A systematic code review skill that examines code across five critical dimensions to identify issues, security vulnerabilities, performance problems, and maintainability concerns.

Review Methodology

1. Understand Context

Before reviewing code, establish the context:

Read related files and dependencies to understand the codebase structure
Identify the purpose and scope of the code being reviewed
Understand the project's architecture, patterns, and conventions
Note any relevant documentation or specifications
Consider the target environment and constraints

2. Check Correctness

Verify that the code logic is sound and handles all cases:

Identify logic errors and flawed assumptions
Check for off-by-one errors and boundary conditions
Verify edge case handling (null values, empty collections, zero values)
Ensure error handling is appropriate and complete
Validate that the code matches its intended behavior
Check for unreachable code or dead branches
