name: elixir-ash-reviewer description: Comprehensive code review system for Elixir applications using Phoenix, LiveView, Ash Framework, LiveSvelte, TailwindCSS, and DaisyUI. Performs deep analysis of code quality, architectural patterns, test coverage, and Ash-specific best practices. Use when (1) Reviewing Elixir/Phoenix/Ash codebases for quality and best practices, (2) Analyzing test suite quality and brittleness, (3) Ensuring Ash framework patterns are properly implemented, (4) Identifying architectural improvements, (5) Reviewing LiveView/LiveSvelte component structure, (6) Validating resource design and API patterns

Elixir/Ash Stack Code Reviewer

Expert code review system for modern Elixir applications using Ash Framework, Phoenix, LiveView, and associated technologies.

Review Process

Phase 1: Codebase Analysis

1. Run scripts/analyze_codebase.py to get structure overview
2. Identify Ash resources, domains, and extensions
3. Map LiveView/LiveSvelte components
4. Catalog test coverage areas

Phase 2: Ash Framework Review

Resource Design

Review each Ash resource for:

• Attributes: Type safety, constraints, defaults
• Actions: CRUD completeness, custom actions appropriateness
• Calculations: Efficiency, loading strategy
• Relationships: Proper associations, join keys
• Policies: Authorization completeness, performance
• Changes: Hook placement, transaction boundaries
• Validations: Business rule coverage

Domain Architecture

• Domain boundaries and cohesion
• Public vs private resource exposure
• Extension usage (AshPhoenix, AshGraphql, AshJsonApi)
• Multi-tenancy implementation if applicable

For detailed Ash patterns, load: references/ash-patterns.md

Phase 3: Test Suite Analysis

Ash-Specific Testing

• Resource factory usage with ExMachina/Smokestack
• Changeset and action testing
• Policy testing with different actors
• Calculation and aggregate testing
• API boundary testing

Test Quality Indicators

• Setup/teardown patterns
• Async test safety
• Database sandbox usage
• Mock/stub appropriateness

For test standards, load: references/test-standards.md

Phase 4: LiveView/LiveSvelte Review

Component Architecture

• State management patterns
• PubSub usage and event handling
• Form changesets with AshPhoenix.Form
• Socket assigns optimization
• JavaScript hooks integration

LiveSvelte Integration

• Props passing patterns
• Store management
• Server/client state sync
• Bundle size considerations

Phase 5: Performance & Security

Ash Performance

• N+1 query detection
• Load statement optimization
• Pagination implementation
• Bulk action usage
• Cache strategy

Security Review

• Policy coverage gaps
• Input validation
• SQL injection prevention
• Authorization bypass risks
• Sensitive data exposure

Phase 6: Code Quality Metrics

Style & Conventions

• Credo compliance
• Formatter consistency
• Module organization
• Function complexity
• Documentation coverage

Architecture Patterns

• Context boundaries
• Dependency direction
• Interface segregation
• Error handling patterns

For common issues, load: references/common-issues.md
