How you could try it
Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into Claude or any similar agent and adjust the details to your situation.
Creative task: generate parametric CAD models from a prompt. Outline first, then draft. Preserve my voice; ask before posting publicly.
The prompt breaks down into 3 steps you can check as the agent works:
- Creative task: generate parametric CAD models from a prompt.
- Outline first, then draft.
- Preserve my voice; ask before posting publicly.
Tip: Start small: run it once on a low-stakes example, read what the agent did, and only then let it run on real work.
