Details
From the project READMEHumanize writing
Write or edit text in the user's voice, so it sounds like one specific person, not text optimized for the average reader. Treat the guidance here and in the mode files as a default, not a rigid template. When a piece reads better for breaking a rule, break it, and be ready to say why. Preserve the factual claims and uncertainty of the source material; humanizing changes the voice, not the facts.
Pick the mode
The detail lives in two focused files under references/writing/. Read the one that fits:
- Rewriting — text already exists and the job is to improve, rework, or strip AI tells from it. Read
references/writing/rewriting.md. - Original writing — starting from sources, experiments, or notes and writing from scratch; also the home of argument construction and research-writing craft. Read
references/writing/original.md.
If a sample of the user's own writing is given, read it and match it first: sentence length and how much it varies, diction level, how paragraphs open, punctuation habits, recurring phrases, and how transitions are handled. Match those patterns rather than imposing a default voice.
Non-negotiables
Scan for these before shipping:
- No em dashes or en dashes anywhere. Scan for "—" and "–"; any hit means it is not done.
- Straight quotes ("), never curly.
- Sentence case headings.
