First, summarize what it does, its dependencies, license status if identifiable, and any risks. Show the exact files you propose to add under .agents/skills/cis-aws-compute-10-4/. Do not write files or run scripts until I approve.

After I approve, install the complete skill folder, including required referenced files, into that project location. Verify it is discoverable, then tell me its actual invocation name and how to use it. Do not claim it is installed until you have verified it.

10.4 Ensure that HTTPS is enabled on load balancer (Manual)

Description

The simplest way to use HTTPS with an Elastic Beanstalk environment is to assign a server certificate to your environment's load balancer.

Rationale

When you configure your load balancer to terminate HTTPS, the connection between the client and the load balancer is secure.
