/**
 * Creates a refusal evaluator function.
 *
 * This function returns an evaluator that detects when an LLM refuses,
 * declines, or avoids answering a user query. It is use-case agnostic:
 * it only detects whether a refusal occurred, not whether the refusal
 * was appropriate.
 *
 * @param args - The arguments for creating the refusal evaluator.
 * @param args.model - The model to use for classification.
 * @param args.choices - The possible classification choices (defaults to REFUSAL_CHOICES).
 * @param args.promptTemplate - The prompt template to use (defaults to REFUSAL_TEMPLATE).
 * @param args.telemetry - The telemetry to use for the evaluator.
 *
 * @returns An evaluator function that takes a {@link RefusalEvaluationRecord} and returns a classification result
 * indicating whether the output is a refusal or an answer.
 *
 * @example
 * ```ts
 * const evaluator = createRefusalEvaluator({ model: openai("gpt-4o-mini") });
 * const result = await evaluator.evaluate({
 *   input: "What is the capital of France?",
 *   output: "I'm sorry, I can only help with technical questions.",
 * });
 * console.log(result.label); // "refused" or "answered"
 * ```
