createReplyPreviewRules

SUPPORT · function · 运行时值

Generate frozen preview rules from capability and stage declarations.

Capabilities without preview metadata are skipped even when their stage opts in. Default paths are text and bubbles[*], each kept only when the capability schema declares it.

导入

TypeScript

import { createReplyPreviewRules } from '@jangts/agent-core/support';

createReplyPreviewRules(options: { readonly stages: readonly ReplyPreviewStage[]; readonly tools: readonly ReplyPreviewTool[]; }): readonly ReplyPreviewRule[]

Generate frozen preview rules from capability and stage declarations.

Capabilities without preview metadata are skipped even when their stage opts in. Default paths are text and bubbles[*], each kept only when the capability schema declares it.

参数	类型	传递	说明
options	{ readonly stages: readonly ReplyPreviewStage[]; readonly tools: readonly ReplyPreviewTool[]; }	必需	—

options 的字段

字段	类型	必需	说明
stages	readonly ReplyPreviewStage[]	必需	只读。见类型定义及调用场景。
tools	readonly ReplyPreviewTool[]	必需	只读。见类型定义及调用场景。

返回： readonly ReplyPreviewRule[]。

使用示例

• 从 Tool 与阶段声明生成预览规则：复用实际 Schema 与阶段引用，只为明确允许展示的 Tool 生成规则。

明确标记纯文本阶段

入门 · Node.js

TypeScript

import { Support } from '@jangts/agent-core';
const rules = Support.createReplyPreviewRules({ stages: [{ id: 'reply', preview: 'text' }], tools: [] });
const preview = Support.createReplyPreview({ rules, sink: bubbles => { console.log(bubbles); } });
console.log(typeof preview);

JavaScript

import { Support } from '@jangts/agent-core';
const rules = Support.createReplyPreviewRules({ stages: [{ id: 'reply', preview: 'text' }], tools: [] });
const preview = Support.createReplyPreview({ rules, sink: bubbles => { console.log(bubbles); } });
console.log(typeof preview);

复用结构化 Tool 的 Schema 与阶段引用

配置 · Node.js

真实 App 应从它已经登记的 Tool 和阶段声明投影这两个数组；本例用最小静态资料展示所需字段。

TypeScript

import { Support } from '@jangts/agent-core';
const tools = [{ id: 'reply', jsonSchema: { type: 'object', properties: { answer: { type: 'string' } } },
  preview: { paths: [['answer']] } }];
const rules = Support.createReplyPreviewRules({
  stages: [{ id: 'respond', toolIds: ['reply'], preview: 'tools' }], tools,
});
const preview = Support.createReplyPreview({ rules, sink: bubbles => { console.log(bubbles); } });
console.log(rules, typeof preview);

JavaScript

import { Support } from '@jangts/agent-core';
const tools = [{ id: 'reply', jsonSchema: { type: 'object', properties: { answer: { type: 'string' } } },
        preview: { paths: [['answer']] } }];
const rules = Support.createReplyPreviewRules({
    stages: [{ id: 'respond', toolIds: ['reply'], preview: 'tools' }], tools,
});
const preview = Support.createReplyPreview({ rules, sink: bubbles => { console.log(bubbles); } });
console.log(rules, typeof preview);
