07/30/2025, 1:58 AMHow do I access and iterate through existing messages in a LiveKit ChatContext object?
I need to modify assistant messages to add a "name" field, but chat_ctx.messages gives me an AttributeError. What's the correct attribute or method
to access the list of existing ChatMessage objects in a ChatContext?

07/30/2025, 1:59 AMThe correct way to access and iterate through existing messages in a LiveKit
ChatContextitemsChatMessageFunctionCallChatMessage Copy code
# Access all items
all_items = chat_context.items
# Filter for ChatMessage objects only
chat_messages = [item for item in chat_context.items if item.type == "message"]
# Iterate through all items
for item in chat_context.items:
if isinstance(item, ChatMessage):
print(item.role, item.text_content)messages Copy code
// Access messages array
const chatMessages = chatContext.messages;
// Iterate through messages
for (const message of chatContext.messages) {
console.log(message.role, message.content);
}
// Or using array methods
chatContext.messages.forEach(message => {
// Process each ChatMessage
});messagesc

07/30/2025, 2:04 AMHow do I add a "name" field to an existing ChatMessage object in LiveKit Python SDK?
I'm trying to set message.name = "AgentName" on ChatMessage objects from chat_ctx.items, but I get the error: "ChatMessage" object has no field
"name".
What's the correct way to:
1. Add a name field to an existing ChatMessage?
2. Or create a new ChatMessage with a name field to replace an existing one?
3. Or modify the ChatContext to include agent names in assistant messages?
I need to add agent attribution to assistant messages for proper tracking across agent handoffs.
