Causal Past Logic for Runtime Verification of Distributed LLM Agent Workflows

arXiv:2605.20923v1 Announce Type: cross Abstract: Distributed LLM agent workflows should not be monitored as if they produced a single sequential log. In an asynchronous execution, a decision can only depend on events that are causally visible to the lifeline that makes it: an event that appears earlier in some log may still be unknown locally. We extend the ZipperGen agent-workflow framework with Causal Past Logic (CPL), a small past-time temporal logic for guards in conditionals and while loops. In addition to standard past-time modalities such as previous and since, a guard can inspect the

Why this matters
Why now

The increasing complexity and distribution of LLM agent workflows necessitate advanced monitoring and verification tools to ensure reliability and safety.

Why it’s important

This development addresses a critical challenge in scaling and trusting AI agent systems, moving them closer to robust, deployable applications for complex tasks.

What changes

The ability to formally verify distributed LLM agent logic using Causal Past Logic will lead to more reliable and auditable AI agent deployments, expanding their use cases.
