⚠️ 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 refs:"aria" compact:true to find element refs, then act + click/type with ref.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)Before first use, check if config.json exists:
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:
bashcd skills/line-oa node scripts/setup.js
This is the first step for all operations below.
browser action:"status" If "running": false, start the browser service: browser action:"start" profile:"openclaw" Wait 2-3 seconds for the service to initialize.
read file_path:"skills/line-oa/config.json" Extract chatUrl from the JSON (e.g., https://chat.line.biz/U1234567890abcdef1234567890abcdef/).
browser action:"open" profile:"openclaw" targetUrl:"<chatUrl>" Capture targetId and url from response.
browser action:"act" profile:"openclaw" targetId:"<targetId>" request:{"kind":"wait","timeMs":2000}
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: read file_path:"skills/line-oa/scripts/click-line-account.js" Execute the script directly: browser action:"act" profile:"openclaw" targetId:"<targetId>" request:{"kind":"evaluate","fn":"<script_content>"} Wait 2 seconds.
b. Click Login button: read file_path:"skills/line-oa/scripts/click-login.js" Execute the script directly: browser action:"act" profile:"openclaw" targetId:"<targetId>" request:{"kind":"evaluate","fn":"<script_content>"} Wait 3 seconds.
c. Reload chatUrl: 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
a. Open a blank tab: browser action:"open" profile:"openclaw" targetUrl:"about:blank"
b. Get all tabs: browser action:"tabs" profile:"openclaw"
c. Close all tabs except the newest one (about:blank): 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.
Complete flow: login → list chats → report. Follow these steps exactly.

If you only thought about it but didn't call it, STOP and call it NOW. You MUST see a tool result before continuing.
<name> (<time>) <lastMsg> [未讀] or [已讀] based on unread field. If empty array, say "目前沒有聊天記錄".about:blank, list all tabs, close everything except about:blank.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).
read file_path:"skills/line-oa/scripts/list-chats.js"
Pass the script content directly as the fn parameter: browser action:"act" profile:"openclaw" targetId:"<your_targetId>" request:{"kind":"evaluate","fn":"<script_content>"}
[{ name: string, time: string, lastMsg: string, unread: boolean }]
name: customer display nametime: timestamp (e.g., "21:32", "Yesterday", "Friday")lastMsg: last message preview (~100 chars)unread: true if green dot present, false otherwiseFor each unread chat, click into it to get the direct URL, then return to list: 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: browser action:"act" profile:"openclaw" targetId:"<your_targetId>" request:{"kind":"evaluate","fn":"function(){return window.location.href;}"}
Navigate back to list: 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.
unread: true exists: List each unread chat with name, time, preview, and URL (if obtained)span.badge.badge-pin inside each chat list item (green dot)lastMsg shows the last message in the thread, which may be an auto-response rather than the customer's original messageOpens 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).
Use evaluate to find the chat item by name (more reliable than snapshot for dynamic chat list): 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.
browser action:"act" profile:"openclaw" targetId:"<your_targetId>" request:{"kind":"wait","timeMs":2000}
browser action:"screenshot" profile:"openclaw" targetId:"<your_targetId>"
The screenshot will show:
If you need structured message data instead of a screenshot, read and run this script: read file_path:"skills/line-oa/scripts/read-messages.js" Execute: browser action:"act" profile:"openclaw" targetId:"<your_targetId>" request:{"kind":"evaluate","fn":"<script_content>"}
Returns an array of recent messages with:
time: timestamptext: message contentisCustomer: true if from customer, false if from youhasImage: true if message contains an imageTo scroll to earlier messages:
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'};}"}
Common issues:
When you see images in the screenshot or hasImage: true in message data:
javascript function(){ const allPhotoImgs = Array.from(document.querySelectorAll('imgalt="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").
browser action:"act" profile:"openclaw" targetId:"<your_targetId>" request:{"kind":"wait","timeMs":2000} exec command:"ls -t ~/Downloads/line_oa_chat_*.jpg 2>/dev/null | head -1"
message action:"send" target:"<user>" filePath:"<path>" message:"Customer sent this image"
Note: Downloaded images are named line_oa_chat_YYMMDD_HHMMSS.jpg
⚡ 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:
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):
browser action:"snapshot" profile:"openclaw" targetId:"<your_targetId>" refs:"aria"
ref:"e68"): browser action:"act" profile:"openclaw" targetId:"<your_targetId>" request:{"kind":"click","ref":"e68"}
ref:"e509"): browser action:"act" profile:"openclaw" targetId:"<your_targetId>" request:{"kind":"click","ref":"e509"}
browser action:"act" profile:"openclaw" targetId:"<your_targetId>" request:{"kind":"type","ref":"e509","text":"Hello! I'm Emma, happy to help you!"}
ref:"e522") or press Enter: browser action:"act" profile:"openclaw" targetId:"<your_targetId>" request:{"kind":"click","ref":"e522"}
Each chat has a Notes panel on the right side. Notes are internal-only (not visible to customers). Max 300 characters per note.
Tags are shown in the right panel below the user's name. They are predefined labels for categorizing chats.
LINE OA Manager can manage multiple official accounts. Switch between them using the account dropdown in the top-left corner.
browser action:"snapshot" profile:"openclaw" targetId:"<your_targetId>" refs:"aria"
browser action:"act" profile:"openclaw" targetId:"<your_targetId>" request:{"kind":"click","ref":"e11"}
browser action:"act" profile:"openclaw" targetId:"<your_targetId>" request:{"kind":"wait","timeMs":1000}
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).
ref:"e589"): browser action:"act" profile:"openclaw" targetId:"<your_targetId>" request:{"kind":"click","ref":"e589"}
browser action:"act" profile:"openclaw" targetId:"<your_targetId>" request:{"kind":"wait","timeMs":2000}
