Summary

Adds an opt-in setting to replace external CLI Harnesses' global user instruction files with Codex's global user custom instructions ($CODEX_HOME/AGENTS.override.md or $CODEX_HOME/AGENTS.md), with per-CLI toggles and automatic backup/restore of original files:

  • Shared Contracts (@codexhost/shared-contracts):
    • Adds codexhost/harness/user-instructions-settings/get and codexhost/harness/user-instructions-settings/set RPC methods and Zod schemas (harnessUserInstructionsSettingsSchema, harnessUserInstructionsSetSchema).
    • Exposes both methods to the local Web Console in CONSOLE_HOST_METHODS.
  • Host Runtime (@codexhost/host-runtime):
    • Adds HarnessUserInstructionsStore in packages/host-runtime/src/harness-user-instructions.ts:
      • Persists settings (enabled, disabledHarnesses) at <CODEXHOST_DATA_DIR || ~/.codexhost>/harness-user-instructions-settings-v1.json (defaulting to enabled: false).
      • Reads Codex global user instructions from $CODEX_HOME/AGENTS.override.md (when present and non-empty) or $CODEX_HOME/AGENTS.md.
      • Before replacing an external CLI's global user instruction file (~/.claude/CLAUDE.md, ~/.gemini/GEMINI.md, ~/.qwen/QWEN.md, ~/.config/opencode/AGENTS.md, ~/.pi/agent/AGENTS.md, ~/.omp/agent/AGENTS.md, ~/.kimi-code/AGENTS.md, ~/.codebuddy/CODEBUDDY.md, ~/.workbuddy-ai/WORKBUDDY.md, ~/.qoder/AGENTS.md, ~/.qoder-cn/AGENTS.md, ~/.copilot/copilot-instructions.md, ~/.cursor/AGENTS.md, ~/.kiro/steering/AGENTS.md, ~/.hermes/AGENTS.md, ~/.zcode/AGENTS.md, ~/.deepseek/AGENTS.md, ~/.grok/AGENTS.md, ~/.devin/AGENTS.md), records a backup manifest under <CODEXHOST_DATA_DIR || ~/.codexhost>/user-instructions-backups/<harnessId>.json.
      • Only syncs installed CLIs whose config root directory exists during global sync() (avoiding stray dot-folders in ~), while syncHarness(harnessId) ensures the directory exists when opening or resuming a session for that CLI.
      • Restores the backed-up original file (or deletes the managed file if no original existed) when disabled globally or per-CLI.
  • Renderer Settings (@codexhost/renderer-extension):
    • Mounts the User instructions (用户自定义指令) section on the Preferences (appearance) page with a master switch and per-CLI switches (user-instructions-controls.ts), localized in English and Simplified Chinese.

Summary

Summary by CodeRabbit

  • 新功能
    • 新增用户指令同步设置,可启用或停用同步,并分别控制各外部 CLI。
    • 启用后,可将 Codex 用户指令同步至已启用的外部 CLI;停用时,若目标文件未被修改,则恢复原内容或移除原先不存在的文件。
    • 设置页面提供指令来源说明、加载状态及错误提示。
    • 创建或恢复外部会话时会同步对应指令;同步失败会记录诊断信息,但不会阻止会话继续打开或恢复。

新增设置接口和界面,用于将 Codex 用户指令同步到外部 Harness。Host Runtime 在会话打开或恢复前触发对应 Harness 的同步,也会在启动时执行批量同步。

Changes: 用户指令同步

Layer / File(s) Summary
设置契约与指令文件同步
packages/shared-contracts/src/harness-user-instructions-settings.ts, packages/shared-contracts/src/index.ts, packages/host-runtime/src/harness-user-instructions.ts, packages/host-runtime/src/index.ts
新增设置请求和响应 schema。存储实现解析外部 Harness 目标,并优先选择非空的 AGENTS.override.md,否则选择 AGENTS.md。启用时备份原指令文件并写入 Codex 指令;停用时根据文件摘要恢复原文件,或删除此前不存在的文件。
Host RPC 与会话同步
packages/shared-contracts/src/console.ts, packages/host-runtime/src/app-server-host.ts, packages/host-runtime/src/desktop-control-requests.ts, packages/host-runtime/src/external-thread-runtime.ts, packages/host-runtime/src/run-host-runtime.ts, packages/host-runtime/test/harness-user-instructions.test.ts
Host 新增设置读取和写入 RPC。参数无效时返回 -32602,操作异常时返回 -32000。Host 在外部会话打开或恢复前触发同步;启动同步失败时记录错误,其他同步失败时继续原有流程。测试覆盖设置、文件恢复、RPC 结果和参数验证。
Renderer 设置控件与客户端
packages/renderer-extension/src/renderer-model-client.ts, packages/renderer-extension/src/settings/loaded-sessions-table.ts, packages/renderer-extension/src/settings/appearance-page.ts, packages/renderer-extension/src/settings/user-instructions-controls.ts, packages/renderer-extension/src/settings/localization.ts, packages/renderer-extension/test/renderer-model-client.test.ts, packages/renderer-extension/test/settings/user-instructions-controls.test.ts
客户端新增设置 RPC 方法。设置页新增全局开关和各 Harness 开关,并显示同步状态。英文和简体中文消息对象新增对应文案;测试覆盖控件加载、开关更新和客户端公开方法。

