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

• Potentially malicious external URL detected (high risk: 1.00). The installation instructions run "npx skills add https://github.com/nangongwentian-fe/jay-skills" which fetches and executes remote repository content whose install script writes rule blocks into ~/.codex/AGENTS.md that are loaded into every conversation and thus directly control agent prompts.
