Definition

interface RegistrationDefinition<Context>

Type parameters

Type parameter	Constraint	Default type
Context	—	—

Field structure

Field	Type	Required	Description
id	string	Required	Read-only. Unique step id; also the catalog key.
when	((context: Context) => boolean) | undefined	Optional	Read-only. Installs the step when true; must be synchronous and is re-evaluated per install.
register	(context: Context) => void	Required	Read-only. Performs the installation; must return void synchronously.

Member index

Member	Purpose
register	Performs the installation; must return void synchronously.

Member details

register

Performs the installation; must return void synchronously.

RegistrationDefinition.register(context: Context): void

Parameter	Type	Passing	Description
context	Context	Required	—

Returns: void.

Examples

• Tool module composition and declarative installation: List modules, tool references, and registration order in one place; the generic loop consumes only that actual list.

Reuse existing module declarations directly

Beginner · Node.js

TypeScript

import { Support } from '@jangts/agent-core';
const modules = [{ id: 'service', description: '服务查询能力', tools: [{ id: 'get_status' }] }];
const catalog = Support.defineCapabilityCatalog(modules);
console.log(catalog.ids(), catalog.findToolOwner('get_status')?.id);

JavaScript

import { Support } from '@jangts/agent-core';
const modules = [{ id: 'service', description: '服务查询能力', tools: [{ id: 'get_status' }] }];
const catalog = Support.defineCapabilityCatalog(modules);
console.log(catalog.ids(), catalog.findToolOwner('get_status')?.id);

Add tool references and ordered installation

Configuration · Node.js

TypeScript

import { Support } from '@jangts/agent-core';
const modules = [{ id: 'service', description: '服务查询', tools: [{ id: 'get_status' }],
  references: [{ id: 'status-skill', requiredToolIds: ['get_status'], optionalToolIds: [] }] }];
const moduleCatalog = Support.defineCapabilityCatalog(modules, { toolReferences: module => module.references });
const registration = Support.defineRegistrationCatalog<{ installed: string[] }>([
  { id: 'service', register: app => { app.installed.push(moduleCatalog.require('service').id); } },
  { id: 'status-view', when: app => app.installed.includes('service'), register: app => { app.installed.push('status-view'); } },
]);
const app = { installed: [] as string[] };
registration.install(app);
console.log(app.installed);

const moduleCatalog = Support.defineCapabilityCatalog(modules, { toolReferences: module => module.references });
const registration = Support.defineRegistrationCatalog([

const app = { installed: [] };
registration.install(app);
console.log(app.installed);
