Why dws?

- **For humans** — `--help` for usage, `--dry-run` to preview requests, `-f table/json/raw` for output formats. - **For AI agents** — structured JSON responses + built-in Agent Skills, ready out of the box. - **For enterprise admins** — zero-trust architecture: OAuth device-flow auth + domain allowlisting + least-privilege scoping. **Not a single byte can bypass authentication and audit.** ## Installation **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 ```
Skill mode: mono vs multi The installer ships skills in one of two layouts. CLI commands (`dws aitable ...`, `dws calendar ...`) are identical in both modes — only the agent-side skill layout differs. | Mode | What gets installed | Best for | |------|----------------------|----------| | **mono** (stable, default) | One `dws` skill covering all products | Cross-product workflows; single entry point | | **multi** 🧪 **EXPERIMENTAL** | 18 per-product skills (`dingtalk-aitable`, `dingtalk-calendar`, `dingtalk-chat`, ...) | Single-product tasks; smaller context per call | > 🧪 **`multi` is currently EXPERIMENTAL / preview.** 18 product-scoped skills all pass the dispatch verifier, but interface, naming and cross-skill references may change in future releases. For production / shared environments, prefer `mono`. File issues if you hit problems. How to pick: - **Quick install** (one-liner above): non-interactive, installs `mono`. - **TTY install** (download then run): `curl -O .../install.sh && bash install.sh` — prompts `1) mono 2) multi` (default 1). - **Override via env**: `DWS_SKILL_MODE=multi curl -fsSL ... | sh`. - **Switch later**: `dws skill setup --mode multi` (or `--mode mono`) — re-run any time.
Other install methods **npm** (requires Node.js (npm/npx)): ```bash npm install -g dingtalk-workspace-cli ``` **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 > xattr -d com.apple.quarantine /path/to/dws > ``` **Build from source**: ```bash git clone https://github.com/DingTalk-Real-AI/dingtalk-workspace-cli.git cd dingtalk-workspace-cli go build -o dws ./cmd # build to current directory cp dws ~/.local/bin/ # install to PATH ``` > Requires Go 1.25+. Use `make package` to cross-compile for all platforms (macOS / Linux / Windows x amd64 / arm64).
## China mirror For users in mainland China, the following channels avoid GitHub network issues. By default (without setting these environment variables) the installer pulls from GitHub. **1. Install script + pre-built binary (Gitee mirror):** Repository mirror: `https://gitee.com/DingTalk-Real-AI/dingtalk-workspace-cli` ```bash DWS_GITEE_REPO=DingTalk-Real-AI/dingtalk-workspace-cli curl -fsSL https://gitee.com/DingTalk-Real-AI/dingtalk-workspace-cli/raw/main/scripts/install.sh | sh ``` > With `DWS_GITEE_REPO` set, the installer resolves the latest version and every release asset (binary, checksums, skills) from the Gitee API instead of GitHub. If it is unset, installation defaults to GitHub. **2. npm package (npmmirror mirror):** ```bash npm install -g dingtalk-workspace-cli --registry=https://registry.npmmirror.com ``` > npmmirror automatically syncs public packages from the public npm registry, so this works directly in China. **3. Skills only (Gitee mirror):** ```bash DWS_GITEE_REPO=DingTalk-Real-AI/dingtalk-workspace-cli curl -fsSL https://gitee.com/DingTalk-Real-AI/dingtalk-workspace-cli/raw/main/scripts/install-skills.sh | sh ``` > With `DWS_GITEE_REPO` set, `install-skills.sh` resolves the version and skills package from Gitee; it also auto-falls back to the Gitee mirror when GitHub is unreachable. ## Upgrade > Requires **v1.0.7** or later. For earlier versions, please re-run the [install script](#installation) to 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 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 ```
How it works The upgrade process follows a two-phase atomic flow to ensure consistency: 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.). 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 |
## 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`.
Organization hasn't enabled CLI access? 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`

Apply for Access

Admin: Enable CLI access for your organization Go to [Developer Platform](https://open-dev.dingtalk.com) → "CLI Access Management" → Enable.

