explain

This skill should be used when the user asks to "explain security concept", "what is OWASP", "explain this finding", "what does this vulnerability mean", "explain stride", "explain injection", "what is CSRF", "explain spoofing", "what does INJ-003 mean", "compare stride vs pasta", or asks any question about security terminology, frameworks, vulnerability categories, or specific findings. Works at framework, category, finding, and comparison levels.
