Protect your disk from pressure spikes with Storage Ballast Helper.
SBH (Storage Ballast Helper) is a cross-platform disk-pressure defense tool designed for AI coding workloads. It pre-allocates a “ballast” file that can be released when disk space runs critically low, buying time to clean up.
Agent coding sessions generate enormous amounts of build artifacts, logs, and caches. SBH monitors disk usage and automatically releases ballast when pressure exceeds configurable thresholds.
