+## [1.0.2] - 2026-03-29
+
+Deep workspace tooling upgrade: pipeline-based input correction, output filtering, enhanced stdin handling, and multi-endpoint routing.
+
+### Added
+
+- Pipeline engine (`internal/pipeline`) for pre-parse and post-parse input correction
+  - `AliasHandler`: normalises model-generated flag casing (e.g. `--userId` → `--user-id`)
+  - `StickyHandler`: splits glued flag values (e.g. `--limit100` → `--limit 100`)
+  - `ParamNameHandler`: fixes near-miss flag typos (e.g. `--limt` → `--limit`)
+  - `ParamValueHandler`: normalises structured parameter values after parsing
+- Output filtering via `--fields` and `--jq` global flags (`internal/output/filter.go`)
+  - `--fields`: comma-separated field selection for top-level keys (case-insensitive)
+  - `--jq`: jq expression filtering powered by `gojq` library
+- `StdinGuard` for safe single-read stdin across multiple flags in one invocation
+- `ResolveInputSource` unified resolver supporting `@file`, `@-` (explicit stdin), and implicit pipe fallback
+- `@file` / `@-` syntax support for all string-typed override flags in tool commands
+- Chat helper support for `@file` input to read message content from files
+- Tool-level endpoint routing (`dynamicToolEndpoints`) for multi-endpoint products
+- Comprehensive test suites for pipeline handlers, stdin guard, canonical commands, and chat input
+
+### Changed
+
+- `directRuntimeEndpoint` now accepts tool name for finer-grained endpoint resolution
+- `collectOverrides` resolves `@file` / `@-` for all string-typed flags
+- `NewRootCommand` refactored to `NewRootCommandWithEngine` with optional pipeline engine
+- `schema` command no longer hidden (visible in help output)
+- Default output format changed from `table` to `json`
+
+## [1.0.1] - 2026-03-28
+
+Backward-compatible feature and security update after the initial 1.0.0 release.
+
+### Added
+
+- JSON output support for `dws auth login` and `dws auth status`
+- Cross-platform keychain-backed secure storage and migration helpers
+- Atomic file write helpers to avoid partial config and download writes
+- Stronger path and input validation helpers for local file operations
+- Install-script coverage for local-source installs
+
+### Changed
+
+- Improved `auth login` help text, hidden compatibility flags, and interactive UX
+- Added root-level flag suggestions for common compatibility mistakes such as `--json` and legacy auth flags
+- Updated AITable upload parsing to accept nested `content` payloads
+- Refreshed bundled skills metadata for the new CLI version
+
 ## [1.0.0] - 2026-03-27
 
 First public release of DingTalk Workspace CLI.

-## 安装
-
-### 一键安装（推荐）
-
-**macOS / Linux：**
+**macOS / Linux:**
 
 ```bash
 curl -fsSL https://raw.githubusercontent.com/DingTalk-Real-AI/dingtalk-workspace-cli/main/scripts/install.sh | sh
 ```
 
-**Windows (PowerShell)：**
+**Windows (PowerShell):**
 
 ```powershell
 irm https://raw.githubusercontent.com/DingTalk-Real-AI/dingtalk-workspace-cli/main/scripts/install.ps1 | iex
 ```
 
-> 自动检测操作系统和架构，从 [GitHub Releases](https://github.com/DingTalk-Real-AI/dingtalk-workspace-cli/releases) 下载预编译二进制文件，并安装 Agent Skills 到 `~/.agents/skills/dws` — 无需 Go、Node.js 或其他依赖。大多数 AI Agent（Claude Code、Cursor、Windsurf 等）可自动发现 `.agents/skills/` 目录下的技能。
+<details>
+<summary>Other install methods</summary>
 
-> [!TIP]
-> 二进制文件默认安装到 `~/.local/bin`。如果安装后找不到 `dws` 命令，请将其添加到 PATH：
+**Pre-built binary**: download from [GitHub Releases](https://github.com/DingTalk-Real-AI/dingtalk-workspace-cli/releases).
+
+> **macOS users**: If you see "cannot be opened because Apple cannot check it for malicious software", run:
 > ```bash
-> export PATH="$HOME/.local/bin:$PATH"
+> xattr -d com.apple.quarantine /path/to/dws
 > ```
-> 将此行添加到 `~/.bashrc` 或 `~/.zshrc` 以永久生效。
 
