# LayerFS: The filesystem for AI coding agents > Source: > Published: 2026-10-21 12:34:46+00:00 Compute exists only while a command runs. - **Compute:** Agents spend ~80% thinking, ~10% in Bash. - **FS:** Each file tool call is one atomic Store op. - **Sandbox:** Each Bash tool call mounts an ephemeral workspace, then commits. Agents on different computers share one serverless Store. - **Shared storage:** Every agent commits to one Store, with no DB server. - **Distributed computing:** Each agent runs on its own computer. One project, many branches. One branch, many agents. - **Commits:** Every tool call is a commit on its branch. - **Conflict:** A same-file clash is refused with Conflict. - **Blame:** Each line names the step that wrote it. Fork recursively any commit, at any depth. - **Zero cost:** A fork is metadata and copies no files. - **Recursive:** A filesystem for RSI agents and recursive exploration for RL training. 10 copies compress into 0.31. - **Dedup:** Each content chunk is stored once. - **Compression:** The stored chunks shrink further. - **Ratio:** 10 copies → 1.05 dedup → 0.31 compression wtf??? Dependencies come with every mount. No wasting time for re-installation. - **Git / other AgentFS:** Drops ignored files; reinstalls. - **LayerFS:** Ignored files stay in every commit. - **Comparison:** ~5 min to install vs 0.05 s to mount.
