I don't think you can fix the Claude tells without rewriting everything on your own - but I do read/write a lot for work, so I think about voice a lot. Here's a handful of sentences that I feel a human would not have used but which are common Claude constructions:
reply"the alarming ones that are harmless" - We don't put dependent clauses at the end of sentences like this except for unusual emphasis
'quietly' - overused by Claude
the entries here are the moments where the guesswork shows - same as first example
"none of this needs damage or disease" - Also would be written differently as a human. Just try saying some of these things aloud and you'll feel odd
'unknown. nobody has counted it'