CLI Access Management

Custom App mode (CI/CD, ISV integration) For enterprise-managed scenarios, create your own DingTalk app: 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 --client-secret ``` Credentials are securely persisted after first login (Keychain). Subsequent runs auto-refresh tokens.
Multiple organizations (profiles) `dws` can stay logged in to several DingTalk organizations at once. Each organization is one **profile**; the current profile decides which org a command runs against (credentials are stored per organization). ```bash dws auth login # log in to another org → adds a profile (first login becomes the primary) dws profile list # list logged-in orgs (primary / current marker, status) dws profile switch # switch the default org (use - to toggle back to the previous one) dws --profile contact user search --query "..." # run one command against a specific org, without changing the default ``` Cross-org reads are orchestrated by the agent rather than a built-in `--all-orgs`: list the profiles, run the query per org with `--profile`, then merge. Writes default to the current org only — confirm the target org before writing across orgs.
Migrate auth between Linux sandboxes Copying only `~/.dws/app.json` does not carry the refresh token; access tokens expire after ~2 hours. Use the official export/import flow: ```bash # Sandbox A (already logged in) dws auth export -o /tmp/dws-auth.tar.gz # Or for copy/paste: dws auth export --base64 -o /tmp/dws-auth.b64 # Sandbox B dws auth import -i /tmp/dws-auth.tar.gz # Or: dws auth import -i /tmp/dws-auth.b64 --base64 dws auth status # confirm "Refresh Token: valid" ``` The bundle includes the encrypted keychain under `~/.local/share/dws-cli` (with `auth-token.enc` and `dek`) plus required `~/.dws` config files.
## Quick Start ```bash dws contact user search --query "engineering" # search contacts dws calendar event list # list today's calendar events dws doc search --query "quarterly" # search DingTalk Docs dws minutes list mine # list AI meeting notes I created dws drive list # list DingTalk drive files dws todo task create --title "Quarterly report" --executors "" # create a todo (replace ) dws todo task list --dry-run # preview without executing ``` > **Full command list**: [`docs/command-index.md`](./docs/command-index.md) — all commands with descriptions and when-to-use guidance. ## Using with Agents dws is designed as an AI-native CLI. Complete [Installation](#installation) and [Getting Started](#getting-started) first, then configure your agent: ### Agent Invocation Patterns ```bash # Use --yes to skip confirmation prompts (required for agents) dws todo task create --title "Review PR" --executors "" --yes # Use --dry-run to preview operations (safe execution) dws contact user search --query "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}' ``` ### Schema Discovery Agents don't need pre-built knowledge of every command. Use `dws schema` to dynamically discover capabilities: ```bash # 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' # Optional: inspect DingTalk authorization metadata for PAT planning dws schema aitable.query_records --jq '.tool.auth' # 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 under `skills/`, now organized into two layouts: - `skills/mono/` — single-skill layout (one `SKILL.md` + `references/products/`), recommended default. - `skills/multi/` — per-product skills (`dingtalk-aitable/`, `dingtalk-calendar/`, `dingtalk-chat/`, ... 20 products in total), each with its own `SKILL.md`. 🧪 **EXPERIMENTAL / preview — see banner in each multi `SKILL.md` for caveats.