Multi-turn user requests:
user: What's the name of the python file my current directory? There should be only one and. Do not list hidden files. 
user: Use grep to find out the name of the function of the script.
user: And while we're diving into the deployments, let's pinpoint every mention of 'update' in this script and jot those lines down for scrutiny.
user: Once that's sewn up, it'd be helpful to buzz Catherine with the first update you have found, with message 'update the system'. If you need, my user_id is 'USR002'
user: Could you double check if the message is sent?
