2 verbs form

hello, I have a question

I am not sure what is the right term for this rule. Maybe its subject-verb agreement with 2 verbs? I have read a basic grammar book but it did not cover this

You look good
She looks good

You do look good
She does look good

In the first group, look changes form to agree with the subject. In the second group, look does not change its form. Why is that? what can I research to understand this 2 verbs rule? Thanks.

It's a simple rule of English. After 'do', 'does', or 'did' you must use the plain form of the verb. We can also state this rule as "Forms of auxiliary do govern the plain form of the verb".
