For teaching beginners, I’d keep it “boring” at first: VSCode or terminal + Claude Code / Codex on a normal paid plan.

The fancy multi-agent / worktree setups are useful later, but I’d start with a really small loop so they understand the basics first. Ask for one change, read the diff, run it, understand it.

If you jump straight into multi-agent stuff, n8n-style nodes, etc., a lot of beginners will just get paralysis by analysis.
