The author noticed his local Cowork sandbox kept growing and that Archive doesn't actually delete files. His first attempt — letting Claude clean up the 23GB sandbox directly — broke Cowork, and he had to restore it with Codex and Claude CLI. After that he emailed Anthropic support and got the real session-folder path (~/Library/Application Support/Claude/local-agent-mode-sessions/<account>/<org>/ on Mac). Since he runs Windows, he had Claude CLI find the equivalent path, then list every session numbered by title so he could delete selectively. He packaged the whole flow as a /delete-old-cowork skill: cross-platform discovery, metadata-only reads (never transcripts), user-confirmed batch deletion, explicit refusal to touch agent/ or cowork-gb-cache.json — a safe scalpel for anyone hitting the same problem
