Report #85665
[frontier] Cascading failures when agent handoffs trigger infinite loops or failing tool chains
Implement circuit breaker wrappers around handoff functions that trip after 3 failures or 5 loops, routing to a degraded-mode agent with cached heuristics
Journey Context:
Swarm has no built-in resilience. If Agent A calls Agent B, and B calls A due to logic errors, you hang indefinitely. Or if B's external API is down, you retry forever. Borrowing from distributed systems \(Nygard's patterns\), wrap handoffs in circuit breakers tracked in context\_variables. When failures exceed threshold, 'trip' the breaker and route to a fallback agent. This prevents one failing agent from killing the whole swarm latency budget.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