** After installing, AI tools like Claude Code / Cursor can operate DingTalk directly through natural language: ```bash # Install skills into current project (defaults to mono) curl -fsSL https://raw.githubusercontent.com/DingTalk-Real-AI/dingtalk-workspace-cli/main/scripts/install-skills.sh | sh ``` > `install.sh` installs to `$HOME/.agents/skills/dws` (global); `install-skills.sh` installs to `./.agents/skills/dws` (current project). > > China users: prefix `DWS_GITEE_REPO` to use the Gitee mirror — see [China mirror](#china-mirror). **Switching or re-installing with `dws skill setup`:** ```bash # Interactive: prompts for mode + target agents dws skill setup # Install mono skill to every detected agent home (claude / cursor / codex / opencode / qoder) dws skill setup --mode mono --target all --yes # Install multi skills to a single agent home dws skill setup --mode multi --target cursor --yes # Point at a local source tree (e.g. a fork or work-in-progress) DWS_SKILL_SOURCE=/path/to/skills dws skill setup --mode multi ``` | Flag | Values | Description | |------|--------|-------------| | `--mode` | `mono` \| `multi` | Skill layout; defaults to interactive prompt | | `--target` | `all` \| `claude` \| `cursor` \| `codex` \| `opencode` \| `qoder` | Where to install; `all` covers every detected agent home | | `--source` | path | Local source directory (overrides bundled skills) | | `--yes` | — | Skip confirmation prompts | Env vars: `DWS_SKILL_MODE=mono|multi` (also honored by `install.sh` / `install.ps1`), `DWS_SKILL_SOURCE=`. **What's included (mono layout):** | Component | Path | Description | |-----------|------|-------------| | Master Skill | `skills/mono/SKILL.md` | Intent routing, decision tree, safety rules, error handling | | Product references | `skills/mono/references/products/*.md` | Per-product command reference (aitable, chat, calendar, etc.) | | Intent guide | `skills/mono/references/intent-guide.md` | Disambiguation for confusing scenarios (e.g. report vs todo) | | Global reference | `skills/mono/references/global-reference.md` | Auth, output formats, global flags | | Error codes | `skills/mono/references/error-codes.md` | Error codes + debugging workflows | | Recovery guide | `skills/mono/references/recovery-guide.md` | `RECOVERY_EVENT_ID` handling | | Ready-made scripts | `skills/mono/scripts/*.py` | 13 batch operation scripts (see below) |
Ready-made scripts — 13 Python scripts for common multi-step workflows | Script | Description | |--------|-------------| | `calendar_schedule_meeting.py` | Create event + add participants + find & book available meeting room | | `calendar_free_slot_finder.py` | Find common free slots across multiple people, recommend best meeting time | | `calendar_today_agenda.py` | View today/tomorrow/this week's schedule | | `import_records.py` | Batch import records from CSV/JSON into AITable | | `bulk_add_fields.py` | Batch add fields to an AITable data table | | `upload_attachment.py` | Upload attachment to AITable attachment field | | `todo_batch_create.py` | Batch create todos from JSON (with priority, due date, executors) | | `todo_daily_summary.py` | Summarize today/this week's incomplete todos | | `todo_overdue_check.py` | Scan overdue todos and output overdue list | | `contact_dept_members.py` | Search department by name and list all members | | `attendance_my_record.py` | View my attendance records for today/this week/specific date | | `attendance_team_shift.py` | Query team shift schedules and attendance statistics | | `report_inbox_today.py` | View today's received reports with details |
**ISV Integration**: Author your own Agent Skills and orchestrate them with dws skills for cross-product workflows: **ISV Skill → dws Skill → DingTalk Open Platform API (enforced auth + full audit)**. ## Features
Raw API Access — call any DingTalk OpenAPI directly `dws api` lets you call any DingTalk OpenAPI without an SDK. Tokens are automatically acquired and refreshed. > **Prerequisite**: Must login with your own app credentials (see [Custom App mode](#getting-started)). Encrypted tokens from MCP default-credential login are not supported for raw API calls. ```bash # Login (first time only) dws auth