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
SKILL.md describes Google Sheets tool calls (e.g., GOOGLESHEETS_SEARCH_SPREADSHEETS and GOOGLESHEETS_BATCH_GET) that operate on user-provided spreadsheet names/ranges, meaning the agent ingests free text coming from outsider-controlled cells/worksheets without an initial selection/allowlist step.
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 explicitly requires adding the MCP server https://rube.app/mcp and calling RUBE_SEARCH_TOOLS at runtime to fetch tool schemas, which directly control the agent's available tools/instructions and are required for the skill to run.
