What is build-tooling?

A set of Android build-system instructions for Gradle Kotlin projects. It covers dependency version catalogs, code generation, reusable build conventions, app modules, and release shrinking.

Use it when setting up or reviewing Android build files, centralizing library versions, organizing modules, configuring KSP, or preparing optimized release builds.

It keeps build configuration consistent and makes dependency updates and multi-module projects easier to manage.

Install

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.

Clone the repo

git clone --depth 1 https://github.com/RanaNadeemAslam/android-ai-skills

Made for: Cursor.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.

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	$0.00000	$0.02060
Opus 5	$0.00000	$0.01030
Sonnet 5	$0.00000	$0.00412
Haiku 4.5	$0.00000	$0.00206

Security

Grade A, and why

build-tooling 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 8d 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.

You are an expert in Android build systems. Use Gradle Kotlin DSL, version catalogs, and convention plugins. Optimize for build speed and maintainability.

Gradle Kotlin DSL

DO:

Use .gradle.kts (Kotlin DSL) for all build files
Use libs.versions.toml for centralized dependency management

DON'T:

Use Groovy .gradle files in new projects
Hardcode dependency versions in build files

Version Catalog

Source: https://developer.android.com/build/migrate-to-catalogs

DO:

Define all dependencies in gradle/libs.versions.toml:

[versions]
kotlin = "2.1.0"
compose-bom = "2025.04.00"
hilt = "2.51.1"
room = "2.7.1"
coroutines = "1.10.1"
ksp = "2.1.0-1.0.29"

[libraries]
compose-bom = { group = "androidx.compose", name = "compose-bom", version.ref = "compose-bom" }
compose-ui = { group = "androidx.compose.ui", name = "ui" }
compose-material3 = { group = "androidx.compose.material3", name = "material3" }
compose-ui-tooling-preview = { group = "androidx.compose.ui", name = "ui-tooling-preview" }
lifecycle-runtime-compose = { group = "androidx.lifecycle", name = "lifecycle-runtime-compose", version = "2.9.0" }
hilt-android = { group = "com.google.dagger", name = "hilt-android", version.ref = "hilt" }
hilt-compiler = { group = "com.google.dagger", name = "hilt-android-compiler", version.ref = "hilt" }

room-runtime = { group = "androidx.room", name = "room-runtime", version.ref = "room" }
room-ktx = { group = "androidx.room", name = "room-ktx", version.ref = "room" }
room-compiler = { group = "androidx.room", name = "room-compiler", version.ref = "room" }
datastore-preferences = { group = "androidx.datastore", name = "datastore-preferences", version = "1.1.4" }

coil-compose = { group = "io.coil-kt.coil3", name = "coil-compose", version = "3.1.0" }

[plugins]
android-application = { id = "com.android.application", version = "8.9.0" }
android-library = { id = "com.android.library", version = "8.9.0" }
kotlin-android = { id = "org.jetbrains.kotlin.android", version.ref = "kotlin" }

ksp = { id = "com.google.devtools.ksp", version.ref = "ksp" }
room = { id = "androidx.room", version.ref = "room" }

Reference with libs.xyz in build files:

dependencies {
    implementation(platform(libs.compose.bom))
    implementation(libs.compose.ui)
    implementation(libs.compose.material3)
    implementation(libs.hilt.android)
    ksp(libs.hilt.compiler)
}

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.

build-tooling is a cursor rule published in the GitHub repository RanaNadeemAslam/android-ai-skills (6 stars, last pushed 5mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,060 tokens. 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 2026-08-31.
