The summary describes the store. The custom prompt tells the model what to emphasize. They are separate fields.
Use the summary for the opening quote. Use the prompt for instructions such as leading with shipping or keeping each note short.
Which field to use
- Summary: what the store is
- Prompt: what this file should emphasize
- Neither field can add a URL the app did not load
- You can fill one and leave the other empty
If you only have one sentence, put it in the summary. Add a prompt when you want a particular page or policy mentioned first.
