Reviewing Changes - Android Additions

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

Instructions

IMPORTANT: Work systematically through each step before providing feedback. Each checklist file includes structured thinking guidance for its review passes.

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

Android metadata checks — flag as ❓ if any of these are missing:

• PR includes *Screen.kt or Composable changes but has no screenshots
• PR adds new ViewModel or Repository but has no test plan or test file changes

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:

• Re-reviews → invoke reviewing-incremental-changes agent skill; scope to changed lines only, do not flag new issues in unchanged code
• 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 (project-specific) → reference/style-patterns.md (Kotlin rules enforced in review)
• Style questions (general) → docs/STYLEANDBEST_PRACTICES.md

Core Principles

• Priority order: Security → Correctness → Breaking Changes → Performance → Maintainability
• 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
