 Claude 根插件是手工维护的 canonical surface：skills 定义 Retrieval/Reflection/Stable Knowledge Gate 与显式工作流，三个 agent 定义调查、候选捕获和正式写入边界。Codex 的 skills、agents、manifest 与 marketplace 是转换产物，不得成为独立设计源。
 
-两种宿主都把确定性行为收敛到外部 `@tokenroll/llmdoc` CLI。统一调用形式是 `npx -y @tokenroll/llmdoc <cmd>`：不向消费仓库写依赖；需要复现时在包名中固定版本；不得退回会解析错误包名或交互挂起的裸调用。

+
+生命周期 hook 属于不同的启动边界：宿主从消费仓库的 cwd 调用 npm，而该仓库可能暴露同名的 local/`file:` 依赖。npm 会让这个依赖先满足普通 package identity；即使其 bin 尚未构建或不是应运行的发布 runtime，进程也不会自动回退到 registry CLI。hook 因此必须通过一个不同 identity 的 scoped npm alias 请求 `@tokenroll/llmdoc`，再调用它暴露的 `llmdoc hook *` bin。alias 只隔离 package 解析，不改变共同 runtime、参数或输出契约，也不应用于日常交互命令。
 
 ## 生成与一致性不变量
 
 转换必须在临时副本生成后替换式同步，因为生成器不保证清除陈旧输出。Codex 角色文本不手工维护；宿主特有 front matter/TOML 可以不同，实际 skill 与 agent 指令正文必须与 Claude canonical 一致。被 skill 按需加载的 reference 同样属于可执行 prompt surface：Codex 镜像必须包含相同正文，相关 skill/agent 也必须保留可发现的加载路径。
 
-`scripts/check-codex-surface.mjs` 在 CI 中机械校验版本/marketplace 身份、五个 skill 与三个 agent 的正文一致性、按需 reference 的正文 parity 与加载路径、Reflection Gate 约束和 hook 调用。它还分别遍历 `skills/` 与 `.agents/skills/`，用 `gray-matter` 解析每份 `SKILL.md` 的 YAML front matter，并要求 `name`、`description` 是非空字符串；这是两侧各自的语法门槛，不替代跨宿主正文 parity。人工 checklist 只补宿主 UI policy、知识拓扑质量与信任模型等无法从正文等价判断的部分。

+## Lifecycle hook 发布验证
+
+hook 的发布边界包含宿主 cwd 中的 npm package 解析、发布包的 bin 链接和 CLI 启动，而不只是 `hook` 命令进入后的业务逻辑。发布验证必须从 `hooks/hooks.json` 读取并执行真实 lifecycle 命令，在可见同名 local/`file:` 依赖的消费方环境中确认 alias 仍选择发布 runtime，并验证 SessionStart 的文本与 Stop/PreCompact 的 JSON 契约。静态命令前缀检查、直接运行仓库 `dist` 或只调用内部 hook handler 都不能替代这项验证，因为它们绕过了发生遮蔽的启动层。

 ## 外部宿主指引复核不变量
 
 公开的外部宿主安装或启用指导在发布前必须依据宿主当时的官方用户文档复核。仓库中存在或本地可调用的命令，不足以单独成为主快速入门路径的依据；可选、恢复性或其他条件性步骤必须保留其条件语义。具体命令、UI 文案与步骤序列属于易变事实，不在稳定知识中固定。
