If you want to be concise, you don't need to say anything is wrong. It is implicit in the correction, where you say how it's wrong. e.g.:
possessives like "rat's" should include an apostrophe
Caution: Contents may have been coded under pressure.

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
