defineAnswerCheckCatalog

KIT · function · Runtime value

Compile a checker catalog.

A checker may return a replacement value; it is threaded into the next checker, so the selected ids behave like an ordered chain rather than independent assertions.

Import

TypeScript

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

Return value structure

Field	Type	Required	Description
check	(request: { checkIds: readonly string[]; value: Value; }, context: OperationContext<App>) => AnswerCheck<Value>	Required	See the type definition and usage context.
definitions	readonly Readonly<{ id: string; check: (value: Value, context: OperationContext<App>) => CheckResult<Value>; }>[]	Required	Read-only. Definitions in registration order; each entry is frozen by the implementation.
ids	() => readonly string[]	Required	Ids in the same order as definitions.
values	() => IterableIterator<Readonly<{ id: string; check: (value: Value, context: OperationContext<App>) => CheckResult<Value>; }>>	Required	See the type definition and usage context.
entries	() => IterableIterator<readonly [string, Readonly<{ id: string; check: (value: Value, context: OperationContext<App>) => CheckResult<Value>; }>]>	Required	See the type definition and usage context.
has	(id: string) => boolean	Required	See the type definition and usage context.
get	(id: string) => Readonly<{ id: string; check: (value: Value, context: OperationContext<App>) => CheckResult<Value>; }> | undefined	Required	Returns the definition or undefined; the caller decides whether absence is an error.
require	(id: string) => Readonly<{ id: string; check: (value: Value, context: OperationContext<App>) => CheckResult<Value>; }>	Required	Returns the definition or throws; use when the id is a required reference.

Examples

• Answering catalog: tasks, source reads, and check references: One task definition ties together the input Schema, reader, output, and check, with real references verified at assembly.

Register one read task for explanatory material

Beginner · Node.js

TypeScript

import { Answering } from '@jangts/agent-core/kits/answering';
import { Presentation } from '@jangts/agent-core/kits/presentation';
const readers = Answering.defineAnswerReaderCatalog([{ id: 'manual', read: (input: string) => ({ question: input, source: 'Agent Core 允许普通对象节点。' }) }]);
const checks = Answering.defineAnswerCheckCatalog<string, {}>([]);
const outputs = Presentation.defineOutputCatalog([{ id: 'reply', kind: 'text', fields: [{ id: 'text', owner: 'generated' }] }]);
const tasks = Answering.defineAnswerTaskCatalog([
  { id: 'explain', description: '根据说明资料解释接口', readerId: 'manual', outputId: 'reply', goalIds: ['explain'], checkIds: [], metadata: {},
    inputSchema: { jsonSchema: { type: 'string' }, parse(value: unknown) { if (typeof value !== 'string') throw new Error('需要问题'); return value; } } },
], { readers, checks, outputs });
console.log(tasks.read({ taskId: 'explain', input: '如何定义节点？' }, { app: {}, signal: new AbortController().signal }));

                throw new Error('需要问题'); return value; } } },
], { readers, checks, outputs });
console.log(tasks.read({ taskId: 'explain', input: '如何定义节点？' }, { app: {}, signal: new AbortController().signal }));

Add check references to the same task and check the generated result
