Over-Permissioned MCP Skill

Detects MCP skills that request or exercise permissions far exceeding what their stated function requires. A "spell checker" that requests filesystem write access, network access, and process execution is a strong signal of a trojaned or malicious skill. This rule monitors tool calls for permission-boundary violations.
