defineEvidenceChecklist

KIT · function · 运行时值

Compile a reusable completion checklist over actual observations.

A requirement is satisfied when at least one observation satisfies the provider registered for its kind; isComplete requires every requirement to be satisfied, and missing returns those that are not. Hosts define evidence semantics.

导入

import { defineEvidenceChecklist } from '@jangts/agent-core/kits/evidence';

调用

defineEvidenceChecklist<Observation, Requirement extends EvidenceRequirement>(definitions: readonly EvidenceProvider<Observation, Requirement>[]): Readonly<{ isSatisfied: (request: { observations: readonly Observation[]; requirement: Requirement; }) => boolean; isComplete: (request: { observations: readonly Observation[]; requirements: readonly Requirement[]; }) => boolean; missing({ observations, requirements, }: { observations: readonly Observation[]; requirements: readonly Requirement[]; }): Requirement[]; }>

参数	类型	传递	说明
definitions	readonly EvidenceProvider<Observation, Requirement>[]	必需	—

返回： Readonly<{ isSatisfied: (request: { observations: readonly Observation[]; requirement: Requirement; }) => boolean; isComplete: (request: { observations: readonly Observation[]; requirements: readonly Requirement[]; }) => boolean; missing({ observations, requirements, }: { observations: readonly Observation[]; requirements: readonly Requirement[]; }): Requirement[]; }>。

返回值结构

字段	类型	必需	说明
isSatisfied	(request: { observations: readonly Observation[]; requirement: Requirement; }) => boolean	必需	见类型定义及调用场景。
isComplete	(request: { observations: readonly Observation[]; requirements: readonly Requirement[]; }) => boolean	必需	见类型定义及调用场景。
missing	({ observations, requirements, }: { observations: readonly Observation[]; requirements: readonly Requirement[]; }) => Requirement[]	必需	见类型定义及调用场景。

使用示例

• Evidence：用真实观察检查完成性：用 App 定义的证据语义检查需求，避免把模型的“完成了”当成真实回执。

TypeScript

import { Evidence } from '@jangts/agent-core/kits/evidence';
type Observation = { sourceId: string; read: boolean };
type Requirement = { id: string; kind: 'source-read'; sourceId: string };
const checklist = Evidence.defineEvidenceChecklist<Observation, Requirement>([
  { kind: 'source-read', description: '资料读取已成功', isSatisfied: (seen, need) => seen.read && seen.sourceId === need.sourceId },
]);
console.log(checklist.isComplete({ observations: [{ sourceId: 'manual', read: true }], requirements: [{ id: 'need-manual', kind: 'source-read', sourceId: 'manual' }] }));

JavaScript

import { Evidence } from '@jangts/agent-core/kits/evidence';
const checklist = Evidence.defineEvidenceChecklist([
    { kind: 'source-read', description: '资料读取已成功', isSatisfied: (seen, need) => seen.read && seen.sourceId === need.sourceId },
]);
console.log(checklist.isComplete({ observations: [{ sourceId: 'manual', read: true }], requirements: [{ id: 'need-manual', kind: 'source-read', sourceId: 'manual' }] }));
