+- Rust：`agent/direct_codex_user_item/model.rs`、`validation.rs`、`wire.rs`、`codex_app_server/mod.rs` 与对应测试。
+- 文档：父规范与本里程碑/实施计划。

+
+1. 先扩展前端 Skill catalog/节点/草稿 content，保持素材行为不变并补前端测试。
+2. 扩展 canonical Rust part 与 ts-rs 绑定，补序列化和失败校验测试。
+3. 接通 Codex wire `type: skill` 转换和受控路径解析，补历史/重放测试。
+4. 完成入口透传、定向验证和文档证据；每个切片单独中文提交。

+
+## 目标
+
+在现有 Lexical `ResourceReferenceInput` 中增加 Codex 风格 `$skill-name` 提及。用户选择 Skill 后，编辑器保留与文本相对顺序一致的原子节点；DirectProject canonical user item 保存稳定 Skill 名称，Rust 只允许当前已启用且 app-server 已发现的 Skill，并在 `turn/start` 转换为 Codex 原生 `type: "skill"` 输入项。
+
+## 范围
+
+- Skill 候选数据从当前 DirectProject 的已启用 Skill catalog 派生。
+- `$` typeahead 菜单、键盘选择、鼠标选择、Esc/Enter 交互与现有 `@` 菜单一致。
+- Skill inline 节点和 `content[]` 顺序恢复。
+- canonical `agc_skill_reference` part 的 ts-rs 类型、Rust 校验、历史写入与 Codex wire 转换。
+- 现有素材、运行区域、assistant、附件和工具 activity 行为保持不变。
+
+## 不在范围内
+
+- Skill 导入、启用、禁用、重命名和 app-server `skills/list` 生命周期改造。
+- 普通自然语言自动分类 Skill；只支持显式 `$skill-name` 选择。
+- Skill 正文预加载、Skill 内容编辑或新的权限/工具能力。
+- SpacetimeDB、HTTP API 和 assistant item 协议变更。
+
+## 验收标准
+
+- [ ] 输入 `$` 可显示并过滤可用 Skill，候选项显示名称和描述。
+- [ ] 选择 Skill 后插入原子 `$name` chip，文本与素材/运行区域的相对顺序保持不变。
+- [ ] canonical user item 只保存 Skill 稳定名称，不保存正文、凭据或宿主私密路径。
+- [ ] Rust 拒绝未知、禁用、未发现或名称非法的 Skill；失败时不写历史、不启动回合。
+- [ ] 合法 Skill 在 Codex wire input 中生成 `type: "skill"`、`name`、受控 `path`，顺序与 canonical content 一致。
+- [ ] 无 Skill 的旧消息、素材引用和标准 `response_item` 读取行为不变。
+
+## 证据要求
+
+- 前端：Lexical 草稿顺序、候选过滤、chip 原子性与 `$`/`@` 共存测试。
+- Rust：模型序列化、Skill catalog 校验、wire 转换、失败关闭和历史重放测试。
+- 运行时：DirectProject app-server smoke（环境可用时）。
+- 门禁：相关 Vitest、AGC Rust 定向测试、`npm run check:encoding`、`npm run check:doc-index`、`git diff --check`。
