# Make agent hold and respond nothing

Sometimes you might want the agent to hold and not respond to the user, like when user says "hold on" or "give me a minute".

We hard-coded a stop sequence in the LLM: `NO_RESPONSE_NEEDED`. Whenever this sequence is met, the response generation stops.
You can then prompt the LLM to output nothing by writing something like:

```
- if user says "hold on", reply exactly the following: "NO_RESPONSE_NEEDED".
```
