ENFORCEMENT: Strictly reviews and enforces Android code architecture. Mandatory Clean Architecture, UI passivity, and ViewModel responsibilities.
ENFORCEMENT: Scaffolds a complete feature by orchestrating all Guardian standards. Focuses on workflow and placement.
ENFORCEMENT: Implements a systematic refactoring cycle to fix architecture violations and improve testability while maintaining test stability.
ENFORCEMENT: Strictly configures GitHub Actions CI and coverage. Mandatory analysis of project DSL, DI, and structure before implementation.
ENFORCEMENT: Strictly reviews and enforces Android project modularization. Mandatory dependency direction, module types, and documentation rules.
ENFORCEMENT: Analyzes code for testability risks. Strictly eliminates hidden dependencies, non-determinism, and global state. Enforces Resource-First UI patterns and architectural boundaries in Jetpack Compose.

See the AGP 9 migration guide for the major changes, many breaking, in AGP 9 compared to AGP 8.
If the user requests to update or migrate to AGP 9, first check the AGP version used in the project. If it is lower than 9, stop and ask the user to run the AGP Upgrade Assistant in Android Studio to update to the latest stable version of AGP, and confirm when done. The user may also request that this requirement be skipped; if this is the case, you should update the version of AGP to the latest stable version as part of the AGP 9 migration. See the AGP 9 migration guide for how to do this.
Each version of AGP has its own set of compatibilities with other tools, such as Gradle, JDK, and Kotlin. The release notes for each of these versions will include a Compatibility table indicating the minimum versions for these tools.
Do not use this skill for KMP projects, as they are unsupported.
If AGP is already at 9 or higher, then do the following:
If KSP (com.google.devtools.ksp) is used in the project, ensure it is on
version 2.3.6 or higher.
If Hilt is used in the project, ensure it is on version 2.59.2 or higher.
See the guide for detailed information.
See the guide for detailed information.
See also gradle-recipes for examples on how to migrate old code to code that is compatible with AGP 9 and the new DSL.
If KSP (com.google.devtools.ksp) or kapt (org.jetbrains.kotlin.kapt) are
used in the project, KSP, kapt, and legacy-kapt
for detailed migration steps.
If any Android module contains custom BuildConfig fields, see BuildConfig for detailed information.
After the migration, check gradle.properties. Remove the following flags:
Additionally, delete all temporary files you've created.
android.disallowKotlinSourceSets=false to gradle.properties.clean task. This is a waste of time.After migration, verify the following:
./gradlew help succeeds../gradlew build --dry-run succeeds.Paparazzi v2.0.0-alpha04 and lower versions have issues with AGP 9. See references/paparazzi-gradle-9.md for details.
