SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you write or review code with secure-by-default guidance tailored to the languages, frameworks, and stack type in your project, so security decisions are consistent instead of improvised.

Core Features & Use Cases

  • Language and framework scoping: Identifies the project’s languages, runtime, frameworks, and stack split so the right security guidance is applied.
  • Multiple operating modes: Supports proactive secure coding, passive detection during other work, and full reporting for broader audits.
  • Practical security defaults: Reinforces safe secrets handling, input validation, output encoding, authentication, cryptography, and redacted logging.
  • Use case: Ideal when starting a new service, adding an integration or auth flow, or reviewing an existing codebase for security weaknesses across frontend and backend paths.

Quick Start

Ask this Skill to review your project by listing the languages, frameworks, stack split, and data classification so it can apply the matching secure-by-default guidance.

Frequently Asked Questions about Secure Code by Language

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I perform a security audit on an existing codebase with multiple languages?▼

To perform a security audit, identify the project's languages, frameworks, stack split, and data classification. This enables applying matching secure-by-default guidance to enforce validated input, safe secret handling, and framework-default escaping across the codebase.

What is secure-by-default guidance for software development?▼

Secure-by-default guidance applies language- and framework-specific rules to ensure consistent security decisions. It enforces validated input, safe secret handling, framework-default escaping, and structured logging instead of improvised security measures.

Can I review frontend and backend code for OWASP vulnerabilities simultaneously?▼

Yes, you can review frontend and backend paths simultaneously by defining the stack split. The guidance enforces secure defaults, framework-default escaping, and validated input handling across the entire stack.

Does this secure coding guidance support CLI and library stacks?▼

Yes, the secure coding guidance explicitly supports CLI and library stacks alongside backend and frontend environments. It enforces language-specific input validation, safe secret handling, and structured logging across these runtime environments.

How do I apply secure defaults during a code refactor?▼

To apply secure defaults during a refactor, use the passive detection mode. It enforces framework-default escaping and redacted logging while detecting security weaknesses during your ongoing code modifications.

What is the best way to enforce safe secret handling across different frameworks?▼

The best way is to identify your project's frameworks and data classification first. This triggers framework-specific secure-by-default guidance that standardizes safe secret handling, cryptography, and authentication rules across the codebase.
