disk-jockey SKILL.md skillA
disk-jockey from bmcreations/disk-jockey is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add bmcreations/disk-jockey/disk-jockey@git:20261023.80d0961Pins git:20261023.80d0961 in mdr.lock. Pin the fingerprint instead.

Diagnose and safely reclaim disk space on developer machines filled by AI agents, worktrees, builds, simulators, emulators and toolchain caches (Xcode, Android/Gradle, Node, Docker, Python, Rust, Go). Use when disk is low or filling fast, builds fail with "No space left on device", kernel_task shows huge disk writes, or the user asks to clean up storage.
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-jockey Spins down your simulators, drops your stale tracks, keeps the dance floor clear. Agentic workflows fill disks in new ways: one git worktree per task, each with a full build; parallel test runs cloning simulators; daemons and simulators left running until memory spills into swap. This skill finds the real cause first, then deletes only what is provably safe. All scripts are in `scripts/`, read-only by default, and need only bash 3.2+ (stock macOS) and standard tools. ## Safety contract - **Never delete without a dry run shown to the user first.** Every script defaults to a dry run; `--apply` acts. - **Get confirmation before `--apply`**, unless the user explicitly said to go ahead for that tier. - **Tier 3 is never deleted by you.** Show the size and give the user the command. - **Never hand-roll `rm -rf`** for something the scripts don't cover. Add a line to `targets.conf` instead so it gets the guards: protected paths, symlink refusal, busy-process skip. - **Never `git worktree remove --force` or delete branches** unless the user names the worktree or branch and accepts losing its uncommitted changes. …

How to install
mdr add bmcreations/disk-jockey/disk-jockey@sha256:787d81deb77de089The line at the top of this page pins the label git:20261023.80d0961, 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.
