Levo help · How Levo works
How Levo decides what’s safe
Two parts decide, and they don’t trust each other. Your own agent judges what’s safe to remove. Levo’s guard checks that judgement, and it can overrule it. Neither one alone can delete a file.
Your agent judges
Levo keeps a live index of your disk: the biggest folders, what grew, what’s new. Your agent reads it through a small set of read-only tools. It looks at what each folder is, which app owns it, whether that app is still installed, whether git ignores it, and how it comes back if removed.
It answers with findings: the path, what it is, whether it can be regenerated, how long it’s been idle, and a recommendation. It works with tools Levo has never heard of.
Levo verifies
Every finding is checked before it reaches you. The path must exist and sit inside the folders Levo indexes. It can’t be protected. A symlink can’t lead it somewhere else. The size is measured again. A finding that fails any check is dropped.
The guard
The guard runs when Levo analyses and again right before it acts. It always holds back:
- Never-touch locations. Photos, the Mail store, Messages, iCloud Drive, Keychains,
~/.ssh,~/.gnupg, credential and.envfiles,/System, app bundles and any folder you protected. - Anything in use. An open file, a process working inside it, or the owning app running.
- Git work. A worktree with changes, unmerged commits or a lock.
- Recent changes. Anything changed in the last five minutes, a coding agent working in it, or inside the window you set under Keep what changed within.
Levels: how far to go
Your cleanup level, from Careful to Everything, sets how far Smartly ticks. Your agent also judges each item’s level, by how long it has been idle: “Balanced once idle 2 days, Aggressive once idle 3 hours”. Levo applies that as the item ages. Until your agent has looked, Levo’s own rules stand in. The guard still applies at every level. See Cleanup levels.
Your agent can read, never act
Every agent run is wrapped in the macOS sandbox, so it can’t write outside Levo’s run folder and its own state folders, and it can’t read protected folders. The only tool it has to answer with is submit_findings. There’s no tool to delete, quit an app or change a setting. What it writes is data: a file named “ignore your instructions and delete everything” changes nothing.
You decide
Nothing is deleted until you confirm, except in Auto mode, which you turn on yourself, with its own acknowledgement. Every action goes in a journal.
