selects one in Codex.

提示词PromptCodex Cloud · Setup
为 <个人项目> 准备云端环境。先读取锁文件和说明, 报告需要的运行时、安装命令和测试命令。只安装项目已有依赖, 不修改业务文件。缺权限或密钥时停下来, 不把凭据写入代码或日志。测试完成后给我准备报告, 等我检查再发布环境。Prepare a cloud environment for <personal project>. Read lockfiles and instructions; identify runtime, installation, and test commands. Install only existing project dependencies and do not change application files. Stop for missing access or secrets; never write credentials into code or logs. Return a setup report for review before environment publication.
为我的 Node.js 文件名预览工具准备环境。先检查 package.json 与锁文件, 确认 node --test 能运行。没有依赖时不要新增包。测试只能使用合成文件名, 不连接网盘、不上传私人目录。报告运行时版本、执行命令、结果和未完成事项, 等我确认再 Publish。Prepare my Node.js filename-preview utility. Check package.json and lockfiles and confirm node --test runs. Add no packages if it has no dependencies. Test synthetic names only; do not connect cloud storage or upload private folders. Report runtime, commands, results, and unfinished work; wait for confirmation before Publish.
新任务使用已发布的准备状态;已有任务保留自己的文件状态。更新环境后 Republish, 再开新任务验证, 不假定旧任务自动获得新依赖。保存的云端状态也不能替代源码版本管理:验收后保存重要文件或提交你确认的改动。账号未出现 Cloud 时, 先留在本地, 不借不存在的入口绕过限制。New tasks use the published setup; existing tasks retain their own files. Republish changes and verify in a new task instead of assuming existing tasks receive new dependencies. Saved cloud state is not source control: save important outputs or commit reviewed changes. If Cloud is not available to your account, stay local rather than inventing a workaround.凭据要区分直接环境变量与 network secret。前者程序可以直接读到;后者对允许的 HTTPS 目标通过代理替换占位值。不要把代理保护理解成所有秘密都不可见, 也不要把放行域名当成服务授权。创建环境、私人仓库与网络策略在本轮没有真实账号实测, 属于待核入口。Distinguish direct environment variables from network secrets. Programs can read the former; the latter use proxy substitution for allowed HTTPS destinations. Do not infer that every secret is hidden or that an allowed domain grants service authorization. Environment creation, private-repository access, and network policies remain untested on a live account in this edition.
#Legacy:认清自己看的是哪套文档Legacy: Identify the Documentation You Are Using.
旧 Cloud Legacy 仍支持 Code Review、Linear 和 GitHub 集成, 官方计划弃用, 但不能据此编一个下线日期。它的 setup / maintenance scripts、缓存与 secrets 生命周期需要按 Legacy 文档看:旧 secrets 只供 setup, agent 阶段前移除。这个结论不能复制到新 Cloud 的 network secret。2注 2Note 2OpenAI · Codex Cloud (Legacy)。旧集成的 setup、maintenance、secret 生命周期与新 Cloud 分开;截至 2026-10-09。OpenAI · Codex Cloud (Legacy).

工具连接与引擎嵌入, 分开理解Separate Tool Connections from Engine Embedding.
MCP server 提供工具或资料, Codex 作为 client 调用它。STDIO 在本机启动进程;Streamable HTTP 连接一个服务地址。先选任务所需的最小连接, 别把陌生 server 当成「安装就可信」。下面连接官方开发者资料源, 会修改你的 MCP 配置;只在你确实需要时执行。3注 3Note 3OpenAI · Model Context Protocol。Codex 作为 MCP client 的 STDIO / Streamable HTTP 配置;截至 2026-10-09。OpenAI · Model Context Protocol.

需要 OAuth 的服务再走对应 login, 密钥用服务支持的环境变量/认证流程, 不粘进书里、仓库或聊天记录。启动客户端后检查 /mcp, 再做一次只读查询。注册成功不等于查询成功;失败先区分进程没启动、地址不可达、未认证和工具不可用。连接停用也不替你撤销第三方账号里的授权, 不再需要时两处都检查。For OAuth services, follow their login flow; use supported environment or authentication mechanisms for secrets, not book text, repositories, or chat transcripts. Check /mcp after starting the client and run one read-only query. Registration is not a successful query: distinguish startup, reachability, authentication, and tool availability. Disabling a connection does not revoke the third-party account grant; inspect both when finished.
#旧 MCP server 路线迁到 App ServerMigrate the Old MCP-Server Route to App Server.
旧稿的另一种方向是「把 Codex 自己暴露成 MCP server, 供外层 agent 调用」。截至 2026-10-09, 官方已经移除 codex mcp-server 和独立二进制, 推荐 App Server。4注 4Note 4OpenAI · Developer commands / App Server。旧 mcp-server 已移除, 当前嵌入入口为 app-server;截至 2026-10-09。OpenAI · Developer commands / App Server.

