interface ContextStrategy字段结构
| 字段 | 类型 | 必需 | 说明 |
|---|---|---|---|

- 从历史语义生成处理策略：复用片段身份与硬预算，生成 recent 或 continuity 的完整步骤和引用。
复用已有片段生成最近历史策略
入门 · Node.js
ts
import { Support } from '@jangts/agent-core';
const fragment = { id: 'history', maxChars: 4000 };
const strategy = Support.createContextStrategy({ kind: 'recent', fragment, field: 'messages' });
console.log(strategy.policy, strategy.compressors);js
import { Support } from '@jangts/agent-core';
const fragment = { id: 'history', maxChars: 4000 };
const strategy = Support.createContextStrategy({ kind: 'recent', fragment, field: 'messages' });
console.log(strategy.policy, strategy.compressors);同一配置增加保留组数与目标大小
