containsAny
Checks whether at least one accepted phrase or pattern appears in the answer.
When to use
Several wordings or phrases are acceptable.
Why use it
It avoids rejecting valid alternatives.
Example
This example evaluates a fixed output so you can see what the metric checks. Replace target with your agent or function when building your own suite.
import { containsAny, runEvalSuite } from '@anvia/core/evals'
const result = await runEvalSuite({
name: 'contains-any-example',
cases: [
{
id: 'billing-role',
input: 'Who can change billing settings?',
},
],
target: async () => 'Workspace owners can change billing settings.',
metrics: [
containsAny({ expected: ['Workspace owners', 'Account administrators'] }),
],
})
console.log(result.results[0]?.scores)Read the result
This example passes with score true because one accepted phrase is present. An answer that matches none of the options fails.
What it needs
Output text and a nonempty array of strings or regular expressions; passes when at least one item is found.
Keep in mind
Use a nonempty array of accepted alternatives. This metric requires only one match. Choose containsAll when every item must appear.
For an object returned by your target, use actual to select the value to check, such as actual: ({ output }) => output.answer. Anvia automatically reads the output field of an agent response.
An invalid result means the metric could not make a valid judgment, for example because required input was missing or a model call failed. Inspect it separately from a failed check.
