What this skill does
Engineering Fundamentals Review "Code is read more than it is written. Write for the reader, not the machine." When to Apply Activate this skill when reviewing: Any code changes Function and variable naming Code organization and structure General refactoring decisions --- Review Checklist Naming [ ] Descriptive: Can you understand the variable without context? [ ] No abbreviations: Are names spelled out? (user not usr) [ ] No generic names: No data, temp, info, stuff? [ ] Boolean prefix: Do booleans start with is, has, can, should? [ ] Function verbs: Do functions start with action verbs? Function Design [ ] Single responsibility: Does each function do ONE thing? [ ] Size limit: Are functions under 20-30 lines? [ ] Parameter count: Are there fewer than 4 parameters? [ ] No side effects: Are pure functions actually pure? [ ] Early returns: Are guard clauses used instead of deep nesting? Code Organization [ ] DRY: Is duplicated code extracted into functions? [ ] But not too DRY: Are abstractions justified (rule of three)? [ ] Cohesion: Are related things grouped together? [ ] Separation: Are unrelated things separated? Comments & Documentation [ ] Why, not what: Do comments explain reasoning, not obvious code? [ ] No commented-out code: Is dead code deleted, not commented? [ ] JSDoc on public APIs: Are exported functions documented? --- Common Mistakes (Anti-Patterns) 1. Magic Numbers 2. Unclear Naming 3. God Functions 4. Deep Nesting 5. …
