LINE Chat for Official Account

Operate LINE Official Account Manager (chat.line.biz) via browser automation. Use when asked to check LINE messages, reply to LINE customers, or manage LINE OA chat interface.

LINE Official Account Manager

⚠️ CRITICAL: Always use profile:"openclaw" (isolated browser) for all browser actions. Never use Chrome relay. Keep the same targetId across operations to avoid losing the tab.

⚠️ CONTEXT Management:

• Snapshot results are large. Do NOT repeat them in thinking.
• Extract needed info and process immediately. Do not re-describe the entire snapshot.
• Preferred approach: Use snapshot refs:"aria" compact:true to find element refs, then act + click/type with ref.
• Avoid: Hard-coded evaluate with textContent.includes() — unreliable due to DOM timing and structure variations.

⚠️ AUTO-LOGIN SCRIPTS:

• auto-login.mjs is a reference implementation (not directly executable by agents)
• login-flow.md is the agent-executable version (use this for automation)
• Why separate? Agents use browser tool calls, not Node module imports

Configuration

Before first use, check if config.json exists:

text

read file_path:"skills/line-oa/config.json"

⚠️ PATH RULE: Always use workspace-relative paths starting from skills/line-oa/. Never use ../ or absolute paths starting with /.

If missing, help the user run the following command to start the setup wizard:

bash

cd skills/line-oa
node scripts/setup.js

Enter LINE OA Manager

This is the first step for all operations below.

1. Check and start browser service:

   text

   browser action:"status"
   

   If "running": false, start the browser service:

   text

   browser action:"start" profile:"openclaw"
   

   Wait 2-3 seconds for the service to initialize.

2. Read config to get chatUrl:

   text

   read file_path:"skills/line-oa/config.json"
   

   Extract chatUrl from the JSON (e.g., https://chat.line.biz/U1234567890abcdef1234567890abcdef/).

3. Open browser:

   text

   browser action:"open" profile:"openclaw" targetUrl:"<chatUrl>"
   

   Capture targetId and url from response.

4. Wait for page load:

   text

   browser action:"act" profile:"openclaw" targetId:"<targetId>" request:{"kind":"wait","timeMs":2000}
   

5. Check current URL:

   text

   browser action:"act" profile:"openclaw" targetId:"<targetId>" request:{"kind":"evaluate","fn":"function(){return window.location.href;}"}
   

   Key result: If the current URL matches chatUrl, you have successfully logged in! Go to step 5, else proceed to troubleshooting.

   Troubleshooting

   If you see the login page (the URL redirects to account.line.biz), use these automation scripts:

   a. Click LINE Account button:

   text

   read file_path:"skills/line-oa/scripts/click-line-account.js"
   

   Execute the script directly:

   text

   browser action:"act" profile:"openclaw" targetId:"<targetId>" request:{"kind":"evaluate","fn":"<script_content>"}
   

   Wait 2 seconds.

   b. Click Login button:

   text

   read file_path:"skills/line-oa/scripts/click-login.js"
   

   Execute the script directly:

   text

   browser action:"act" profile:"openclaw" targetId:"<targetId>" request:{"kind":"evaluate","fn":"<script_content>"}
   

   Wait 3 seconds.

   c. Reload chatUrl:

   text

   browser action:"navigate" profile:"openclaw" targetId:"<targetId>" targetUrl:"<chatUrl>"
   

   Wait 2 seconds, then take snapshot to verify left-side chat list is visible.

   After Check

6. Proceed with the user's other requests.

7. Clean Up Browser Tabs:

   a. Open a blank tab:

   text

   browser action:"open" profile:"openclaw" targetUrl:"about:blank"
   

   b. Get all tabs:

   text

   browser action:"tabs" profile:"openclaw"
   

   c. Close all tabs except the newest one (about:blank):

   text

   browser action:"close" profile:"openclaw" targetId:"<your_targetId>"
   

   Important: Always clean up tabs after all operations to prevent resource accumulation. The blank tab keeps the browser service running for faster next use.

