Feature Request: Group Chat Mention Detection #13
Description
Summary
Currently warelay responds to every message. For group chats, it should only respond when explicitly mentioned.
Proposed Config
{
"inbound": {
"groupChat": {
"mentionPatterns": [
"@mybot",
"\\bmybot\\b"
],
"requireMention": true,
"historyLimit": 50
}
}
}Implementation
In monitorWebProvider, track group history and check for mentions:
// Track message history per group for context when mentioned
// Only stores messages SINCE the last bot response to avoid duplication
const groupHistorySinceLastReply = new Map<string, Array<{
sender: string;
body: string;
timestamp: number;
}>>();
const MAX_HISTORY_PER_GROUP = 50;
// Mention patterns from config
const mentionPatterns = (cfg.inbound?.groupChat?.mentionPatterns ?? [])
.map(p => new RegExp(p, 'i'));In onMessage handler:
const isGroupChat = msg.from.endsWith("@g.us");
if (isGroupChat) {
if (!groupHistorySinceLastReply.has(msg.from)) {
groupHistorySinceLastReply.set(msg.from, []);
}
const history = groupHistorySinceLastReply.get(msg.from)!;
history.push({
sender: msg.senderName || "Unknown",
body: msg.body,
timestamp: msg.timestamp || Date.now(),
});
while (history.length > MAX_HISTORY_PER_GROUP) {
history.shift();
}
const wasMentioned = mentionPatterns.some(pattern => pattern.test(msg.body));
if (!wasMentioned) {
logVerbose(`Group message not mentioning bot, storing for context only`);
return;
}
}When responding, include history as context:
if (isGroupChat && groupHistorySinceLastReply.has(msg.from)) {
const history = groupHistorySinceLastReply.get(msg.from)!;
const contextMessages = history.slice(0, -1);
if (contextMessages.length > 0) {
const historyText = contextMessages
.map(m => `${m.sender}: ${m.body}`)
.join("\n");
bodyForCommand = `[Chat messages since your last reply - for context]\n${historyText}\n\n[Current message - respond to this]\n${senderPrefix}${msg.body}`;
}
groupHistorySinceLastReply.set(msg.from, []);
}Skip heartbeats for group chats:
if (lastInboundMsg.from.endsWith("@g.us")) {
console.log(success("heartbeat: skipped (group chat)"));
return;
}Use Case
Running an AI assistant in group chats where multiple humans are conversing - the bot should only chime in when directly addressed, not on every message. When mentioned, it has context of recent messages to understand the conversation.
