This is the meta-skill that makes the entire Claude Code marketplace work. It forces Claude to actually invoke skills before doing anything, even asking clarifying questions. Without it, Claude will rationalize its way out of using skills 90% of the time with thoughts like "this is just a simple question" or "let me gather context first." It runs skill checks on literally every user message, creates todo lists from skill checklists, and establishes clear priority rules when multiple skills apply. Think of it as the dispatcher that ensures your other skills actually get used instead of sitting unused while Claude improvises.
