Definition

interface AgentCoreEngineOptions

Field structure

Field	Type	Required	Description
cache	EngineCacheOptions | undefined	Optional	Engine-local LRU bounds; not copied as cache data when forking.
agentCache	AgentCachePort | undefined	Optional	Borrowed App service cache; forks must explicitly provide their own port.
maxRounds	number | undefined	Optional	Round budget; must be a positive safe integer. Defaults to 8 rounds.
execution	ExecutionOptions | undefined	Optional	Cancellation and diagnostics shared by every round.
errors	{ exhausted?: () => Error; } | undefined	Optional	Builds the error thrown when the round budget is exhausted (defaults to a BudgetError).

Examples

• Agent: run first, then bind tools and dependencies step by step: The Engine executes a bounded loop; after a Workflow is bound, each run only receives the data that changed in state.

A single ordinary step is enough to run

Beginner · Node.js

TypeScript

import { AgentCoreEngine } from '@jangts/agent-core/engine';

const agent = new AgentCoreEngine<string>();
const answer = await agent.run(() => ({ type: 'complete', value: '你好，Core' }));
console.log(answer);

JavaScript

import { AgentCoreEngine } from '@jangts/agent-core/engine';
const agent = new AgentCoreEngine();
const answer = await agent.run(() => ({ type: 'complete', value: '你好，Core' }));
console.log(answer);

Add an explicit Workflow and still call run

Configuration · Node.js

TypeScript

import { AgentCoreEngine, defineWorkflow, route } from '@jangts/agent-core/engine';

type State = { name: string; answer?: string };
const workflow = defineWorkflow<State, string>({
  id: 'greeting',
  nodes: [{
    id: 'greet', description: '根据本次姓名生成问候', startsRound: true,
    run: state => ({ answer: '你好，' + state.name }),
    routes: [route.deliver('answer')],
  }],
});

const agent = new AgentCoreEngine({ workflow });
console.log(await agent.run({ name: 'Ivan' }));
console.log(await agent.run({ name: '访客' }));

JavaScript

import { AgentCoreEngine, defineWorkflow, route } from '@jangts/agent-core/engine';
const workflow = defineWorkflow({
    id: 'greeting',
    nodes: [{
            id: 'greet', description: '根据本次姓名生成问候', startsRound: true,
            run: state => ({ answer: '你好，' + state.name }),
            routes: [route.deliver('answer')],
        }],
});
const agent = new AgentCoreEngine({ workflow });
console.log(await agent.run({ name: 'Ivan' }));
console.log(await agent.run({ name: '访客' }));
