ReplyPreviewTool
SUPPORT · interface · Type contract
Capability declaration used to derive preview rules.
Omitted preview means the capability never previews, so previewing is an explicit opt-in.
Import
ts
import type { ReplyPreviewTool } from '@jangts/agent-core/support';js
/** @typedef {import('@jangts/agent-core/support').ReplyPreviewTool} ReplyPreviewTool */Other public entry points:@jangts/agent-core/support, @jangts/agent-core/support/model.
Definition
ts
interface ReplyPreviewToolField structure
| Field | Type | Required | Description |
|---|---|---|---|
id | string | Required | Read-only. Capability ID, which must equal the native function wire name used for transport. |
jsonSchema | Readonly<Record<string, unknown>> | Required | Read-only. Input schema used to prove that preview and eligibility paths really exist. |
preview | true | Omit<ReplyPreviewRule, "stageId" | "toolId"> | undefined | Optional | Read-only. Explicit preview opt-in: true uses the default text/bubble paths, an object narrows the paths and eligibility, and omission means the capability never previews. |
Examples
- Generate preview rules from tool and stage declarations: Reuse the actual Schema and stage references to generate rules only for tools that are explicitly allowed to be displayed.
Explicitly mark a text-only stage
Beginner · Node.js
ts
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);js
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);Reuse the Schema and stage references of structured tools
Configuration · Node.js
A real App should project these two arrays from the tools and stage declarations it has already registered; this example uses minimal static data to show the required fields.
ts
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);js
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);