-### 预编译二进制文件（手动）
-
-从 [GitHub Releases](https://github.com/DingTalk-Real-AI/dingtalk-workspace-cli/releases) 下载适合您平台的最新二进制文件。
-
-### 从源码构建
+**Build from source**:
 
 ```bash
 git clone https://github.com/DingTalk-Real-AI/dingtalk-workspace-cli.git
 cd dingtalk-workspace-cli
-make build
-./dws version
+go build -o dws ./cmd       # build to current directory
+cp dws ~/.local/bin/         # install to PATH
 ```
 
-这只会构建二进制文件。如需同时将 agent skills 安装到主目录：
+> Requires Go 1.25+. Use `make package` to cross-compile for all platforms (macOS / Linux / Windows x amd64 / arm64).
+
+</details>
+
+## Upgrade
+
+dws has built-in self-upgrade capability. Updates are pulled directly from [GitHub Releases](https://github.com/DingTalk-Real-AI/dingtalk-workspace-cli/releases) with SHA256 integrity verification and automatic backup.
 
 ```bash
-sh scripts/install.sh
+dws upgrade                    # interactive upgrade to latest version
+dws upgrade --check            # check for new versions without installing
+dws upgrade --list             # list all available versions
+dws upgrade --version v1.0.7   # upgrade to a specific version
+dws upgrade --rollback         # rollback to the previous version
+dws upgrade -y                 # skip confirmation prompt
 ```
 
-这会检测本地源码目录，无需从 GitHub 下载即可安装二进制文件和 skills。
+<details>
+<summary><strong>How it works</strong></summary>
 
-## 开始使用
+The upgrade process follows a two-phase atomic flow to ensure consistency:
 
-### 步骤 1：创建钉钉应用
+1. **Prepare** — downloads the platform-specific binary and skill packages to a temporary directory, verifies SHA256 checksums, and extracts/validates all files. If any step fails, the upgrade aborts without modifying the existing installation.
+2. **Apply** — only after all preparations succeed, the binary is replaced and skill packages are installed to all detected agent directories (`~/.agents/skills/dws`, `~/.claude/skills/dws`, `~/.cursor/skills/dws`, etc.).
 
-进入 [开放平台应用开发后台](https://open-dev.dingtalk.com/fe/app?hash=%23%2Fcorp%2Fapp#/corp/app)，在「企业内部应用 - 钉钉应用」点击右上角的**创建应用**，新建一个应用。
+A backup of the current version is automatically created before each upgrade. Use `dws upgrade --rollback` to restore the previous version if needed.
+
+| Flag | Description |
+|------|-------------|
+| `--check` | Check for updates without installing |
+| `--list` | List all available versions with changelogs |
+| `--version` | Upgrade to a specific version (e.g. `v1.0.7`) |
+| `--rollback` | Rollback to the previous backed-up version |
+| `--force` | Force reinstall even if already on the latest version |
+| `--skip-skills` | Skip skill package update |
+| `-y` | Skip confirmation prompt |
+
+</details>
+
+## Getting Started
+
+```bash
+dws auth login            # browser opens automatically
+dws auth login --device   # for headless environments (Docker, SSH, CI)
+```
+
+Select your organization and authorize. That's it.
+
+> If your organization hasn't enabled CLI access, you'll be prompted to send an access request to your admin. Once approved, re-run `dws auth login`.
+
+<details>
+<summary><strong>Organization hasn't enabled CLI access?</strong></summary>
+
+1. After selecting your organization, click "Apply Now" to notify the admin
+2. The admin receives a request card and can approve with one click
+3. Once approved, re-run `dws auth login`

+For enterprise-managed scenarios, create your own DingTalk app:
 
