Sizeup

Disk usage analyzer with tree view, large file finder, and extension breakdown. Like `du` but actually readable. Pure Python, zero dependencies.

Security Scan

The skill is internally consistent: it implements a local disk-usage analyzer in pure Python, requests no credentials or installs, and its instructions and code match the declared purpose.

Purpose & Capability

Name/description (disk usage analyzer) match the actual files and behavior: the included Python scripts scan directories, calculate sizes, list largest files, and produce JSON or a colored tree. No unrelated credentials, binaries, or network access are requested.

Instruction Scope

SKILL.md usage examples align with the code. Runtime instructions and code only read filesystem metadata and file sizes under the supplied path; they do not read arbitrary environment variables, contact external services, or attempt to modify system-wide settings.

Install Mechanism

No install/download steps are declared and no external packages are fetched. The skill is provided as source files (two copies of the same script) and runs as a local Python program — low install risk.

Credentials

The skill requires no environment variables, credentials, or config paths. All filesystem access is limited to the path argument provided at runtime; there are no requests for unrelated secrets or service tokens.

Persistence & Privilege

always is false and the skill does not attempt to persist configuration or modify other skills. It is user-invocable and may be invoked by the agent (normal platform behavior) but it has no elevated persistence or cross-skill configuration effects.

Assessment

This skill appears to be what it claims — a local disk-usage tool. Before running, note that it will traverse and read file sizes for every file under the path you give (it skips symlinks). Avoid running it as root on '/' unless you intend a full-system scan (it can be slow and will touch many files). The output includes file paths, so do not paste results into untrusted services if they might contain sensitive paths or filenames. If you want extra assurance, inspect the shipped sizeup.py yourself (it's plain, readable Python) — there is no network I/O or hidden behavior observed.

Usage

# Tree view of current directory
sizeup

# Analyze specific path
sizeup /var/log --depth 2

# Only show items >= 10MB
sizeup --min 10M

# Top 20 largest files
sizeup /home --top 20

# Extension breakdown
sizeup . --ext

# JSON output
sizeup --top 10 --json

Features

• Color-coded tree — red (≥1GB), yellow (≥100MB), cyan (≥10MB)
• Large file finder — --top N finds the biggest files fast
