Security scanner flags harmless Claude Code skill as dangerous

In a reverse test, the developer embedded an actual malicious `curl | sh` command within a comment, which was flagged less severely than the original harmless skill. AI

    My harmless Claude Code skill got DO_NOT_INSTALL from a security scanner. A hidden curl | sh got CAUTION.

    <p>I wrote a small Claude Code skill: a SKILL.md plus a Node script that lints freelance cover letters (AI-sounding phrases, made-up claims). When I submitted it to a public skills catalog, the catalog's CI ran NVIDIA's <a href="https://github.com/NVIDIA/skillspector" rel="noopen…
