+- **Reviewed document shortcuts** (#880) — adds public document shortcuts for
+  safe local downloads, content and history, review, media and style, and
+  document access/sharing workflows, while retaining reviewed compatibility
+  identities and confirmation safeguards for writes.
+- **Mentions in chat replies** (#881) — `chat message reply` now supports
+  `--at-open-dingtalk-ids` and `--at-all`, forwarding reply mention fields and
+  adding any required mention placeholders without changing existing send
+  behavior.
+
+## [1.0.57-beta.2] - 2026-08-05

 ### Fixed

- **Stable Chat command compatibility** — restores the hidden migration
-  entries for `chat send`, `chat history`, and their `im` aliases that PR #860
-  removed, preserving the v1.0.56 command surface while directing callers to
-  the supported `chat message send/list` commands.

+- **Chat reply mentions** — `dws chat message reply` can @ specified group members with `--at-open-dingtalk-ids` or @ everyone with `--at-all`, forwarding the existing `send_personal_message` mention fields and automatically adding missing current-user `<@id>` / `<@all>` placeholders.
 - **Pinned MCP metadata retired** — deletes `internal/cli/schema_mcp_metadata.json` and removes its embed/loader/fallback role from Schema assembly. Catalog now assembles from Contract/ParamDecl/Interface + Cobra only; `make fetch-mcp-metadata` remains an optional diagnostic dump under `artifacts/` and refuses the retired pin path. Policy bans the pin from reappearing.
 - **MCP service review retired** — deletes `schema_mcp_service_review.json` and removes its policy jq / outputguard / test disposition gate (`notify` → `out_of_surface`, snapshot hash pin). No replacement ledger.
 - **Hints retired; ContractDecl is the leaf Schema source** (#830) — `schema_hints/`, Manual/Schema hint overlays, and `schema_agent_metadata/` delivery are removed. Selection, safety, parameters, and interface facts declare on ProductDecl / leaf `Contract` (`corecmd.ContractDecl` + `contract.ParamDecl` / `Safety`). Authoring renamed `SchemaDecl` → `ContractDecl`; nested fields reuse `contract.*` directly.

 兼容入口 `dws schema list` 等价于根概览。`schema --all` 是完整导出：每个工具都包含完整 leaf 参数、约束和安全语义。它输出很大，只用于明确要求的全量导出、审计、CI 或参数 baseline；普通 Agent 任务应按概览、产品/分组、leaf 渐进查询，不要把 `--all` 直接注入上下文。`schema --all --compact` 虽受支持，但会裁掉 provenance 和接口映射字段，不能作为完整 baseline。

-Leaf 查询、`--all` 中对应工具和 Catalog full tool 均由同一个 resolved `ToolSpec` 投影，内容必须一致；概览、产品/分组和 Catalog summary 也由该 `ToolSpec` 的统一 summary 投影生成。通过 alias 查询时，只允许 `cli_path` 和 `is_alias` 发生视图变化，参数、安全和接口契约不得变化。

-`--compact` 是 Schema 的展示选项。当前版本支持该 flag；若兼容旧二进制时收到 `unknown_flag: --compact`，用同一个 Schema 查询去掉 `--compact` 重试。这只降低输出裁剪能力，不表示 leaf 不存在，也不能改用 Schema 查询业务数据。

