Skills only work if you have a full blown code execution environment with a model that can run ls and cat and execute scripts and suchlike.

The models are really good at driving those environments now which makes skills the right idea at the right time.

Why do you need code execution envs? Could the skill not just be a function over a business process, do a then b then c?

Turns out that basic shell commands are a really powerful for context management. And you get tools which run in shells for free.

But yes. Other agent platforms will adopt this pattern.

I prefer to provide CLIs to my agent

I find it powerful how it can leverage and self-discover the best way to use a CLI and its parameters to achieve its goals

It feels more powerful than providing pre-defined set functions as MCP that will have less flexibility as a CLI

I was fairly certain this was incorrect, but I decided to look it up before I responded. I'm glad I did. Simon is correct.

"Skills require the Code Execution Tool beta, which provides the secure environment they need to run."
