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 requires calling GitHub toolkit endpoints that fetch and ingest public, user-generated GitHub content (e.g., GITHUB_SEARCH_CODE, GITHUB_GET_REPOSITORY_CONTENT, GITHUB_LIST_REPOSITORY_ISSUES) as part of required workflows, so external repo/issue/PR content can influence subsequent tool decisions (merges, dispatches) and enable indirect prompt injection.

Medium

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 adding and calling the MCP endpoint https://rube.app/mcp at runtime (via RUBE_SEARCH_TOOLS) to fetch tool schemas that directly determine the agent's available instructions and behavior, so this external URL can control prompts and execution.
