Resize and add a still image (science/nav icon, city or station sprite, terrain, UI art) into Assets.xcassets. OpenArt/Midjourney exports are huge and MUST be resized first. Use when Marina says "add this icon", "add art for X", "put this image in the assets", "/add-art-asset", or drops a PNG that needs wiring into the app. For animated GIFs / video → sprite frames, use /extract-frames instead.
Create a new Read-to-Earn lesson (readings, fun facts, questions, fill-in-blanks, environment prompts) for a building, following the established LessonContent pattern. Use when Marina says "write a lesson for X", "add a building lesson", "/add-building-lesson", or a building has no lesson content yet.
Author knowledge cards for a building across cityMap/workshop/forest/craftingRoom environments. Use when Marina says "add cards for X", "write knowledge cards", "author discovery cards", "/add-knowledge-cards", or a building has lessons but no knowledge cards yet.
Register a new Swift file into the Xcode project (project.pbxproj) so it compiles. Use when a new .swift file was created (or needs creating) and Xcode doesn't see it yet, or when the user says "add this file to the project", "wire it into the build", "/add-swift-file", or a new file causes "cannot find X in scope" / "no such module" build errors.
Audit and fix layout sizing across all Apple device sizes (iPhone SE to iPad Pro). Use when Marina says "looks wrong on iPhone", "fix the iPad layout", "text is truncated/cut off", "it's cramped on small screens", "audit the sizing", or a view breaks on a specific device.
Build RenaissanceArchitectAcademy locally to verify a change against the real app. Defaults to macOS (fastest dev loop); switch to iPad Simulator for iOS-specific behavior (SwiftUI sheet quirks, App Attest, on-device touches).
Proactively teach coding concepts during development, MIT-style. Saves all lessons to Teaching.md.
