What problem does it solve? Security testing is often fragmented across tools and standards, making it hard to systematically cover OWASP vulnerability classes, map findings to compliance frameworks, and trace tests back to identified threats. This Skill provides a unified four-phase workflow (threat model, security plan, test execution, security report) covering all four OWASP domains. ## Core Features & Use Cases - Full OWASP Coverage: Test patterns for 40 vulnerability classes across Web Top 10 (A01-A10), API Top 10 (API01-API10), Mobile Top 10 (M1-M10), and LLM Top 10 (LLM01-LLM10). - Threat-Driven Planning: Build a threat register with STRIDE or risk-based modeling, then map every test case to a threat ID and OWASP class for full traceability. - Compliance Mapping: Link test results to ISO 27001, PCI-DSS, HIPAA, and SOC2 requirements, producing audit-ready security and compliance reports. - Use Case: Audit a REST API against the OWASP API Top 10 by generating @atc-decorated tests for BOLA, broken authentication, rate limiting, and SSRF, then produce a remediation backlog ranked by severity. ## Quick Start Ask the AI to run a security assessment of your web application against the OWASP Top 10, starting with a threat model and ending with a compliance-mapped findings report.
