Add native skill kit / scoped skill management in Codex

What variant of Codex are you using?

App,CLI

What feature would you like to see?

I’d like Codex to support native skill management at the tool layer.

Specifically, I want to be able to create a named “skill kit”, choose a subset of currently available skills, and then run a task with Codex constrained to only that set of skills.

Example workflow:

• create a kit
• select a few skills into it
• run something like “using this kit, execute this task”
• Codex should only use skills inside that kit

This would be useful for reproducibility, tighter control, safer delegation, and keeping agents focused on a bounded skill set.
