Scaffold and author content for the microsoft/agent-academy GitHub repo. Use this skill whenever the user wants to create a new mission, lab, or module for Agent Academy — whether that's a course mission (Recruit, Operative, Commander) or a standalone Special Ops mission. Trigger whenever the user says "write a mission", "scaffold a lab", "create a Special Ops", "new Agent Academy module", or describes an agent-building concept they want to turn into a hands-on lesson. Also trigger when the user says "add a module to agent academy", "I want to contribute a mission", or asks about badge creation for Special Ops. This skill handles: repo structure lookup, duplicate detection, mission naming, markdown scaffolding, step-by-step content drafting, cross-linking, tag/category suggestions, difficulty rating, and badge image generation for Special Ops missions.
