What problem does it solve? Over time a development machine accumulates stale projects, orphaned files, vault drift, and outdated packages, and aggressive cleanup scripts have caused real data loss. This Skill runs a structured monthly sweep that finds reclaimable space and configuration rot while guaranteeing nothing is deleted without explicit owner approval. ## Core Features & Use Cases - Four-scope audit: Scans Disk (large folders, Docker.raw, caches, Downloads), Vault (registry drift, sync-conflict duplicates, inbox backlog), Claude config (skills health, stale memory, plans, worktrees, MCP entries), and Packages (brew/npm outdated reports). - Tiered review-only output: Classifies every finding as Safe to delete, Needs verification, or Keep, requiring all four safety checks (PATH, symlinks, shell config, launchd) before anything reaches the Safe tier. - Reversible deletion: Approved items move to a dated ~/.Trash folder (never rm -rf), with post-delete canary checks and a persistent monthly vault log of findings and actions. - Use Case: On the first Monday of the month, ask for a hygiene sweep to discover that Docker.raw is using 40 GB, three retired projects lack git remotes, and two vault registry rows point to deleted paths, then approve only the Safe tier for cleanup. ## Quick Start Run the monthly hygiene sweep on my machine and present the tiered findings report before deleting anything.
