Security audit

Sizeup

Security checks across malware telemetry and agentic risk

Overview

Sizeup is a straightforward local disk-usage tool that lists file and folder sizes for paths the user chooses to scan.

Install only if you are comfortable with the agent seeing file and directory names, paths, sizes, and extension summaries for folders you ask it to scan. Prefer specific cleanup directories or projects, and avoid scanning your whole home directory or system root unless that is intentional.

Finding
The skill description indicates it analyzes disk usage for arbitrary paths, which necessarily involves reading the filesystem, but the skill declares no corresponding permissions. That creates a real least-privilege and transparency issue: users and enforcement systems are not informed that the skill can access local files and directory metadata, increasing the chance of unintended exposure of sensitive paths.
