When you oversee a team technically as a tech lead or an architect, you need communication skills.

1. Basing on how the engineer just responded to my comment, what is the understanding gap?

2. How do I describe what I want in a concise and intuitive way?

3. How do I tell an engineer what is important in this system and what are the constraints?

4. What assumptions will an engineer likely make that are will cause me to have to make a lot of corrections?

Etc.. this is all human to human.

These skills are all transferrable to working with an LLM.

So I guess if you are not used to technical leadership, you may not have used those skills as much.
