In addition to calling someone “a smart cookie,” we have several other idioms about being smart – including sharp as a tack and smart as a whip (very intelligent and perceptive), a walking encyclopedia (someone with a LOT of knowledge on many topics), a whiz kid (someone young who is intelligent), a quick study (someone who learns things fast), and street smart (someone who has intelligence in the ways of the world, especially in a city).
One negative idiom with smart is a smart alec or smart aleck – meaning someone who is intelligent, but also arrogant and likes to show off their knowledge in an annoying way. A smart aleck is often clever and sarcastic.
