Review all changed or newly added code in this repository for code style and quality issues. Check both staged and unstaged changes.
Rules
Naming & Structure
- Meaningful, consistent names — same concept = same name throughout. Variable names should be pronounceable and searchable.
- Single Responsibility — each module/function has one reason to change.
- Depend on abstractions — use DI tags and interfaces, not concrete implementations directly.
Code Quality
- No duplicated code — similar code in multiple locations with the same calling context should be extracted.
- Avoid deep nesting — max 3 levels of conditional nesting. Refactor with early returns or extraction.
- Short parameter lists — more than 3-4 parameters suggests the need for an options object or restructuring.
- Self-documenting code — comment only what the code cannot express through naming and structure. Remove comments that repeat what the code already says.
Cleanup
- No dead code — remove unused variables, functions, imports, and commented-out code blocks.
- Fix typos — in variable names, comments, and strings.
SOLID Principles
- Single Responsibility: One responsibility to one actor
- Open/Closed: Open for extension, closed for modification
- Liskov Substitution: Subtypes must be substitutable
- Interface Segregation: No forced implementation of unused methods
- Dependency Inversion: Depend on abstractions, not concretions
Design Patterns (GoF)
- Creational Patterns: Factory, Abstract Factory, Builder, Prototype, Singleton
- Structural Patterns: Adapter, Bridge, Composite, Decorator, Facade, Flyweight, Proxy
- Behavioral Patterns: Observer, Strategy, Command, State, Template Method, Chain of Responsibility
Output Format
For each issue found, output:
- File: path and line number
- Rule: which rule is violated
- Problem: what the code does wrong
- Fix: how to correct it
If no issues are found, confirm the code is clean.
