x-bookmarks-manager

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

• Third-party content exposure detected (high risk: 0.85). The skill runs bird bookmarks --json and passes the resulting JSON to the agent for summarization; that JSON is fetched from X (an outsider-authored source) at runtime and becomes LLM-readable content.

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

• Potentially malicious external URL detected (high risk: 0.80). The skill's setup script performs a network install of the third‑party package @steipete/bird via npm (npm install --prefix "$NODE_PREFIX" @steipete/bird), which will fetch remote code from the npm registry (and is linked to https://github.com/steipete/bird) and then the skill executes the installed bird binary at runtime, so remote code is fetched and executed.
