Review Checklist Skill

This skill generates targeted code review checklists customized for the specific programming language or files in your change.

When to Use

• Before submitting a PR for review
• When reviewing code from teammates
• To ensure consistency with language best practices
• To catch common language-specific pitfalls

Supported Languages

• TypeScript — Type safety, async/await patterns, React/Node conventions
• C# — Null safety, async patterns, LINQ, .NET framework usage
• C++ — Memory management, smart pointers, const correctness, thread safety
• Python — Type hints, exception handling, PEP 8, async patterns
• Go — Error handling, goroutines, channels, interfaces
• Java — NullPointerException handling, resource management, collection APIs

Checklist Categories

Each checklist includes checks for:

Type Safety

• Type annotations present and correct
• No unsafe casts or type assertions
• Proper generic type usage
• Runtime type validation where needed

Error Handling

• All exceptions/errors properly handled
• No silent failures or swallowed exceptions
• Appropriate error recovery strategies
• User-facing error messages are clear

Testing & Coverage

• Unit tests for new logic
• Edge cases covered
• Error paths tested
• Integration points validated

Security

• Input validation and sanitization
• No hardcoded credentials or secrets
• Proper authentication/authorization checks
• SQL injection and XSS prevention

Documentation

• Public API methods documented
• Complex logic has explanatory comments
• Breaking changes noted
• Examples provided for non-obvious behavior

Output Format

Checklists are formatted as markdown with categories as sections, each containing checkboxes:

## [Language] Code Review Checklist

Example Usage

/review-checklist TypeScript
/review-checklist C#
/review-checklist for src/auth.ts
/review-checklist Python

The skill automatically detects the language from file extensions when provided, or uses the language name directly to generate the appropriate checklist.
