CRITICAL E005: Suspicious download URL detected in skill instructions.

• Suspicious download URL detected (high risk: 0.70). These URLs include an unofficial personal proxy domain (k-skill-proxy.nomadamas.org, including a malformed variant) and links to an unknown GitHub repo used to distribute/execute code (the repo is referenced by an npx invocation), which presents a supply-chain/remote-code risk; the official data.go.kr links are benign and not flagged.

MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 0.90). The skill's SKILL.md requires running "npx -y @nomadamas/k-skill@0 instruct korean-holiday-calendar", which fetches and executes a remote npm package at runtime and whose output is explicitly the primary instructions for the skill.
