Multi-Step Prompt Generation Workflow for Product Posters

Enter this instruction and let the AI work through the whole flow step by step — extracting the selling points, settling the style, settling the layout — and finally generate a complete, full-system prompt.

Then hand the AI-generated prompt to the nano banana pro model (it has to be pro). You can first give a few overall-style prompts separately as a global constraint. After that, generating them one at a time or batch-generating with a third-party tool both work.

Machine-translated — the original is what produced this result.
