How I write a prompt, on a walk
Yesterday, a friend asked how I write a good prompt — and it made me reflect on my process.
I don’t start with one perfect prompt. I start with a conversation.
If I’m thinking about a feature for my pet project, I’ll go for a walk — 1 or 2 miles — talking to ChatGPT about what I want to build, what tech I’m considering, what feels unclear. We go back and forth, more like brainstorming with a friend than writing prompts.
As things get clearer, I ask it to structure everything: generate prompts for design, frontend, implementation — each as its own focused prompt. By the end of the walk, I have a set of actionable prompts ready to go.
Once I’m back at my desk, I implement it (Claude Code), and during review (Codex) I feed the original prompt back in — comparing the outcome to ensure alignment. It’s a continuous flow of turning ideas into action.
Oh, and this exact post? A 15-minute walk with ChatGPT.
