A Claude Code skill (and universal SKILL.md) that forces any AI to produce human-sounding text by eliminating statistically detectable AI writing patterns.

Every piece of text the AI produces — tweets, emails, articles, bios, reports, copy and message passes through constraints that eliminate the vocabulary, structure, punctuation, and formatting patterns that readers and detection tools flag as AI-generated.

Based on research from Carnegie Mellon (2025), Wikipedia's Signs of AI Writing page, Buffer's 52M post analysis, and community detection patterns documented across X and Reddit.

• 50+ banned words flagged across multiple AI detection studies (delve, tapestry, landscape, testament, vibrant, pivotal, etc.)
• 35+ banned phrases ("In today's competitive...", "It's worth noting...", "Not just X, but Y", etc.)
• 16 banned sentence openers ("Certainly,", "Moreover,", "Additionally,", etc.)
• 10 structural patterns (rule of three, uniform sentence length, hedging seesaw, corporate pep talk, passive voice, etc.)
• Punctuation tells (em dash overuse, exclamation spam, ellipsis abuse)
• Formatting leaks (markdown in plain text, emoji bullet points, hashtag stacks)
• Accuracy failures (invented statistics, fabricated quotes, fake anecdotes)

/plugin marketplace add jalaalrd/founder-toolkit

Copy the anti-ai-slop-writing folder to ~/.claude/skills/:

cp -r skills/anti-ai-slop-writing ~/.claude/skills/

Copy the SKILL.md file to your tool's skills directory. The SKILL.md format is cross-compatible with 11+ coding agents.

Copy the contents of SKILL.md and paste it at the start of any conversation. It works as a system-level writing constraint.

The skill activates automatically when you ask the AI to write anything. You can also invoke it directly:

/anti-ai-slop-writing

Or just ask: "Write this tweet / email / article and make it sound human."
