I've noticed that some nouns can be described with すべき, as in

> 彼女{かのじょ}はもっと注意{ちゅうい}すべきだった。 (She _should_ have been more careful.)

I understand it as

> 彼女{かのじょ}はもっと注意{ちゅうい}するだった。 (She has been more careful.)

being a complete sentence on its own, and the "shouldness" acting as a
modifier.

However, if I wanted to say "Her explanation should be precise", modified
from,

> 彼女の説明は具体的。("Her explanation is precise")

I'm not too certain how to insert the する into the sentence, so that すべき can
act as a modifier in this particular case.

question
grammar
Describing an adjective with "should"
注意するだった is ungrammatical.

I think you could think of it this way:

> 注意する -- is careful / pay attention  
>  注意した -- was careful / paid attention  
>  注意す(る)べきだ -- should be careful / should pay attention  
>  注意す(る)べきだった -- should have been careful / should have paid attention

* * *

The _full_ sentence would be:

> 彼女の説明は具体的 **だ** 。

To say "Her explanation _should be_ concrete":

> 彼女の説明は具体的 **であるべきだ** 。

べき follows a verb (eg 食べるべき, 言うべき, やるべき, す(る)べき) and can't directly follow だ.  
To use it with an i-adjective 美しい, you say 美し **くあるべき** ; with a na-adjective
きれいだ, きれい **であるべき**.

* * *

To rewrite your example using **す** べき without changing the meaning, I'd
say...

> 「彼女は具体的に説明す(る)べきだ。」← using the する-verb 「説明する」"explain"  
>  _lit._ "She should explain concretely."  
>  (or maaybe 「彼女の説明を具体的にす(る)べきだ。」← 「～を…にする」= "make ~ …"  
>  "(She/Someone/You?) should make her explanation concrete.")
