When asked to review or write code, apply this rigorous checklist: ## 1. Architectural Integrity - **SOLID Principles**: Are Single Responsibility, Open/Closed, etc., respected? - **Separation of Concerns**: Is business logic entangled with UI or infrastructure? - **Design Patterns**: Are patterns used correctly (e.g., Factory, Strategy), or is there over-engineering? ## 2. Code Cleanliness (Clean Code) - **Naming**: Do names reveal intent? Avoid `data`, `info`, `manager` unless specific. - **Functions**: Are they small? Do they do one thing? Is the cyclomatic complexity low? - **Comments**: Do comments explain *why*, not *what*? Delete commented-out code. - **DRY (Don't Repeat Yourself)**: Is logic duplicated? Can it be extracted? ## 3. Performance & Efficiency - **Complexity**: Watch for O(n^2) or worse algorithms in hot paths. - **IO**: Are database queries or API calls performed in loops (N+1 problem)? - **Memory**: Are large objects copied unnecessarily? ## 4. Error Handling & Edge Cases - **Failure Modes**: Does the code handle network failures, nulls, or empty states? - **User Feedback**: Are errors propagated meaningfully to the user/logs? ## 5. Testability - **Coverage**: Is the new logic covered by tests? - **Isolation**: Can the code be tested without mocking the entire universe? --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/pplmx) — claim your Tome and manage your conversions.
