Tasks Code Review

Skill Variant: Use this skill for autonomous, comprehensive code reviews with structured checklists. For interactive code review discussions with user feedback, use code-review instead.

Code Review Workflow

Summary

Goal: Perform autonomous, comprehensive code reviews with structured checklists covering architecture, patterns, quality, security, and performance.

Key Principles:

• Autonomous variant — for interactive reviews with user feedback, use code-review instead
• Check all 5 review dimensions: architecture, patterns, quality, security, performance
• Every finding must reference specific file and line

When to Use This Skill

• Reviewing pull requests
• Analyzing code for refactoring
• Pre-commit code quality check
• Security and performance audit

Review Dimensions

1. Architecture Compliance

• Follows Clean Architecture layers
• Uses correct repository pattern
• No cross-service boundary violations
• Proper separation of concerns

2. Pattern Adherence

• CQRS patterns followed (Command/Query/Handler in ONE file)
• Entity patterns correct (expressions, computed properties)
• Frontend component hierarchy respected
• Platform base classes used correctly

3. Code Quality

• Single Responsibility Principle
• No code duplication
• Meaningful naming
• Appropriate abstractions

4. Security

• No SQL injection vulnerabilities
• Authorization checks present
• Sensitive data handling
• Input validation

5. Performance

• N+1 query prevention (eager loading)
• Proper paging for large datasets
• Parallel operations where applicable
• Caching considerations

Review Process

Step 1: Understand Context

# Get changed files
git diff --name-only main...HEAD

# Get full diff
git diff main...HEAD

# Check commit messages
git log main...HEAD --oneline

Step 2: Categorize Changes

## Files Changed

### Domain Layer
- `Entity.cs` - New entity

### Application Layer
- `SaveEntityCommand.cs` - New command

### Persistence Layer
- `EntityConfiguration.cs` - EF configuration

### Frontend
- `entity-list.component.ts` - List component

Step 3: Review Each Category

Backend Review Checklist

## Entity Review
- [ ] Inherits from correct base (RootEntity/RootAuditedEntity)
- [ ] Static expressions for queries
- [ ] Computed properties have empty `set { }`
- [ ] Navigation properties have `[JsonIgnore]`
- [ ] `[TrackFieldUpdatedDomainEvent]` on tracked fields

## Command/Query Review
- [ ] Command + Handler + Result in ONE file
- [ ] Uses service-specific repository
- [ ] Validation uses fluent API
- [ ] No side effects in command handler
- [ ] DTO mapping in DTO class, not handler

## Repository Usage Review
- [ ] Uses `GetQueryBuilder` for reusable queries
- [ ] Uses `WhereIf` for optional filters
- [ ] Parallel tuple queries for count + data
- [ ] Proper eager loading

## Event Handler Review
- [ ] In `UseCaseEvents/` folder
- [ ] Uses `PlatformCqrsEntityEventApplicationHandler<T>`
- [ ] `HandleWhen` is `public override async Task<bool>`
- [ ] Filters by `CrudAction` appropriately

Frontend Review Checklist

## Component Review
- [ ] Correct base class for use case
- [ ] Store provided at component level
- [ ] Loading/error states handled
- [ ] `untilDestroyed()` on subscriptions
- [ ] Track-by in `@for` loops

## Store Review
- [ ] State interface defined
- [ ] `vmConstructor` provides defaults
- [ ] Effects use `observerLoadingErrorState`
- [ ] Immutable state updates

## Form Review
- [ ] `validateForm()` before submit
- [ ] Async validators conditional
- [ ] Dependent validations configured
- [ ] Error messages for all rules

## API Service Review
- [ ] Extends `PlatformApiService`
- [ ] Typed responses
- [ ] Caching where appropriate

Step 4: Security Review

## Security Checklist

### Authorization
- [ ] `[PlatformAuthorize]` on controllers
- [ ] Role checks in handlers
- [ ] Data filtered by company/user context

### Input Validation
- [ ] All inputs validated
- [ ] No raw SQL strings
- [ ] File upload validation

### Sensitive Data
- [ ] No secrets in code
- [ ] Passwords hashed
- [ ] PII handled correctly

Step 5: Performance Review

## Performance Checklist

### Database
- [ ] Indexes on filtered columns
- [ ] Eager loading for N+1 prevention
- [ ] Paging for large datasets

### API
- [ ] Response size reasonable
- [ ] Parallel operations used
- [ ] Caching for static data

### Frontend
- [ ] Lazy loading for routes
- [ ] Track-by for lists
- [ ] OnPush change detection