Explanation

[#740] 的设置存储、默认关闭、源文件选择、RPC、Preferences 总开关与单 Harness 开关、备份与恢复均已实现。写入和恢复使用临时文件及 rename,并通过摘要检查保留同步期间的手动修改。但 #syncTarget 仅在没有备份清单时检查配置根目录是否存在。若全局 sync() 期间目录已删除但备份仍存在,代码会继续同步;atomicWriteFile 会重新创建目录。[#740] 只允许在打开或恢复会话时创建缺失目录。现有测试覆盖 syncHarness() 创建目录,但未覆盖目录删除后调用全局 sync()。

Resolution

修改 #syncTarget:当 createMissingRoot 为 false 且配置根目录不存在时,启用同步必须直接返回,不得因备份清单存在而创建目录或写入文件。保留 syncHarness() 创建缺失目录的行为。新增回归测试,验证删除配置根目录后调用全局 sync() 不会重建目录或写入目标文件,并验证 syncHarness() 仍可创建该目录并同步指令。

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Host Runtime 硬编码了 19 个 Harness 的配置目录、环境变量和指令文件名,违反边界规则。

resolveExternalUserInstructionsTargets 在 Host Runtime 中写死了 CLAUDE_CONFIG_DIR、KIRO_HOME、OMP_CODING_AGENT_DIR、ZCODE_DATA_BASE_DIR 等 Harness 专属细节,以及各自的指令文件路径。

仓库规则要求这类细节留在对应 Adapter 内。新增或调整 Harness 时,也不应该再修改 Host 代码。

建议在 Adapter/插件的公共契约中增加可选能力,例如 userInstructionsTarget(environment)。该能力返回 rootDir、filePath 和 displayPath。Host 只遍历已加载插件的这个能力。

这项改动较大。如果本 PR 不处理,请至少记录后续任务。

As per coding guidelines: "Harness-specific protocol details must remain inside the corresponding Adapter." 以及 "Host Runtime loads installed plugins through public contracts, not direct imports of concrete Adapter packages."

单个目标失败会中断其余 Harness 的同步或恢复。

sync() 在 for 循环中依次 await #syncTarget。任一目标抛错(例如 ~/.claude 无写权限),后续目标都不会处理。

用户关闭总开关时,设置已经写入磁盘。如果前面某个目标恢复失败,后面的 Harness 仍保留被替换的指令文件。set() 随后抛错,UI 显示失败,但磁盘上的设置已经变更,UI 与磁盘状态不一致。

建议逐目标捕获错误,处理完所有目标后再汇总抛出。

并发同步会丢失用户原始指令文件,需要串行化 #syncTarget。

sync() 和 syncHarness() 都会调用 #syncTarget。其内部流程是先 #readBackup,再 readOptionalFile,再 #writeBackup,最后 atomicWriteFile。这些步骤没有任何串行化。

触发路径如下:Host 启动时 sync() 与首个外部会话的 syncHarness() 同时运行,或者两个会话同时打开同一个 Harness。

  1. A 和 B 都读到 existingBackup === null。
  2. A 读取原文件,写入 { hadOriginal: true, originalContent: 原文 },再把文件替换为 Codex 内容。
  3. B 此时读到的 currentContent 已是 Codex 内容。B 写入 { hadOriginal: true, originalContent: Codex 内容 },覆盖 A 的备份。

结果是原始文件永久丢失,关闭开关后恢复出来的仍是 Codex 内容。

另外有两点:

