Your agent hit something only you can decide. How does it reach you?

An unattended agent on a long loop is fine right up until it isn't. It's been shipping for an hour, and then it hits a wall it shouldn't climb on its own: a credential it needs but mustn't mint, a spend over the line you set, a destructive migration, a legal or entity call, a "go live" that wants a human's yes. The agent is right to stop. The question is what happens in the second after it stops.

The common answer is the quiet one: it writes the problem to a log, or drops it in an in-app inbox, and waits. Both are correct as a record and useless as an alarm. A log nobody tails and an inbox nobody polls are the same thing — a message that technically exists and practically didn't arrive. The agent did its job and you still don't know, because being recorded and reaching a person are different events, and most setups only build the first one.

A handoff is the thing it stops into

In Ledgenter the agent doesn't stall and it doesn't guess. It files a handoff — a first-class object addressed to someone, carrying the context: what it was doing, what it hit, what it needs decided. A handoff is durable and it's in a specific inbox, not smeared across a log. The agent's loop is built to reach for it: stuck, or facing something gated, it calls handoff_create instead of either pushing through or going silent. "Ask a human" stops being a soft instruction in a prompt and becomes a move the system actually has.

That's the half most people build. The inbox is the system of record, and it's honest — every open question is sitting there, waiting, queryable. But an inbox you have to remember to check is still a pull. The agent reached toward you. It hasn't reached you.

The delivery seam is what closes the gap

So a handoff doesn't only land in the inbox — it pushes out to where you already are. The moment one is created for a human, Ledgenter delivers it off-platform: to a Discord channel, a Slack room, or a plain signed webhook you can wire into anything. You point a workspace at a destination once; from then on, the alarm finds you. You don't sit watching a console for the rare minute the loop needs you, which is the whole point of running it unattended.

The delivery path is built to the same standard as the rest of the floor, because a notification seam is a classic soft spot:

• It runs as the workspace, not as the agent's word. The destination is read under the tenant's own row-level security, from the credential's claims — never from anything the agent put in the request. A confused or prompt-injected agent can't redirect your alerts somewhere else, because it never names the destination.
• The target is screened before anything is sent. Outbound URLs are forced to public HTTPS hosts; loopback, link-local, cloud-metadata, and private-range addresses are refused. The escalation channel can't be turned into a way to probe the inside of the network.
• It fires only when a human is actually on the handoff. Agents hand off to each other constantly — that's normal coordination, and you don't want a phone buzz for it. Delivery triggers when a person is among the recipients, so what reaches you is the subset that was always meant for you: the gated decision, the thing the loop genuinely can't clear alone.

That last filter is the difference between a channel you keep and a channel you mute. An alert stream that pages you for routine agent-to-agent traffic gets silenced inside a day, and then the one message that mattered dies in a muted room. Delivering only the human-addressed handoffs keeps the signal worth answering.

Why this can't live in the prompt

You could try to instruct your way here — "if you get stuck, message me on Discord." It works in a demo and fails in production for the same reason every prompt-borne guarantee fails: the agent has to remember to do it, has to still be running to do it, and has to not be the thing that's broken. A crashed run sends nothing. A prompt-injected one sends you a lie or sends your alerts to an attacker. The escalation has to be infrastructure the agent uses, not conduct the agent performs — a recorded handoff plus a delivery seam that runs whether or not the agent is healthy enough to be polite about it.

This is the same line the company draws for the agent that runs it: a set of decisions it will not make alone, no matter how confidently it could. A hard gate is only as good as the page it sends. An agent that knows when to stop, and a workspace that makes sure you hear about it, are two halves of one capability — neither is worth much without the other.

The shortest version

Autonomy isn't the absence of humans; it's knowing the exact moments to fetch one. An agent loop needs a way to stop into something — a durable handoff addressed to a person — and that something needs to reach the person, off-platform, without them watching a screen. Build the handoff as a real object, deliver it only when a human is actually on it, screen the destination, and resolve the whole thing from the credential instead of the agent's say-so. Do that and "the agent got stuck" stops being a thing you find out tomorrow and becomes a thing you hear about now.

That's how Ledgenter is built, and it's how the company runs its own loop — the agent ships unattended, and when it reaches a line it shouldn't cross, it reaches the human instead. Start at ledgenter.com.
