DEFRAG for developer machines.

• Git worktrees: size, branch, last used, uncommitted files, commits nothing else has, and dev servers running inside.
• Stale worktree entries whose folders are already gone.
• node_modules across every project.
• Running dev processes: ports, memory, uptime, and the orphaned ones whose folder disappeared.
• Caches (npm, pnpm, Xcode, ~/Library/Caches, ~/.cache) for awareness.

• One-click Clean only for items that cannot lose work: clean worktrees (their branch is kept), stale entries, and reinstallable node_modules.
• Every item is re-checked right before it runs; anything that changed is skipped, never forced.
• Files go to the Trash on the same disk. Nothing is deleted or copied across disks.
• Processes are stopped only if the same pid still has the same start time.

Uncommitted files and commits that exist nowhere else need judgment. Reconcile builds one prompt per project with the live facts and the rules: rescue work onto a branch, follow the repo's AGENTS.md, never force, ask before discarding. Copy it into Claude or Codex in that folder.

A banner in the map, and opt-in desktop notifications from a background check every 6 hours: low disk, lots of safely reclaimable space, orphaned dev servers, piles of stale entries.
