SafeHandoff: Verifiable Multi-Agent Coordination with Formal Guarantees
Framework for multi-agent systems ensures 99.7% handoff success through critic-verified protocols and sandboxed execution.
Anthropic’s SafeHandoff brings sanity to agent swarms. When Agent A hands to Agent B, 1-in-5 drops context or deadlocks. This paper’s critic layer pre-validates every transition with formal specs, catching disasters before they cascade.
What changed. Handoffs go from probabilistic dice-roll to 99.7% deterministic via TLA+ contracts that even non-formalists can read.
Why it matters. EY’s 130K auditors need this yesterday for their Azure agent rollout—multi-agent without coordination is just expensive chaos.
Builder takeaway. The framework’s LangChain integration ships with 5 battle-tested protocols; plug in Claude and ship swarm-ready agents. Read the paper.
