ModelStageTransportRegistration

SUPPORT · interface · Type contract

Stage IDs and capability references are App-owned; this adapter only compiles their relation.

Import

TypeScript

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

JavaScript

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

Definition

interface ModelStageTransportRegistration<Result>

Extends or implements: ModelTransportRegistration<Result>.

Type parameters

Type parameter	Constraint	Default type
Result	—	unknown

Field structure

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

Examples

• Model transport and stage projection: Generate a sealed catalog and stage projections from tool definitions; native functions and JSON adapters share the same tool contract.

Create a named text transport

Beginner · 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);

Generate transports for two stages from same-source tools

Configuration · 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);
