Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00051 | $0.00674 |
| Opus 5 | $0.00026 | $0.00337 |
| Sonnet 5 | $0.00010 | $0.00135 |
| Haiku 4.5 | $0.00005 | $0.00067 |
Grade A, and why
android-agp-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 9d 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.

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-kaptas 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:
android.builtInKotlinandroid.newDslandroid.uniquePackageNamesandroid.enableAppCompileTimeRClass
Guidelines
- Never write or run Python scripts for build migration.
- Never add
android.disallowKotlinSourceSets=falsetogradle.properties. - Do not run
cleantask when verifying — it wastes time.

What ships with it
3 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.
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.

android-agp-upgrade is a skill published in the GitHub repository HoangNguyen0403/agent-skills-standard (565 stars, last pushed 3d ago), licensed MIT. It adds 51 tokens to every session and 674 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
