Adjectives describe a noun which is marked by が.

> 僕は料理が得意。

Could it be rewritten as

> 僕には料理が得意。

Or is it wrong?

Regarding adjectives, a sentence like this would be correct:

> 僕にはペンが必要です。

Would a sentence like the following one be correct?

> 僕がペンを必要する。

(I think I should say 必要にする, but I am not sure.)

Adjectives and particles が に
> 僕には料理が得意

when you say like this, it will give the impression that someone else you are
going to talk about is not good at cook.

It's same like this,

> 僕 **には** できません I can't do it (but someone can do it)

僕がペンを大切にする can be translated as I care about the pen.

answer
> 僕には料理が得意。

is simply ungrammatical.

> 僕にはペンが必要です。

is grammatical only because 必要だ can take two arguments (AがBに) as **word-
specific** feature, not that it's a universal grammar for adjectives. It's
like the English word [_worth_ can have an object but most other adjectives
can't](https://english.stackexchange.com/questions/447990/similar-adjectives-
to-worth).

Other adjectives that take に include ふさわしい (あなたが隊長にふさわしい) and 夢中だ (僕は君に夢中だ)
etc., but basically you have to learn one by one.

And as already pointed out in comments above:

> × 僕がペンを必要する。  
>  僕がペンを必要にする。 → _I make the pens necessary._  
>  僕がペンを必要とする。 → _I necessitate a pen._

na-adjective + `にする` results in a verb "make ... _adjective_ " and `とする`
"regard ... _adjective_ ".