第二条启动等待协议消息的进程, 不是聊天界面。App Server 使用 JSON-RPC:客户端先发 initialize, 收到回应后发 initialized, 再 thread/start 与 turn/start, 并处理事件和审批请求。10注 10Note 10OpenAI · Codex App Server。JSON-RPC 初始化、线程与轮次生命周期;截至 2026-10-09。OpenAI · Codex App Server.

App Server uses JSON-RPC: initialize, receive the response, send initialized, then start a thread and turn while handling events and approvals.10注 10Note 10OpenAI · Codex App Server。JSON-RPC 初始化、线程与轮次生命周期;截至 2026-10-09。OpenAI · Codex App Server.

一次性脚本与 SDKOne-Shot Scripts and SDKs.
#exec:只读调查, 结构化交付exec: Read-Only Inspection with Structured Output.
脚本里用 codex exec, 不需要模拟人敲界面。--json 是事件流, --output-schema 限制最终响应的结构, -o 保存最终消息;结构正确不保证事实正确。5注 5Note 5OpenAI · Non-interactive mode。exec、JSONL、结构化输出与无人值守限制;截至 2026-10-09。OpenAI · Non-interactive mode. exec, JSONL, structured output, and unattended constraints; checked 2026-10-09.本机 0.160.1 支持这些 flag。不要依赖默认权限:脚本把只读与不弹审批显式写出来, 遇阻停止而非放权。Use codex exec instead of simulating UI keystrokes. --json emits events, --output-schema constrains final response shape, and -o saves the final message. Valid structure does not prove correct facts.5注 5Note 5OpenAI · Non-interactive mode。exec、JSONL、结构化输出与无人值守限制;截至 2026-10-09。OpenAI · Non-interactive mode. exec, JSONL, structured output, and unattended constraints; checked 2026-10-09. Local 0.160.1 supports these flags. Set read-only and no-approval behavior explicitly so blocked work fails rather than expanding access.将 triage.schema.json 保存到练习仓库后运行。命令会产生模型用量并把结果写入 triage.json, 运行前检查该输出文件不存在或可以替换。Save triage.schema.json in the practice repository. The command uses model quota and writes triage.json; verify that output does not exist or may be replaced before running.
codex exec --sandbox read-only --ask-for-approval never \ --output-schema triage.schema.json -o triage.json \ "Read collision-key.mjs and its tests. List untested behavior with file evidence. Do not modify files, install packages, or use external services."
自动处理结果的脚本必须同时检查进程退出码、JSON schema 和业务字段。返回 unverified 时不要当成通过。需要审计过程再增加 --json, 但事件日志可能含路径与资料, 保存前考虑隐私。长期任务保留具体 thread id, 避免无人值守时用含糊的 resume --last 续到错误会话。A consumer script must check exit status, JSON shape, and business fields. Treat unverified as unverified, not success. Add --json for process auditing, considering sensitive paths and data in logs. Save an explicit thread ID for recurring workflows instead of resuming an ambiguous latest session unattended.
#SDK:把重复调用包进程序SDK: Put Repeated Calls into a Program.
先在单独的练习项目安装 @openai/codex-sdk, 再把下例保存为 inspect.mjs, 用 node inspect.mjs 运行。调用会使用账号或 API 凭据对应的用量, 不能因它是 JavaScript 就当免费。示例按官方 SDK 用法与 TypeScript 仓库配置接口核对, 未在本轮运行模型。6注 6Note 6OpenAI · Codex SDK。TypeScript / Python SDK 用法;配置覆盖另与官方 TypeScript 仓库 README 核对;截至 2026-10-09。OpenAI · Codex SDK.

import { Codex } from "@openai/codex-sdk";const codex = new Codex({ config: { sandbox_mode: "read-only", approval_policy: "never", },});const thread = codex.startThread();const result = await thread.run( "Inspect the collision-key tests. Report missing cases with file evidence. Do not edit or access external services.");console.log(result.finalResponse);console.log("Thread:", thread.id);
同一 thread 再 run 可继续;跨进程保存 id 后用 resumeThread(id)。Python 的 openai-codex 使用 app-server, 有 Codex / AsyncCodex 与 Sandbox 预设。选一种语言即可。给生产程序加超时、重试上限、失败记录和人工接手路径;不把一段成功示例直接变成永不停止的循环。Call run again on the same thread to continue, or persist its ID and use resumeThread(id) across processes. Python's openai-codex uses app-server with Codex / AsyncCodex and Sandbox presets. Choose one language. Add timeouts, bounded retries, failure records, and human takeover before production use; one successful sample is not an endless-loop design.