+# DWS Skill 内容框架合同
+
+> 本分支权威合同：`skills/mono` / `skills/multi` 的**内容组织**与 zip 内容树形状。  
+> 不做安装/升级行为约定。质检见 [skill-mono-multi-qa.md](skill-mono-multi-qa.md)。  
+> 对齐调研：[skill-wukong-align-plan.md](skill-wukong-align-plan.md)。
+
+## 1. 两棵内容树
+
+| 树 | 路径 | 角色 |
+|---|---|---|
+| **mono**（单 skill） | `skills/mono/` | 单一 `SKILL.md` 入口 + `references/products/*` 产品面 + 全局协议 |
+| **multi**（多 skill） | `skills/multi/` | 平铺 `dingtalk-*` 产品 skill + 必选 `dingtalk-shared` |
+
+Agent / 安装面选哪棵树由**行为分支**决定；本文件只规定树内合同。
+
+## 2. Multi 目录合同（如何新增一个产品 skill）
+
+新建 `skills/multi/<name>/` 时必须满足：
+
+1. **命名**
+   - 产品 skill：`dingtalk-<product>`（小写、连字符）
+   - 共享 skill：仅允许 `dingtalk-shared`
+2. **根文件**
+   - 必有 `SKILL.md`（YAML frontmatter + 正文）
+   - `references/` 推荐；无 reference 的 skill（如极简 profile）须在质检 omit 表登记
+   - `scripts/` 可选；脚本须被本 skill 树内某 `.md` 引用，或进入 orphan allowlist
+3. **Frontmatter 最小集**（产品 / shared）
+   - `name`：与目录名一致
+   - `description`：非空，含触发意图与边界
+   - `metadata.category`：`product` 或 `shared`（允许历史写法把 `cli_version` 放在 frontmatter 顶层）
+   - `metadata.requires.bins`：含 `dws`
+4. **契约块**
+   - 产品 skill 推荐内嵌 `<!-- DWS_RUNTIME_CONTRACT_START -->…END -->` **或** 明确 PREREQUISITE 指向 `dingtalk-shared`
+   - `dingtalk-shared` 承载跨产品路由与全局协议落点
+5. **与 mono 映射**
+   - 每个 mono `references/products/<stem>`（文件或目录）必须在
+     `skills/content-qa/mono-multi-coverage.yaml` 有 `coverage` 或 `omit_coverage` 行
+
+### 2.1 推荐骨架
+
+```text
+skills/multi/dingtalk-example/
+├── SKILL.md
+├── references/
+│   ├── example.md          # 主产品面
+│   └── …                   # 子章节 / 意图表
+└── scripts/                # 可选；须被 md 引用
+    └── example_helper.py
+```
+
+## 3. Mono 目录合同（质检对照基准）
+
+```text
+skills/mono/
+├── SKILL.md
+├── references/
+│   ├── products/           # 覆盖质检主源
+│   ├── error-codes.md      # 全局协议示例
+│   ├── error-codes.md
+│   └── …
+└── scripts/
+```
+
+- `references/products/` 下每个顶层 stem（`.md` 去后缀或子目录名）计入覆盖索引。
+- 同 stem 的 `.md` + 子目录视为同一产品面（如 `doc.md` + `doc/`）。
+
+## 4. 共享内容（`dingtalk-shared`）
+
+| 职责 | 落点 |
+|---|---|
+| 跨产品路由 / 工作流 | `references/routing.md`、`workflow-routing.md`、`intent-guide.md` |
+| 运行时最小契约长文 | `references/runtime-contract.md`（受 context-budget 约束） |
+| 全局协议（确认门禁 / Schema 教学等） | `references/`；见质检基线 |
+| 与 mono 全局文同名迁移 | `error-codes`、`url-patterns`、`capability-limits`、`channel-login`、`global-reference`、`recipes/`（`conventions.md`、`meta.md`、`lite-catalog.md`） |
+
+产品专属规则（如 AI 表格 `field-rules`）允许下沉到对应 `dingtalk-*`，须在覆盖表注明。
+
+## 5. Zip 内容布局合同（形状，非安装默认）
+
+发布物 `dws-skills.zip`（及 embed 同源）内容树形状：
+
+| Zip 路径 | 含义 |
+|---|---|
+| `<root>/` | mono 内容副本（兼容旧面） |
+| `<root>/mono/` | 与 `skills/mono/` 同构 |
+| `<root>/multi/` | 与 `skills/multi/` 同构 |
+
+质检可断言源树形状；**不**断言安装器默认解压哪棵。
+
+## 6. 与悟空 `dingtalk-skills/` 对照（组织概念 only）
+
+| 维度 | DWS `skills/multi` | 悟空 `dingtalk-skills/`（develop） |
+|---|---|---|
+| 布局 | flat `dingtalk-*` + `dingtalk-shared` | 同构 flat |
+| 集合 | 产品 skill + shared（含 event/profile/…；dev/skill 等长尾落在 misc） | 更小产品集（如 attendance/report 独立目录） |
+| 质检权威 | **mono 单 skill 树** | 不作为 DWS 覆盖基准 |
+| 不移植 | `_install.sh` / bundle / dual / Qwen overlay | — |
+
+悟空独有命名（如 `dingtalk-attendance`）在 DWS 中由 `dingtalk-misc` 承接对应 mono `attendance*` / `report` / `oa` / `sheet` / `dev` 等面——见覆盖表。
+
+## 7. 变更流程
+
+1. 改 / 增内容 → 更新 `skills/content-qa/mono-multi-coverage.yaml`（coverage 或 omit）  
+2. 跑 `make skill-mono-multi-content`（或 `make policy`）  
+3. 失败则修内容或更新 reviewed omit（disposition + 原因），**禁止**用安装默认值绕过

