Can I use this for existing legacy codebases?

Yes, the skill can help you decompose existing architectures into Data Flow Diagrams to identify legacy vulnerabilities and missing trust boundaries.

What security methodologies does this threat-modeling skill support?

The skill primarily supports STRIDE (Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, Elevation of Privilege) and DREAD (Damage, Reproducibility, Exploitability, Affected users, Discoverability) frameworks.

Does this skill provide automated security fixes?

While it focuses on identification and design-level mitigation, it suggests specific implementation patterns and countermeasures to address identified threats.

How does 'threat modeling as code' work with Claude Code?

It allows you to define your system architecture programmatically using C# or other schemas, enabling Claude to automate threat identification and keep security docs in sync with code.

安全与测试

Conducts systematic security assessments using STRIDE and DREAD methodologies to identify and mitigate software vulnerabilities during design.

This skill empowers developers to integrate proactive security into their software development lifecycle (SDLC) by automating the threat modeling process. It guides users through system decomposition using Data Flow Diagrams (DFDs), applies industry-standard frameworks like STRIDE for threat identification, and utilizes DREAD for risk prioritization. By transforming threat modeling into an actionable, code-centric activity, it helps teams document security assumptions, visualize attack surfaces, and implement robust countermeasures before a single line of production code is written.
