Diagnose and fix Linux disk full / no space issues. Find large files, clean logs, purge package caches, remove old kernels, handle Docker disk bloat, and expand filesystems. Use when df -h shows space critically low, applications fail with "no space left on device", or docker builds fail with ENOSPC.
This listing is from the official public ClawHub registry. Review SKILL.md and referenced scripts before running.
