Check instruction applicability

Does the explicit scope of instruction cover task and context?

You need to check whether an instruction applies to the current task and context.

Use instruction-fit in TypeScript

Install with npm install jev-recipes. Requires Node.js 22.9 or newer and ES modules. Set TYPESAFE_API_KEY in your server environment for live calls, which send input to TypeSafe and use API quota. See the installation guide.

import { instructionFit } from 'jev-recipes/instruction-fit';

const result = await instructionFit({
  "instruction": "For customer-facing replies, use plain language.",
  "task": "Write an email explaining a password reset to a customer."
});
console.log(result);
