What problem does it solve?

JWT implementations are error-prone and can enable token forgery, insecure storage, and missing validations. This Skill detects common JWT flaws across codebases and helps teams harden their authentication flows.

Core Features & Use Cases

  • Detect algorithm confusion (alg:none), weak signing secrets, and missing exp/aud/iss validation across languages.
  • Flag insecure storage of tokens in localStorage or sessionStorage and suggest secure alternatives.
  • Provide actionable remediation guidance and example fixes for real-world projects.

Quick Start

Ask me to scan your codebase for JWT implementation flaws and propose concrete fixes.
