Overview

This skill provides a systematic approach to code reviews. It offers comprehensive checklist items across multiple dimensions of code quality, helps reviewers focus on high-impact areas, and guides developers in preparing code for review. Designed to make code reviews more efficient and thorough.

When to Use This Skill

• Preparing code for pull request review
• Conducting a code review as a reviewer
• Self-reviewing own code before submission
• Establishing code review standards for a team
• Training new developers on review best practices
• Auditing code quality in a codebase

What This Skill Provides

1. Predefined Checklists

Comprehensive checklist items organized by category:

• Code correctness and logic
• Code style and readability
• Performance and efficiency
• Security considerations
• Error handling
• Testing coverage
• Documentation
• Architecture and design patterns

2. Review Guidance

• What to look for in each category
• Red flags and common issues
• Best practices specific to language/framework
• Questions to ask the author

3. Review Workflow

• Systematic approach to reviewing
• Priority ordering of checks
• Time allocation guidance
• Documentation requirements

Language-Specific Considerations

JavaScript/TypeScript

• Proper async/await usage
• TypeScript types are correct
• No 'any' type abuse
• ESLint rules followed

Python

• PEP 8 compliance
• Type hints where appropriate
• Docstrings for public functions
• No deprecated imports

Java

• Null safety considerations
• Resource management (try-with-resources)
• Stream API usage
• Concurrent access considerations

Go

• Error handling conventions
• Goroutine leak prevention
• Context usage
• Naming conventions

Review Workflow

Step 1: Context (2-3 min)

• Read PR description and motivation
• Understand what changed and why
• Check related issues or docs

Step 2: Overview (3-5 min)

• Scan changed files
• Identify high-risk areas
• Note files needing deep review

Step 3: Detailed Review (15-30 min)

• Follow checklist by priority
• Comment on issues found
• Ask clarifying questions
• Suggest improvements

Step 4: Summary (3-5 min)

• Summarize findings
• Categorize issues (Blocking/Suggestion/Question)
• Approve or request changes

Usage Examples

As a Reviewer

"用程式碼審查清單檢查這個PR"
"幫我審查這個函式的邏輯"
"檢查這段程式碼有沒有安全問題"
"看看這個檔案有哪些可以改進的地方"

As a Developer

"幫我準備程式碼審查"
"自審查這份程式碼,有什麼遺漏?"
"檢查這段程式碼的測試覆蓋"
"這個程式碼符合專案規範嗎?"

For Team Standards

"生成一個程式碼審查檢查清單"
"我們團隊的程式碼審查標準是什麼?"
"前端程式碼審查有什麼特殊要求?"
