ReplyPreviewRule

SUPPORT · interface · 类型合同

One projection rule: which stage/capability it matches and which prose fields may be shown.

A rule without toolId may only match a registered plain-text stage.

导入

TypeScript

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

JavaScript

/** @typedef {import('@jangts/agent-core/support').ReplyPreviewRule} ReplyPreviewRule */

其他公开入口：@jangts/agent-core/support。

定义

interface ReplyPreviewRule

字段结构

字段	类型	必需	说明
toolId	string | undefined	可省略	Native function wire name. Omit only for a registered plain-text stage.
stageId	string | undefined	可省略	Restrict the rule to one stage; omitted matches any stage producing this capability.
paths	readonly (readonly string[])[] | undefined	可省略	JSON paths to project, where * matches any array index; defaults to text/bubble paths.
when	{ path: readonly string[]; values: readonly string[]; } | undefined	可省略	Presentation eligibility from a complete string field in the same proposal.

使用示例

• 正文预览：有序输出，不代替最终接受：按已登记的 stage/tool/字段路径提取可展示正文，拒绝把控制提议当作已执行结果。

为纯文本阶段增加预览

入门 · Node.js

TypeScript

import { ModelRunner, Support } from '@jangts/agent-core';
const preview = Support.createReplyPreview({ rules: [{ stageId: 'reply' }],
  sink: bubbles => { console.log('preview', bubbles); },
});
const runner = new ModelRunner({ provider: { async *stream() { yield '你好'; yield '，Core'; } }, sink: { output: preview } });
console.log((await runner.invoke({ input: '你好', stageId: 'reply' })).value);

JavaScript

import { ModelRunner, Support } from '@jangts/agent-core';
const preview = Support.createReplyPreview({ rules: [{ stageId: 'reply' }],
    sink: bubbles => { console.log('preview', bubbles); },
});
const runner = new ModelRunner({ provider: { async *stream() { yield '你好'; yield '，Core'; } }, sink: { output: preview } });
console.log((await runner.invoke({ input: '你好', stageId: 'reply' })).value);

只允许明确正文协议的可展示字段

配置 · Node.js

规则必须对应 App 实际登记的 reply Tool 与 Schema，配置预览本身不创建模型 Tool。

TypeScript

import { Support } from '@jangts/agent-core';
const preview = Support.createReplyPreview({
  rules: [{ stageId: 'reply', toolId: 'reply', paths: [['answer'], ['bubbles', '*']],
    when: { path: ['kind'], values: ['reply'] } }],
  sink: async bubbles => { console.log('当前暂态正文', bubbles); },
  maxChars: 4000,
});
console.log(typeof preview);

JavaScript

import { Support } from '@jangts/agent-core';
const preview = Support.createReplyPreview({
    rules: [{ stageId: 'reply', toolId: 'reply', paths: [['answer'], ['bubbles', '*']],
            when: { path: ['kind'], values: ['reply'] } }],
    sink: async (bubbles) => { console.log('当前暂态正文', bubbles); },
    maxChars: 4000,
});
console.log(typeof preview);
