My Mac was down to 26 GB free. The space wasn't in caches. It was in old projects, AI models, recordings, backups, and chat histories. So I wrote a skill that teaches AI agents to free it up without losing anything. Storage Rescue has two modes: 1. Offload. Big files go to an external drive and get checked by SHA-256 twice. Only then is the Mac copy deleted. Works with APFS, exFAT, FAT32, and NTFS. 2. Reclaim. No drive. Caches are cleared with each tool's own command, and your files go to the Trash first. The agent surveys the disk first, then asks you what to do with each group: move, delete, or keep. Nothing happens without a clear yes. On my Mac: 968 GB used before, 366 GB after. Free and open, plain text, no runtime. macOS only. Works with Claude Code, Codex, Cursor, Factory Droid, Devin, Hermes.
