Audit and safely clean Xcode-related developer storage on macOS. Use whenever a developer mentions low disk space, Xcode storage, DerivedData, simulator devices or runtimes, stale beta platforms in Xcode Settings, DeviceSupport, archives, dSYMs, CocoaPods caches, simulator dyld caches, project .build folders, downloaded Xcode DMGs/XIPs, duplicate Xcode installers, or old Xcode applications. Also use this skill proactively when you hit low storage during other work, such as a build, download…
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
# Xcode Disk Cleanup ## Safety contract - Treat every cleanup request as permission to audit, not permission to delete. - Never mutate storage before presenting exact candidate IDs, paths or simulator identifiers, measured sizes, risks, and regeneration costs. - Treat a category-level request made after an audit (for example, “remove all outdated documentation caches”) as approval of the matching, current frozen selection set when it was already fully enumerated to the user. Execute in that turn after revalidation; do not restate the set and ask again. No special command or repeated confirmation is required. Broad requests made before an audit, such as “clean Xcode” or “delete everything,” remain audit-only. - Default ordinary files and directories to Trash. Explain that space is not reclaimed until Trash is emptied, and request separate approval before doing so. - Revalidate identity and running-process usage immediately before mutation. - Never use wildcards, unbounded `rm -rf`, `sudo`, SIP changes, or manual deletion inside system-managed CoreSimulator and MobileAsset directories. - Preserve archives and dSYMs unless the user proves the exact distributed build …

How to install
mdr add patrickserrano/lacquer/xcode-disk-cleanup@sha256:b070fa1eb8513db2The line at the top of this page pins the label git:20260828.954f5e3, 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.
