defineAnswerFlow

KIT · function · 运行时值

Compile a reusable answer workflow.

Reusable answer workflow. Requests own cells and repair budgets; models remain caller-owned. The flow runs at most maxRepairs + 1 rounds: one generation pass, then one repair round per failing item set, and finally an explicit accepted/fallback/blocked result per item.

导入

TypeScript

import { defineAnswerFlow } from '@jangts/agent-core/kits/answering';

definition 的字段

字段	类型	必需	说明
maxItems	number	必需	只读。Maximum items in one batch; must be a positive integer.
maxRepairs	number	必需	只读。Repair rounds; the flow runs at most maxRepairs + 1 rounds in total.
reviewPolicy	"required" | "off" | "optional" | undefined	可省略	只读。Review policy; defaults to optional, required blocks on an unresolved review.
canInvoke	(context: OperationContext<App>) => boolean	必需	Request-level budget guard; must return boolean synchronously.
generate	(input: { readonly items: readonly AnswerItem<Data>[]; readonly repairs?: ReadonlyMap<string, readonly AnswerIssue[]>; readonly previous?: ReadonlyMap<string, Value> | undefined; }, context: OperationContext<App>) => Promise<ReadonlyMap<string, Value>>	必需	Produces values for the items that still need one. repairs carries the issues of a failed attempt and previous its rejected values.
check	(input: { readonly item: AnswerItem<Data>; readonly value: Value; }, context: OperationContext<App>) => AnswerCheck<Value>	必需	Local check for one generated value; must return synchronously.
review	((input: { readonly items: readonly { item: AnswerItem<Data>; value: Value; }[]; }, context: OperationContext<App>) => Promise<ReadonlyMap<string, AnswerCheck<Value>>>) | undefined	可省略	Batch review; returns one check per reviewed item and must cover the submitted items.
fallback	(input: { readonly item: AnswerItem<Data>; readonly issues: readonly AnswerIssue[]; }, context: OperationContext<App>) => RecoveryResult<Value>	必需	Last resort for a failed item; handled supplies a replacement value.
observe	((input: { readonly stageId: string; readonly results: readonly AnswerResult<Data, Value>[]; }, context: OperationContext<App>) => MaybePromise<void>) | undefined	可省略	Observes a stage outcome; failures must not affect the flow result.

返回： Readonly<{ run(request: { inputIds: readonly string[]; items: readonly AnswerItem<Data>[]; }, context: OperationContext<App>): Promise<AnswerResult<Data, Value>[]>; }>。

返回值结构

字段	类型	必需	说明
run	(request: { inputIds: readonly string[]; items: readonly AnswerItem<Data>[]; }, context: OperationContext<App>) => Promise<AnswerResult<Data, Value>[]>	必需	Run one answer batch.

使用示例

• Answering Flow：逐项生成、复核与局部修正：对已拆分的问题批次保留覆盖关系，修复失败项，不重新生成已经通过的项。

先处理一个有来源的说明问题

入门 · Node.js

离线示例直接使用已读正文，展示流程合同；换成模型生成时仍用同一个 generate 端口。

TypeScript

import { Answering } from '@jangts/agent-core/kits/answering';
const flow = Answering.defineAnswerFlow<{ source: string }, string, {}>({
  maxItems: 4, maxRepairs: 0, reviewPolicy: 'off', canInvoke: () => true,
  async generate({ items }) { return new Map(items.map(item => [item.id, item.data.source])); },
  check: ({ value }) => ({ status: value.trim() ? 'passed' : 'failed', issues: [] }),
  fallback: () => ({ handled: false }),
});
const result = await flow.run({ inputIds: ['question-1'], items: [{ id: 'explain', inputIds: ['question-1'], sourceStatus: 'ready', data: { source: '普通对象可以实现节点合同。' } }] }, { app: {}, signal: new AbortController().signal });
console.log(result[0].status, result[0].value);

