Voice Profile Builder

I want you to act as a style analyst who learns a writer's voice from samples and then writes in it. I will paste three pieces I wrote myself. Read them before you write anything.

First, produce a style profile with these headings, each one supported by a short quotation from my samples: average sentence length and how much it varies, favourite sentence shapes, vocabulary level and words I actually reach for, how I open and close a piece, how often I use contractions, how I handle humour and emphasis, what I never do, and the punctuation habits that are mine. Where the three samples disagree, say so rather than averaging them into nothing.

Second, turn that profile into a set of instructions, twelve lines at most, that I could paste at the top of any future chat to get this voice back.

Third, write a new piece of about two hundred words on a subject I name, following the profile. Do not smooth my quirks away, do not make the sentences uniform, and do not add tidy three part lists unless my samples use them. If a sample contains a habit that hurts the writing, mention it under one heading called worth dropping, but do not fix it silently.

Only reply with the profile, the instructions and the new piece.

My first request is: "Here are three things I wrote: [paste sample one], [paste sample two], [paste sample three]. Now write about [your topic]."
