Thanks — I’m responding about how to make an agent call a tool from

generate_reply()

for your two cases. • Case 1 — Agent already has the tool: ◦ You don’t need to pass the tool to

generate_reply()

. If the tool is in the agent’s tool list, the LLM can call it automatically during the ReAct reasoning loop when appropriate. Just call

generate_reply()

(or

generateReply

) with your instructions/user input and the agent will invoke any available tool it decides to use. • Case 2 — Agent does not have the tool: ◦ You cannot pass a one-off tool into

generate_reply()

. First add the tool to the agent’s tool list (for example, with

agent.update_tools(...)

or

agent.updateTools(...)

). After the tool is added, subsequent

generate_reply()

calls can use that tool. There is no built-in way to temporarily provide a tool for a single

generate_reply()

call. If you want, tell me which SDK (Python or TypeScript) you’re using and the tool definition you have, and I’ll give the exact code snippet to add the tool and call

generate_reply()

. Sources: https://docs.livekit.io/agents/logic/tools/definition.md|, with interactive elements
