AnswerItem

KIT · interface · Type contract

One unit an answer batch must produce.

Definition

interface AnswerItem<Data>

Type parameters

Type parameter	Constraint	Default type
Data	—	—

Field structure

Field	Type	Required	Description
id	string	Required	Read-only. Unique item id inside the batch; also the key used for values and repairs.
inputIds	readonly string[]	Required	Read-only. Input ids this item answers; every batch input must be covered exactly once overall.
data	Data	Required	Read-only. App-owned data the generator and readers consume.
sourceStatus	"unavailable" | "ready" | "conflict"	Required	Read-only. Availability of the item's source material; anything but ready cannot be answered.

Examples

• Answering Flow: item-by-item generation, review, and local repair: Preserve coverage relationships over a split question batch and repair failing items without regenerating the ones that passed.

First handle one question that has a source

Beginner · Node.js

The offline example uses already-read body text directly to show the flow contract; when switching to model generation, the same generate port still applies.

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);

Keep run unchanged and add review plus one local repair

Configuration · Node.js

The example triggers one real local repair with an empty draft; production review should rely on real evidence instead of substituting string equality for semantic review.

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);
