feat(backend,testing): Add agent tasks endpoints & helpers

[tmilewski]

Description

Adds support for the Agent Tasks API endpoint to the backend SDK. This allows developers to create agent tasks that can be used to act on behalf of users during testing or other automated flows.

Usage

import { createBackendApiClient } from '@clerk/backend';

const client = createBackendApiClient({ secretKey: 'sk_test_...' });

// Create an agent task
const agentTask = await client.agentTasks.create({
  onBehalfOf: {
    userId: 'user_xxx',
  },
  permissions: '*',
  redirectUrl: '...',
});

console.log(agentTask.url);

import { createAgentTestingTask } from '@clerk/testing/playwright';
import { expect, test } from './base';

test.describe('Logged In State', () => {
  test('should display logged in message', async ({ page }) => {
    const userId = process.env.CLERK_TEST_USER_ID!;

    const { url } = await createAgentTestingTask({
      // secretKey: process.env.CLERK_SECRET_KEY!, // Optional, inferred otherwise
      onBehalfOf: {
        userId,
      },
      permissions: '*',
      agentName: 'test-agent',
      taskDescription: 'test-task',
      redirectUrl: 'http://localhost:3000/authenticated'
    });

    await page.goto(url);
    await expect(page.locator('header')).toContainText(`User is logged in ${userId}`);
  });
});

// Testing with custom client

const client = createClerkClient({
  apiUrl: 'https://...';,
  secretKey: process.env.CLERK_SECRET_KEY!,
});

const { url } = await createAgentTestingTask({
  clerkClient: client,
  onBehalfOf: {
    userId: process.env.CLERK_TEST_USER_ID!,
  },
  permissions: '*',
  agentName: 'test-agent',
  taskDescription: 'test-task',
  redirectUrl: 'http://localhost:3000/authenticated'
});

📝 Walkthrough

Walkthrough

Adds Agent Tasks support across the backend and testing packages. Introduces a new AgentTaskAPI with create and revoke methods and registers it on the backend API client as agentTasks. Adds an AgentTask resource model, AgentTaskJSON type, and deserialization for ObjectType.AgentTask. Exposes the endpoint via endpoints index and top-level backend exports. Adds tests for request/response mapping. Testing packages gain a createAgentTestingTask helper with Playwright and Cypress adapters and accompanying changesets.
