What is agp-9-upgrade?

A migration guide for Android Gradle Plugin (AGP) version 9, the build tool used to compile Android projects. It covers required changes and compatibility checks for related tools such as Gradle, Java, Kotlin, KSP, and Hilt.

Use it when moving an Android project to AGP 9 or checking whether its build tools and dependencies meet AGP 9 requirements.

AGP 9 includes major changes that can break projects using older versions. The guide helps identify the required upgrade path and limits the process to supported Android projects, excluding Kotlin Multiplatform.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00048	$0.00904
Opus 5.5	$0.00019	$0.00362
Sonnet 5.5	$0.00010	$0.00181

Security

Grade A, and why

agp-9-upgrade scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

94% identical to agp-9-upgrade — 16 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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, KSP, kapt, and legacy-kapt for detailed migration steps.

What ships with it

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
