pp-hackernews

MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).

• Third-party content exposure detected (high risk: 0.90). The skill's commands like hackernews-pp-cli sync, stories, items, pulse, and repost explicitly pull public Hacker News and Algolia content (user-generated stories/comments) into the agent's workflow (see the "sync", "stories", "pulse", and "repost" examples in SKILL.md), so untrusted third-party content can materially influence tool decisions.

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

• Potentially malicious external URL detected (high risk: 0.80). This skill requires installing and running remote code at runtime (installation fallback and MCP install), e.g. the npm installer "npx -y @mvanhorn/printing-press install hackernews --cli-only" and the Go install "go install github.com/mvanhorn/printing-press-library/library/media-and-entertainment/hackernews/cmd/hackernews-pp-cli@latest", which fetch and install executables the agent may run—so they're runtime external dependencies that execute remote code.
