RecordedSubStep

CORE · interface · 类型合同

A step already accepted by a logger, carrying recorder-assigned bookkeeping fields.

导入

定义

interface RecordedSubStep

继承或实现： ReportedStep。

字段结构

字段	类型	必需	说明
origin	"reported"	必需	只读。Historical marker: only self-reported steps are recorded.
operation	"write" | "fix" | undefined	可省略	只读。Append-only logging operation, separate from the App-owned business type.
targetStepId	string | undefined	可省略	只读。Original write record revised by this fix; fixes have their own stepId.
sequence	number	必需	只读。One-based append order within the node visit, including every fix.
createdAtMs	number | undefined	可省略	只读。Optional only for historical records produced before the logger contract.
revision	number | undefined	可省略	只读。Revision number, incremented by each accepted fix.
payload	Readonly<Record<string, SubFlowValue>> | undefined	可省略	只读。Reported payload; the recorder snapshots it and bounds the total size.
type	string | undefined	可省略	只读。App-defined business log type; never a write/fix operation enum.
subnodeId	string | undefined	可省略	只读。Logical subnode grouping within this node visit; independent of individual log ids.
stepId	string	必需	只读。Log record identity, unique within one node visit; not a subnode id.
parentStepId	string | undefined	可省略	只读。Reported parent step, forming a tree; absent for a top-level step.
relatedDefinitionId	string | undefined	可省略	只读。Self-reported reference only; never a workflow dispatch identity.
relatedInvocationId	string | undefined	可省略	只读。Real model/tool invocation identity, kept separate from the node-local subnode id.
name	string	必需	只读。Short reported label.
kind	string	必需	只读。Reported step kind (for example a tool or model call); free-form and node-owned.
status	"error" | "success" | "unknown" | "planned" | "running" | "cancelled" | "skipped" | undefined	可省略	只读。Reported lifecycle status; omission means the node did not report one.
usedModel	boolean | undefined	可省略	只读。This step's own reported model use, never a descendant rollup.
startedAtMs	number | undefined	可省略	只读。Reported start instant in epoch milliseconds.
endedAtMs	number | undefined	可省略	只读。Reported end instant in epoch milliseconds; only meaningful for terminal statuses.
nextStepIds	readonly string[] | undefined	可省略	只读。Reported successor step ids, for display only.
caseId	string | undefined	可省略	只读。Reported case or variant id, interpreted by the App.
summary	string | undefined	可省略	只读。Reported one-line summary.

使用示例

• 过程监听与节点报告：App 订阅 Core 执行事实；节点报告自身 usedModel，并用实例式子日志先记意图、再补结果，Loop 负责身份和日志。

监听任务经过的节点与模型事件

入门 · 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, execution: {
  observe: { event(event) { console.log(event.type, event.eventId); } },
} });
console.log(await agent.run({ name: 'Ivan' }));

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, execution: {
        observe: { event(event) { console.log(event.type, event.eventId); } },
    } });
console.log(await agent.run({ name: 'Ivan' }));

节点执行时报告业务阶段

配置 · Node.js

节点只报告它知道的事实；Core 负责节点身份和执行关联。

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: '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' }));

JavaScript

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: {
        observe: { event(event) { console.log(event.type); } },
    } });
console.log(await agent.run({ name: 'Ivan' }));
