Build a concrete LLM prompt from a template — build

This function takes a prompt template (typically from set_prompt_template), a trait name and description, and two writing samples, and fills in the required placeholders.

Usage

build_prompt(template, trait_name, trait_desc, text1, text2)

Arguments

template: Character string containing the prompt template.
trait_name: Character scalar giving a short label for the trait (e.g., "Overall Quality").
trait_desc: Character scalar giving the full definition of the trait.
text1: Character scalar containing the text for SAMPLE_1.
text2: Character scalar containing the text for SAMPLE_2.

Value

A single character string containing the completed prompt.

Details

The template must contain the placeholders: {TRAIT_NAME}, {TRAIT_DESCRIPTION}, {SAMPLE_1}, and {SAMPLE_2}.

Examples

tmpl <- set_prompt_template()
td <- trait_description("overall_quality")
prompt <- build_prompt(
  template   = tmpl,
  trait_name = td$name,
  trait_desc = td$description,
  text1      = "This is sample 1.",
  text2      = "This is sample 2."
)
cat(substr(prompt, 1, 200), "...\n")