-### 步骤 4：申请白名单
-
-参照页面顶部的 [共创阶段说明](#important)，加入钉钉 DWS 共创群完成白名单配置。
-
-### 步骤 5：使用凭证登录
-
-获取 Client ID（AppKey）和 Client Secret（AppSecret）后，可通过 CLI 参数指定：
+1. [Open Platform Console](https://open-dev.dingtalk.com/fe/app#/corp/app) → Create App
+2. Security Settings → Add redirect URLs: `http://127.0.0.1,https://login.dingtalk.com`
+3. Publish the app
+4. Login:
 
 ```bash
 dws auth login --client-id <your-app-key> --client-secret <your-app-secret>
 ```
 
-或者通过环境变量设置：
+Credentials are securely persisted after first login (Keychain). Subsequent runs auto-refresh tokens.
+
+</details>
+
+## Quick Start
 
 ```bash
-export DWS_CLIENT_ID=<your-app-key>
-export DWS_CLIENT_SECRET=<your-app-secret>
-dws auth login
+dws contact user search --keyword "engineering"     # search contacts
+dws calendar event list                            # list calendar events
+dws todo task create --title "Quarterly report" --executors "<your-userId>"   # create a todo (replace <your-userId>)
+dws todo task list --dry-run                       # preview without executing
 ```
 
-> [!NOTE]
-> CLI 参数优先级高于环境变量。这些凭证用于钉钉的 OAuth 设备流认证。
+## Using with Agents
 
-### Token 加密
+dws is designed as an AI-native CLI. Complete [Installation](#installation) and [Getting Started](#getting-started) first, then configure your agent:
 
-Token 使用 **PBKDF2（600,000 次迭代）+ AES-256-GCM** 加密存储，密钥由您的设备 MAC 地址生成。
-
-## 快速开始
+### Agent Invocation Patterns
 
 ```bash
-dws auth login                                    # 钉钉身份认证
-dws contact user search --keyword "悟空"           # 搜索联系人
-dws calendar event list                            # 列出日历事件
-dws todo task create --title "准备季度汇报材料" --executors "<userId>"   # 创建待办
+# Use --yes to skip confirmation prompts (required for agents)
+dws todo task create --title "Review PR" --executors "<your-userId>" --yes
+
+# Use --dry-run to preview operations (safe execution)
+dws contact user search --keyword "engineering" --dry-run
+
+# Use --jq to extract precisely (save tokens)
+dws contact user get-self --jq '.result[0].orgEmployeeModel | {name: .orgUserName, dept: .depts[0].deptName, userId}'
 ```
 
-## AI Agent Skills
+### Schema Discovery
 
-仓库为每个支持的钉钉产品提供 agent skills（`SKILL.md` 文件）。
-
-Skills 由[安装](#安装)脚本自动安装。如需单独将 skills 安装到现有项目：
+Agents don't need pre-built knowledge of every command. Use `dws schema` to dynamically discover capabilities:
 
 ```bash
-# macOS / Linux — 仅将 skills 安装到当前项目
+# Step 1: Discover all available products
+dws schema --jq '.products[] | {id, tool_count: (.tools | length)}'
+
+# Step 2: Inspect target tool's parameter schema
+dws schema aitable.query_records --jq '.tool.parameters'
+
+# Step 3: Construct the correct call
+dws aitable record query --base-id BASE_ID --table-id TABLE_ID --limit 10
+```
+
+### Agent Skills
+
+The repo ships a complete Agent Skill system (`skills/`). After installing, AI tools like Claude Code / Cursor can operate DingTalk directly through natural language:
+
+```bash
+# Install skills into current project
 curl -fsSL https://raw.githubusercontent.com/DingTalk-Real-AI/dingtalk-workspace-cli/main/scripts/install-skills.sh | sh
 ```
 
-一键安装器（`install.sh`）将 skills 安装到 `~/.agents/skills/dws`（主目录）。
-当您想要为特定项目仓库添加 skills 时，请使用 `install-skills.sh`，它会安装到 `./.agents/skills/dws`（当前工作目录）。
+> `install.sh` installs to `$HOME/.agents/skills/dws` (global); `install-skills.sh` installs to `./.agents/skills/dws` (current project).
 
