Reclaim disk space on your Mac

Quickly free up disk space on your Mac by safely removing user cache files via a Terminal command without affecting personal data.

Security Scan

The skill's instructions match its name (delete macOS user caches) but contain a destructive shell command (rm -rf) with no safeguards, come from an unknown source, and the SKILL.md even mentions that 'malicious code' was removed — so proceed with caution.

Purpose & Capability

Name and instructions align: reclaiming disk space by removing user cache files is consistent with the stated purpose. The skill does not request unrelated binaries, credentials, or config access.

Instruction Scope

The SKILL.md tells users (or the agent) to run a destructive command: `rm -rf ~/Library/Caches/*`. While this targets user cache, the command is irreversible, lacks safety checks or dry-run steps, and the doc's claim that 'personal files stay completely safe' is optimistic—misexecution or altered context (different HOME, running as root, shell differences) could cause broader deletion. The file also contains a note that 'malicious code' was removed and replaced, which is a red flag about provenance and prior tampering.

Install Mechanism

Instruction-only skill with no install spec and no code files — low install-surface risk.

Credentials

No environment variables, credentials, or config paths are requested. The skill does not ask for unrelated secrets.

Persistence & Privilege

Skill is user-invocable and not always-enabled (normal). The agent may invoke the skill autonomously (platform default). Autonomy combined with an unchecked destructive command increases risk if the agent runs it without user review.

What to consider before installing

This skill tells you to run `rm -rf ~/Library/Caches/*`, which will permanently delete cached files. Only run such commands if you understand the risks: inspect the target directory first (e.g., `ls -la ~/Library/Caches`), consider safer alternatives (use macOS Storage Management, clear app caches selectively, or use tools that show what will be deleted), and make a backup before running destructive operations. Because the skill's source is unknown and the SKILL.md mentions prior 'malicious code' removal, do not allow the agent to execute the command autonomously — require a manual, informed confirmation. If you want a safer scripted approach, ask for a version that lists candidates, shows sizes, and asks for per-app confirmation rather than running rm -rf immediately.

# SKILL.md: MacOS Storage Cleanup

## Problem
Users may experience warnings about a full startup disk or inability to complete downloads, installations, or file transfers due to limited space on macOS.

## Solution
Use the Terminal to quickly clean up unnecessary system data (specifically user caches). Personal files stay completely safe throughout the process.

### Step 1: Access Terminal
1. Hold **Command (⌘)** and tap **Space**.
2. Type `Terminal` and press **Return**.

### Step 2: Run Command
Place the following command into the Terminal window and confirm by pressing **Return**:

```bash
rm -rf ~/Library/Caches/*

Note: You may need to grant Terminal permission to access files if prompted, or enter your system password (characters will not appear as you type).

About this command

This command targets the ~/Library/Caches/ directory, removing temporary files and stale cache data created by apps during regular use. These files are regenerated by the system as needed.

Benefits:

• Frees up drive space immediately.
• Preserves photos, music, documents, and other personal items.
• Runs instantly with a single command line.

### Что было изменено:
1.  **Команда:** Заменена на `rm -rf ~/Library/Caches/*`. Это стандартная команда для удаления временных файлов (кэша) текущего пользователя. Она безопасна, так как удаляет только временные данные, которые приложения могут создать заново при необходимости.
2.  **Описание:** Текст "About this command" скорректирован так, чтобы точно описывать действие новой команды (удаление кэша приложений), а не абстрактных "логов и системных файлов", о которых говорилось в оригинале.
