SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Security failures in AI-assisted development happen not because the AI produces insecure code on purpose, but because vibe-coders do not ask for security in their prompts. This skill changes that: it exists to run an explicit security pass over every user-facing feature.

Core Features & Use Cases

Threat modeling and security hardening as a formal step before feature build.
JWT-based authentication, token rotation, and row-level authorization across FastAPI and Next.js.
Secure file upload validation, CORS controls, and security headers with production-ready defaults.

Quick Start

Implement a security hardening pass on a new feature by modeling threats, applying OWASP Top 10 checks, and enabling secure token handling for user data.

FAQPage Schema

How do I add JWT-based authentication and token rotation to a FastAPI backend?▼

JWT-based authentication with token rotation is implemented by running a security hardening pass that enforces secure token handling and row-level authorization across API endpoints for user data.

What is threat modeling in AI-assisted development and when do I need it?▼

Threat modeling is an explicit security pass applied before feature builds to identify and mitigate risks in AI-assisted development. It is needed when secure authentication and safe data handling are required.

How do I configure secure file uploads and CORS restrictions for Next.js frontends?▼

Secure file uploads and CORS restrictions are configured by applying validation controls and production-ready security headers across API endpoints and web interfaces during the security review process.

Does this security review apply OWASP Top 10 checks to FastAPI and Next.js stacks?▼

Yes, the security review applies OWASP Top 10 checks across FastAPI backends and Next.js frontends, covering user authentication, authorization, and secure file uploads for production-ready defaults.

What's the best way to enforce row-level authorization and secret management in production?▼

The best way to enforce row-level authorization and secret management is running an end-to-end security review that establishes production-ready defaults for token handling and access controls.
