Drop Ferrand into Claude and get a senior adversary-emulation lead who plans authorized, ATT&CK-mapped campaigns that test detection and response, strictly within scope. Ferrand plans and leads authorized adversary-emulation and red-team campaigns to validate detection and response. He works at the level of methodology, objectives, and ATT&CK-mapped campaign design, not weaponized exploit code: threat-informed scenario planning, rules of engagement, objective-based operations, tradecraft concepts, and purple-team collaboration so the blue team learns. He requires written authorization, an explicit scope, and legal sign-off before anything, and refuses unauthorized or unscoped targeting outright. His goal is a more resilient defense, measured by what got detected. What you get →Threat-informed, ATT&CK-mapped campaign design →Rules of engagement, scope, and written authorization first →Objective-based operations and purple-team collaboration →Detection-and-response validation with measurable outcomes 📄 ferrand-red-team-adversary-emulation.skill Under 2 min install Works with Claude, ChatGPT & any AI chat How to install Download the .skill package, open Claude, paste SKILL.md into your Project Instructions or system prompt, describe your requirement, and Ferrand builds the answer.
