shipit: Skill for Claude Code

.agents/skills/android-build/SKILL.md

android-build is a skill for Claude Code, Codex from nikzlabs/shipit. It costs 101 tokens per session (1,176 once invoked), scanned A, original, Apache-2.0.

A skill for building, checking, and previewing Android applications made with Kotlin or Java. It covers Gradle builds, code checks, automated tests, and image-based checks of the app’s screens, with optional emulator access.

In plain words
What is it for?
Use it for Android or Gradle projects, including apps in a monorepo—a repository containing several projects—and projects using Jetpack Compose, Android’s Kotlin UI toolkit.
Why use it?
It gives an Android project a defined loop for finding build errors, code and accessibility problems, test failures, and visual changes.

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-build 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 1mo 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 — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Android build, test & preview

The Android toolchain is baked into every session container — JDK 17, the Android SDK, and Gradle 8.7 are always on PATH. A repo declares nothing to build (no shipit.yaml Android fields). Full command reference and env paths: /shipit-docs/android.md — read it for anything not covered here.

There are two surfaces: headless (build/lint/test/snapshot — this container, no device) and a running app (an emulator Compose service over adb).

Find the Gradle root first

Run Gradle from the dir with settings.gradle(.kts) + gradlew. In a monorepo (web app + an android/ module) just cd into it. If there are several Android app modules, flavors, or Gradle roots, list them and pick — or ask the user which to target. Don't guess off stray .gradle files.

cd android
./gradlew projects        # modules
./gradlew tasks --all     # available tasks (snapshot task names vary by library/variant)

The core loop: build → lint → snapshot

./gradlew assembleDebug   # did I break the build?
./gradlew lint            # manifest/resource/accessibility + edge-to-edge/inset checks
./gradlew test            # JVM unit tests (+ Robolectric if used)

Prefer the committed ./gradlew (pins the Gradle version). It downloads its dist once per fresh container; run the baked gradle to skip that if needed.

Reading the output is most of debugging — compile errors, lint findings, and test stack traces are in the command output. Fix the root cause from them.

"Did my UI/inset/padding change render right?" → a snapshot test

This is the key habit: visual verification is a snapshot test, not a screenshot of a running app. Snapshot tests (Paparazzi via layoutlib, Roborazzi via Robolectric) render a screen to a PNG on the JVM with no device, and the test sets up the data it renders — then diffs against a committed golden.

./gradlew verifyPaparazziDebug    # check renders against goldens (or verifyRoborazziDebug)
./gradlew recordPaparazziDebug    # regenerate goldens after an intended visual change

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.