-> [!NOTE]
-> **主目录 vs. 项目 skills**：`install.sh` 将 skills 放在 `$HOME/.agents/skills/dws`。`install-skills.sh` 安装到**当前工作目录**（`./.agents/skills/dws`），适用于为特定项目仓库添加 skills。

-## 架构设计
+</details>
 
-`dws` 使用 **发现驱动的管道** — 不硬编码任何产品命令：
+<h2 id="security-by-design">Security by Design</h2>
 
-```
-Market Registry ──► Discovery ──► IR (规范化目录) ──► CLI (Cobra) ──► Transport (MCP JSON-RPC)
-      │                 │
-      ▼                 ▼
-  mcp.dingtalk.com   缓存（TTL + 过期降级）
-```
+`dws` treats security as a first-class architectural concern, not an afterthought. **Credentials never touch disk, tokens never leave trusted domains, permissions never exceed grants, operations never escape audit** — every API call must pass through DingTalk Open Platform's authentication and audit chain, no exceptions.
 
-1. **Market** — 从 `mcp.dingtalk.com` 获取 MCP 服务注册表
-2. **Discovery** — 解析服务运行时能力，支持磁盘缓存和过期降级保证离线可用
-3. **IR** — 将服务规范化为统一的产品/工具目录
-4. **CLI** — 将目录挂载到 Cobra 命令树，映射 flag 到 MCP 输入参数
-5. **Transport** — 执行 MCP JSON-RPC 调用，支持重试、认证注入和响应大小限制
+<details>
+<summary><strong>For Developers</strong></summary>
 
-使用 `-f json` 时，所有输出 — 成功、错误和元数据 — 都是结构化 JSON。
+| Mechanism | Details |
+|-----------|----------|
+| **Encrypted token storage** | **PBKDF2 + AES-256-GCM** encryption, keyed by device physical MAC address; cross-platform Keychain/DPAPI integration provides additional protection — tokens cannot be decrypted on another machine |
+| **Input security** | Path traversal protection (symlink resolution + working directory containment), CRLF injection blocking, Unicode visual spoofing filtering — prevents AI Agents from being tricked by malicious instructions |
+| **Domain allowlist** | `DWS_TRUSTED_DOMAINS` defaults to `*.dingtalk.com`; bearer tokens are never sent to non-allowlisted domains |
+| **HTTPS enforced** | All requests require TLS; HTTP only permitted for loopback during development |
+| **Dry-run preview** | `--dry-run` shows call parameters without executing, preventing accidental mutations |
+| **Zero credential persistence** | Client ID / Secret used in memory only — never written to config files or logs |

-<h2 id="why-dws">Why dws?</h2>
-
-**For humans** — stop writing raw API calls. `dws` gives you `--help` on every resource, `--dry-run` to preview requests, and structured output in table/JSON/raw formats.
-
-**For AI agents** — every response is structured JSON. Pair it with the included agent skills and your LLM can manage DingTalk Workspace without custom tooling.
-
-```bash
-# Search for a contact
-dws contact user search --keyword "Alice"
-
-# Create a todo item
-dws todo task create --title "Prepare quarterly report" --executors "<userId>"
-
-# Preview an operation without executing
-dws todo task list --dry-run
-
-# JSON output for agent consumption
-dws contact user search --keyword "Alice" -f json
-```
-

