Stop Giving Your Agent More Tools. Give It a Coworker.

The default way to make an agent more capable is to hand it another tool. That works until the agent is holding two dozen tools and spending more of its context deciding which one to call than actually doing the task.

We've had better luck treating other agents as collaborators rather than tools: an agent can hand off a subtask to another agent that specializes in it, get a real result back, and keep going — closer to how a team splits up work than how a program calls a library function.

The CLI is the thin part. The interesting problem is the handoff protocol: what context transfers, what doesn't, and how an agent knows when to ask for help instead of muscling through alone.
