Why I Started Treating GPT Like A Junior Ghostwriter

I write a lot, but I do not always feel like typing a lot.

So I started using GPT as a sort of junior ghostwriter for my blog on richardlemon.com. Not to "create content". To keep my publishing cadence up while I am busy shipping weird web experiments and coaching baseball.

The problem: every unconfigured model sounds the same. Smooth. Bland. Corporate. Like it just finished a LinkedIn course on "thought leadership".

So for three months I iterated on a single system prompt. Same idea. Lots of small edits. My goal was simple. Posts that still sound like me after the AI takes a pass at the keyboard.

This post is the current state of that system prompt. The exact text. The banned phrases. The structure rules. Plus what actually moved the needle.