  • external-thread-runtime.ts 每次调用都会 new HarnessUserInstructionsStore(...)。因此实例级锁无效,必须使用模块级队列,或者注入共享的 store 实例。
  • 多个 Host 进程(GUI 与 shared-thread owner)也可能同时同步。进程内队列无法覆盖这种情况,需要对备份目录加文件锁,或使用 open(..., "wx") 的独占创建来写首份备份。
建议修复(进程内串行化)
+let syncQueue: Promise<void> = Promise.resolve();
+function serialized<T>(operation: () => Promise<T>): Promise<T> {
+  const run = syncQueue.then(operation, operation);
+  syncQueue = run.then(
+    () => undefined,
+    () => undefined,
+  );
+  return run;

   async #syncTarget(
     target: ExternalUserInstructionsTarget,

+    target: ExternalUserInstructionsTarget,
+    active: boolean,
+    codexContent: string | null,
+    createMissingRoot: boolean,
+  ): Promise<void> {

Based on learnings: 先校验再原子替换的流程,原子性本身不保证目标自校验以来未被改动;并发写入方需要协调,否则应失败关闭。

Keep the fixed Model client method allowlist in sync with the two
user-instruction settings methods added by this branch.

Validation: isolated runtime Object.keys check reproduces the baseline
mismatch and passes with all 42 expected methods; an unexpected method
still fails. Prettier check passes. Full Vitest and renderer build were
not run locally because the complete workspace dependencies are absent.

directoryExists 把所有错误都当作“目录不存在”。

catch 会吞掉 EACCES、ELOOP、EPERM 等错误并返回 false。此时 sync() 会静默跳过该 CLI。用户已开启同步,却得不到任何诊断信息。

只把 ENOENT 和 ENOTDIR 视为“不存在”。其他错误应继续抛出。run-host-runtime.ts 已经记录 sync() 的失败。

同时保留有效和悬空符号链接。

当前的 rename(temporaryPath, filePath) 会替换链接本身。#syncTarget 在同步和恢复时都会执行此操作,因此 dotfiles 链接会丢失。

realpath 可以处理有效链接。它不能处理悬空链接,因为 realpath 会失败并回退到 filePath。因此,悬空链接仍会被普通文件替换。停用同步后,恢复流程也不能恢复该链接。

外部修改的目标内容可以由现有 digest 分支保留,但前提是链接本身没有被首次写入替换。请使用 readlink 等方式解析有效和悬空链接的最终目标,并将临时文件重命名到该目标路径。仅添加 realpath 回退不满足恢复原始链接的要求。

将 Harness 专属的指令文件元数据移入 Adapter。

harness-user-instructions.ts 在 Host Runtime 中硬编码了 19 个 Harness 的 ID、配置根目录环境变量、指令文件名和目标路径,例如 CLAUDE.md、GEMINI.md 和 QWEN.md。

仓库规则要求:Harness-specific protocol details must remain inside the corresponding Adapter. 这些路径和文件名是 Harness 的原生集成细节。当前插件公共契约(HarnessPluginModule)和严格 manifest 都没有用户指令能力。因此,插件无法声明这些信息。新增或移除需要同步指令的 Harness 时,必须修改 Host 代码。

WorkBuddy Adapter 已经通过 configDirectoryEnvironmentVariables 和 defaultConfigDirectoryName 声明配置目录。这与本文件的做法不一致。

建议在公共插件契约中增加可选的 userInstructions 能力。各 Adapter 声明自己的配置根目录、环境变量和指令文件名。备份、同步和恢复逻辑可以继续由 Host 负责。此改动涉及 shared-contracts、插件 manifest 和各 Adapter,范围较大,可以另开 issue 跟进。

损坏的备份文件会被当作不存在而覆盖,原始指令可能永久丢失。

#readBackup 在 JSON 解析或 schema 校验失败时返回 null,不报告错误。若目标文件已包含同步后的 Codex 指令,普通同步会进入 !existingBackup 分支。该分支把当前内容(即 Codex 指令)记录为 originalContent,并覆盖损坏的备份。原始用户指令随之丢失。之后停用同步时,代码会把 Codex 指令恢复为"原始内容"。

损坏的备份元数据应视为读取失败,而不是视为无备份。与 #readStored 保持一致:只有文件不存在时返回默认状态。内容无效时,应保留原备份文件、拒绝覆盖,并报告错误。修复前需确认 sync() 对该异常的处理方式,以免影响其他 harness 的同步。

