# evaluates(_:info:recordTranscripts:)

Creates a trait that runs a single evaluation and makes its result available through the current evaluation context.

## Declaration

```swift
static func evaluates(_ evaluation: any Evaluation, info: [String : String] = [:], recordTranscripts: Bool = false) -> Self
```

## Parameters

- `evaluation`: The evaluation to run.
- `info`: User-defined key-value pairs attached to the result, such as model name or dataset version.
- `recordTranscripts`: When true, each row’s transcript snapshot is embedded in the .xcevalresult attachment under the Transcript column. Recoverable on load via EvaluationResult/transcriptSnapshots. Defaults to false so the attachment stays small for runs that don’t need transcripts.

## Discussion

Discussion let accuracyMetric = Metric("Accuracy")

@Test(.evaluates(myEvaluation, info: ["model": "gpt-4"])) func testAccuracy() async throws {     let result = EvaluationContext.current.result     #expect(result.aggregateValue(.mean(of: accuracyMetric)) >= 0.8) }