login --client-id --client-secret # === api.dingtalk.com === # List all enterprise apps dws api GET /v1.0/microApp/allApps # Search users (POST + JSON body) dws api POST /v1.0/contact/users/search \ --data '{"queryWord":"engineering","offset":0,"size":10}' # === oapi.dingtalk.com === # Get user details (use --base-url to specify domain) dws api POST /topapi/v2/user/get \ --base-url https://oapi.dingtalk.com \ --data '{"userid":""}' # Or use the full URL directly dws api POST https://oapi.dingtalk.com/topapi/v2/user/get \ --data '{"userid":""}' # === General === dws api GET /v1.0/microApp/allApps --page-all # auto-paginate dws api GET /v1.0/microApp/allApps --dry-run # preview request dws api GET /v1.0/microApp/allApps --jq '.agentId' # jq filtering ``` | Feature | Details | |---------|----------| | Dual-form auto-detection | Automatically selects api.dingtalk.com (header auth) or oapi.dingtalk.com (query-param auth) based on URL | | Automatic token management | App-level accessToken is fetched on first call, cached while valid, auto-refreshed on expiry | | Domain allowlist | Only `api.dingtalk.com` and `oapi.dingtalk.com` permitted — prevents token leakage | | Auto-pagination | `--page-all` iterates all pages. `--page-limit` caps the maximum (default 10, set to 0 for unlimited, hard cap at 500 to prevent infinite loops) |
Smart Input Correction — auto-corrects common AI model parameter mistakes Built-in pipeline engine that normalizes flag names, splits sticky arguments, and fuzzy-matches typos: ```bash # Naming convention auto-conversion (camelCase / snake_case / UPPER -> kebab-case) dws aitable record query --baseId BASE_ID --tableId TABLE_ID # auto-corrected to --base-id --table-id # Sticky argument splitting dws contact user search --query "engineering" --timeout30 # auto-split to --timeout 30 # Fuzzy flag name matching dws aitable record query --base-id BASE_ID --tabel-id TABLE_ID # --tabel-id -> --table-id # Value normalization (boolean / number / date / enum) # "yes" -> true, "1,000" -> 1000, "2024/03/29" -> "2024-03-29", "ACTIVE" -> "active" ``` | Agent Output | dws Auto-Corrects To | |-----------|--------------| | `--userId` | `--user-id` | | `--limit100` | `--limit 100` | | `--tabel-id` | `--table-id` | | `--USER-ID` | `--user-id` | | `--user_name` | `--user-name` |
jq Filtering & Field Selection — fine-grained output control to reduce token consumption ```bash # Built-in jq expressions dws aitable record query --base-id BASE_ID --table-id TABLE_ID --jq '.invocation.params' dws schema --jq '.products[] | {id, tools: (.tools | length)}' # Return only specific fields dws aitable record query --base-id BASE_ID --table-id TABLE_ID --fields invocation,response ```
Schema Introspection — query parameter schemas before making calls ```bash dws schema # list all products and tools dws schema aitable.query_records # view parameter schema dws schema aitable.query_records --jq '.tool.required' # view required fields dws schema aitable.query_records --jq '.tool.auth' # view authorization metadata dws schema --jq '.products[].id' # extract all product IDs ```
Pipe & File Input — read flag values from files or stdin ```bash # Read message body from a file dws chat message send-by-bot --robot-code BOT_CODE --group GROUP_ID \ --title "Weekly Report" --text @report.md # Pipe content via stdin cat report.md | dws chat message send-by-bot --robot-code BOT_CODE --group GROUP_ID \ --title "Weekly Report" # Read from stdin explicitly dws chat message send-by-bot --robot-code BOT_CODE --group GROUP_ID \ --title "Weekly Report" --text @- ``` > **Note**: `@` is treated as the `@` file-injection prefix only when the next character is an ASCII path-shaped character (`A-Z` / `a-z` / `0-9` / `.` / `/` / `~` / `_` / `-`), or `@-` for stdin. Chat-bot payloads like `--text "@所有人 周报"` or `--text "@张三 看一下"` pass through unchanged, so literal mentions reach the API as-is.