-## Installation
-
-### One-line install (recommended)
-
-**macOS / Linux:**
-
-```bash
-curl -fsSL https://raw.githubusercontent.com/DingTalk-Real-AI/dingtalk-workspace-cli/main/scripts/install.sh | sh
-```
-
-**Windows (PowerShell):**
-
-```powershell
-irm https://raw.githubusercontent.com/DingTalk-Real-AI/dingtalk-workspace-cli/main/scripts/install.ps1 | iex
-```
-
-> Auto-detects OS and architecture, downloads the pre-built binary from [GitHub Releases](https://github.com/DingTalk-Real-AI/dingtalk-workspace-cli/releases), and installs Agent Skills to `~/.agents/skills/dws` — no Go, Node.js, or other dependencies required. Most AI agents (Claude Code, Cursor, Windsurf, etc.) can discover skills from the `.agents/skills/` directory.
-
-> [!TIP]
-> The binary is installed to `~/.local/bin` by default. If `dws` is not found after installation, add it to your PATH:
-> ```bash
-> export PATH="$HOME/.local/bin:$PATH"
-> ```
-> Add this line to your `~/.bashrc` or `~/.zshrc` to make it permanent.
-
-### Pre-built binary (manual)
-
-Download the latest binary for your platform from [GitHub Releases](https://github.com/DingTalk-Real-AI/dingtalk-workspace-cli/releases).
-
-### Build from source
-
-```bash
-git clone https://github.com/DingTalk-Real-AI/dingtalk-workspace-cli.git
-cd dingtalk-workspace-cli
-make build
-./dws version
-```
-
-This builds the binary only. To also install agent skills into your home directory:
-
-```bash
-sh scripts/install.sh
-```
-
-This detects the local source checkout and installs both the binary and skills without downloading from GitHub.
-
-## Getting Started
-
-### Step 1: Create a DingTalk Application
-
-Go to the [Open Platform App Development Console](https://open-dev.dingtalk.com/fe/app?hash=%23%2Fcorp%2Fapp#/corp/app). Under "Internal Enterprise Apps - DingTalk Apps", click **Create App** in the top right corner to create a new application.
-
-<p align="center">
-  <img src="https://img.alicdn.com/imgextra/i4/O1CN01VIkwvV1a5NQzCIFO0_!!6000000003278-2-tps-2690-1462.png" alt="Create Application" width="600">
-</p>
-
-### Step 2: Configure Redirect URL
-
-After creating the app, go into the app settings and click **Security Settings**. In the "Redirect URL (Callback Settings)" section, enter `http://127.0.0.1` and save.
-
-<p align="center">
-  <img src="https://img.alicdn.com/imgextra/i4/O1CN017xQGWb1ycrAG0uxBO_!!6000000006600-2-tps-2000-1032.png" alt="Configure Redirect URL" width="600">
-</p>
-
-### Step 3: Publish the Application
-
-Click "App Release - Version Management & Release", publish a version to make the app go live.
-
-<p align="center">
-  <img src="https://img.alicdn.com/imgextra/i4/O1CN01WOLZFz244P46B3FPu_!!6000000007337-2-tps-2000-1100.png" alt="Publish Application" width="600">
-</p>
-
-### Step 4: Request Whitelist Access
-
-Refer to the [Co-creation Phase notice](#important) at the top of this page to join the DingTalk DWS co-creation group and complete whitelist configuration.
-
-### Step 5: Login with Credentials
-
-Once you have the AppKey and AppSecret, specify them via CLI flags:
-
-```bash
-dws auth login --client-id <your-app-key> --client-secret <your-app-secret>
-```
-
-Alternatively, set via environment variables:
-
-```bash
-export DWS_CLIENT_ID=<your-app-key>
-export DWS_CLIENT_SECRET=<your-app-secret>
-dws auth login
-```
-
-> [!NOTE]
-> CLI flags take precedence over environment variables. These credentials are used for the OAuth device flow authentication with DingTalk.
-
-### Token Encryption
-
-Tokens are encrypted at rest using **PBKDF2 (600,000 iterations) + AES-256-GCM**, keyed by your device MAC address.
-
-## Quick Start
-
-```bash
-dws auth login                                    # authenticate with DingTalk
-dws contact user search --keyword "Alice"           # search contacts
-dws calendar event list                            # list calendar events
-dws todo task create --title "Prepare quarterly report" --executors "<userId>"   # create a todo
-```
-
-## AI Agent Skills
-
-The repo ships agent skills (`SKILL.md` files) for every supported DingTalk product.
-
-Skills are installed automatically by the [Installation](#installation) scripts. To install skills separately into an existing project:
-
-```bash
-# macOS / Linux — install only skills into the current project
-curl -fsSL https://raw.githubusercontent.com/DingTalk-Real-AI/dingtalk-workspace-cli/main/scripts/install-skills.sh | sh
-```
-
-The one-line installer (`install.sh`) installs skills to `~/.agents/skills/dws` (home directory).
-Use `install-skills.sh` when you want to seed a specific project repository with `./.agents/skills/dws` (current working directory).
-
-> [!NOTE]
-> **Home vs. project skills**: `install.sh` places skills in `$HOME/.agents/skills/dws`. `install-skills.sh` installs into the **current working directory** (`./.agents/skills/dws`), which is useful for seeding a specific project repository.
-
-## Advanced Usage
-
-### Output Formats
-
-All commands support multiple output formats:
-
-```bash
-# Table (default, human-friendly)
-dws contact user search --keyword "Alice" -f table
-
-# JSON (for agents and piping)
-dws contact user search --keyword "Alice" -f json
-
-# Raw API response
-dws contact user search --keyword "Alice" -f raw
-```
-
-### Dry Run
-
-Preview the MCP tool invocation without executing:
-
-```bash
-dws todo task list --dry-run
-```
-
-### Output to File
-
-```bash
-dws contact user search --keyword "Alice" -o result.json
-```
-
-### Shell Completion
-
-```bash
-# Bash
-dws completion bash > /etc/bash_completion.d/dws
-
-# Zsh
-dws completion zsh > "${fpath[1]}/_dws"
-
-# Fish
-dws completion fish > ~/.config/fish/completions/dws.fish
-```
-
-## Environment Variables
-
-Common runtime and development overrides:
-
-| Variable | Purpose |
-|---------|---------|
-| `DWS_CONFIG_DIR` | Overrides the default config directory |
-| `DWS_SERVERS_URL` | Points discovery at a custom server registry endpoint |
-| `DWS_CLIENT_ID` | OAuth client ID (DingTalk AppKey) |
-| `DWS_CLIENT_SECRET` | OAuth client secret (DingTalk AppSecret) |
-| `DWS_TRUSTED_DOMAINS` | Comma-separated list of trusted domains for bearer token injection (default: `*.dingtalk.com`). Set to `*` for development only |
-| `DWS_ALLOW_HTTP_ENDPOINTS` | Set to `1` to allow HTTP (non-TLS) for loopback addresses during development |
-
-## Exit Codes
-
-| Code | Category | Description |
-|------|----------|-------------|
-| 0 | Success | Command completed successfully |
-| 1 | API | MCP tool call or upstream API failure |
-| 2 | Auth | Authentication or authorization failure |
-| 3 | Validation | Invalid input, flags, or parameter schema mismatch |
-| 4 | Discovery | Server discovery, cache, or protocol negotiation failure |
-| 5 | Internal | Unexpected internal error |
-
-When `-f json` is used, error responses include structured payloads with `category`, `reason`, `hint`, and optional `actions` fields for machine consumption.
-
-## Architecture
-
-`dws` uses a **discovery-driven pipeline** — no product commands are hardcoded:
-
-```
-Market Registry ──► Discovery ──► IR (Canonical Catalog) ──► CLI (Cobra) ──► Transport (MCP JSON-RPC)
-      │                 │
-      ▼                 ▼
-  mcp.dingtalk.com   Cache (TTL + stale fallback)
-```
-
-1. **Market** — fetches the MCP server registry from `mcp.dingtalk.com`
-2. **Discovery** — resolves runtime server capabilities with disk cache and stale-fallback for offline resilience
-3. **IR** — normalizes servers into a canonical product/tool catalog
-4. **CLI** — mounts the catalog onto a Cobra command tree, maps flags to MCP input parameters
-5. **Transport** — executes MCP JSON-RPC calls with retries, auth injection, and response size limits
-
-All output — success, errors, and metadata — is structured JSON when using `-f json`.
-
-## Development

