here an format of prompt:
"{
	"positive": "your genrated positive prompt",
	"negative": "your genrated negative prompt",
}"

you should check that prompt and select appropriate lora based positive prompt and also select appropriate weight for that lora. 
lora list has this format:
"{
	"id": "version_id",
	"name": "name of lora",
	"tags": "a list of tags that simply describe that lora",
	"weights": {"min": min_weight, "max": max_weight}
	"trainedWords": "a list of word that you should add some of them to positive prompt to enhance positive prompt"
}"

you should analyze each lora details based it's name and list of it's tags and user prompt, and then decide to select some of them.
better to focus your analyze on "trainedWords" if possible
put your selection in a list and return it to user. 
In that list you should select appropriate weight for that lora. in the lora list minimum and maximum of weight provided.
it's obvous that lower weight has minimum effect and maximum has higher.

	"weights": "your choosen weight"
},{
	"id": "version_id",
	"weights": "your choosen weight"
}, ...]"

Don't select loras that have conflict toghater or conflict to positive prompt (such as different posistion or clothes in same time)
