What it does

Android Agp Upgrade is an agent skill from HoangNguyen0403/agent-skills-standard. Upgrade an Android project to Android Gradle Plugin (AGP) 9. Use when migrating to AGP 9, updating Gradle build files, migrating to built-in Kotlin, or adopting the new AGP DSL.

Its SKILL.md is about 670 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `evals/evals.json`, `references/built-in-kotlin.md` and `references/dsl-migration.md`).

It sits in Mobile, covering Android development. It works with Android, Gradle and Kotlin. The repository describes itself as: A collection of Agent Skills Standard and Best Practice for Programming Languages, Frameworks that help our AI Agent follow best practies on frameworks and programming laguages. The licence is MIT.

When your agent uses it

  • Migrating to AGP 9
  • Updating Gradle build files
  • Migrating to built-in Kotlin
  • Adopting the new AGP DSL

Example prompts

  • “/android-agp-upgrade”

Requirements

  • Python 3

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Update dependencies
  2. Migrate to built-in Kotlin
  3. Migrate to the new AGP DSL
  4. Migrate kapt to KSP or legacy-kapt
  5. Update BuildConfig
  6. Clean up gradle.properties

What it can do on your machine

Read from SKILL.md and the folder at commit b529c2d. 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

Android Agp Upgrade loads about 668 tokens when it runs, and up to ~1.7k if it reads all its reference files. Until then it costs about 49 tokens; SKILL.md has 267 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~49
When it runs · the whole SKILL.md, loaded when a task matches
~668
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.7k

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.

AGP 9 Upgrade Workflow

Priority: P1 (HIGH)

Step-by-step workflow for upgrading an Android project to AGP 9.

Prerequisites

  • Check current AGP version. If below 8.x, recommend running the AGP Upgrade Assistant in Android Studio first.
  • Do NOT use this skill for Kotlin Multiplatform (KMP) projects.
  • Verify Gradle, JDK, and Kotlin version compatibility with AGP 9 release notes.

Step 1: Update dependencies

  • If KSP (com.google.devtools.ksp) is used, ensure version 2.3.6+.
  • If Hilt is used, ensure version 2.59.2+.
  • Update AGP to the latest stable 9.x version in the project's build files.

Step 2: Migrate to built-in Kotlin

AGP 9 includes built-in Kotlin support — the org.jetbrains.kotlin.android plugin is no longer needed.

See migration guide for detailed steps.

Step 3: Migrate to the new AGP DSL

AGP 9 introduces a new DSL for android {} blocks. Key changes include namespace handling, build type configuration, and source set declarations.

See DSL migration for before/after examples.

Step 4: Migrate kapt to KSP or legacy-kapt

If the project uses kapt:

  • Prefer migrating to KSP where annotation processors support it (Room, Hilt, Moshi).
  • For processors without KSP support, use legacy-kapt as a bridge.

Step 5: Update BuildConfig

If any module uses custom BuildConfig fields, update to the new AGP 9 syntax.

Step 6: Clean up gradle.properties

Remove these flags after migration:

  1. android.builtInKotlin
  2. android.newDsl
  3. android.uniquePackageNames
  4. android.enableAppCompileTimeRClass

Guidelines

  • Never write or run Python scripts for build migration.
  • Never add android.disallowKotlinSourceSets=false to gradle.properties.
  • Do not run clean task when verifying — it wastes time.

Verification

  1. ./gradlew help succeeds.
  2. ./gradlew build --dry-run succeeds.
  3. Gradle IDE sync succeeds.
