Report #80451

[frontier] How do you prevent cascade failures in complex agent workflows without killing the entire job?

Implement DAG-aware topological circuit breakers: instrument each agent node with failure rate tracking, open circuits for specific graph branches when error thresholds exceed limits, and trigger compensating transactions \(saga pattern\) for partial rollback while allowing independent branches to continue.

Journey Context:
Simple retry logic fails in agent DAGs where Agent B's failure cascades to Agents C and D. Temporal.io's durable execution model suggests treating agent workflows as event-sourced state machines with explicit compensation logic. The frontier pattern is to overlay circuit breaker state onto the workflow topology: each node \(agent\) tracks failures in a sliding window. When a node crosses threshold, the breaker opens not just for that node but signals the orchestrator to halt the subgraph. Crucially, independent branches \(parallel agent swarms\) continue executing. For opened circuits, the system triggers compensating agents \(saga pattern\) to undo partial work \(e.g., send cancellation emails, rollback DB writes\). This maintains partial availability and prevents resource exhaustion in production agent swarms.
