Filesystems as the new primitive for AI agents: three hard problems
pilver7 · reddit · 2026-09-25
After arguing that filesystems are a natural interface for AI agents (models already know ls, cat, grep), the author distills three problems raised by the community:
- Overwrites: two agents editing the same file can silently clobber each other's work; shared access needs conflict detection and reconciliation.
- Token-hungry retrieval: navigating thousands of files via listing and search can fill context without answering the question; indexes or targeted retrieval help.
- Reviewable, recoverable mistakes: an agent's bad edit can be built upon by others; history is needed to inspect, trace, and restore.
Git works for single-agent review, but multi-agent concurrent edits at high velocity need more. The author is building AgentWS, a persistent agent filesystem/workspace with a control plane for ingesting app data, access control, change coordination, and cross-run persistence, at agentws.dev.
