# Genizah

> A free Claude Code plugin and Agent Skill that frees disk space on Mac, Windows and Linux safely. It measures first, asks before anything personal, sends personal files to the Trash instead of deleting them, and warns before anything important.

## Install

Claude Code plugin:
/plugin marketplace add Twistor-Labs/genizah
/plugin install genizah@genizah

Other agents that read Agent Skills:
npx skills add Twistor-Labs/genizah

claude.ai: download the skill zip from https://github.com/Twistor-Labs/genizah/releases/latest and upload it in claude.ai skill settings.

Without a plugin system: download the repository as a ZIP, unzip it, open the genizah folder in Claude Code.

Then say: "Help me free up space on my computer." Requires a paid Claude plan.

## How it works

- First run: explains itself and asks what it should never touch (a folder, an app, or a kind of file such as "all my videos"). The answer is saved in ~/.genizah/history.md (on Windows, %USERPROFILE%\.genizah\history.md).
- Sorts findings into three groups: Safe (caches, logs, temp files that rebuild themselves), Check with you (personal or unclear items, each with size and last-changed date), Do not touch (system files, the never-touch list, cloud and photo folders).
- Safe items are cleared after one yes. Personal items are shown one at a time, each needs its own yes, and each goes to the Trash or Recycle Bin.
- Important items (photos, documents, recent work, phone backups, emptying the Trash, anything over 5 GB that is not a cache) get a caution first: what would be lost, whether it can come back, and the backup status. Permanent actions need confirmation by item name.
- Checks whether a backup exists and says plainly if not.
- Never uses admin rights (sudo, Run as administrator) without asking first and saying why. Deletes by exact path, never by wildcard.
- Finishes with free space before and after, what was cleared, what waits in the Trash, and two or three tips.

## Never touched

Operating system files, snapshots and restore points; browser logins, passwords and history (only browser caches); cloud sync folders (iCloud Drive, OneDrive, Dropbox, Google Drive); photo libraries and chat app folders; virtual machine and container disk images; password manager, SSH and key folders; anything on the user's never-touch list.

## The name

For about a thousand years the Ben Ezra synagogue in Fustat, old Cairo, kept a storeroom called a genizah, where worn-out writings were set aside instead of destroyed, out of respect for texts that might carry the name of God. In 1896 scholars recognized around 400,000 pages there. Genizah the tool works the same way: set things aside first, erase last.

## Cost

Free, MIT licensed. Runs inside Claude, so it needs a paid Claude plan.