+
+## 1. 质检矩阵
+
+| ID | 类型 | 输入 | 通过准则 |
+|---|---|---|---|
+| **G1 形状** | 结构 | `skills/multi/*` | 仅 `dingtalk-*`（含必选 `dingtalk-shared`）；每目录有 `SKILL.md` |
+| **G2 结构** | 结构 | 各 `SKILL.md` frontmatter | `name`==目录名；非空 `description`；`category`∈{product,shared}；`requires.bins` 含 `dws` |
+| **G3 覆盖** | 覆盖 | mono `references/products/*` 顶层 stem | 每 stem ∈ `coverage` 或 `omit_coverage`；coverage 目标 skill/refs 存在 |

+
+## 2. 有意省略 / 延期登记格式
+
+YAML（见 coverage 文件）：
+
+```yaml
+omit_coverage:
+  - mono: simple
+    disposition: covered_by   # covered_by | defer | wontfix
+    via: dingtalk-misc        # optional
+    reason: "拆入 oa/devdoc…"
+
+omit_global:
+  - id: field-rules-global
+    mono_path: references/field-rules.md
+    expected_multi: dingtalk-aitable/references/field-rules.md
+    disposition: covered_by
+    reason: "AI 表格字段规则已下沉到 dingtalk-aitable；G3/coverage 不强制全局同名"
+
+orphan_scripts_allowlist:
+  - path: dingtalk-misc/scripts/report_received_today.py
+    disposition: defer
+    reason: "pending report.md reference"
+```
+
+**处置原则**：质检失败 → 修**内容**或更新 reviewed omit；**不**改安装/升级默认。
+
+## 3. 缺口基线（相对 mono）

+
+## 0. TL;DR
+
+1. **本分支 = skill 内容框架 + 相对 mono 的内容质检**：固化 `skills/multi` 组织合同，并用 **mono 单 skill 布局作对照基准**做覆盖/结构/漂移门禁（文档 + CI 内容护栏）。
+2. **对齐悟空**：只取内容树组织概念；质检以 **DWS-native** 设计为主（已有 policy/测试可复用）。悟空 `validate-multiskill-bundle.py` 仅借鉴「frontmatter / 断链 / requires」类检查思路，**不**移植 bundle/安装校验。
+3. **安装/升级行为**与 `402429ac`/`d5c8982c` → **单独 follow-up 分支**，本方案只登记。
+4. 质检 **不改**默认安装哪棵树；只保证 multi 内容相对 mono **可解释、可覆盖、可回归**。

+### 0.1 IN SCOPE
+
+| 类别 | 包含 |
+|---|---|
+| 内容树结构 | `skills/mono/` 与 `skills/multi/<name>/` 目录合同 |
+| 单 skill 约定 | `SKILL.md` frontmatter / 契约块 / Golden Route；`references/`；可选 `scripts/` |
+| 共享内容 | `dingtalk-shared` 职责与被引用方式；与 mono 全局文映射（文档级） |
+| 命名与集合 | `dingtalk-*` + `dingtalk-shared`；相对悟空的共有/独有清单（文档） |
+| Zip **内容布局合同** | `mono/` / `multi/` / 根 mono 副本的内容含义与树形状；不改安装默认 |
+| **Mono↔multi 内容质检** | 覆盖、结构、漂移三类门禁；复用/扩展现有 policy 与测试；缺口修复属内容编辑（另批或同分支内容 Phase） |
+| 内容架构文档 | 本文件 + 可选短文（架构合同 + 质检矩阵） |
+
+### 0.2 OUT OF SCOPE
+
+| 类别 | 去向 |
+|---|---|
+| 安装默认 multi、upgrade always-multi | Follow-up 分支（`402429ac`/`d5c8982c`） |
+| `LocateSkillsRoot` / `skill_setup` / `paths.go` / `skillhome` / install 脚本行为 | 同上 |
+| 安装/运行时 manifest、state.json、mode 切换、telemetry header | 拒绝或行为分支 |
+| 悟空 `_install.sh` / dual / Qwen / RewindDesktop / pod | 拒绝 |
+| 非 skill 内容的 CLI 功能（schema/shortcut 代码等） | 拒绝 |
+| 把质检做成「改安装默认值」的后门 | 拒绝 |
+

