What problem does it solve? Individual vulnerability patches often leave the underlying structural weaknesses untouched, so the same class of flaw recurs. This Skill turns scan findings, vulnerability disclosures, incident reports, or source code into a decision-ready portfolio of structural and architectural hardening proposals with real options, tradeoffs, and migration plans. ## Core Features & Use Cases - Evidence-driven opportunity analysis: Clusters findings by violated invariant, trust boundary, and control ownership to identify high-leverage hardening opportunities, or honestly concludes that local remediation is preferable. - Multi-option design proposals: Produces per-opportunity proposals with before-and-after Mermaid diagrams, delta tables, and tradeoff analysis across security, performance, memory, reliability, operability, and migration dimensions. - Structured artifacts: Emits a machine-readable hardening.json, a skimmable hardening.md portfolio, per-opportunity proposal documents, and implementation work packages once an option is selected. - Use Case: After a security scan of an archive extraction module reveals several path traversal findings, use this Skill to evaluate whether to patch each call site, centralize containment behind one owned boundary, or introduce process isolation, complete with diagrams and a conditional recommendation. ## Quick Start Analyze the findings from my latest security scan and propose architectural hardening options with tradeoffs and diagrams.
