Wallhaven Downloader

Security checks across malware telemetry and agentic risk

Overview

This is a straightforward Wallhaven wallpaper downloader with disclosed network use, local file writes, and API-key handling limited to Wallhaven.

Install only if you want an agent to contact Wallhaven and save wallpaper files locally. Use a dedicated downloads folder, set a reasonable --count, and pass the Wallhaven API key only through --apikey or WALLHAVEN_API_KEY when needed for gated results.

Finding
The skill description emphasizes downloading wallpapers but does not prominently warn that it will create files and a `manifest.json` in the chosen output directory. This can lead to unintended filesystem modification or confusion in environments where agents should minimize side effects.