+
+## 1. 内容现状盘点
+
+### 1.1 DWS `skills/mono`（质检对照基准 · 单 skill）
+
+```text
+skills/mono/
+├── SKILL.md
+├── references/
+│   ├── products/<area>.md|…/   # 产品能力面（质检「覆盖」主源）
+│   ├── error-codes.md、…  # 全局协议（无 recovery 闭环）
+│   └── best_practices/…
+└── scripts/
+```
+
+### 1.2 DWS `skills/multi`（内容主体）
+
+```text
+skills/multi/
+├── dingtalk-shared/     # 跨产品契约 / routing / 全局协议应落点
+└── dingtalk-*/     # 19 产品 + 各 references、scripts
+```
+
+仅 DWS 有（悟空无）：dev, event, hrbrain, markdown, pat, profile, skill。
+
+### 1.3 悟空 `dingtalk-skills/`（内容组织对照，非质检权威）
+
+Flat `dingtalk-*` + `dingtalk-shared`；单 skill 骨架同构。**不作为 mono 覆盖基准**（集合更小、不同源）。
+
+### 1.4 Zip 内容布局合同
+
+| Zip 路径 | 内容含义 |
+|---|---|
+| `<root>/` | mono 副本（兼容） |
+| `<root>/mono/` | 显式 mono 内容源 |
+| `<root>/multi/` | 与 `skills/multi/` 同构 |
+
+质检可断言「源树形状」；**不**断言安装面默认选哪棵。
+
+### 1.5 现有 DWS skill 内容质检资产（复用清单）
+
+| 资产 | 作用 | 与 mono↔multi 质检关系 |
+|---|---|---|
+| `scripts/policy/check-skill-commands.sh` + `skill-command-check/` | Skill 文内 `dws …` 命令路径存在性 | **复用**（命令真实性）；非覆盖映射 |
+| `scripts/policy/check-skill-context-budget.sh` | chat/event/mono/`dingtalk-shared` 上下文预算与冷启动约束 | **复用**（结构/预算）；可扩展 shared 引用规则 |
+| `scripts/policy/check-multi-im-skill-chain.sh` + `multi-im-skill-chain/` | IM 意图单默认路由、retired scripts、handoff | **复用**（chat/event 链）；面窄 |
+| `test/unit/skill_docs_policy_test.go` | 退役命令、event 扁平输出契约等 | **复用**；可加 mono↔multi 断言 |
+| `test/unit/whiteboard_skill_docs_test.go` | mono/multi whiteboard recipes **字节一致** | **样板**：产品面「同源文件」门禁范式 |
+| `test/skill_static`（`-tags skill_verify`） | 文内命令 vs Cobra；multi 查 flag | **复用**（opt-in 深度）；非 CI 默认全量时可保持 tags |
+| `test/skill_e2e` / `test/run_skill_tests.py` | 执行层 / 用例驱动 | **偏行为**；本分支质检默认不依赖 e2e |
+| `Makefile` → `policy` 含 context-budget、multi-im-skill-chain；`skill-command-integrity` 独立 | 已有 CI 钩子 | 新门禁优先挂同类 policy / `test/unit` |
+
+**缺口（尚无的门禁）**：系统的「mono `references/products/*` → multi 目录/文」覆盖表；frontmatter 全集完备性；orphan scripts。全局协议中 **确认门禁 / Schema 教学已补**；**recovery 闭环已从 skill 移除（不再作为缺口）**。
+
+### 1.6 悟空侧类比质检
+
+| 悟空 | 说明 | 本分支 |
+|---|---|---|
+| `scripts/validate-multiskill-bundle.py` | 校验 **已打好的 bundle zip**：frontmatter keys/category、`requires`、markdown 断链、scenario 编排 | **Adapt 思路** → DWS 源树（`skills/multi` + 对照 mono），不跑 zip 安装语义 |
+| `sync-monolith-to-multiskill.py` | mono→multi 派生 | **不**作默认质检手段；DWS 直接维护 multi |
+
+结论：**DWS-native mono↔multi 质检**；悟空仅参考检查维度。
+
+---
+
+## 2. Diff（内容组织 + 质检视角）
+
+### 2.1 已同构
+
+Flat `dingtalk-*` + `dingtalk-shared`；`SKILL.md` + `references/`（+ 可选 `scripts/`）。
+
+### 2.2 分叉与已知内容风险（质检要盯的）
+
+| 风险 ID | 现象（线索） | 质检类型 |
+|---|---|---|
+| **C-cov** | mono `products/*` 能力面在 multi 无对应 skill/reference，或未登记「有意省略」 | 覆盖 |
+| **C-struct** | multi 缺 frontmatter 字段、`references/`、`DWS_RUNTIME_CONTRACT`、对 `dingtalk-shared` 引用不一致 | 结构 |
+| **C-drift-global** | 曾关注 recovery / 确认 / Schema；现确认与 Schema 已在 `dingtalk-shared`，**recovery skill 文档已删除** | 漂移（协议） |
+| **C-drift-orphan** | multi（或 mono）scripts/refs 无文档引用；或 routing 指向无索引产品（留档 X1/M6） | 漂移（孤儿） |
+| **C-pair** | 应对齐的成对文件（如 whiteboard recipes）内容不一致 | 漂移（成对） |
+
+### 2.3 Reject
+
+悟空安装包校验整文件照搬、内容集 19→12 砍产品、安装行为门禁冒充内容质检。
+
+---
+
+## 3. Goals / Non-goals
+
+### 3.1 Goals
+
+1. 固化 multi **内容目录合同**与 mono↔multi **映射说明**。  
+2. 建立 **质检矩阵**（覆盖 / 结构 / 漂移）并以 mono 为对照基准；有意省略必须 reviewed 登记。  
+3. **复用** §1.5 资产；新增门禁走 `scripts/policy` 或 `test/unit`，内容-only。  
+4. （可选）纯内容元数据；**禁止**被安装引擎读取改行为。  
+5. 质检失败 → 修 **内容**或更新「有意省略」表，不改 setup/upgrade。
+
+### 3.2 Non-goals
+
+安装/升级翻转；cherry-pick 行为提交；取消产品；悟空客户端；非 skill CLI 功能；用质检驱动默认 multi 安装。
+
+---
+
+## 4. 分期（内容框架 + 质检 · 均无安装引擎）
+
+> 批准前 **零编码**（含不实现新 gates）。**已执行**：Phase 1–3 见文首状态。
+
+### Phase 0 — 方案冻结（本文）

