Why Most Multi-Agent Systems Fail Even When Evaluation Passes

TL;DR

Multi-agent systems often appear to function correctly during evaluations but fail in real-world applications. This article discusses the watchdog pattern in Python to identify these hidden failures.

Key Takeaways

• Implement checks between agent nodes to validate data handoffs.
• Focus on the last internal handoff before external actions occur.
• Use lightweight models for quick validation without significant latency.
• Iterate on the placement of checks based on the cost of errors.
