disk-cleanup

To clean up Rust build artifacts across multiple git worktrees, run a disk-cleanup workflow that inventories all worktrees and executes cargo clean per worktree to safely reclaim disk space.

The safest way to prune merged git branches in a worktree setup is using a cleanup workflow with strict safety checks. It only removes branches merged to origin/main while protecting unmerged work and active worktrees.

Disk cleanup does not require Docker to be running because Docker system prune is entirely opt-in. The workflow relies on cargo, git, docker, and bc, but skips Docker pruning safely without explicit confirmation.

To shrink the WSL VHDX file after disk cleanup, the workflow prints exact PowerShell commands to run outside WSL. You execute these commands manually to compact the backing virtual hard disk and reclaim physical space.

If you run the cleanup workflow without any flags, it defaults to a dry-run mode that previews cleanup actions. No destructive steps execute until you re-run the command with the --apply flag.

You should not use automated disk cleanup when you have uncommitted changes or unmerged branches, as strict safety checks guard active worktrees. Always preview via dry-run first to ensure no important data is targeted.