+- **为企业管理员而设计** — 零信任架构：OAuth 设备流认证 + 域名白名单 + 权限最小化。**没有一个字节能绕过安全鉴权和审计。**
+
+## 安装
+
+**macOS / Linux：**
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/DingTalk-Real-AI/dingtalk-workspace-cli/main/scripts/install.sh | sh
+```
+
+**Windows（PowerShell）：**
+
+```powershell
+irm https://raw.githubusercontent.com/DingTalk-Real-AI/dingtalk-workspace-cli/main/scripts/install.ps1 | iex
+```
+
+<details>
+<summary>其他安装方式</summary>
+
+**预编译二进制文件**：从 [GitHub Releases](https://github.com/DingTalk-Real-AI/dingtalk-workspace-cli/releases) 下载。
+
+> **macOS 用户注意**：如果提示“无法打开，因为 Apple 无法检查其是否包含恶意软件”，请执行：
+> ```bash
+> xattr -d com.apple.quarantine /path/to/dws
+> ```
+
+**从源码构建**：
+
+```bash
+git clone https://github.com/DingTalk-Real-AI/dingtalk-workspace-cli.git
+cd dingtalk-workspace-cli
+go build -o dws ./cmd       # 编译到当前目录
+cp dws ~/.local/bin/         # 安装到 PATH
+```
+
+> 需要 Go 1.25+。也可以用 `make package` 构建所有平台产物（macOS / Linux / Windows × amd64 / arm64）。
+
+</details>
+
+## 升级
+
+dws 内置自升级能力，直接从 [GitHub Releases](https://github.com/DingTalk-Real-AI/dingtalk-workspace-cli/releases) 拉取更新，支持 SHA256 完整性校验和自动备份。
+
+```bash
+dws upgrade                    # 交互式升级到最新版本
+dws upgrade --check            # 仅检查是否有新版本
+dws upgrade --list             # 列出所有可用版本
+dws upgrade --version v1.0.7   # 升级到指定版本
+dws upgrade --rollback         # 回滚到上一版本
+dws upgrade -y                 # 跳过确认直接升级
+```
+
+<details>
+<summary><strong>工作原理</strong></summary>
+
+升级过程采用两阶段原子流程，确保一致性：
+
+1. **准备阶段** — 将平台对应的二进制文件和技能包下载到临时目录，校验 SHA256 校验和，解压并验证所有文件。任何步骤失败则立即中止，不会修改现有安装。
+2. **执行阶段** — 仅在所有准备工作成功后，替换二进制文件并将技能包安装到所有已检测到的 Agent 目录（`~/.agents/skills/dws`、`~/.claude/skills/dws`、`~/.cursor/skills/dws` 等）。
+
+每次升级前自动备份当前版本，可通过 `dws upgrade --rollback` 随时回滚。
+
+| Flag | 说明 |
+|------|------|
+| `--check` | 仅检查更新，不安装 |
+| `--list` | 列出所有可用版本及更新日志 |
+| `--version` | 升级到指定版本（如 `v1.0.7`） |
+| `--rollback` | 回滚到上一个备份版本 |
+| `--force` | 强制重新安装，即使已是最新版本 |
+| `--skip-skills` | 跳过技能包更新 |
+| `-y` | 跳过确认提示 |
+
+</details>
+
+## 开始使用