JavaScript

import { Answering } from '@jangts/agent-core/kits/answering';
const flow = Answering.defineAnswerFlow({
    maxItems: 4, maxRepairs: 0, reviewPolicy: 'off', canInvoke: () => true,
    async generate({ items }) { return new Map(items.map(item => [item.id, item.data.source])); },
    check: ({ value }) => ({ status: value.trim() ? 'passed' : 'failed', issues: [] }),
    fallback: () => ({ handled: false }),
});
const result = await flow.run({ inputIds: ['question-1'], items: [{ id: 'explain', inputIds: ['question-1'], sourceStatus: 'ready', data: { source: '普通对象可以实现节点合同。' } }] }, { app: {}, signal: new AbortController().signal });
console.log(result[0].status, result[0].value);

保持 run 不变，增加复核和一次局部修正

配置 · Node.js

示例以空草稿触发一次真实局部修正；生产 review 应依据真实证据，不用字符串等号代替语义复核。

TypeScript

import { Answering } from '@jangts/agent-core/kits/answering';
const flow = Answering.defineAnswerFlow<{ source: string }, string, {}>({
  maxItems: 4, maxRepairs: 1, reviewPolicy: 'required', canInvoke: () => true,
  async generate({ items, repairs }) { return new Map(items.map(item => [item.id, repairs?.has(item.id) ? item.data.source : ''])); },
  check: ({ value }) => ({ status: value.trim() ? 'passed' : 'failed', issues: value.trim() ? [] : [{ code: 'EMPTY', message: '需要非空回答' }] }),
  async review({ items }) { return new Map(items.map(({ item, value }) => [item.id, { status: value === item.data.source ? 'passed' as const : 'failed' as const, issues: [] }])); },
  fallback: () => ({ handled: true, value: '当前资料不足，暂时无法回答。' }),
});
const result = await flow.run({ inputIds: ['question-1'], items: [{ id: 'explain', inputIds: ['question-1'], sourceStatus: 'ready', data: { source: '普通对象可以实现节点合同。' } }] }, { app: {}, signal: new AbortController().signal });
console.log(result[0].status, result[0].checks);

JavaScript

import { Answering } from '@jangts/agent-core/kits/answering';
const flow = Answering.defineAnswerFlow({
    maxItems: 4, maxRepairs: 1, reviewPolicy: 'required', canInvoke: () => true,
    async generate({ items, repairs }) { return new Map(items.map(item => [item.id, repairs?.has(item.id) ? item.data.source : ''])); },
    check: ({ value }) => ({ status: value.trim() ? 'passed' : 'failed', issues: value.trim() ? [] : [{ code: 'EMPTY', message: '需要非空回答' }] }),
    async review({ items }) { return new Map(items.map(({ item, value }) => [item.id, { status: value === item.data.source ? 'passed' : 'failed', issues: [] }])); },
    fallback: () => ({ handled: true, value: '当前资料不足，暂时无法回答。' }),
});
const result = await flow.run({ inputIds: ['question-1'], items: [{ id: 'explain', inputIds: ['question-1'], sourceStatus: 'ready', data: { source: '普通对象可以实现节点合同。' } }] }, { app: {}, signal: new AbortController().signal });
console.log(result[0].status, result[0].checks);

先验证多问题覆盖，防止遗漏输入

扩展 · Node.js

TypeScript

import { Answering } from '@jangts/agent-core/kits/answering';
const items = [
  { id: 'define', inputIds: ['q1'], sourceStatus: 'ready' as const, data: { source: '定义节点' } },
  { id: 'run', inputIds: ['q2'], sourceStatus: 'unavailable' as const, data: { source: '' } },
];
Answering.validateAnswerBatch(['q1', 'q2'], items, 4);
console.log('两个问题均有明确处理项，包括资料不可用的项。');

JavaScript

import { Answering } from '@jangts/agent-core/kits/answering';
const items = [
    { id: 'define', inputIds: ['q1'], sourceStatus: 'ready', data: { source: '定义节点' } },
    { id: 'run', inputIds: ['q2'], sourceStatus: 'unavailable', data: { source: '' } },
];
Answering.validateAnswerBatch(['q1', 'q2'], items, 4);
console.log('两个问题均有明确处理项，包括资料不可用的项。');