## DingTalk bot — connect a robot to your local AI `dws dev connect` bridges a DingTalk robot to a local AI CLI (Claude Code / Codex / opencode / Qoder / Gemini, or any tool via `--agent-cmd`): @-mention the bot in a chat and it answers using your local agent, keeping per-conversation multi-turn memory. ```bash dws dev connect --channel auto --unified-app-id ``` > `--unified-app-id` resolves `clientSecret` at runtime via `dev app credentials get`, > so the secret never appears in argv (`ps` / journald / shell history). The > legacy `--robot-client-id --robot-client-secret ` still works but > the CLI will warn you. In-chat **session commands** (send the bare command as the whole message — no agent turn, no tokens): | Command | Effect | |---------|--------| | `/new` (aliases `/start`, `/reset`) | Start a fresh session; the previous one is left intact (resumable where the agent supports it) | | `/clear` | Wipe the current session — disposed through the agent's real session op (opencode issues `DELETE /session/:id`); channels whose agent exposes no delete primitive fall back to a reset | See [`docs/robot-quickstart.md`](./docs/robot-quickstart.md) for the full 4-step walkthrough (install → create robot → connect → add to a group). ## Key Services | Service | Command | Capabilities | |---------|---------|--------------| | Contact | `contact` | Look up users by name / mobile / job-number, departments, labels & roles, roster profiles & dismissals | | Chat / IM | `chat` (`im`) | Send / reply / search messages, group & member management, bot & webhook messaging, reactions, recall | | Calendar | `calendar` | Events CRUD, attendees, meeting rooms, free/busy & time suggestions | | Todo | `todo` | Create / list / update / complete tasks and comments | | Approval | `oa` | Approve / reject / revoke / transfer; query pending / initiated / CC instances and forms | | Attendance | `attendance` | Clock-in records, shifts, summaries, group rules (read-only) | | Ding | `ding` | Send / recall DING messages | | Report | `report` | Create / submit logs, inbox & outbox, templates, statistics | | AI Tables | `aitable` | Bases / tables / records / fields / views, permissions & roles, automation, charts & dashboards, import / export | | Doc | `doc` | Search / read / write docs, block-level editing, comments, permissions, media, up / download | | Drive | `drive` | List / search / download, folders, upload, copy / move / rename, permissions | | Minutes | `minutes` | AI meeting notes: list, summary / keywords / transcription / todos, mind map, speakers, tags | | Mail | `mail` | Mailboxes, KQL search, read / send, drafts, folders, templates, contacts | | Sheet | `sheet` | Online spreadsheets: worksheet & range read / write, filters, conditional format, images, CSV | | Wiki | `wiki` | Knowledge bases: spaces, members, node tree, docs & files | | DevDoc | `devdoc` | Search the Open Platform docs and diagnose API errors | | AI Search | `aisearch` | Enterprise people search by name / dept / role / duty / supervisor / phone / job-number | | Live | `live` | List my live streams | | Raw API | `api` | Call any DingTalk OpenAPI directly, with managed app-level token | > Full command listing with usage scenarios: [`docs/command-index.md`](./docs/command-index.md). Run `dws --help` for the top-level tree, or `dws --help` for any service's subcommands. > **Note on `chat bot`**: bot capabilities (`send-by-bot` / `recall-by-bot` / `add-bot` / `send-by-webhook` / bot search) are merged into the relevant `chat` subtrees (e.g. `dws chat message send-by-bot`, `dws chat group members add-bot`) so the agent-facing command surface stays flat and discoverable. There is no longer a separate top-level `bot` product.
Coming soon - `conference` (video meetings) - Multi-skill mode (experimental) — per-product skills under `skills/multi/`; opt in via `dws skill setup --mode multi`

Security by Design

`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.
For Developers | 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 |
For Enterprise Admins | Mechanism | Details | |-----------|---------| | **OAuth device-flow auth** | Users must authenticate through an admin-authorized DingTalk application | | **Least-privilege scoping** | CLI can only invoke APIs granted to the application — no privilege escalation | | **Allowlist gating** | Admin confirmation required during co-creation phase; self-service approval planned | | **Full-chain audit** | Every data read/write passes through the DingTalk Open Platform API — enterprise admins can trace complete call logs in real time; no anomalous operation can hide |
For ISVs | Mechanism | Details | |-----------|---------| | **Tenant data isolation** | Operates under authorized app identity; cross-tenant access is impossible | | **Skill sandbox** | Agent Skills are Markdown documents (`SKILL.md`) — prompt descriptions only, no arbitrary code execution | | **Zero blind spots** | Every API call during ISV–dws skill orchestration is forced through DingTalk Open Platform authentication — full call chain is traceable with no bypass path |
