public class CapabilitiesList extends BaseCommand
Command-line interface for listing all service capabilities in the Wanaku system.

This command provides functionality to discover and display both management tools and resource providers available in the system, along with their current status and activity information. It combines data from multiple API endpoints to present a unified view of system capabilities in a tabular format.

The command supports the following functionality:

  • Fetches management tools and resource providers from the API
  • Retrieves activity status for each service
  • Merges and correlates data from multiple sources
  • Displays results in a formatted table with columns for service, type, host, port, status, and last seen

Usage examples:

 # List all capabilities using default host
 wanaku capabilities list

 # List capabilities from a specific host
 wanaku capabilities list --host http://api.example.com:8080

Output format:

 service | serviceType       | host          | port | status | lastSeen