+### Phase 1 — Multi 内容目录合同 + 架构短文 ✅
+
+| | |
+|---|---|
+| **范围** | `skills/multi` 目录合同；与悟空内容树对照表；zip `multi/` 同构合同 |
+| **触达** | `docs/skill-content-framework.md` |
+| **验收** | 可指导「如何新增 dingtalk-* 内容目录」 |
+
+### Phase 2 — Mono↔multi **内容质检规格**（矩阵 + 缺口基线） ✅
+
+| | |
+|---|---|
+| **范围** | 质检规格 + 覆盖/omit 机读表 + 缺口 disposition |
+| **触达** | `docs/skill-mono-multi-qa.md`、`skills/content-qa/mono-multi-coverage.yaml` |
+| **验收** | 矩阵可人工抽查；缺口均有 disposition |
+
+### Phase 3 — 质检落地：CI 内容护栏（复用 + 新 gate） ✅
+
+| | |
+|---|---|
+| **范围** | G1–G4 自动门禁 |
+| **触达** | `test/unit/mono_multi_skill_content_test.go`、`scripts/policy/check-mono-multi-skill-content.sh`、`Makefile` |
+| **验收** | `make skill-mono-multi-content` 绿；已知缺口走 reviewed omit |
+
+### Phase 4 — 可选：内容包元数据 + 缺口修复波次
+
+| | |
+|---|---|
+| **范围 A** | 纯内容 layout/skill 列表元数据（人不读安装器） |
+| **范围 B** | 按 Phase 2 disposition **修内容**：确认 / Schema 已补；**recovery skill 文档已删除（wontfix 移植）**；orphan 脚本仍走 allowlist（M4 等） |
+| **验收** | 元数据不驱动安装；修复项关闭对应质检失败或转入 omit |
+
+### 延期登记（非本分支）

+| whiteboard 式 mono/multi 成对一致 | **Port（范式）** | 推广到 reviewed 文件对 |
+| `validate-multiskill-bundle.py` 整脚本 | **Reject** | 绑定悟空 zip/Qwen 语义 |
+| `_install.sh` / dual / overlay | **Reject** | 非内容 |
+| 行为 cherry-pick | **Defer** | 另分支 |

+## 6. 与 `402429ac` / `d5c8982c`
+
+| | |
+|---|---|
+| 本分支 cherry-pick？ | **否** |
+| 质检是否替代行为翻转？ | **否** |
+| 行为分支 | 另开；可与内容/质检并行 |
