In tidyprompt: Prompt Large Language Models and Enhance Their Functionality

Make LLM answer as a named list

Description

Get a named list from LLM response with optional item instructions and validations.

Usage

answer_as_named_list(
  prompt,
  item_names,
  item_instructions = NULL,
  item_validations = NULL
)

Arguments

prompt	A single string or a tidyprompt() object
item_names	A character vector specifying the expected item names
item_instructions	An optional named list of additional instructions for each item
item_validations	An optional named list of validation functions for each item. Like validation functions for a prompt_wrap(), these functions should return llm_feedback() if the validation fails. If the validation is successful, the function should return TRUE

Value

A tidyprompt() with an added prompt_wrap() that ensures the LLM response is a named list with the specified item names, optional instructions, and validations.
