How it works
xcode-disk-cleanup
When your agent uses it
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, or install failing with an out-of-disk-space error. Always measure first, report recoverable GiB with evidence, and obtain explicit itemized approval before any mutation.

# 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outdated documentation caches”) as approval of the matching, current frozen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.
