Opus 5.5 found 124 GB of developer leftovers on a Mac

Vox@Voxyz_ai

My Mac was down to 27 GB, so I had Opus 5.5 scan it read-only: 𝟭𝟮𝟰 𝗚𝗕 𝗼𝗳 𝗱𝗲𝘃𝗲𝗹𝗼𝗽𝗲𝗿 𝗹𝗲𝗳𝘁𝗼𝘃𝗲𝗿𝘀, and ~/.codex alone was 𝟱𝟵 𝗚𝗕, 31 GB of it old chats.

It drew the map below, and once you tick items it writes the cleanup script. 22.5 GB of it is caches and build output that gets re-downloaded or rebuilt when you need it.

Send this to Claude Code and see how much is on yours 👇
"Scan my home folder read-only. Look at sizes only and don't open any file contents. Skip iCloud, the Photos library and external drives, and skip any folder that triggers a system permission prompt. Find the big folders left behind by development work and build a local HTML page: a treemap sized by space, split into 'safe to remove' and 'let me review first'. Sessions, models and Docker always go under 'let me review first'. For each item, show the path, the size and what happens if it's deleted. When I tick items, generate a cleanup script that uses each tool's own clean command, and don't delete anything yourself. Append each item's size to ~/disk-report/sizes.csv, and next time read it first and flag what grew."
