SUPPORT · constant · 运行时值

导入

TypeScript

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

JavaScript

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

其他公开入口：@jangts/agent-core/support、@jangts/agent-core/support/context。

定义

const contextSelectionCatalog: { sequence: { validate: () => void; choose: ({ candidates }: SelectionInput) => Promise<SelectionResult>; }; fixed: { validate: (selection: ContextSelection) => void; choose: ({ selection, candidates }: SelectionInput) => Promise<SelectionResult>; }; auto: { validate: (selection: ContextSelection) => void; choose: ({ selection, candidates }: SelectionInput) => Promise<SelectionResult>; }; model: { validate: (selection: ContextSelection, selectors: readonly ContextSelector[]) => void; choose: (input: SelectionInput) => Promise<SelectionResult>; }; }

字段结构

字段	类型	必需	说明
sequence	{ validate: () => void; choose: ({ candidates }: SelectionInput) => Promise<SelectionResult>; }	必需	见类型定义及调用场景。
fixed	{ validate: (selection: ContextSelection) => void; choose: ({ selection, candidates }: SelectionInput) => Promise<SelectionResult>; }	必需	见类型定义及调用场景。
auto	{ validate: (selection: ContextSelection) => void; choose: ({ selection, candidates }: SelectionInput) => Promise<SelectionResult>; }	必需	见类型定义及调用场景。
model	{ validate: (selection: ContextSelection, selectors: readonly ContextSelector[]) => void; choose: (input: SelectionInput) => Promise<SelectionResult>; }	必需	见类型定义及调用场景。

使用示例

• 选择缩减步骤：顺序、固定、自动或模型：一套类型化策略表达多种场景，保留精确参数与 App 自定义选择。

按已登记顺序处理

入门 · Node.js

TypeScript

import { Support } from '@jangts/agent-core';
Support.validateContextSelection({ mode: 'sequence' }, []);
console.log(Object.keys(Support.contextSelectionCatalog));

JavaScript

import { Support } from '@jangts/agent-core';
Support.validateContextSelection({ mode: 'sequence' }, []);
console.log(Object.keys(Support.contextSelectionCatalog));

按场景选择策略并精确覆盖

配置 · Node.js

TypeScript

import { Support } from '@jangts/agent-core';
const localOnly = { mode: 'fixed' as const, kind: 'trim' as const };
const preserveMore = { mode: 'auto' as const, maxTrimLossRatio: 0.1, reserveCalls: 2 };
Support.validateContextSelection(localOnly, []);
Support.validateContextSelection(preserveMore, []);
console.log(localOnly, preserveMore);

JavaScript

import { Support } from '@jangts/agent-core';
const localOnly = { mode: 'fixed', kind: 'trim' };
const preserveMore = { mode: 'auto', maxTrimLossRatio: 0.1, reserveCalls: 2 };
Support.validateContextSelection(localOnly, []);
Support.validateContextSelection(preserveMore, []);
console.log(localOnly, preserveMore);
