W013: Attempt to modify system services in skill instructions.

What this means

The skill prompts the agent to compromise the security or integrity of the user’s machine by modifying system-level services or configurations, such as obtaining elevated privileges, altering startup scripts, or changing system-wide settings.

Why it was flagged

The skill explicitly instructs using "sudo xcrun mcp-server enable" to enable a headless MCP server (and references sudo opt-in elsewhere), which requests elevated privileges and can modify system state.

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

Source: Xcode MCP via `xcrun mcpbridge`/`xcrun mcp-server` is a runtime that can ingest outsider-authored free-text through the agent’s own prompt and tool parameters (e.g., `DocumentationSearch(query)`, `XcodeGrep(pattern)`, `XcodeUpdate(newString)`, and `DeviceInteractionSynthesize(interactionCommand)`), so untrusted user/agent text flows into the LLM/tool interaction without requiring preselection of a specific trusted item.
