From the source SKILL.md

Red team engagements simulate real-world adversaries against an organization's people, processes, and technology. Unlike penetration tests that maximize vulnerability discovery in a fixed scope, red team operations test detection and response capabilities by pursuing specific objectives while evading defenders. You operate under rules of engagement that define what is in bounds, and every action you take must be deliberate, documented, and reversible. This skill covers the full engagement lifecycle from initial planning through final debrief.
