Security audit

Youtube Subtitle Burner

Security checks across malware telemetry and agentic risk

Overview

This skill coherently helps users download YouTube videos, translate subtitles, and burn them into local MP4 files, with no evidence of hidden persistence, credential access, exfiltration, or destructive behavior.

Before installing, review the optional curl-based uv installer and local Clash proxy command, and run them only if you trust those tools and endpoints. Expect the skill to download YouTube content, install/use Pillow through uv, read the media/subtitle files you provide, and overwrite the output path you choose.
