In a single-agent system, failure is simple: the agent errors, you retry.
In multi-agent systems, failure is a graph problem.
The Cascade Failure Problem
Agent A: ✅ Success
Agent B: ❌ Timeout (depends on A)
Agent C: ❌ Skipped (depends on B)
Agent D: ❌ Partial data (depends on C)
One timeout propagates through the entire pipeline. Without recovery, your system is fragile.
Our Recovery Strategy
AgentForge implements 3 recovery layers:
Layer 1: Retry with Exponential Backoff
@retry(max_attempts=3, backoff=exponential(base=2, max=60))
def agent_call(params):
return llm.invoke(params)
Layer 2: Circuit Breaker
If an agent fails 5 times in 10 minutes, we stop calling it and return a degraded response:
{
"status": "degraded",
"agent": "market_data",
"fallback": "cached_data",
"warning": "Real-time data unavailable, using 15-min delayed feed"
}
Layer 3: Pipeline Re-planning
When a critical agent fails, the orchestrator can re-plan:
- Skip the failed step if non-critical
- Substitute with a backup agent
- Halt and alert with full context trace
A Real Incident
Last month, our market data API went down during trading hours. Here's what happened:
- 14:32 — Market data agent timeout (Layer 1: 3 retries failed)
- 14:33 — Circuit breaker opened for market data agent
- 14:33 — Pipeline automatically switched to cached data + warning flag
- 14:35 — Full report generated with "delayed data" disclaimer
- 15:00 — Market data API recovered, circuit breaker closed automatically
Zero manual intervention. Zero missed reports.
This Is Table Stakes
If your multi-agent system can't handle one agent failing, it's not production-ready.
AgentForge makes this the default, not an afterthought.
