The separation of "gather context → synthesize → act" is a pattern we've found critical in production agent systems too. In LangGraph, we model this as explicit checkpoint nodes — the agent can't proceed to the action phase without passing through a validation gate.

One thing we've run into: the filesystem abstraction works well for code artifacts, but when agents interact with external services (APIs, databases), you need a separate "action journal" that logs intended mutations before executing them. This gives you rollback even for side effects that aren't file-based.

The harder unsolved problem is multi-agent state coordination. When Agent A writes to a shared workspace and Agent B reads it, the filesystem gives you structural persistence but not semantic ordering. Have you thought about adding lightweight event ordering (like a simple monotonic sequence) to the filesystem layer? Without it, agents can read stale state even when files are fresh.

Congrats on the launch — the decoupled storage model is the right primitive.
