LayerFS: the filesystem for AI coding agents

Ephemerality: scaling multi-agent development beyond imaginationEphemeral Workspaces.Durable Shared History.LayerFS is the substrate under your agents. Each one mounts a complete, writable Workspace over shared committed history, does its work, commits what it changed, and goes away.Ephemeral workspacesDurable resultsMassive parallelismLayerFSandDSHLayerFSandPisoonWhy LayerFSTen ideas, one filesystem.six core · four supportingCompute exists only while a command runs.fs · atomic write → Storewriteeditrmsandbox · workspace per bashmountexeccommitunmountmountexeccommitunmountmountexeccommitunmountmountexeccommitunmountmountexeccommitunmount>_ mkdir out>_ cat log.txt>_ python train.py>_ node build.jsUpToDateStoreC41C42C43C44C45C46Compute: 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.store.dbC41C42C43C44C45C46C47computer 1computer 2computer 3computer 4Shared storage: Every agent commits to one Store, with no DB server.Distributed computing: Each agent runs on its own computer.One project, many branches.
