What is a repository-grounded threat model?

It is a security analysis specifically based on the actual code, components, and architecture found in your repository, rather than a generic security checklist.

What kind of output does it generate?

It produces a comprehensive Markdown report containing the system model, trust boundaries, prioritized threats, and specific mitigation strategies tailored to your code.

How does it prioritize security risks?

It uses qualitative assessments of likelihood and impact (ranging from Low to Critical) based on attacker exposure and the sensitivity of the involved assets.

Does this skill perform general code reviews?

No, it is specifically designed for threat modeling and should not be used for general architecture summaries, linting, or non-security related design work.

When should I trigger this skill?

Use it when you need to perform an AppSec review, identify potential abuse paths, or document the security posture of a specific project path or codebase.

Seguridad y Pruebas

Generates repository-grounded AppSec threat models by analyzing trust boundaries, assets, and potential abuse paths.

This skill transforms Claude into a specialized application security engineer capable of producing professional-grade threat models directly from your source code. By analyzing your repository's architecture, entry points, and data flows, it enumerates realistic attacker goals, identifies critical trust boundaries, and suggests actionable mitigations. It follows a rigorous workflow that includes calibrating attacker capabilities and prioritizing risks based on qualitative likelihood and impact, ensuring the resulting Markdown report is grounded in evidence rather than generic security checklists.
