circle-png-image

PassAudited by ClawScan on May 3, 2026.

Overview

This skill appears coherent and benign: it converts user-specified PNG files into circular PNGs using a small local Python script.

This skill is safe to use for local PNG conversion. Before installing, note that it depends on Pillow and will write an output image where you specify; use a virtual environment and avoid --force unless you mean to overwrite an existing file.

#ASI04: Agentic Supply Chain Vulnerabilities

What this means

Installing the skill may install the current Pillow package version from the package source rather than a reviewed fixed version.

Why it was flagged

The skill depends on Pillow for image processing, and the dependency is declared, but the artifact does not pin a package version.

Skill content

install:
      - kind: uv
        package: pillow

Recommendation

Install in a virtual environment when possible and rely on trusted package indexes; pin Pillow if you need reproducible or audited installs.

Info

#ASI02: Tool Misuse and Exploitation

What this means

The skill can create or overwrite local files at the output path if directed to do so.

Why it was flagged

The script creates directories and writes the output PNG, while refusing to overwrite an existing output file unless --force is used.

Skill content

if args.output.exists() and not args.force: ... return 2 ... output_path.parent.mkdir(parents=True, exist_ok=True) ... save(output_path, format="PNG")

Recommendation

Check the output path before running, and only use overwrite/--force when you intentionally want to replace an existing file.
