+"""Sample agent using Vertex AI Agent Engine Sandbox for computer use.
+
+This sample demonstrates how to use the AgentEngineSandboxComputer with ADK
+to create a computer use agent that operates in a remote sandbox environment.
+
+Prerequisites:
+  1. A GCP project with Agent Engine setup (https://docs.cloud.google.com/agent-builder/agent-engine/set-up)
+  2. A service account with roles/iam.serviceAccountTokenCreator permission
+  3. Environment variables in contributing/samples/.env:
+     - GOOGLE_CLOUD_PROJECT: Your GCP project ID
+     - VMAAS_SERVICE_ACCOUNT: Your service account email
+     - VMAAS_SANDBOX_NAME: (Optional) Existing sandbox resource name for BYOS mode
+     - VMAAS_SANDBOX_TEMPLATE_NAME: (Optional) Sandbox template name to create a new sandbox (mutually exclusive with VMAAS_SANDBOX_NAME)
+     - VMAAS_SANDBOX_SNAPSHOT_NAME: (Optional) Sandbox snapshot name to create a new sandbox (mutually exclusive with VMAAS_SANDBOX_NAME)
+
+Usage:
+  # Run via ADK web UI
+  adk web contributing/samples/sandbox_computer_use
+
+  # Run via main.py
+  cd contributing/samples
+  python -m sandbox_computer_use.main

+1. Think about what steps are needed to accomplish it
+2. Take actions one at a time, observing the results
