Yes, I'd agree with Jmat. The word good is describing a noun, not a verb.
In the following dialogue for example:
Do you like my new hairstyle?
Yes, it looks good.
The word 'good' refers to the hairstyle.
Or in Altini's dialogue above, the comment 'Sounds good' or 'It sounds good' is your opinion of the suggestion. Good describes the idea (it) not the word verb 'sounds'.
You could say both of the following to a friend, but they would have different meanings:
You look good : You look nice, smart, pretty, attractive
You look well: You look healthy, relaxed, stress-free
