RegisteredModelTool

CORE · type · 类型合同

Frozen snapshot stored by a registry after schema validation.

导入

TypeScript

import type { RegisteredModelTool } from '@jangts/agent-core';

JavaScript

/** @typedef {import('@jangts/agent-core').RegisteredModelTool} RegisteredModelTool */

其他公开入口：@jangts/agent-core、@jangts/agent-core/types、@jangts/agent-core/structs。

定义

类型： RegisteredModelTool<Output>

类型表达式

type RegisteredModelTool<Output = unknown> = Readonly<ModelTool<unknown, Output>>;

泛型参数

类型参数	约束	默认类型
Output	—	unknown

字段结构

字段	类型	必需	说明
id	string	必需	只读。Unique id within its registry; never blank.
description	string	必需	只读。Model-visible description explaining when the capability applies.
inputSchema	SchemaAdapter<unknown>	必需	只读。Schema describing the arguments; must be an object schema.
active	ToolCondition<any> | undefined	可省略	只读。Omitted means active. Authorization remains a separate execution boundary.
asIntent	AsIntent<any> | undefined	可省略	只读。Omitted means this tool is not advertised by withIntent().
resolve	(input: unknown, context: Readonly<{ stageId: string; }>) => Output	必需	Converts validated arguments into the value handed back to the caller. Runs inside the model call, so it must return synchronously; throwing rejects the selection.

成员详情

resolve

Converts validated arguments into the value handed back to the caller.

Runs inside the model call, so it must return synchronously; throwing rejects the selection.

RegisteredModelTool.resolve(input: unknown, context: Readonly<{ stageId: string; }>): Output

Converts validated arguments into the value handed back to the caller.

Runs inside the model call, so it must return synchronously; throwing rejects the selection.

参数	类型	传递	说明
input	unknown	必需	—
context	Readonly<{ stageId: string; }>	必需	—

context 的字段

字段	类型	必需	说明
stageId	string	必需	见类型定义及调用场景。

返回： Output。

等待后的值： Awaited<Output>。

使用示例

• 模型 Tool 与传输：完整校验后才得到类型化选择：Tool 定义提供 Schema 与 resolver；传输将 wire 输出翻译为统一的模型选择合同。
• 工具最佳实践：一份定义生成模型 Tool 与执行运行时：把 Schema、授权、执行和输出校验登记一次，按请求绑定 App，避免维护两份工具清单。
• 模型传输与阶段投影：从 Tool 定义生成封存目录与阶段投影，原生函数和 JSON 适配复用同一 Tool 合同。

入门 · Node.js

TypeScript

import { ModelToolRegistry } from '@jangts/agent-core';
const inputSchema = { jsonSchema: { type: 'object', properties: {}, additionalProperties: false },
  parse(value: unknown) {
    if (!value || typeof value !== 'object' || Array.isArray(value) || Object.keys(value).length) throw new Error('需要空对象');
    return {};
  } };
const tools = new ModelToolRegistry([
  { id: 'greet', description: '回答问候', inputSchema, resolve: () => 'greet' },
  { id: 'status', description: '查询状态', inputSchema, resolve: () => 'status' },
]).seal();
console.log(tools.resolve({ toolId: 'status', input: {} }, { stageId: 'recognize' }));

JavaScript

import { ModelToolRegistry } from '@jangts/agent-core';
const inputSchema = { jsonSchema: { type: 'object', properties: {}, additionalProperties: false },
    parse(value) {
        if (!value || typeof value !== 'object' || Array.isArray(value) || Object.keys(value).length)
            throw new Error('需要空对象');
        return {};
    } };
const tools = new ModelToolRegistry([
    { id: 'greet', description: '回答问候', inputSchema, resolve: () => 'greet' },
    { id: 'status', description: '查询状态', inputSchema, resolve: () => 'status' },
]).seal();
console.log(tools.resolve({ toolId: 'status', input: {} }, { stageId: 'recognize' }));

仅向一个阶段投影允许的子集

配置 · Node.js

TypeScript

import { ModelToolRegistry, Support } from '@jangts/agent-core';
const schema = Support.defineSchema({ jsonSchema: { type: 'object', properties: {} },
  parse(value: unknown) { if (!value || typeof value !== 'object' || Array.isArray(value)) throw new TypeError('需要对象'); return {}; } });
const registry = new ModelToolRegistry([
  { id: 'greet', description: '问候', inputSchema: schema, resolve: () => 'greet' },
  { id: 'status', description: '状态', inputSchema: schema, resolve: () => 'status' },
]).seal();
const readOnly = registry.select(['status']);
const transport = Support.createModelTransport({ id: 'recognize', tools: readOnly });
console.log(transport.id, readOnly.ids());

JavaScript

import { ModelToolRegistry, Support } from '@jangts/agent-core';
const schema = Support.defineSchema({ jsonSchema: { type: 'object', properties: {} },
    parse(value) { if (!value || typeof value !== 'object' || Array.isArray(value))
        throw new TypeError('需要对象'); return {}; } });
const registry = new ModelToolRegistry([
    { id: 'greet', description: '问候', inputSchema: schema, resolve: () => 'greet' },
    { id: 'status', description: '状态', inputSchema: schema, resolve: () => 'status' },
]).seal();
const readOnly = registry.select(['status']);
const transport = Support.createModelTransport({ id: 'recognize', tools: readOnly });
console.log(transport.id, readOnly.ids());
