Summary
Connects your Claude agent to Feishu or Lark (the international version) using OAuth device flow. You call connect, the user scans a QR code or opens a link to authorize in their app, you poll for completion, and done. The skill handles brand selection (feishu.cn for China, larksuite.com internationally), shows both QR and clickable URL options, and reminds you not to auto-poll since device codes expire in five minutes. Disconnect is destructive and requires confirmation. It's the Feishu equivalent of the WeChat and Telegram binding flows, with the main difference being device flow instead of bot tokens or direct QR auth.

📱 Feishu/Lark Binding
Connect / disconnect the user's Feishu (飞书) or Lark account so the agent can chat via the Feishu/Lark app.
The feishu tool stays built-in. This SKILL.md is the reference doc.

Brand selection
| Brand | Region | Domain |
|---|---|---|
feishu | China mainland (中国大陆) | feishu.cn / accounts.feishu.cn |
lark | International | larksuite.com / accounts.larksuite.com |
Ask the user which brand they use. Default to feishu if unclear. Chinese-speaking users almost always use feishu.
Typical binding flow
connect(brand) → user scans QR / opens link → poll(device_code) → done
- Start device flow:
feishu(action="connect", brand="feishu")— returnsverification_uri,device_code, and a QR code image saved to workspace. - Show BOTH options to the user:
- QR code scan: Display the QR code image inline using the
markdown_imagefrom the result (e.g.). The user scans it with their Feishu/Lark app. - Direct link: Show the
verification_urlas a clickable link. The user opens it in their browser, logs in to Feishu/Lark, and confirms.
- QR code scan: Display the QR code image inline using the
- Wait for the user to confirm. Don't auto-poll — let them say "done" / "confirmed" / "已确认" / "scanned" first.
- Poll for completion:
feishu(action="poll", device_code=<from step 1>, brand=<same brand>).status: "done"→ binding complete, congratulate the user.status: "pending"→ ask the user if they've scanned the QR code or opened the link and confirmed.status: "expired"→ the device flow expired (typically 5 minutes). Start over withconnect.
- Confirm to user: "Feishu/Lark connected! You can now chat with your agent on Feishu/Lark."
Actions
| action | required params | purpose |
|---|---|---|
status | — | Current Feishu/Lark app state. Use to check if already connected. |
connect | brand (optional, default "feishu") | Start device flow. Returns verification URL + device_code. |
poll | device_code, brand | Check if user has confirmed authorization. Returns status. |
disconnect | — | Unbind Feishu/Lark app (destructive — confirm with user first). |
Channel-aware QR / link display
| User channel | How to show |
|---|---|
| Web | Include file_path (QR image) in your reply — frontend renders it inline. Also show the link. |
| Telegram | send_to_telegram(file_path=<qr_path>, message_type="photo") + include the link in the caption |
| Show the link only (user can't scan a QR inside WeChat for Feishu) | |
| Feishu | (User is already on Feishu — they don't need to bind. Tell them it's already connected or check status.) |
Key differences from WeChat / Telegram
| Aspect | Feishu/Lark | Telegram | |
|---|---|---|---|
| Auth method | Device flow (URL) | QR code scan | Bot token |
| User action | Open URL + confirm in app | Scan QR + confirm | Create bot via @BotFather |
| Credential | None (device flow handles it) | bot_token (from QR) | bot_token (from BotFather) |
| Brand choice | feishu / lark | N/A | N/A |
Critical rules
- Don't auto-poll after
connect. Wait for user confirmation that they've opened the link and confirmed in Feishu/Lark. Auto-polling wastes API calls. - Device flow expires in ~5 minutes. If
pollreturnsexpired, tell the user and start a newconnect. disconnectis destructive — confirm with the user before calling it. It will stop the Feishu/Lark gateway instance.- Brand matters —
feishuandlarkuse different API domains. Using the wrong brand will fail silently or redirect to the wrong login page. - One app per user — a user can only have one Feishu/Lark app at a time. If they want to switch brands, they must
disconnectfirst, thenconnectwith the new brand.
Troubleshooting
| Symptom | Likely cause | Fix |
|---|---|---|
connect returns error | User already has an active app | Call status first; if active, ask if they want to disconnect and rebind |
poll returns expired | User took too long to confirm | Start a new connect |
poll returns pending repeatedly | User hasn't opened the URL yet | Remind them to open the verification URL |
| User says "I can't find the link" | URL was in a previous message | Re-run connect to get a fresh URL |
