ProtocolReason

KIT · type · 类型合同

Lazy rejection wording: a fixed message, a pre-built error, or a factory bound to the value.

导入

TypeScript

import type { ProtocolReason } from '@jangts/agent-core/kits/interaction';

JavaScript

/** @typedef {import('@jangts/agent-core/kits/interaction').ProtocolReason} ProtocolReason */

其他公开入口：@jangts/agent-core、@jangts/agent-core/types、@jangts/agent-core/structs、@jangts/agent-core/kits/interaction、@jangts/agent-core/kits。

定义

type ProtocolReason<Value, Args extends unknown[]> = Error | string | ((value: Value, ...args: Args) => Error | string);

泛型参数

类型参数	约束	默认类型
Value	—	—
Args	unknown[]	—

联合分支结构

使用示例

• Interaction：声明命令并绑定本地处理器：命令的字段、目的、选择器、检查和 handler 来自同一声明，模型不能添加可执行处理器。

先定义一种说明命令并校验

入门 · Node.js

TypeScript

import { Interaction } from '@jangts/agent-core/kits/interaction';
const protocol = Interaction.define({
  commandField: 'type', commands: {
    reply: { category: 'presentation', description: '展示已确认说明', fields: { text: { required: true, jsonSchema: { type: 'string' } } },
      checks: [{ occur: value => typeof value.text !== 'string', error: 'text 必须是字符串' }] },
  },
});
console.log(protocol.receive({ type: 'reply', text: '普通对象也能实现接口。' }));
console.log(protocol.modelJsonSchema);

JavaScript

import { Interaction } from '@jangts/agent-core/kits/interaction';
const protocol = Interaction.define({
    commandField: 'type', commands: {
        reply: { category: 'presentation', description: '展示已确认说明', fields: { text: { required: true, jsonSchema: { type: 'string' } } },
            checks: [{ occur: value => typeof value.text !== 'string', error: 'text 必须是字符串' }] },
    },
});
console.log(protocol.receive({ type: 'reply', text: '普通对象也能实现接口。' }));
console.log(protocol.modelJsonSchema);

保留同一协议，增加完整 handler 绑定

配置 · Node.js

TypeScript

import { Interaction } from '@jangts/agent-core/kits/interaction';
const protocol = Interaction.define({
  commandField: 'type', commands: {
    reply: { category: 'presentation', description: '展示已确认说明', fields: { text: { required: true, jsonSchema: { type: 'string' } } }, checks: [{ occur: value => typeof value.text !== 'string', error: 'text 必须是字符串' }] },
    unavailable: { category: 'receipt', description: '说明资料不可用', fields: {} },
  },
});
const dispatcher = Interaction.bind(protocol, {
  reply: value => '说明：' + String(value.text),
  unavailable: () => '资料暂不可用',
});
console.log(dispatcher.dispatch({ type: 'reply', text: '普通对象也能实现接口。' }, undefined));
console.log(dispatcher.catalog);

JavaScript

import { Interaction } from '@jangts/agent-core/kits/interaction';
const protocol = Interaction.define({
    commandField: 'type', commands: {
        reply: { category: 'presentation', description: '展示已确认说明', fields: { text: { required: true, jsonSchema: { type: 'string' } } }, checks: [{ occur: value => typeof value.text !== 'string', error: 'text 必须是字符串' }] },
        unavailable: { category: 'receipt', description: '说明资料不可用', fields: {} },
    },
});
const dispatcher = Interaction.bind(protocol, {
    reply: value => '说明：' + String(value.text),
    unavailable: () => '资料暂不可用',
});
console.log(dispatcher.dispatch({ type: 'reply', text: '普通对象也能实现接口。' }, undefined));
console.log(dispatcher.catalog);

相关策略源码

• 字段、检查与模型 Schema
• 选择器与命令接收
• 按已校验命令绑定本地 handler
