What problem does it solve?

This Skill helps engineers identify and remediate security weaknesses early in the development process, turning security from an afterthought into a systematic practice.

Core Features & Use Cases

  • OWASP Top 10 guidance applied to authentication, authorization, input validation, data exposure, and configuration issues.
  • Checklist-driven reviews that Junior developers can follow to verify secure handling of secrets, tokens, and user data.
  • Practical examples showing how to harden login flows, protect APIs, and validate inputs.

Quick Start

Activate this skill during code reviews of authentication or data-handling logic. Run the security fundamentals review against the project, iterating on any identified risks and aligning with OWASP guidance.
