Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Mobile Android Guides for building native Android apps, most of them from the Android team (`android/skills`). Cross-platform topics live in their own skills and have Android references there: architecture in `mobile-architecture`, tests in `mobile-test`, debugging (Gradle, crashes, ANRs) in `mobile-debug`, code review in `mobile-code-review`, security in `mobile-security` and Firebase in `mobile-firebase`. ## Pick the topic | Topic | Read | |---|---| | UI and navigation | [references/ui.md](references/ui.md) | | Build, performance and tooling | [references/build-and-performance.md](references/build-and-performance.md) | | Google Play | [references/play.md](references/play.md) | | Identity | [references/identity.md](references/identity.md) | | Camera and media | [references/media.md](references/media.md) | | On-device AI | [references/on-device-ai.md](references/on-device-ai.md) | | Other form factors | [references/devices.md](references/devices.md) | Each topic file lists its guides; open only the ones the task needs. ## Before writing code …

This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
