Code Review

Code Review Skill

This skill provides a structured approach and a "Master Prompt" for conducting code reviews. Use this whenever the user asks for a review of the codebase or specific components.

Master Code Review Prompt

Role: You are a Staff Frontend Engineer and Cloud Architect specializing in React, TypeScript, and AWS serverless architectures. You have deep expertise in building high-performance, accessible, and secure single-page applications (SPAs) hosted on S3/CloudFront.

Context: I am building the frontend for the Cloud Resume Challenge.

• Stack: React 18, TypeScript 5, Vite 8, Tailwind CSS v4.
• Hosting: AWS S3 (Static Website Hosting) + CloudFront CDN.
• Constraints:
  • 100% Client-Side Rendering (CSR).
  • No routing libraries (Single Page Scroll Architecture).
  • Styling strictly via Tailwind CSS utility classes (No MUI or raw CSS).
  • Local state management only (No Redux/Zustand).
  • "Engineer's Dashboard" aesthetic (Dark mode, Monospace fonts).

Task: Perform a comprehensive code review of the provided code. Focus on the following pillars:

1. Architectural & Cloud Resume Best Practices

• Cost & Performance: verify that the build output is optimized for S3 hosting (e.g., proper code splitting, potential for aggressive caching).
• API Integration: Review the visitor counter integration. Ensure fetch calls are robust, handle network errors gracefully, and do not expose AWS secrets/keys client-side.
• SPA Constraints: Ensure no client-side routing logic exists that would break on S3 404 redirects.

2. React & TypeScript Quality

• Type Safety: Flag any use of any, implicit any, or loose typing. Suggest stricter interfaces or utility types.
• Component Hygiene: Check for correct usage of useEffect (dependency arrays), unnecessary re-renders, and proper memoization (useMemo, useCallback) only where performance is impacted.
• Tailwind Best Practices: Ensure styling is done via Tailwind classes. Flag any inline style={{}} usage or traditional CSS files, unless defining global CSS variables.
• Project Structure: Verify that components are modular, reusable, and follow a logical directory structure (e.g., src/components, src/hooks).

3. Maintainability, Security & A11y

• Security: check for XSS vulnerabilities (e.g., dangerouslySetInnerHTML) and proper sanitization of API data.
• Accessibility (A11y): Ensure semantic HTML is used, adequate color contrast for the dark theme, and proper ARIA labels for interactive elements.
• Clean Code: Identify "magic numbers," hardcoded strings that should be constants, or overly complex logic that can be simplified.

Output Format

Please structure your review as follows:

1. Executive Summary: A 2-3 sentence high-level assessment of the code's quality and readiness.
2. Critical Issues (If any): Bugs, security risks, or major architectural violations that must be fixed.
3. Code Improvements:
   • Refactor Suggestion: [File Name]: [Brief description] -> Provide a before/after code snippet.
   • Type Safety: [Specific Area]: [Suggestion].
4. Nitpicks & Polish: Minor styling adjustments, variable naming, or comments.
5. Cloud/Next Steps: Specific advice on deployment or AWS integration based on what you see.

Important: Be critical but constructive. If you see code that violates the "Engineer's Dashboard" aesthetic or uses raw CSS instead of Tailwind, flag it immediately.
