What are Android skills for agents?

Google has released official Android skills for AI coding agents on GitHub. Skills are modular, AI-optimized instruction sets that activate automatically when a prompt matches their metadata, eliminating the need to manually attach context for each task. The Android skills repository follows Google's official guidance and covers complex workflows like full Navigation 3 setup, edge-to-edge implementation with AGP 9, XML-to-Compose migrations, and R8 config analysis. The skills are integrated with Android CLI and compatible with any agent that supports the skills standard.
