Recent discussions around agent infrastructure (like LangChain's framework vs runtime vs harness taxonomy) seem to miss a critical piece for truly autonomous systems. Most current setups, even sophisticated Agent Harnesses, still fundamentally rely on external triggers. They are reactive.
If the goal is a continuously operating, persistent agent that manages its own lifecycle, isn't an Agent Harness insufficient? We seem to need a specialized Agent Runtime Environment—and to be clear, I mean a persistent operational environment, not just an Execution Runtime Environment (like a sandboxed Docker container for running code).
A true Agent Runtime Environment would need to handle heartbeat mechanisms, self-healing, long-term memory consolidation, and proactive resource allocation without human intervention. Are any research groups or open-source projects actually building this persistent substrate, or are we still just building better ways to trigger scripts?
