Use when df says disk is above 80% full or the user wants to reclaim storage space on a VM.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Disk Cleanup Reclaim disk space on a Linux VM. The skill runs a **triage** — survey every space consumer, split targets into *safe* vs *ask*, execute the approved set, then verify the delta. ## When to Use - User says "disk cleanup", "free up space", "clean up the VM" - Disk usage above 80% - After large builds, git operations, or Docker image accumulation ## Procedure ### 1. Baseline ```bash df -h ``` **Done:** used and available numbers recorded for all mounts for the before/after comparison. ### 2. Survey **Requires root** for apt, journalctl, and /var/log operations. Non-root users can survey but cannot clean system paths. Build a ranked list of every consumer over ~50M. Survey all mounts, not just `/`. ```bash # All mounts (not just /) df -h df -i # inode exhaustion — "No space left on device" with free blocks # Deleted-but-open files (canonical "df says full, du says empty" case) lsof +L1 2>/dev/null | head -20 # Hermes data + user caches + tmp (stay on one filesystem, don't cross mounts) du -xsh ~/.hermes/*/ 2>/dev/null | sort -rh | head -20 du -xsh ~/.hermes/projects/*/ 2>/dev/null | sort -rh | head -20 …

How to install
mdr add moonlight-lupin/agent-skills/disk-cleanup@sha256:ff33abc6c88e78c8The line at the top of this page pins the label v1.3.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
