That code will only trigger if the full sentence is "CLONE!", not if it appears anywhere..
Your description of what you want to do is unclear.

You can use "if ($1 == I'm) to check if the first word is "I'm" (case insensitive, it would also work for I'M or i'M)

but not sure how to specify where the script should find the secondary word(s)
it depends on HOW you want to find that, you need to be more specific
