Okay here's one of the outputs:

> Before you start, make sure that your AWS credentials are correct. If they are not, S3 rejects the upload with a permission error.

Wouldn't it be better to write:

Before start, ensure AWS credentials are correct. Otherwise, S3 rejects uploads with permission error.

The example is unambiguous. Your modification is ambiguous at best. <failure to ensure aws credentials are correct> != <aws credentials are incorrect>

Violates rule 4.2: Do not omit words or use contractions to shorten sentences. Keep articles, keep "that".

No, how is that better?

Which one would do better in a college essay? I think the original one, and it has higher word count.

The actual STE standard would score horrendously in a college essay. STE encourages simplification and tons of repetition of words that is discouraged by college professors. It is designed to be clear technical writing for people with a loose grasp of English. College writing encourages complex sentence structure, varied word choice for the same concept and other things that make the writing more interesting at the expense of clarity.
