humanize-writing

A Claude Code skill that rewrites AI-generated content to sound like a human wrote it.

What it does

Detects and fixes common AI writing patterns through an 8-pass editing process:

1. Structure tells – formulaic sections, identical list lengths, tidy takeaways
2. Significance inflation / promotional language – “pivotal moment,” “nestled,” “vibrant”
3. AI vocabulary – “delve,” “landscape,” “leverage,” “tapestry,” and dozens more
4. Grammar-level patterns – copula avoidance, -ing phrases, synonym cycling, false ranges
5. Rhythm and style – metronomic cadence, em dash overuse, boldface, emoji, curly quotes
6. Hedging, filler, and vague attributions – “It’s worth noting,” chatbot artifacts, sycophancy
7. Connective tissue – “Moreover,” “Furthermore,” “Additionally” on repeat
8. Human texture and soul – adding opinions, lived experience, personality

See SKILL.md for the full editing process and references/ai-tells.md for the complete detection checklist.

Install

Via skills.sh (GitHub-based)

npx skills add jpeggdev/humanize-writing

Via npm

npm install -g @jpeggdev/humanize-writing

The postinstall script copies the skill files to ~/.claude/skills/humanize-writing/ (and equivalent directories for Cursor and Windsurf).

Usage

Once installed, the skill activates automatically in Claude Code when you say things like:

• “humanize this”
• “sounds like AI”
• “make it sound human”
• “too robotic”
• “de-AI this”

Credits

This skill combines two approaches:

• The pass-based editing workflow and ai-tells reference from humanize-writing
• The 24 Wikipedia-sourced patterns and “soul” philosophy from humanizer by blader

Primary reference: Wikipedia: Signs of AI writing, maintained by WikiProject AI Cleanup.
