Zero-Day: Vulnerability Research & Discovery

Systematic methodology for finding novel, undisclosed vulnerabilities in source code, compiled binaries, and live systems. This skill guides the research process from intelligence gathering through proof-of-concept development to responsible disclosure.

This is the discovery skill - it finds vulnerabilities nobody has catalogued yet. For exploiting known weaknesses on live systems, use lockpick. For scanning code against known vulnerability patterns, use security-audit.
