  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • 4 bundled files

    Scripts, templates, and references the model can read while it works. Files are read-only and never executed.

  • Open source

    Published by android on GitHub. Read the source before you install it.

Installation

Install the Agp 9 Upgrade AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.
2

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/android/skills.git /tmp/skills
mkdir -p .claude/skills
cp -r /tmp/skills/build-system/agp/agp-9-upgrade .claude/skills/agp-9-upgrade
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Agp 9 Upgrade in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Agp 9 Upgrade on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Agp 9 Upgrade is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

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.

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:

  1. android.builtInKotlin
  2. android.newDsl
  3. android.uniquePackageNames
  4. 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=false to gradle.properties.
  • When verifying changes, don't run the clean task. This is a waste of time.

Verification

After migration, verify the following:

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

Troubleshooting

Paparazzi v2.0.0-alpha04 and lower versions have issues with AGP 9. See references/paparazzi-gradle-9.md for details.

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Agp 9 Upgrade AI skill do?

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.

Why use Agp 9 Upgrade on TypingMind?

Because you install it once and use it with any model. Agp 9 Upgrade is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Agp 9 Upgrade in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/android/skills/tree/main/build-system/agp/agp-9-upgrade. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Agp 9 Upgrade?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Agp 9 Upgrade?

As many as you like. As long as a model supports skills, you can use Agp 9 Upgrade with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Agp 9 Upgrade AI skill free?

Yes. It is published on GitHub by android under the Apache-2.0 license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
