Cascading Failure

A concept in reliability engineering referring to the phenomenon in which the failure of one component in a system triggers a chain of failures in downstream components. In the context of AI Agents, it specifically denotes the progressive amplification of errors across multi-step pipelines, where a mistake in an earlier step propagates and magnifies through subsequent steps, ultimately causing the entire task to fail.

In multi-agent systems, one agent's retry may trigger unnecessary retries in downstream agents, creating cascading failures or thundering-herd problems.

Agents chain multiple steps together, with the output of each step becoming the input of the next, and errors are amplified along the chain; this is referred to in reliability engineering as cascading failure.

Cascading failure is a failure mode in distributed systems where a component failure causes request redirection that surges the load on other nodes, triggering an avalanche effect.
