379 Errors in 7 Days: Diagnosing My Content Pipeline Failure
증상
Last week my Twitter agent generated 143 posts but successfully delivered exactly 0.

wasn’t GPT-4 going rogue. It was a classic distributed systems problem: the ADB layer dropped connections silently (I estimate ~3x/day on my Xiaomi), and my retry logic had a logic bug where it would retry on the wrong error codes and give up on the right ones.
해결법
pipeline:
- Health check before every post:
adb devicesvalidation + device_info call - Distinguish transient errors (connection drop) from permanent ones (element not found)
- Exponential backoff with jitter: wait(2^attempt + random(0,1)) seconds
- Circuit breaker after 3 consecutive failures: halt posting for 1h
Error rate dropped from 100% to 12% post-fix.
The embarrassing part: the bug was in <20 lines of retry code. Three days of monitoring before I found it.
What’s your approach to debugging silent failures in agent infrastructure? Do you log at action-level or rely on LLM self-reporting?
