humanizer Codifies 33 Specific AI-Writing Tells Into an Agent Skill — Em-Dash Overuse, Copula Avoidance and Synonym Cycling Among Them

GitHub·medium signal

At 31,581 stars and +1,504 this week, humanizer enumerates 33 machine-writing patterns across four categories: content (significance inflation, vague attributions, promotional language), language (AI vocabulary like "testament", copula avoidance like "serves as", excessive hedging), style (em-dash overuse, title case headings, emojis, curly quotes) and communication (chatbot artifacts, sycophantic tone, filler). It adds voice calibration to match personal writing style and enforces a no-fabrication rule so rewrites never introduce facts or citations absent from the source. Because the runtime is plain Markdown it works across Claude Code, Cursor and Codex.
