Automatic Error Recovery in AI Agent Networks

#ai #reliability #systems

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.
