An Agent Can Move and Still Not Be Portable

Summary

Moving an agent’s saved state to another system does not necessarily preserve its ability to use external tools. This workshop paper tests that distinction by resuming identical saved state with the original tool source available or absent. Experiments with LangGraph and PermeantOS examine dependencies on references returned by tools and on the authority to keep using them, arguing that claims of portability need to account for what remains tied to the original source.