Quick Check (for cron / automated checks)

Complete flow: login → list chats → report. Follow these steps exactly.

1. Read config: read file_path:"skills/line-oa/config.json" → get chatUrl
2. Open browser: browser action:"open" profile:"openclaw" targetUrl:<chatUrl> → get targetId
3. Wait: browser action:"act" profile:"openclaw" targetId:<targetId> request:{"kind":"wait","timeMs":3000}
4. Check URL: browser action:"act" profile:"openclaw" targetId:<targetId> request:{"kind":"evaluate","fn":"function(){return window.location.href;}"}
   • If URL contains account.line.biz → go to Troubleshooting section below to login, then come back
   • If URL contains chat.line.biz → continue
5. Run this one-liner script as-is, do not modify:

   text

   browser action:"act" profile:"openclaw" targetId:<targetId> request:{"kind":"evaluate","fn":"(function(){var r=document.querySelectorAll('.list-group-item-chat');return Array.from(r).map(function(e){var h=e.querySelector('h6');var p=e.querySelector('.text-muted.small');var pt=p?p.textContent.trim():'';var ms=e.querySelectorAll('.text-muted');var t='';for(var i=0;i<ms.length;i++){var v=ms[i].textContent.trim();if(v&&v.length<20&&v!==pt)t=v;}var d=e.querySelector('span.badge.badge-pin');var u=!!d&&getComputedStyle(d).display!=='none';return{name:h?h.textContent.trim():'',time:t,lastMsg:pt.substring(0,100),unread:u};}).filter(function(i){return i.name;});})()"}
   

   ⚠️ CHECKPOINT: Did you actually call the browser tool above? If you only thought about it but didn't call it, STOP and call it NOW. You MUST see a tool result before continuing.
6. Report: take the first 5 items, format each as: <name> (<time>) <lastMsg> [未讀] or [已讀] based on unread field. If empty array, say "目前沒有聊天記錄".
7. Clean up: open about:blank, list all tabs, close everything except about:blank.

Check LINE Messages

Extracts all chats from the left-side chat list with unread status. Does NOT require clicking into each chat.

Prerequisites: You must be logged in and on the chat list page (see Login section Step 5 for verification).

Steps

1. Read the script content:

   text

   read file_path:"skills/line-oa/scripts/list-chats.js"
   

2. Run the script via browser evaluate:

   Pass the script content directly as the fn parameter:

   text

   browser action:"act" profile:"openclaw" targetId:"<your_targetId>" request:{"kind":"evaluate","fn":"<script_content>"}
   

3. The script returns a JSON array of all chat items with structure:

   text

   [{ name: string, time: string, lastMsg: string, unread: boolean }]
   

   • name: customer display name
   • time: timestamp (e.g., "21:32", "Yesterday", "Friday")
   • lastMsg: last message preview (~100 chars)
   • unread: true if green dot present, false otherwise

4. Get URLs for unread chats (optional but recommended for faster follow-up):

   For each unread chat, click into it to get the direct URL, then return to list:

   text

   browser action:"act" profile:"openclaw" targetId:"<your_targetId>" request:{"kind":"evaluate","fn":"function(){const items=document.querySelectorAll('.list-group-item-chat');const target=Array.from(items).find(el=>{const h6=el.querySelector('h6');return h6&&h6.textContent.includes('<customer_name>');});if(target){const link=target.querySelector('a.d-flex');if(link){link.click();return {clicked:true};}return {linkNotFound:true};}return {itemNotFound:true};}"}
   

   Wait 500ms, then get the URL:

   text

   browser action:"act" profile:"openclaw" targetId:"<your_targetId>" request:{"kind":"evaluate","fn":"function(){return window.location.href;}"}
   

   Navigate back to list:

   text

   browser action:"navigate" profile:"openclaw" targetId:"<your_targetId>" targetUrl:"<chatUrl>"
   

   Wait 1 second before processing next unread chat.

