Choose whether an event observes or acts

You choose an explicit action for every route: observe, invalidate, wake, or resume. Only wake and resume may invoke a model.

route('resource-updated').source('mcp.resource').identity(requireAccount).wake(target)
Run itIn your own project
npm install @ax-llm/ax

import { ai, ax } from '@ax-llm/ax';

const llm = ai({ name: 'openai', apiKey: process.env.OPENAI_APIKEY! });
const classify = ax('review:string -> sentiment:class "positive, negative, neutral"');

const result = await classify.forward(llm, {
  review: 'Useful and boring in the best way.',
});

Set OPENAI_APIKEY in your environment before running provider-backed code.
