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
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);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.
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);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);
