code-review

When this skill is invoked:

1. Read the target file(s) in full.

2. Read the CLAUDE.md for project coding standards.

3. Identify the system category (engine, gameplay, AI, networking, UI, tools) and apply category-specific standards.

4. Evaluate against coding standards:

   • Public methods and classes have doc comments
   • Cyclomatic complexity under 10 per method
   • No method exceeds 40 lines (excluding data declarations)
   • Dependencies are injected (no static singletons for game state)
   • Configuration values loaded from data files
   • Systems expose interfaces (not concrete class dependencies)

5. Check architectural compliance:

   • Correct dependency direction (engine <- gameplay, not reverse)
   • No circular dependencies between modules
   • Proper layer separation (UI does not own game state)
   • Events/signals used for cross-system communication
   • Consistent with established patterns in the codebase

6. Check SOLID compliance:

   • Single Responsibility: Each class has one reason to change
   • Open/Closed: Extendable without modification
   • Liskov Substitution: Subtypes substitutable for base types
   • Interface Segregation: No fat interfaces
   • Dependency Inversion: Depends on abstractions, not concretions

7. Check for common game development issues:

   • Frame-rate independence (delta time usage)
   • No allocations in hot paths (update loops)
   • Proper null/empty state handling
   • Thread safety where required
   • Resource cleanup (no leaks)

8. Output the review in this format:
