Available plugins

Plugin	Version	Description
android-review-plugin	1.0.0	Staff-level Android code review for Kotlin, Jetpack Compose, coroutines, memory leaks, architecture, and production-scale pitfalls

android-review

The flagship skill in this marketplace. Invoke /android-review in Claude Code to get a structured code review from a staff-engineer perspective, organized by severity:

• Blocking -- crashes, ANRs, memory leaks, data loss
• Warnings -- correctness issues, anti-patterns, deprecated APIs
• Suggestions -- idiomatic improvements and minor optimizations

Review categories

Category	Covers
Memory	Context leaks, view leaks, coroutine/Flow leaks, handler leaks
Coroutines	Dispatcher misuse, structured concurrency, Flow correctness, cancellation
Compose	Recomposition, side effects, state management, performance
Architecture	ViewModel boundaries, repository patterns, Hilt/DI scoping
Kotlin	Null safety, idioms, sealed type exhaustiveness, suspend correctness
Security	Logging PII, hardcoded secrets, WebView risks, intent safety
Lifecycle	Fragment observation, back handling, navigation timing
Threading	Main-thread IO, SharedPreferences, bitmap decoding
Testing	Testability, coroutine test patterns, implementation coupling
Gradle	Compose compiler/BOM mismatches, dependency scoping, ProGuard/R8, AGP/SDK levels

Quick start

# Review a feature branch against main
/android-review -branch feature/settings-refactor main

# Quick blocking-issues-only scan
/android-review -branch release/2.1 main -depth quick

# Focus on Compose issues only
/android-review -staged -focus compose

# Firefox for Android — loads Mozilla-specific patterns
/android-review -branch fenix-feature main -firefox

Flags

Flag	Description
-branch FEATURE BASE	Review diff between two branches
-file PATH	Review a single file
-staged	Review staged changes
-unstaged	Review working tree changes
-focus CATEGORY	Restrict to one category (memory, compose, coroutines, arch, kotlin, security, lifecycle, threading, testing, gradle)
-depth quick|full	quick = blocking only; full = complete review (default)
-firefox	Load Mozilla/Firefox for Android patterns
-message "TEXT"	Pass context to the reviewer
-no-save	Suppress the save-review prompt

See the full plugin documentation for details on the gather script, reference guides, and additional usage examples.

Reference guides

The skill includes specialized reference documents loaded contextually during review:

• Compose stability guide -- Compose compiler stability inference, recomposition bugs, remember vs rememberSaveable decision trees
• Mozilla Firefox patterns -- Firefox for Android (Fenix) project-specific conventions including Store/Action/Reducer/Middleware, Proto DataStore migration, and Hilt scoping

Requirements

• Python 3.10+ -- powers the diff-gathering script
• Git -- the project under review must be a git repository
• ktlint (optional) -- if available, style issues are reported separately from the code review
