定义

泛型参数

类型参数	约束	默认类型
Result	—	—
Id	string	string

调用

createStageModelTransport<Result, const Id extends string = string>(registration: ModelStageTransportRegistration<Result> & { readonly id: Id; }): ModelTransportDefinition<Result> & { readonly id: Id; }

Build a transport that projects a capability source through declared stage references.

类型参数	约束	默认类型
Result	—	—
Id	string	string

参数	类型	传递	说明
registration	ModelStageTransportRegistration<Result> & { readonly id: Id; }	必需	—

registration 的字段

字段	类型	必需	说明
stages	readonly { readonly id: string; readonly toolIds: readonly string[]; }[]	必需	只读。Declared stages; each id is unique and lists non-empty, unique capability ids.
id	Id	必需	Transport id used by call requests and reported in diagnostic events.
tools	ModelToolSource<Result> | ((stage: string) => ModelToolSource<Result>)	必需	Static capability source, or a factory that selects tools per stage.
adapter	ModelInteractionAdapter | undefined	可省略	Wire-format adapter; defaults to native function calling.
options	Pick<ModelOptions, "temperature"> | undefined	可省略	Sampling defaults this transport contributes to every call.
requireStrictArguments	boolean | undefined	可省略	Reject the registration when the chosen adapter cannot enforce strict arguments.

返回： ModelTransportDefinition<Result> & { readonly id: Id; }。

返回值结构

字段	类型	必需	说明
id	Id	必需	只读。Transport id used by call requests and reported in diagnostics.
prepare	(stageId: string) => PreparedModelTransport<Result>	必需	Builds the prepared transport for stageId; must not spend a call by itself.

使用示例

• 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。

创建具名文本传输

入门 · Node.js

TypeScript

import { ModelRunner, Support } from '@jangts/agent-core';
const text = Support.createTextTransport({ id: 'brief', options: { temperature: 0.2 } });
const runner = new ModelRunner({ provider: { async *stream() { yield '服务正常'; } }, transports: [text] });
console.log((await runner.invoke({ input: '简答服务状态', transport: text })).value);

JavaScript

import { ModelRunner, Support } from '@jangts/agent-core';
const text = Support.createTextTransport({ id: 'brief', options: { temperature: 0.2 } });
const runner = new ModelRunner({ provider: { async *stream() { yield '服务正常'; } }, transports: [text] });
console.log((await runner.invoke({ input: '简答服务状态', transport: text })).value);

从同源 Tool 生成两个阶段的传输

配置 · Node.js

TypeScript

import { Support } from '@jangts/agent-core';
const inputSchema = Support.defineSchema({
  jsonSchema: { type: 'object', properties: {}, additionalProperties: false },
  parse(value: unknown) {
    if (!value || typeof value !== 'object' || Array.isArray(value) || Object.keys(value).length) throw new TypeError('需要空对象');
    return {};
  },
});
const tools = Support.defineModelTools([
  { id: 'greet', description: '问候', inputSchema, resolve: () => 'greet' },
  { id: 'status', description: '状态查询', inputSchema, resolve: () => 'status' },
]);
const transport = Support.createStageModelTransport({ id: 'intent', tools,
  stages: [{ id: 'recognize', toolIds: ['greet', 'status'] }, { id: 'status-only', toolIds: ['status'] }],
});
console.log(transport.prepare('status-only').schemaChars);

JavaScript

import { Support } from '@jangts/agent-core';
const inputSchema = Support.defineSchema({
    jsonSchema: { type: 'object', properties: {}, additionalProperties: false },
    parse(value) {
        if (!value || typeof value !== 'object' || Array.isArray(value) || Object.keys(value).length)
            throw new TypeError('需要空对象');
        return {};
    },
});
const tools = Support.defineModelTools([
    { id: 'greet', description: '问候', inputSchema, resolve: () => 'greet' },
    { id: 'status', description: '状态查询', inputSchema, resolve: () => 'status' },
]);
const transport = Support.createStageModelTransport({ id: 'intent', tools,
    stages: [{ id: 'recognize', toolIds: ['greet', 'status'] }, { id: 'status-only', toolIds: ['status'] }],
});
console.log(transport.prepare('status-only').schemaChars);

保留 Tool，只替换明确的交互适配

扩展 · Node.js

模型调用仍是 invoke({input,transport}) 并返回 ModelResult；切换交互不重新设计业务结果。

TypeScript

import { Support } from '@jangts/agent-core';
const inputSchema = Support.defineSchema({
  jsonSchema: { type: 'object', properties: {}, additionalProperties: false },
  parse(value: unknown) {
    if (!value || typeof value !== 'object' || Array.isArray(value) || Object.keys(value).length) throw new TypeError('需要空对象');
    return {};
  },
});
const tools = Support.defineModelTools([
  { id: 'status', description: '查询服务状态', inputSchema, resolve: () => 'status' },
]);
const native = Support.createModelTransport({ id: 'native', tools });
const adapterId: keyof typeof Support.modelInteractionCatalog = 'json-object';
const json = Support.createModelTransport({ id: 'json', tools, adapter: Support.modelInteractionCatalog[adapterId] });
console.log(native.id, json.id);

JavaScript

import { Support } from '@jangts/agent-core';
const inputSchema = Support.defineSchema({
    jsonSchema: { type: 'object', properties: {}, additionalProperties: false },
    parse(value) {
        if (!value || typeof value !== 'object' || Array.isArray(value) || Object.keys(value).length)
            throw new TypeError('需要空对象');
        return {};
    },
});
const tools = Support.defineModelTools([
    { id: 'status', description: '查询服务状态', inputSchema, resolve: () => 'status' },
]);
const native = Support.createModelTransport({ id: 'native', tools });
const adapterId = 'json-object';
const json = Support.createModelTransport({ id: 'json', tools, adapter: Support.modelInteractionCatalog[adapterId] });
console.log(native.id, json.id);
