Five ways his unsupervised agents actually failed at night
A Portuguese-language operator who runs a small automation business (automatic posts, digital product distribution, nightly Python and the AI jobs) catalogs failures that really happened in his operation: a post sent twice because a timeout made the agent eagerly retry a send that had already landed; whole nights of jobs silently lost when a Windows update rebooted his PC and nothing raised an error; a job that only breaks under the 3 a.m. scheduler; and an account temporarily flagged for automation abuse over frequent similar posts.
How it works
- Operation runs scheduled posts, product distribution and nightly jobs
- A request times out after succeeding, the agent retries, and the post goes out twice
- A Windows update reboots the PC overnight and that night's jobs never run, with no error anywhere
- A job that works by hand fails only under the scheduler's environment
- Similar posts at short intervals get the account flagged for automation abuse until a review lifts it
Why it’s worth knowing
His core lesson inverts the usual advice: the failures were not bad prompts but missing brakes, so he moved every guardrail out of the prompt and into the code.
