2 findings — 2 medium severity. This skill can be installed but you should review these findings before use.
W011: Third-party content exposure detected (indirect prompt injection risk)
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
Third-party content exposure detected (high risk: 0.90). The SKILL.md explicitly instructs the agent to call GMAIL_FETCH_EMAILS and GMAIL_FETCH_MESSAGE_BY_MESSAGE_ID (see "Search and Filter Emails" and "Reply to a Thread") to retrieve full message payloads and attachments from users' mailboxes, clearly ingesting arbitrary user-generated/untrusted email content that can influence subsequent tool use and decisions.
W012: Unverifiable external dependency detected (runtime URL that controls agent)
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
Potentially malicious external URL detected (high risk: 0.90). The skill explicitly requires connecting to the Rube MCP server at https://rube.app/mcp and calling RUBE_SEARCH_TOOLS at runtime to fetch tool schemas that directly determine available agent tools/instructions, so this external endpoint can control agent behavior.
