I believe the answer is:

pager

I'm a little stuck... Click here to teach me more about this clue!

'alert' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'pompeo and rudy for starters time to get involved' is the wordplay.
'pompeo' becomes 'p' (this could be a standard abbreviation of which I'm unaware).
'and' says to put letters next to each other.
'for starters' suggests taking the first letters.
'time' becomes 'age' (age is a kind of time).
'to get involved' indicates putting letters inside.
The first letter of 'rudy' is 'r'.
'p'+'r'='pr'
'pr' placed around 'age' is 'PAGER'.

Can you help me to learn more?
