File Analysis Tool

Perform comprehensive analysis of $ARGUMENTS to identify code quality issues, security vulnerabilities, and optimization opportunities.

Task

I'll analyze the specified file and provide detailed insights on:

1. Code quality metrics and maintainability
2. Security vulnerabilities and best practices
3. Performance bottlenecks and optimization opportunities
4. Dependency usage and potential issues
5. TypeScript/JavaScript specific patterns and improvements
6. Test coverage and missing tests

Process

I'll follow these steps:

1. Read and parse the target file
2. Analyze code structure and complexity
3. Check for security vulnerabilities and anti-patterns
4. Evaluate performance implications
5. Review dependency usage and imports
6. Provide actionable recommendations for improvement

Analysis Areas

Code Quality

• Cyclomatic complexity and maintainability metrics
• Code duplication and refactoring opportunities
• Naming conventions and code organization
• TypeScript type safety and best practices

Security Assessment

• Input validation and sanitization
• Authentication and authorization patterns
• Sensitive data exposure risks
• Common vulnerability patterns (XSS, injection, etc.)

Performance Review

• Bundle size impact and optimization opportunities
• Runtime performance bottlenecks
• Memory usage patterns
• Lazy loading and code splitting opportunities

Best Practices

• Framework-specific patterns (React, Vue, Angular)
• Modern JavaScript/TypeScript features usage
• Error handling and logging practices
• Testing patterns and coverage gaps

I'll provide specific, actionable recommendations tailored to your project's technology stack and architecture.
