入门 · Node.js
ts
import { assembleFragments } from '@jangts/agent-core/context';
const input = assembleFragments([{ id: 'question', sourceId: 'request', trust: 'user',
lifetime: 'turn', maxChars: 1000, role: 'user', value: '现在服务状态怎样？' }], 2000);
console.log(input.messages, input.fragmentUsage);js
import { assembleFragments } from '@jangts/agent-core/context';
const input = assembleFragments([{ id: 'question', sourceId: 'request', trust: 'user',
lifetime: 'turn', maxChars: 1000, role: 'user', value: '现在服务状态怎样？' }], 2000);
console.log(input.messages, input.fragmentUsage);增加候选计划与最终审计
配置 · Node.js
可变片段列表为空，表示不允许修改原片段；不会自动授权一个压缩步骤。
ts
import { assembleContextPlan } from '@jangts/agent-core/context';
import type { ContextFragment } from '@jangts/agent-core/types';
const fragments: ContextFragment[] = [{ id: 'question', sourceId: 'request', trust: 'user',
lifetime: 'turn', maxChars: 1000, role: 'user', value: '现在服务状态怎样？' }];
const input = assembleContextPlan({ fragments, originalFragments: fragments, mutableFragmentIds: [], maxInputChars: 2000 });
console.log(input.inputChars);js
