CacheContext

CORE · interface · 类型合同

Cache access shared by workflow visits and the low-level $step loop.

导入

TypeScript

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

JavaScript

/** @typedef {import('@jangts/agent-core/engine').CacheContext} CacheContext */

其他公开入口：@jangts/agent-core、@jangts/agent-core/engine、@jangts/agent-core/types、@jangts/agent-core/structs。

定义

interface CacheContext

字段结构

字段	类型	必需	说明
cache	NodeCache	必需	只读。见类型定义及调用场景。
agentCache	NodeAgentCache | undefined	可省略	只读。见类型定义及调用场景。

使用示例

• Agent：先运行，再逐步绑定 Tool 与依赖：Engine 执行有界循环；绑定 Workflow 后，每次只传状态中变化的数据。
• Workflow：节点、路由与局部状态更新：用一份真实参与运行的节点定义，集中展示执行顺序、分支、错误去向和结束条件。

一个普通步骤即可运行

入门 · 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);

增加显式 Workflow，仍然调用 run

配置 · 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' }));
