CRITICAL E005: Suspicious download URL detected in skill instructions.

• Suspicious download URL detected (high risk: 0.80). Although the hosts are GitHub (legitimate), these URLs include direct raw .sh installer links, a forked repo, and unresolved ${REPO} placeholders—patterns (curl|sh, raw script execution, forks/unknown accounts) that are commonly used to distribute malware unless you manually audit the script and verify the upstream release signatures.

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

• Potentially malicious external URL detected (high risk: 1.00). The skill's installer is invoked at runtime and explicitly runs remote code (curl -fsSL https://raw.githubusercontent.com/akillness/rtk/refs/heads/master/install.sh | sh) and also supports cargo install --git https://github.com/akillness/rtk, both of which fetch and execute external code that the skill relies on.
