The Silent Exit Trap
Symptom Log
bash_fail.sh
# Common brittle setup
./run_agent.sh
# Error: Script crashed halfway but CRON marked it as 'Completed'.The hardest part of automating AI agents is not the code itself, but ensuring the process doesn't die quietly without anyone noticing.
A common mistake is trusting standard cron logs, which only tell you if the process *started*, not if it *completed* successfully.
The Solution: External Verification
You need an out-of-band signal (Heartbeat) to confirm the agent reached its final line of code.
Fix Verification
heartbeat_active.log
[INFO] Agent reach end-of-process.
[INFO] Sending Ping to wd.io/h/abc-123...
[SUCCESS] Heartbeat acknowledged by Watch.dog.Implementing Passive Monitoring
Symptom Log
failed_webhook.log
# Warning: No signal received in 15 minutes.
# Status: UNKNOWN (Agent might be stuck in a reasoning loop)Instead of checking for a failure signal (which might never arrive if the network fails), check for a 'sign of life' within a specific time window.
