Key Points

The article argues that AI agents will inevitably crash in production, and that simply using retry loops (e.g., try/except with fixed sleeps) is not sufficient for reliable service.
It explains why basic retries often fail: provider outages (e.g., HTTP 503) repeat the same failure, and when agents require multiple LLM calls per request, retries greatly increase latency without improving success.
It warns that rate-limit scenarios (HTTP 429) can be worsened by retry flooding, and that effective handling requires exponential backoff with jitter and rate-limit-aware strategies.
It proposes a multi-layer self-healing approach: exponential backoff retries for transient errors, model downgrade for overload, provider failover for outages, and learned/recurring recovery for predictable failure patterns.
