While the provided schema has a "quantity" field, it doesn't mention the units.

<code>

class Item(BaseModel):

    name: str

    price: float = Field(description="per-unit item price")

    quantity: float = Field(default=1, description="If not specified, assume 1")

class Receipt(BaseModel):

    establishment_name: str

    date: str = Field(description="YYYY-MM-DD")

    total: float = Field(description="The total amount of the receipt")

    currency: str = Field(description="The currency used for everything on the receipt")

    items: list[Item] = Field(description="The items on the receipt")

</code>

There needs to be a better evaluation and a better provided schema that captures the full details of what is expected to be captured.

> What kind of error should it return if there's no total listed on the receipt? Should it even return an error or is it OK for it to return total = null?

Additionally, the schema allows optional fields, so the LLM is free to skip missing fields if they are specified as such.
