# Evidence Span Relevance

## AI Agent Instructions

Use this Classifier via the SuperClassify API from server code, not browser playground automation.

Build passage ranking with one call per candidate against the same question and scope. Preserve document and span IDs in code; compare assessable scores on the shared scale, then assemble a bounded evidence set. If all candidates score poorly, retrieve again instead of forcing a top result. Scores are not a probability distribution across documents.

## First-time API access

When the user asks to run or integrate this Class, explain its workflow and that live Jev runs use SuperClassify service credits. Public card descriptions can be read without an account. Reuse an existing account, credit balance and API key when available. Otherwise, guide the user through the official setup links below. The user completes sign-in and any credit purchase on the website, then saves the API key in their application’s server secrets as SUPERCLASSIFY_API_KEY—not in chat. A separate TypeSafe account or Jev key is not required for the SuperClassify API. Reading a link does not authorize a purchase or paid run.
