OptionalagentA list of tools available to the agent, for TrajectoryEvalChain.
OptionalchainOptionalcriteria?: undefined | (CriteriaLike & (Record<string, string> | Criteria))The criteria to use for the evaluator.
OptionaldistanceThe distance metric to use for comparing the embeddings.
Optionalembedding?: anyThe embedding objects to vectorize the outputs.
Optionalllm?: anyThe criteria to use for the evaluator.
The language model to use for the evaluator.
The configuration for the evaluator.
const evalConfig = {
  evaluators: [LabeledCriteria("correctness")],
};
@example
```ts
const evalConfig = {
  evaluators: [
    LabeledCriteria({
      "mentionsAllFacts": "Does the include all facts provided in the reference?"
    })
  ],
const evalConfig = {
  evaluators: [{
    evaluatorType: "labeled_criteria",
    criteria: "correctness",
    formatEvaluatorInputs: ...
  }],
};
const evalConfig = {
  evaluators: [{
    evaluatorType: "labeled_criteria",
    criteria: { "mentionsAllFacts": "Does the include all facts provided in the reference?" },
    formatEvaluatorInputs: ...
  }],
Configuration to load a "LabeledCriteriaEvalChain" evaluator, which prompts an LLM to determine whether the model's prediction complies with the provided criteria and also provides a "ground truth" label for the evaluator to incorporate in its evaluation.