CI 与 hooks:先让一次检查可靠CI and Hooks: Make One Check Reliable First.
#CI 用可信手动触发开始Start CI with a Trusted Manual Trigger.
GitHub Action 可在隔离 runner 里运行 Codex。本例只允许维护者手动发起、只读仓库、不自动评论或推送。先在仓库 secrets 配好 API key, 明白它走独立 API 账单, 再启用。正式使用前将 Action 版本固定到审核过的提交 SHA;下面保留易读版本名作为教学示例。7注 7Note 7OpenAI · Codex GitHub Action。可信触发、最小权限、drop-sudo 和 secrets 边界;截至 2026-10-09。OpenAI · Codex GitHub Action.

不要把不受信 PR 正文直接拼成高权限指令, 不用 pull_request_target 给陌生代码送密钥。read-only 不是秘密保护的全部;保留 drop-sudo、最小环境变量与可信触发, 不自动加载未经审阅的项目 hook。模型检查是补充, 确定性测试仍独立运行, 未验证结论不能自动合并。Do not turn untrusted PR text into privileged instructions or use pull_request_target to expose secrets to unfamiliar code. Read-only is not complete secret protection: retain drop-sudo, minimal environment variables, and trusted triggers, and avoid unreviewed project hooks. Model review supplements deterministic tests; unverified conclusions must not auto-merge changes.
#Stop hook:失败一次, 不无限返工Stop Hook: One Retry, Not Endless Rework.
hooks 可以在工具前后、输入或结束时运行脚本。当前从用户与受信项目的 hooks.json 或 config.toml 加载, 多个来源会合并。非托管 hook 需在 /hooks 中审阅并信任当前定义的哈希, 改动后重新审。Stop 成功退出时必须输出 JSON;普通文本无效。8注 8Note 8OpenAI · Hooks。hook 来源、信任哈希、Stop 的 JSON 输出与防循环字段;截至 2026-10-09。OpenAI · Hooks.

They run only the previous appendix's collision-key.test.mjs, not arbitrary project checks. Failure requests one bounded continuation; if stop_hook_active indicates a prior continuation, the script stops for human review instead of repeatedly consuming usage.验证要看两层:脚本收到测试事件后能输出正确 JSON;真实客户端确实加载、信任并执行 hook。本轮只验证了脚本成功、失败与防循环分支, 未完成客户端信任与触发实测。不要为了省去审阅启用 bypass-hook-trust, 也不要把钩子配置存在当成它已经运行。Verify two layers: the script emits correct JSON for test events, and the actual client loads, trusts, and executes it. This edition checks script success, failure, and loop prevention, not the client's trust and event flow. Do not bypass hook trust to skip review or assume a configured hook has run.

验收:把结果收回来Review: Bring the Result Back.
#diff、运行证据与人工试用Diff, Execution Evidence, and Hands-On Checks.
先核对任务目标和修改范围, 再看 diff、实际运行的测试、失败项和没验证的部分。桌面可用的行内 diff 编辑与侧栏 PR review 便于逐处讨论;入口随客户端与设置不同, 缺少这些控件时用 git diff 与普通审查对话。任何界面都不能替你发现缺失的测试标准。Check the goal and scope, then inspect the diff, tests actually run, failures, and unverified areas. Available desktop inline diff editing and sidebar PR review help discuss individual changes; controls vary by client and settings. Use git diff and a review chat when unavailable. No interface supplies missing acceptance criteria for you.连接 GitHub 并启用仓库 Code Review 后, PR 评论里的 @codex review 可请求审查。当前 GitHub review 重点标出 P0 / P1;没有评论不代表不存在较低级问题。用最近的 AGENTS.md 中的 review rules 说明业务风险, 而把格式检查留给 CI。9注 9Note 9OpenAI · Review GitHub pull requests with Codex。GitHub 审查设置、@codex review 与 P0 / P1 范围;截至 2026-10-09。OpenAI · Review GitHub pull requests with Codex.

Rerun the same cases after model upgrades, skill edits, or tool additions. Keep tests, sources, execution records, and deliverables together to distinguish improvement from a lucky run.
离开电脑以后, 边界和验收仍然需要有人负责.
