How can i manually trigger again agent to answer the question while tool transfer?
t
Thanks for reaching out, Akshay. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.
Could you clarify what you mean by "manually trigger again agent to answer the question while tool transfer"? Are you referring to a specific feature or scenario in LiveKit, such as reactivating an agent during a handoff or tool execution?
c
LIke i have got query in tool but i ran some task and i dont think it should be answer by current tool instead go to other agent. It can answer immediately dont wait to user ask again.
t
If you want to redirect a query to another agent in LiveKit right away, without waiting for the user to say anything, here are a couple of easy ways to do it: 1. Using the 
update_agent()
Method: You can simply call the 
update_agent()
method on the session to switch to a different agent immediately. Here’s a quick example:
Copy code
from livekit.agents import Agent

# Let’s say you have a CustomerServiceAgent class defined
session.update_agent(CustomerServiceAgent())
2. Returning a Different Agent from a Tool Call: Another way is to return a new agent instance right from a tool call, which hands off control automatically. Like this:
Copy code
from livekit.agents import Agent, function_tool

class ConsentCollector(Agent):
    @function_tool()
    async def on_consent_given(self):
        # Hand off by returning the new agent
        return HelpfulAssistant()
Just make sure the new agent is set up properly and has everything it needs to keep the conversation flowing smoothly. If you want, I’m here to help you with the implementation—just let me know! Sources: Workflows | LiveKit Docs | Workflows | LiveKit Docs

It will auto answer current query?
t
Hey there! Just so you know, LiveKit doesn’t automatically respond to the query when it redirects you to another agent. The new agent who picks up the conversation will take care of answering your question. You can use things like 
session.update_agent()
to hand things over, but the reply needs to come from the agent on the other end. Hope that clears things up! Sources: Workflows | LiveKit Docs | Dispatching agents | LiveKit Docs

Example
t
Here’s a simple example of how you can redirect a query to another agent and make sure the new agent takes care of the response:
Copy code
from livekit.agents import Agent

class InitialAgent(Agent):
    async def on_user_turn_completed(self, turn_ctx, new_message):
        if "transfer" in new_message.text_content.lower():
            # Transfer to another agent
            session.update_agent(SecondAgent())

class SecondAgent(Agent):
    async def on_enter(self):
        # Automatically respond to the user upon taking over
        await self.session.generate_reply("I am the new agent handling your query.")
Here’s what’s happening: • The 
InitialAgent
looks out for a trigger word like "transfer" in the message and then switches control over to 
SecondAgent
. • Once 
SecondAgent
takes over, it immediately replies to the user using 
generate_reply()
. If you want me to walk you through this more or need other examples, just let me know—I’m here to help!

So inbetween transfer can i manully run llm to answer so no gap....
t
Absolutely, you can manually trigger the LLM to jump in and answer during an agent transfer to keep things smooth and avoid any awkward pauses. Here are a few ways to do that: 1. Preemptive Generation: Turn on preemptive response generation so the LLM starts crafting its reply before the transfer finishes, which helps cut down any wait time. 2. Manual Turn Control: Use handy methods like 
commit_user_turn
or 
clear_user_turn
to take charge of when the LLM responds during the transfer. 3. Interrupt Handling: The 
interrupt
method is great for stopping any ongoing speech and quickly prompting the LLM to reply right away. 4. Event-Driven Triggers: Keep an ear out for state changes (like when an agent session starts or ends) to nudge the LLM to respond exactly when it’s needed during the handoff. For instance, you might have the LLM say something like "Now transferring you to another agent" while the handoff is happening. If you'd like, I’d be happy to walk you through a detailed example on how to set this up! Sources: Tool definition and use | LiveKit Docs

After handoff re-generate response of latest user query
