Wikipedia editors have spent months cataloguing submissions to figure out what gives away AI-generated text. They compiled a detailed community guide called Signs of AI Writing.
I turned that guide into an open-source self-edit agent skill called Writ:

What it catches: • Stock vocabulary: “delve”, “tapestry”, “testament”, “seamless”, “robust”, “game-changer”
• The “not X, but Y” false-contrast habit: (e.g. “It’s not just a tool, it’s a revolution”)
• Tacked-on significance: (e.g. “…highlighting the shift toward modern efficiency”)
• Em dash overuse & flat sentence rhythm
• Narrow transitions: over-reliance on moreover, furthermore, that said
• Over-formatting: Unnecessary headers, bold text, and bullet points where plain prose reads better
• Leftover assistant voice: (“I hope this helps!”)
How it works:
Instead of rewriting things mechanically or sounding robotic, it runs as a silent self-edit pass right before your agent delivers text. It works with any agent framework that supports loadable skills (Claude Code, Antigravity, Cursor) or can simply be pasted into your system prompt.
