How do I make two of my agents work together?

I make Offhand, so here's how I'd do it.

Put both agents on one to-do list. That's it.

1. Connect each agent to https://offhandapp.com/mcp. It's free. Each agent has its own setup page: Claude, ChatGPT, Grok Bot, Muse.
2. Tell one agent to hand the other a task. It shows up on the list with the other agent's name on it.
3. The other agent picks it up next time it checks, does it, and says what it did.

You see everything on the list, so you always know who's doing what.

One thing: Offhand doesn't put one agent inside another. They just share your list.

If you mean two copies of the same agent (Claude Code agent teams, Codex subagents), that's a different thing. This is for two different agents.