+<summary><strong>自建应用模式（CI/CD、ISV 集成）</strong></summary>
+
+企业自主管控场景，可创建自有钉钉应用：
+
+1. [开放平台应用开发后台](https://open-dev.dingtalk.com/fe/app#/corp/app) → 创建应用
+2. 安全设置 → 添加重定向 URL：`http://127.0.0.1,https://login.dingtalk.com`
+3. 发布应用
+4. 登录：
+
+```bash
+dws auth login --client-id <your-app-key> --client-secret <your-app-secret>
+```
+
+首次登录后凭证安全存储（Keychain），后续自动刷新 Token。
+
+</details>
+
+## 快速开始
+
+```bash
+dws contact user search --keyword "悟空"           # 搜索联系人
+dws calendar event list                            # 查看日历日程
+dws todo task create --title "季度汇报" --executors "<your-userId>"   # 创建待办（请替换为真实 userId）
+dws todo task list --dry-run                       # 预览操作但不执行
+```
+
+## 在 Agent 中使用
+
+dws 是为 AI Agent 设计的 CLI 工具。请先完成[安装](#安装)和[开始使用](#开始使用)，然后配置 Agent 环境：
+
+### Agent 调用模式
+
+```bash
+# 使用 --yes 跳过确认提示（Agent 必须）
+dws todo task create --title "Review PR" --executors "<your-userId>" --yes
+
+# 使用 --dry-run 预览操作（安全执行）
+dws contact user search --keyword "张三" --dry-run
+
+# 使用 --jq 精确提取（节省 token）
+dws contact user get-self --jq '.result[0].orgEmployeeModel | {name: .orgUserName, dept: .depts[0].deptName, userId}'
+```
+
+### Schema 发现
+
+Agent 无需预置所有命令知识，通过 `dws schema` 动态发现可用能力：
+
+```bash
+# 第一步：发现所有可用产品
+dws schema --jq '.products[] | {id, tool_count: (.tools | length)}'
+
+# 第二步：查看目标工具的参数结构
+dws schema aitable.query_records --jq '.tool.parameters'
+
+# 第三步：构造正确的调用
+dws aitable record query --base-id BASE_ID --table-id TABLE_ID --limit 10
+```
+
+### Agent Skills
+
+仓库内置完整的 Agent Skill 体系（`skills/`），安装后 Claude Code / Cursor 等 AI 工具可通过自然语言直接操作钉钉：
+
+```bash
+# 安装 skills 到当前项目
+curl -fsSL https://raw.githubusercontent.com/DingTalk-Real-AI/dingtalk-workspace-cli/main/scripts/install-skills.sh | sh
+```
+
+> `install.sh` 安装到 `$HOME/.agents/skills/dws`（全局）；`install-skills.sh` 安装到 `./.agents/skills/dws`（当前项目）。

