AppBootstrapAI: Skill for Claude Code

.claude/skills/android-gradle-architecture-pro/SKILL.md

android-gradle-architecture-pro is a skill for Claude Code from kelvinkosbab/AppBootstrapAI. It costs 74 tokens per session (1,399 once invoked), scanned A, original, MIT.

An Android Gradle build reviewer for multi-module projects, where an app is split into several smaller code modules. It checks shared build conventions, dependency versions, module relationships, and annotation-processing tools.

In plain words
What is it for?
Use it to review Gradle files, convention plugins, version catalogs, module dependency direction, Android Gradle Plugin and Kotlin versions, Compose compiler versions, and KSP versus kapt setup.
Why use it?
It helps reduce repeated build configuration and prevents inconsistent versions or unhealthy dependencies between modules. It also identifies uses of older processing approaches where a supported alternative is expected.

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.

Security

Grade A, and why

android-gradle-architecture-pro 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 10d 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.

How it starts

The opening of the file, as written. The whole thing — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Review Android Gradle build configuration for adherence to modern multi-module conventions. The reference pattern is Now in Android (NiA) — Google's official reference app — which factors all repeated android { ... } and dependency declarations into convention plugins under build-logic/convention/. Report only genuine problems; don't nitpick.

Review process:

  1. Inventory the build-file landscape using references/inventory.md — which files exist, what each is responsible for.
  2. Check the convention-plugin factoring using references/convention-plugins.md — is repeated config extracted? Where does it live?
  3. Validate version-catalog discipline using references/version-catalogs.md — no inline implementation("group:artifact:version") strings, no hardcoded versions in build.gradle.kts.
  4. Validate the multi-module graph using references/multi-module-graph.md:app + :feature:* + :data:* + :core:* shape, dependency direction.
  5. Check AGP / Kotlin / Compose-compiler co-versioning using references/agp-versioning.md.
  6. Verify KSP is used over kapt for all supported annotation processors using references/ksp-over-kapt.md.

If doing a partial review, load only the relevant reference files.

Core Instructions

  • Now in Android is the reference. When in doubt, check what NiA does. Their convention plugins under build-logic/convention/ are the canonical examples.
  • Convention plugins are non-negotiable past 3 modules. Once you have a :feature:home, :feature:settings, :feature:profile, the third repeated android { compileSdk = 34; defaultConfig { minSdk = 26; ... } } block is a smell. Factor.
  • Version catalogs are the single source of truth. Every version literal in a build.gradle.kts is a regression — there's always a [versions] entry it should reference.
  • AGP version is grounded in AGP 8.x for this skill. AGP 9 specifics are unverified; if the project uses AGP 9, defer to the actual release notes rather than this skill's guidance.
  • Don't suggest applying convention plugins where they're not warranted. A single-module app doesn't need build-logic/convention/. Convention plugins are a multi-module concern.
  • Don't introduce buildSrc/ for new code. The build-logic/ composite-build pattern superseded buildSrc because the latter invalidates Gradle's cache more aggressively. NiA uses build-logic; new projects should too.

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.
