Filesystems as the new primitive for AI agents: overwrites, token waste, and recoverability
pilver7 · reddit · 2026-09-25
- The author previously argued filesystems are a natural interface for AI agents (models already know ls/cat/grep); follow-up discussion surfaced three core problems:
- Concurrent overwrites: two agents edit the same file and the second save silently clobbers the first, often unnoticed by either.
- Token-hungry discovery: facing thousands of files, agents burn context on listing/searching/opening; indexes or targeted retrieval tools are needed.
- Reviewable, recoverable mistakes: a bad edit gets built upon by other agents; history is required to trace and restore.
- Existing tools like Git support single-agent flows, but multi-agent concurrency outpaces manual review. The author is building AgentWS (agentws.dev): a persistent filesystem/workspace with a control plane for data ingestion, access control, change coordination, and cross-run persistence.
