Security
1 critical severity finding. Installing this skill is not recommended: please review these findings carefully if you do intend to do so.
E006: Malicious code pattern detected in skill scripts.
What this means
Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.
Why it was flagged
The skill instructs adding a third-party MCP endpoint that orchestrates OAuth and Outlook operations (including searching/downloading messages, attachments, contacts, and calendars), which creates a high risk of data exfiltration and OAuth token/credential capture by the remote server.
Low
Low-risk findings.
2 low severity findings. Worth noting, but not necessarily harmful.
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
Required runtime workflow uses Rube MCP Outlook tools to read user mailbox content by executing `OUTLOOK_SEARCH_MESSAGES`/`OUTLOOK_QUERY_EMAILS` and optionally `OUTLOOK_GET_MESSAGE` and attachment download, so outsider-authored email bodies/subjects can be ingested when searching/reading across the account.
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
The skill requires adding and using the MCP server endpoint https://rube.app/mcp at runtime (see RUBE_SEARCH_TOOLS / RUBE_MANAGE_CONNECTIONS calls) which fetches tool schemas from that remote server that directly influence the agent's available tools and behavior.
