What Is an AI Agent Handoff? A Folder Isn't a Handoff
A handoff is the moment one AI agent passes work to another, and it needs two things to be real: a named receiver and a signal that the work is ready. Without both, the finished work sits somewhere neither agent is watching, and nobody is wrong about it.
Nothing errors. Nothing gets refused. It just stops.
The tray on the desk nobody owns
Think of an office with an in-tray sitting on a shared table. You finish something and put it in the tray. Somebody will pick it up.
Who? When? On a good week, immediately. On a normal week, the tray becomes a place things go to be forgotten, and the person who put something there thinks it's moving while the person who might collect it doesn't know it arrived.
The tray isn't the problem. The problem is that putting something in it isn't addressed to anybody.
In the agentic world it's a folder
Same shape. Your first agent finishes a draft and saves it to the shared folder. Your second agent is capable of taking it from there and would do it well.
Two days later it hasn't moved.
The first agent believes it handed the work over. It performed the action that means "handed over" in its own instructions. The second agent was never told anything, because a file appearing isn't a message. Both behaved correctly and the work is still sitting there.
This is the failure that survives longest, because there's nothing to find in a log. No error, no refusal, no retry. Only absence.
What a real handoff contains
Two things, and both of them are boring.
- A named receiver. Not "the team", not "the next step", not a folder. The agent that owns it next, by name. If nobody is named, nobody has it.
- A signal. Something that reaches the receiver rather than waiting to be noticed. A message, a trigger, a queue it actually watches.
Worth adding when the work matters:
- What "ready" means, so the receiver isn't guessing whether a draft is finished or abandoned.
- What to do if it can't proceed. An agent that can't act and can't escalate goes quiet, which looks exactly like success.
Why this gets skipped
Because with one agent it never comes up. One agent finishing something and then doing the next thing needs no handoff at all, and every habit you built with one agent silently assumed that.
The second agent is when the assumption breaks, and it breaks quietly.
The check
Take the last thing that went from one of your agents to another. Ask who was named, and what reached them.
If the answer to either is "the folder", you don't have a handoff. You have a tray.
What is an AI agent handoff?
The moment one agent passes work to another. To be real it needs a named receiver and a signal that reaches them, rather than a file appearing somewhere and waiting to be noticed.
Why does work get stuck between AI agents?
Because a shared folder is not addressed to anybody. The sending agent believes it handed over, the receiving agent was never told, and both behaved correctly.
Is a shared folder a handoff?
No. A file appearing is not a message. Without a named receiver and a signal, the work sits in a place neither agent is watching.
Why is this failure hard to spot?
Nothing errors, nothing is refused, nothing retries. There is no log entry for work that simply stopped, only absence.
What else belongs in a handoff?
A definition of ready, so the receiver is not guessing whether a draft is finished, and an escalation path for when it cannot proceed. An agent that goes quiet looks exactly like an agent that succeeded.
