Markdown → PDF converter with brand-pack support, watermarking, and CJK fonts
SaferSkills independently audited md-to-pdf (Agent Skill) and scored it 74/100 (yellow). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 3 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.
