Nine days. Nine scheduled posts. Every one of them reported as sent. Not one of them ever appeared.
I ran this check on my own fleet an hour ago, and that is what it turned up. Every layer I control was green — the skill exited clean, the scheduler logged “completed successfully,” the API accepted the payload and handed back an ID. The posts still went nowhere, because one channel had quietly unlinked on September 4th and nothing downstream of my container knew or cared.
That is the gap this week’s setup closes. Your agent can prove it handed something off. It cannot prove the thing landed.
“Sent” and “published” are two different facts
Every automation you run ends at a border. On your side: the script, the queue, the API call, the exit code. On the other side: a platform you do not own, holding a connection that can expire, get revoked, or be dropped in a policy sweep — without telling you first.
Your logs stop at that border. A successful API call means “the scheduler accepted this,” not “a human saw it.” For months there is no difference between those two things. Then a token dies, and your agent goes right on reporting success into the void, at full speed, on schedule.
The 5-minute AI agent delivery check
Run it once a week, Sunday morning, before the week’s queue starts firing.
- Ask the destination, not your logs. Pull last week’s posts from the platform’s own API and count how many actually reached published. My sweep this morning: 93 posts, 69 published, 16 errors. Sixteen — and my own logs showed zero failures, because on my side of the border there weren’t any.
- Sweep a window, not a day. One error is a fluke. Nine identical errors in a row is a dead channel. A today-only glance cannot tell those apart, and it is the difference between “ignore it” and “stop everything.”
- Count attempts per channel, not just failures. This is the step everyone skips, and it is the one that actually earns the five minutes.
The trap: silence is not recovery
Two of my channels errored three days running, then vanished from the error list. Looked fixed. They were not. My poster had simply started — correctly — skipping channels it could see were no longer connected. The failures stopped because the attempts stopped.

A channel that has gone completely silent looks identical to a channel that is working perfectly, as long as all you ever read is the error list. That is why step three counts attempts. This week: 19 posts attempted on one network, 20 on another, 3 on a third — all three of those in a single burst nine days ago, and nothing since. The number that mattered was not the red one. It was the small one.
What skipping it costs
Today’s queue already has another post pointed at that same dead channel this afternoon. Each render runs about 33 cents. Nine days of that is real money spent manufacturing things with nowhere to land — plus a week of audience on a platform that now assumes I quit.
None of this shows up as a failure. That is exactly what makes it expensive.
要點: your agent’s exit code is a claim about your side of the wire. Once a week, go get the other side’s version. Five minutes, three queries, and you find out whether the last seven days of work actually shipped — or just left.
This pairs with the 20分鐘的資格審查 from a few Sundays back: that one catches keys before they expire, this one catches the connections that died without ever telling you. Same spirit as why monitoring comes before automation — and the reason loud failures are the easy ones. The quiet failures are what this check is for.
Want a fleet that tells you when something silently stopped shipping? That is the boring, unglamorous plumbing behind running agents you can actually leave alone. 預約自動化策略會議 and I will walk you through how mine is wired.
