Code Review: $ARGUMENTS

Perform a comprehensive code review following EasyPlatform standards.

Summary

Goal: Comprehensive report-driven code review of a PR, file, or branch following EasyPlatform standards.

Step	Action	Key Notes
1	Create report file	plans/reports/code-review-{date}-{slug}.md
2	File-by-file review	Read each file, update report with summary/purpose/issues
3	Holistic review	Re-read report for architecture coherence and layer correctness
4	Final findings	Critical issues, high priority, architecture recommendations

Key Principles:

• Build report incrementally -- update after EACH file review
• Check: architecture compliance, naming, platform patterns, security, performance
• Logic must be in the LOWEST appropriate layer (Entity > Service > Component)
• Holistic phase: ask "For each architectural decision, WHY this approach over alternatives? Are there trade-offs to document?"

Review Scope

Target: $ARGUMENTS (can be a PR number, file path, or branch name)

Review Approach (Report-Driven Two-Phase - CRITICAL)

⛔ MANDATORY FIRST: Create Todo Tasks for Review Phases Before starting, call TodoWrite with:

• [Review Phase 1] Create report file - in_progress
• [Review Phase 1] Review file-by-file and update report - pending
• [Review Phase 2] Re-read report for holistic assessment - pending
• [Review Phase 3] Generate final review findings - pending Update todo status as each phase completes. This ensures review is tracked.

Step 0: Create Report File

• Create plans/reports/code-review-{date}-{slug}.md
• Initialize with Scope, Files to Review sections

Phase 1: File-by-File Review (Build Report Incrementally) For EACH file, read and immediately update report with:

• File path
• Change Summary: what was modified/added
• Purpose: why this change exists
• Issues Found: naming, typing, responsibility, patterns
• Continue to next file, repeat

Phase 2: Holistic Review (Review the Accumulated Report) After ALL files reviewed, re-read the report to see big picture:

• Overall technical approach makes sense?
• Solution architecture coherent as unified plan?
• New files in correct layers (Domain/Application/Presentation)?
• Logic in LOWEST appropriate layer?
• Backend: mapping in Command/DTO (not Handler)?
• Frontend: constants/columns in Model (not Component)?
• No duplicated logic across changes?
• Service boundaries respected?
• No circular dependencies?

Phase 3: Generate Final Review Result Update report with final sections:

• Overall Assessment (big picture summary)
• Critical Issues (must fix before merge)
• High Priority (should fix)
• Architecture Recommendations
• Positive Observations

Review Checklist

1. Architecture Compliance

• Follows Clean Architecture layers (Domain, Application, Persistence, Service)
• Uses correct repository pattern (I{Service}RootRepository)
• CQRS pattern: Command/Query + Handler + Result in ONE file
• No cross-service direct database access

2. Code Quality

• Single Responsibility Principle
• No code duplication (DRY)
• Appropriate error handling with PlatformValidationResult
• No magic numbers/strings (extract to named constants)
• Type annotations on all functions
• No implicit any types
• Early returns/guard clauses used

2.5. Naming Conventions

• Names reveal intent (WHAT not HOW)
• Specific names, not generic (employeeRecords not data)
• Methods: Verb + Noun (getEmployee, validateInput)
• Booleans: is/has/can/should prefix (isActive, hasPermission)
• No cryptic abbreviations (employeeCount not empCnt)

3. Platform Patterns

• Uses platform validation fluent API (.And(), .AndAsync())
• No direct side effects in command handlers (use entity events)
• DTO mapping in DTO classes, not handlers
• Static expressions for entity queries

4. Security

• No hardcoded credentials
• Proper authorization checks
• Input validation at boundaries
• No SQL injection risks

5. Performance

• No O(n²) complexity (use dictionary for lookups)
• No N+1 query patterns (batch load related entities)
• Project only needed properties (don't load all then select one)
• Pagination for all list queries (never get all without paging)
• Parallel queries for independent operations
• Appropriate use of async/await

Output Format

IMPORTANT Task Planning Notes

• Always plan and break many small todo tasks
• Always add a final review todo task to review the works done at the end to find any fix or enhancement needed
