SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill guides learners through structured threat reasoning to understand how to think about code security, rather than simply catalog vulnerabilities.

Core Features & Use Cases

  • Gated threat reasoning process: Enforces human-required gates at each phase to ensure active learner engagement.
  • Socratic prompts: Provides disciplined questions that guide threat discovery without giving away vulnerabilities.
  • Artefact capture: Captures threat models, assumptions, attack scenarios, and defense rationales for learning journals.
  • Safe boundaries: Keeps focus on reasoning processes rather than auditing or patching code.

Quick Start

Initiate a session with a short code example, then progress through the eight phases to practice adversarial thinking and threat modeling.

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

FAQPage Schema
How do I learn threat modeling for code security instead of just memorizing vulnerabilities?▼

Threat modeling teaches you to reason about code security by identifying threat actors, trust boundaries, and defenses through structured, gated phases rather than cataloging known vulnerabilities.

What is the best way to practice adversarial thinking during code review?▼

Adversarial thinking during code review is practiced by applying Socratic prompts to discover threats, capture attack scenarios, and document defense rationales without directly patching the code.

Can I use this threat reasoning process for analyzing API endpoints and learning projects?▼

Yes, structured threat reasoning applies directly to API endpoints and learning projects, guiding you to map trust boundaries and reason about defenses for those specific contexts.

Do I need prior security auditing experience to start structured threat reasoning?▼

No prior auditing experience is needed, as the process enforces human-required phase gates with Socratic prompts to guide threat discovery while focusing on reasoning rather than patching code.

What artefacts are captured during the gated threat reasoning phases?▼

The gated phases capture threat models, assumptions, attack scenarios, and defense rationales as artefacts, which are recorded specifically for learning accountability and journals.
