The skill uses Bash with bun to execute a TypeScript script that fetches a URL and parses meta tags. While the described actions are safe (read-only web analysis), the use of bun to run arbitrary local code introduces a risk if the script were compromised. No signs of obfuscation, data exfiltration, or destructive commands in the instructions.

Points d'attention
  • Runs a local TypeScript script via bun, which could potentially execute arbitrary code if the script is malicious; however, the intended behavior is benign web page analysis.
