Single Context Agent

import { createDreams, context, input, output } from "@daydreamsai/core";
import { cliExtension } from "@daydreamsai/cli";
import { openai } from "@ai-sdk/openai";
import * as z from "zod";

// 1. Define the main context for our agent
const echoContext = context({
  type: "echo",
  // No specific arguments needed for this simple context
  schema: z.object({}),
  // Instructions that guide the LLM's behavior
  instructions:
    "You are a simple echo bot. Repeat the user's message back to them.",
});

// 2. Create the agent instance
const agent = createDreams({
  // Configure the LLM model to use
  model: openai("gpt-4o-mini"),
  // Include the CLI extension for input/output handling
  extensions: [cliExtension],
  // Register our custom context
  contexts: [echoContext],
});

// 3. Start the agent and run the context
async function main() {
  // Initialize the agent (sets up services like readline)
  await agent.start();

  console.log("Echo agent started. Type 'exit' to quit.");

  // Run our echo context
  // The cliExtension automatically handles console input/output
  await agent.run({
    context: echoContext,
    args: {}, // Empty object since our schema requires no arguments
  });

  // Agent stops when the input loop breaks (e.g., user types "exit")
  console.log("Agent stopped.");
}

// Start the application
main();
