About
fr33d3m0n-threat-modeling is a Claude Code security plugin that packages an AI-native, code-first risk analysis skill for developers and small teams who must threat-model real software—not slideware—before customers touch it. The catalog describes a strict, sequential eight-phase workflow that forces alignment across project understanding, boundary definition, threat generation, mitigation planning, security testing, penetration testing, compliance checking, and final reporting. That structure suits SaaS and API products where one person owns architecture, implementation, and release checklists. Use it when you are shipping auth, payments, multi-tenant data, or external integrations and need STRIDE-grounded reasoning tied to your codebase rather than generic OWASP bullet lists. It is advanced in scope: expect to feed repository context and respect phase gates. It complements—not replaces—professional pentests and formal audits, but gives you repeatable artifacts and test intent you can hand to reviewers or your future self before launch.
- Mandatory sequential 8-phase workflow with strict phase alignment before outputs advance
- Code-first, LLM-driven threat modeling including STRIDE-style analysis and trust-boundary work
- Spans security testing and penetration-test planning—not only a one-page diagram
- Structured project outputs: understanding, design review, mitigation, validation, and reporting artifacts
- Single-plugin bundle aimed at automated software risk analysis rather than ad-hoc security chat

What it does
Install this plugin when you want an LLM-guided, code-first threat modeling workflow that walks from system understanding through STRIDE analysis, mitigations, security testing, and compliance-oriente
Who is it for?
Best when you're shipping SaaS or APIs and want repeatable STRIDE-oriented threat modeling and security-test planning without hiring a full-time AppSec team first.
Skip if: Skip if you only need a quick dependency scan or a single lint rule—this is a multi-phase security methodology, not a one-click scanner.
What you get
After registering the plugin, you can walk a gated eight-phase analysis that produces structured threat understanding, mitigations, security-test direction, and reporting suitable for pre-release review.
- Eight-phase security analysis artifacts from understanding through validation
- STRIDE-oriented threats, trust boundaries, and mitigation plans
- Security-test and penetration-test oriented guidance plus structured reporting outputs
