name: reviewing-changes version: 3.0.0 description: Guides Android code reviews with type-specific checklists and MVVM/Compose pattern validation. Use when reviewing Android PRs, pull requests, diffs, or local changes involving Kotlin, ViewModel, Composable, Repository, or Gradle files. Triggered by "review PR", "review changes", "check this code", "Android review", or code review requests mentioning bitwarden/android. Loads specialized checklists for feature additions, bug fixes, UI refinements, refactoring, dependency updates, and infrastructure changes.

Reviewing Changes - Android Additions

This skill provides Android-specific workflow additions that complement the base bitwarden-code-reviewer agent standards.

Instructions

IMPORTANT: Use structured thinking throughout your review process. Plan your analysis in <thinking> tags before providing final feedback.

Step 1: Retrieve Additional Details

Retrieve any additional information linked to the pull request using available tools (JIRA MCP, GitHub API).

If pull request title and message do not provide enough context, request additional details from the reviewer:

• Link a JIRA ticket
• Associate a GitHub issue
• Link to another pull request
• Add more detail to the PR title or body

Step 2: Detect Change Type with Android Refinements

Use the base change type detection from the agent, with Android-specific refinements:

Android-specific patterns:

• Feature Addition: New ViewModel, new Repository, new @Composable functions, new *Screen.kt files
• UI Refinement: Changes only in *Screen.kt, *Composable.kt, ui/ package files
• Infrastructure: Changes to .github/workflows/, gradle/, build.gradle.kts, libs.versions.toml
• Dependency Update: Changes only to libs.versions.toml or build.gradle.kts with version bumps

Step 3: Load Appropriate Checklist

Based on detected type, read the relevant checklist file:

• Dependency Update → checklists/dependency-update.md (expedited review)
• Bug Fix → checklists/bug-fix.md (focused review)
• Feature Addition → checklists/feature-addition.md (comprehensive review)
• UI Refinement → checklists/ui-refinement.md (design-focused review)
• Refactoring → checklists/refactoring.md (pattern-focused review)
• Infrastructure → checklists/infrastructure.md (tooling-focused review)

The checklist provides:

• Multi-pass review strategy
• Type-specific focus areas
• What to check and what to skip
• Structured thinking guidance

Step 4: Execute Review Following Checklist

Follow the checklist's multi-pass strategy, thinking through each pass systematically.

Step 5: Consult Android Reference Materials As Needed

Load reference files only when needed for specific questions:

• Issue prioritization → reference/priority-framework.md (Critical vs Suggested vs Optional)
• Phrasing feedback → reference/review-psychology.md (questions vs commands, I-statements)
• Architecture questions → reference/architectural-patterns.md (MVVM, Hilt DI, module org, error handling)
• Security questions (quick reference) → reference/security-patterns.md (common patterns and anti-patterns)
• Security questions (comprehensive) → docs/ARCHITECTURE.md#security (full zero-knowledge architecture)
• Testing questions → reference/testing-patterns.md (unit tests, mocking, null safety)
• UI questions → reference/ui-patterns.md (Compose patterns, theming)
• Style questions → docs/STYLE_AND_BEST_PRACTICES.md

Core Principles

• Appropriate depth: Match review rigor to change complexity and risk
• Specific references: Always use file:line_number format for precise location
• Actionable feedback: Say what to do and why, not just what's wrong
• Efficient reviews: Use multi-pass strategy, skip what's not relevant
• Android patterns: Validate MVVM, Hilt DI, Compose conventions, Kotlin idioms
