Description

Systematic code review checklist for Java projects. Covers null safety, exception handling, collections, concurrency, idioms, resource management, API design, and performance.

Use Cases

  • "Review this class"
  • "Check this PR for issues"

  • "What's wrong with this code?"

Examples

> view .claude/skills/java-code-review/SKILL.md
> "Review the changes in src/main/java/org/example/UserService.java"
→ Returns findings grouped by severity (Critical → Minor)

Checklist Categories

  1. Null Safety - NPE risks, Optional usage
  2. Exception Handling - Swallowed exceptions, stack traces
  3. Collections & Streams - Iteration, mutability
  4. Concurrency - Thread safety, race conditions
  5. Java Idioms - equals/hashCode, builders
