SubFlowValue
CORE · type · Type contract
JSON-like value accepted in reported payloads; depth and size are bounded by the recorder.

Examples
- Process observation and node reports: The App subscribes to Core execution facts; nodes report their own usedModel and use an instance sub-logger to record intent first and then results, while the Loop owns identity and logging.
Observe the nodes and model events a task passes through
Beginner · Node.js
ts
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, execution: {
observe: { event(event) { console.log(event.type, event.eventId); } },
} });
console.log(await agent.run({ name: 'Ivan' }));js
import { AgentCoreEngine, defineWorkflow, route } from '@jangts/agent-core/engine';
const workflow = defineWorkflow({
id: 'greeting',
nodes: [{

Configuration · Node.js
The node only reports facts it knows; Core owns node identity and execution association.
ts
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: '生成问候', startsRound: true,
run(state, context) {
context.report({ payload: { phase: 'formatting' } });
return { answer: '你好，' + state.name };
}, routes: [route.deliver('answer')],
}] });
const agent = new AgentCoreEngine({ workflow, execution: {
observe: { event(event) { console.log(event.type); } },
} });
console.log(await agent.run({ name: 'Ivan' }));js
import { AgentCoreEngine, defineWorkflow, route } from '@jangts/agent-core/engine';
const workflow = defineWorkflow({ id: 'greeting', nodes: [{
id: 'greet', description: '生成问候', startsRound: true,
run(state, context) {
context.report({ payload: { phase: 'formatting' } });
return { answer: '你好，' + state.name };
}, routes: [route.deliver('answer')],
}] });
const agent = new AgentCoreEngine({ workflow, execution: {