保存请求进行中时禁用所有开关,防止旧状态覆盖新修改。

save() 在请求进行中只显示 pending,不禁用总开关和 harness 开关。用户可以在前一次请求返回前再次切换。

两个处理函数都基于 currentSettings 构造完整请求体。该对象只在 renderSettings() 中更新,即请求返回后才更新。因此后发请求会回退前一次未返回的修改:

  • 关闭总开关后,立即切换某个 harness:第二个请求使用旧的 enabled: true。总开关可能被重新启用,并触发 sync() 写入外部 CLI 的用户指令文件。第一个响应因版本检查被忽略,界面最终显示被回退的状态。
  • 关闭某个 harness 后,立即切换总开关:第二个请求使用旧的 disabledHarnesses,前一次的 harness 禁用被丢失。

修复方式是在保存期间禁用所有开关。同一时间只保留一个设置请求,renderSettings() 在响应返回后重新启用开关。

Minor · 停用时不要因 Codex 源文件读取失败而跳过恢复。 · harness-user-instructions.ts:376-381

packages/host-runtime/src/harness-user-instructions.ts:376-381
Minor · Functional Correctness · Quick win

停用时不要因 Codex 源文件读取失败而跳过恢复。

sync() 在目标循环前无条件调用 readCodexUserInstructions()。若 $CODEX_HOME/AGENTS.override.md 不可读取(例如 EACCES),或该路径是目录(EISDIR),readOptionalFile() 会抛出错误。sync() 随之中断,#syncTarget() 不会执行。

set({ enabled: false }) 会先持久化停用设置,然后调用 sync()。因此,设置已变为停用,但已备份的 harness 文件不会恢复,同步后的文件仍保留。

停用分支不需要源内容。#syncTarget() 仅在 active && codexContent !== null 时使用 codexContent。只在启用时读取源文件,可保持启用行为不变,并使停用路径不再依赖源文件可读性。

get() 和 syncHarness() 也会读取源文件,本建议不修改这两处。

建议修复

   async sync(): Promise<void> {
     const stored = await this.#readStored();
     const disabled = new Set(stored.disabledHarnesses);
-    const source = await readCodexUserInstructions(this.#environment);

+      ? (await readCodexUserInstructions(this.#environment)).content
+      : null;
     const targets = resolveExternalUserInstructionsTargets(this.#environment);
     for (const target of targets) {
       const active = stored.enabled && !disabled.has(target.harnessId);
-      await this.#syncTarget(target, active, source.content, false);
+      await this.#syncTarget(target, active, codexContent, false);

packages/host-runtime/src/harness-user-instructions.ts:336-350
Minor · Stability & Availability · Quick win

禁用状态下,get() 遇到不可读的 AGENTS.override.md 会失败。

当 AGENTS.override.md 是目录,或权限不允许读取时,readCodexUserInstructions() 会抛出非 ENOENT 错误。get() 无条件等待该调用,因此即使 enabled 为 false,GET 也会返回错误。Preferences 初始加载随之失败,用户无法查看或启用各 harness 开关。

仅在禁用时跳过内容读取无法修复此路径。displayPath 取决于 override 内容是否非空,因此不能只根据路径选择来源。

只在禁用状态下捕获读取错误,并回退到默认显示路径。启用状态下仍须抛出错误。

回退路径仅用于显示,不表示启用同步后会读取哪个文件。

感谢这个 PR。统一维护用户指令的需求可以理解,但我们不计划合并当前方案,主要原因是产品职责边界,而不是还缺哪些实现修补。

codexhost 的职责是通过 Harness 的原生接口接入它,保留各 Harness 自己的配置和行为。这个方案会将 Codex 的全局指令写入各 Harness 自己的全局文件(例如 ~/.claude/CLAUDE.md、~/.pi/agent/AGENTS.md)。它虽然没有修改 Harness 的程序代码,但启用后会改变这些 CLI 的全局行为,包括不经过 codexhost 启动的会话;影响并不局限于 codexhost 内的 Thread。

我们不希望 codexhost 承担替换、备份和恢复各 Harness 全局指令文件的管理职责。因此,即使完善备份恢复、并发和路径处理,也不会改变我们对当前方案的合并决定,不需要为推动合并继续补齐这些细节。

如果用户希望共用一份全局指令,可以自行管理文件同步;若未来考虑会话范围的指令传递,应以相应 Harness 明确支持的原生接口为基础另行讨论,而不是覆盖它的全局配置。

感谢理解和贡献。
