What it does
Agp 9 Upgrade is an agent skill from arindamxd/camerax-android. Upgrades, or migrates, an Android project to use Android Gradle Plugin (AGP) version 9. Do not use this skill for migrating Kotlin Multiplatform (KMP) projects.
Its SKILL.md is about 880 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/buildconfig.md`, `references/ksp-kapt.md` and `references/paparazzi-gradle-9.md`).
It sits in Mobile, covering Android development, Cross-platform mobile apps and Code migrations. It works with Android, Gradle and Kotlin. The repository describes itself as: A Play Store camera app showing Jetpack CameraX APIs in Kotlin — install it, use it, copy the patterns. The licence is Apache-2.0.
When your agent uses it
- Migrating Kotlin Multiplatform (KMP) projects
- Tasks that involve Android development
- Tasks that involve Cross-platform mobile apps
Example prompts
- “/agp-9-upgrade”
Requirements
- Python 3
Workflow steps
6 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 7c36352. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Agp 9 Upgrade loads about 883 tokens when it runs, and up to ~2.6k if it reads all its reference files. Until then it costs about 44 tokens; SKILL.md has 417 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Migration guide
See the AGP 9 migration guide for the major changes, many breaking, in AGP 9 compared to AGP 8.
Requirements
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.
Steps
If AGP is already at 9 or higher, then do the following:
Step 1: Update dependencies
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.
Step 2: Migrate to built-in Kotlin
See the guide for detailed information.
Step 3. Migrate to the new AGP DSL
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.
Show full SKILL.md (149 more words)Show less
Step 4. Migrate kapt to KSP or legacy-kapt
If KSP (com.google.devtools.ksp) or kapt (org.jetbrains.kotlin.kapt) are used in the project, see KSP, kapt, and legacy-kapt for detailed migration steps.
Step 5. BuildConfig
If any Android module contains custom BuildConfig fields, see BuildConfig for detailed information.
Step 6. Update gradle.properties
After the migration, check gradle.properties. Remove the following flags:
- android.builtInKotlin
- android.newDsl
- android.uniquePackageNames
- android.enableAppCompileTimeRClass
Additionally, delete all temporary files you've created.
Guidelines
- Never write or run python scripts.
- Only search the Gradle dependency cache when inspecting external dependencies, and only as a last resort.
- Never add
android.disallowKotlinSourceSets=falsetogradle.properties. - When verifying changes, don't run the
cleantask. This is a waste of time.
Verification
After migration, verify the following:
- Gradle IDE sync succeeds.
./gradlew helpsucceeds../gradlew build --dry-runsucceeds.
Troubleshooting
Paparazzi v2.0.0-alpha04 and lower versions have issues with AGP 9. See references/paparazzi-gradle-9.md for details.
