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's required workflows call Calendly toolkit endpoints (e.g., CALENDLY_LIST_EVENTS, CALENDLY_LIST_EVENT_INVITEES, CALENDLY_GET_EVENT) to fetch and interpret event and invitee data from users' Calendly accounts (third-party, user-generated content) and then use that data to decide and perform actions like cancellations or invitations, which could allow indirect instruction injection.
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 requires connecting to the MCP endpoint https://rube.app/mcp and explicitly instructs calling RUBE_SEARCH_TOOLS to fetch current tool schemas at runtime, so content fetched from that URL can directly control agent prompts/tool behavior.