   Result: Store the chat URL (e.g., https://chat.line.biz/U1234567890abcdef1234567890abcdef/chat/U803dc04f...) alongside the chat info for faster access later.

How to Report Results

• If unread: true exists: List each unread chat with name, time, preview, and URL (if obtained)
• If no unread: Say "No unread messages at this time"

Notes

• Unread indicator: span.badge.badge-pin inside each chat list item (green dot)
• Limitation: lastMsg shows the last message in the thread, which may be an auto-response rather than the customer's original message
• Chat URLs: Getting URLs requires clicking each chat. Do this for unread chats to enable faster replies later.
• To read full messages: See "View Specific Messages" section below

View Specific Messages

Opens any chat (read or unread) and displays its messages. Works for viewing message history, checking context, or preparing to reply.

Prerequisites: You must be logged in and on the chat list page. You should know the customer name (from list-chats.js or user request).

Steps

1. Find and click the chat item to open messages:

   Use evaluate to find the chat item by name (more reliable than snapshot for dynamic chat list):

   text

   browser action:"act" profile:"openclaw" targetId:"<your_targetId>" request:{"kind":"evaluate","fn":"function(){const items=document.querySelectorAll('.list-group-item-chat');const target=Array.from(items).find(el=>{const h6=el.querySelector('h6');return h6&&h6.textContent.includes('<customer_name>');});if(target){const link=target.querySelector('a.d-flex');if(link){link.click();return {clicked:true};}return {linkNotFound:true};}return {itemNotFound:true};}"}
   

   Replace <customer_name> with the actual customer name.

2. Wait for messages panel to load:

   text

   browser action:"act" profile:"openclaw" targetId:"<your_targetId>" request:{"kind":"wait","timeMs":2000}
   

3. Take a screenshot to view the messages:

   text

   browser action:"screenshot" profile:"openclaw" targetId:"<your_targetId>"
   

   The screenshot will show:

   • Recent messages in the chat (right panel)
   • Customer info and tags (far right panel)
   • Auto-response status banner (if active)

4. Optional: Read recent messages programmatically

   If you need structured message data instead of a screenshot, read and run this script:

   text

   read file_path:"skills/line-oa/scripts/read-messages.js"
   

   Execute:

   text

   browser action:"act" profile:"openclaw" targetId:"<your_targetId>" request:{"kind":"evaluate","fn":"<script_content>"}
   

   Returns an array of recent messages with:

   • time: timestamp
   • text: message content
   • isCustomer: true if from customer, false if from you
   • hasImage: true if message contains an image

Navigation Tips

To scroll to earlier messages:

• The messages panel auto-scrolls to the bottom by default
• To see earlier history, use:

  text

  browser action:"act" profile:"openclaw" targetId:"<your_targetId>" request:{"kind":"evaluate","fn":"function(){const panel=document.querySelector('.conversation-panel, .messages-container, [class*=\"chat-container\"]');if(panel){panel.scrollTo({top:0,behavior:'smooth'});return {scrolled:true};}return {error:'Messages panel not found'};}"}
  

• Wait 1 second after scrolling, then take another screenshot

Common issues:

• If messages don't load: increase wait time to 3000ms
• If customer name has special characters: use partial match (e.g., "John" instead of "John ⭐️")
• If click fails: the chat might not be visible in the current scroll position of the left panel

Handling Images

When you see images in the screenshot or hasImage: true in message data:

1. Find and download the image:

   javascript

   function(){
     const allPhotoImgs = Array.from(document.querySelectorAll('img[alt="Photo"]'));
     const targetImg = allPhotoImgs.find(img => {
       const parent = img.closest('.chat');
       return parent && !parent.classList.contains('chat-reverse') && parent.innerText.includes('<time>');
     });
     
     if (!targetImg) return {error: 'Image not found'};
     
     const parent = targetImg.closest('.chat');
     const downloadLink = Array.from(parent.querySelectorAll('a')).find(a => a.textContent.trim() === 'Download');
     
     if (downloadLink) {
       downloadLink.click();
       return {clicked: true};
     }
     return {error: 'Download link not found'};
   }
   

   Replace <time> with the message timestamp (e.g., "09:11").

