Run agents with a CLI flag

What variant of Codex are you using?

CLI

What feature would you like to see?

Have an ability to run a preconfigured agent (using subagents pattern) explicitly with a CLI flag, like
codex --agent analyst or codex --agent developer.

Support in codex exec as well

Additional information

This is to have dedicated agent configurations together with the default instructions configured in the same root folder of the project.

We were using project-level profiles before the support for this was dropped in v 0.130

This is an equivalent of using claude --agent or GitHub Copilot agent selection drop down.
