Caura Rail for TypeScript and JavaScript

Memory operations around agent turns: fetch governance rules and relevant facts from Caura before your agent runs, then extract and store facts from the completed turn. ES modules for Node.js 22+, no runtime dependencies, type declarations included.

npm install @caura/rail

import { MemoryScope, Rail, RestMemoryStore } from "@caura/rail";

const rail = new Rail({
  store: RestMemoryStore.fromEnv(process.env), // CAURA_URL, CAURA_API_KEY
  scope: new MemoryScope({ agentId: "support-1" }),
});
const turn = await rail.turn("Remember: We deploy in eu-west-1.", async (message, context) => {
  return "Noted. " + context.text; // pass context to your model
});
console.log(turn.reply, turn.writes.map(w => w.status));

Full documentation, including the guide, API reference, and reliability semantics, lives in the repository. A Python package with the same semantics is published as caura-rail.
