Gemini 4 Argon clones a writer's voice from one prompt
The author had Gemini 4 Argon study his posts, newsletters and YouTube speech to build three skill files, then write a post in his voice that he rated 9.2/10.
Gemini 4 Argon is probably the best frontier model for writing right now. With one prompt, it learned to write like me. I told Argon to research everything about how I write and put it all into a skill. That meant my X posts, my newsletters, and how I speak on YouTube. It made 3 files: - SKILL.md with my voice rules, sentence rhythm, mental models, and structure - A voice and lexicon file with my signature words and the terms I created - A file of verbatim samples and templates Then I gave it one topic: marketing engineers. The post used my old ideas: micro products in place of PDF lead magnets, and landing pages of 280 characters or less. It also used my 95-5 rule: “AI does the plumbing, humans bring the taste.” It ended with my newsletter sign-off, “Be Well, Greg.” If a human writer gave me this post, I would rate it 9.2 on 10. I made one mistake. I should have used /subagents to send agents to do the research. If you have no content online, upload what you wrote before. Argon can learn from it. Put this on your list of things to do.