+
+## 安全设计
+
+`dws` 从架构层面将安全作为一等公民，而非事后补丁。**凭证不落盘、Token 不出域、权限不越界、操作不脱审** — 每一次 API 调用都必须经过钉钉开放平台的鉴权和审计链路，无例外。
+
+<details>
+<summary><strong>开发者安全机制</strong></summary>
+
+| 机制 | 说明 |
+|------|------|
+| **Token 加密存储** | **PBKDF2（600,000 次迭代 + SHA-256）+ AES-256-GCM** 加密，密钥绑定设备物理 MAC 地址；macOS 集成系统 Keychain、Windows 集成 DPAPI 提供额外保护，跨设备无法解密 |
+| **输入安全防护** | 路径遍历防护（符号链接解析 + 工作目录约束）、CRLF 注入拦截、Unicode 视觉欺骗字符过滤，防止 AI Agent 被恶意指令诱导 |
+| **域名白名单** | `DWS_TRUSTED_DOMAINS` 默认仅信任 `*.dingtalk.com`，Bearer Token 不会发送到非白名单域 |
+| **并发安全** | 双层锁机制（进程内 + 跨进程文件锁）保障 Token 刷新原子性，适配高并发 MCP Server 场景 |
+| **数据完整性** | 所有配置写入采用原子操作（temp + fsync + rename），确保进程中断时数据不损坏 |
+| **HTTPS 强制** | 除 loopback 开发调试外，所有请求强制 TLS |
+| **Dry-run 预览** | `--dry-run` 展示调用参数但不执行，防止误操作生产数据 |
+| **凭证零落盘** | Client ID / Secret 仅在内存中使用，不写入配置文件或日志 |
+
+</details>
+
+<details>
+<summary><strong>企业管理员安全机制</strong></summary>
+
+| 机制 | 说明 |
+|------|------|
+| **OAuth 设备流认证** | 用户必须通过管理员授权的钉钉应用认证，未授权应用无法获取 Token |
+| **权限最小化** | CLI 仅能调用管理员授予该应用的 API 权限范围，无法越权 |
+| **白名单准入** | 共创阶段需管理员主动确认开通，后续支持自助审批 |
+| **操作全链路审计** | 每一次数据读写都经过钉钉开放平台 API，企业管理员可在管理后台实时追溯完整调用日志，任何异常操作无处隐藏 |
+
+</details>
+
+<details>
+<summary><strong>ISV / 企业服务商安全机制</strong></summary>
+
+| 机制 | 说明 |
+|------|------|
+| **租户数据隔离** | 以已授权应用身份调用 API，不同租户数据严格隔离 |
+| **Skill 沙箱** | Agent Skills 是 Markdown 文档（`SKILL.md`），仅提供 prompt 描述，不执行任意代码 |
+| **集成链路零盲区** | ISV Skill 与 dws Skill 联调时，每一次 API 调用都强制经过钉钉开放平台鉴权，完整调用链路可追溯，不存在绕过审计的旁路 |
