Python utility uses atomic mkdir to bring mutex locking to multi-agent AI workflows

A developer has released lock_folder_util.py, a zero-dependency Python script designed to prevent race conditions when multiple AI agents share a single resource simultaneously. The tool exploits the filesystem's atomic mkdir operation — which either succeeds or fails cleanly — as a mutual-exclusion lock, requiring no external libraries beyond Python 3's standard library. Every lock acquisition, release, and timeout is logged with a UTC timestamp and a per-agent identifier, giving teams a full audit trail of resource access. A built-in stale-lock mechanism automatically detects and breaks locks left behind by crashed agents after a configurable timeout, defaulting to 600 seconds. The utility is compatible with macOS, Linux, WSL, and BSD systems, and can be pointed at a custom lock directory via an environment variable.
