SYSTEM DOCUMENTATION & REQUIREMENTS

## What problem does it solve? ShieldCode enforces non-negotiable security and error-handling rules that activate automatically whenever Claude generates code, preventing OWASP Top 10 vulnerabilities and enforcing secure defaults across JavaScript/TypeScript and Python.

## Core Features & Use Cases

  • Enforces input validation, safe authentication, parameterized queries, structured logging, timeouts with retries, and secure configuration.
  • Covers APIs, data processing scripts, and code that handles user input, databases, file operations, and logging with production-grade safety.

### Quick Start Prompt Claude to generate code with ShieldCode active to enforce security and error-handling rules.

FAQPage Schema
How do I prevent OWASP Top 10 vulnerabilities in AI-generated code?

To prevent OWASP Top 10 vulnerabilities in AI-generated code, enforce secure-by-default rules covering input validation, parameterized queries, and safe authentication across JavaScript, TypeScript, and Python.

How do I enforce secure authentication and input validation for API endpoints?

Enforce secure authentication and input validation for API endpoints by applying strict validation rules, parameterized database queries, and structured logging to prevent injection attacks and unauthorized access.

Can I use automated security rules with JavaScript, TypeScript, and Python?

Yes, automated security rules apply to JavaScript, TypeScript, and Python by enforcing strict validation, timeouts with retries, and secure configuration checks at startup across these languages.

What's the best way to secure data processing scripts and cloud functions?

The best way to secure data processing scripts and cloud functions is enforcing non-negotiable rules for file operations, structured logging, and error hierarchies to ensure production-grade safety.

Why does AI-generated code need strict error handling and secure configuration checks?

AI-generated code needs strict error handling and secure configuration checks to prevent runtime failures, enforce timeouts with retries, and ensure that startup configurations meet security standards automatically.