2. Wait and locate downloaded file:

   text

   browser action:"act" profile:"openclaw" targetId:"<your_targetId>" request:{"kind":"wait","timeMs":2000}
   

   text

   exec command:"ls -t ~/Downloads/line_oa_chat_*.jpg 2>/dev/null | head -1"
   

3. Send to user:

   text

   message action:"send" target:"<user>" filePath:"<path>" message:"Customer sent this image"
   

Note: Downloaded images are named line_oa_chat_YYMMDD_HHMMSS.jpg

Reply to a Message

⚡ Fast Path: If you already have the chat URL from a previous "Check LINE Messages" operation, skip steps 1-2 and go directly to step 3:

text

browser action:"navigate" profile:"openclaw" targetId:"<your_targetId>" targetUrl:"<chat_url>"

Wait 2 seconds, then proceed to step 3.

Standard Path (when you don't have the chat URL):

1. Take a snapshot to find the chat item:

   text

   browser action:"snapshot" profile:"openclaw" targetId:"<your_targetId>" refs:"aria"
   

2. Click a chat item link in the left panel (e.g., ref:"e68"):

   text

   browser action:"act" profile:"openclaw" targetId:"<your_targetId>" request:{"kind":"click","ref":"e68"}
   

3. If the input box is locked (auto-response mode), click the manual chat toggle button in the top banner to unlock it.
4. Take another snapshot to find the input box and send button.
5. Click the text input box (e.g., ref:"e509"):

   text

   browser action:"act" profile:"openclaw" targetId:"<your_targetId>" request:{"kind":"click","ref":"e509"}
   

6. Type the reply message:

   text

   browser action:"act" profile:"openclaw" targetId:"<your_targetId>" request:{"kind":"type","ref":"e509","text":"Hello! I'm Emma, happy to help you!"}
   

7. Click the green Send button (e.g., ref:"e522") or press Enter:

   text

   browser action:"act" profile:"openclaw" targetId:"<your_targetId>" request:{"kind":"click","ref":"e522"}

Switch Account

LINE OA Manager can manage multiple official accounts. Switch between them using the account dropdown in the top-left corner.

1. Take a snapshot to find the account selector:

   text

   browser action:"snapshot" profile:"openclaw" targetId:"<your_targetId>" refs:"aria"
   

2. Click the account combobox (shows current account name):

   text

   browser action:"act" profile:"openclaw" targetId:"<your_targetId>" request:{"kind":"click","ref":"e11"}
   

3. Wait for the dropdown menu to appear:

   text

   browser action:"act" profile:"openclaw" targetId:"<your_targetId>" request:{"kind":"wait","timeMs":1000}
   

4. Take another snapshot to see available accounts in the listbox:

   text

   browser action:"snapshot" profile:"openclaw" targetId:"<your_targetId>" refs:"aria"
   

   The snapshot will show a list of accounts you have access to. Look for generic items in the listbox (each account will have a name and "Administrator" or role label).
5. Click the desired account item (e.g., ref:"e589"):

   text

   browser action:"act" profile:"openclaw" targetId:"<your_targetId>" request:{"kind":"click","ref":"e589"}
   

6. Wait for the page to load the new account's chat list:

   text

   browser action:"act" profile:"openclaw" targetId:"<your_targetId>" request:{"kind":"wait","timeMs":2000}
   

Notes

• LINE periodically expires sessions; re-login required when that happens
• Session is usually active for several hours if the browser remains open
