SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This skill helps teams perform evidence-first adversarial security audits to identify reproducible vulnerabilities across agent systems, financial programs, and software applications, while delivering prioritized risk findings without applying patches.

Core Features & Use Cases

  • Modular workflow with modules: agent-system, financial-program, software-system, and combined usage.
  • Deterministic attack scenarios that yield concrete evidence and repeatable results.
  • Reporting-first output with prioritized risks, impact, and hardening guidance without code remediation.
  • Explicit discovery-only boundaries to prevent unintended remediation actions.

Quick Start

Run a discovery-only audit using the module catalog to surface reproducible vulnerabilities with evidence and prioritized hardening guidance.

FAQPage Schema
How do I perform an evidence-first security audit without modifying my application code?

An evidence-first security audit identifies reproducible vulnerabilities using deterministic attack scenarios and returns prioritized risk findings without applying remediation. It operates in a discovery-only mode to prevent unintended code patches while surfacing concrete path:line evidence.

Can I run a security vulnerability audit across both agent systems and financial programs?

Yes, you can run a security vulnerability audit across agent systems, financial programs, and software applications. The audit uses a modular workflow with specialized modules to identify vulnerabilities and deliver prioritized hardening guidance tailored to each system type.

What is a deterministic attack scenario in a security audit?

A deterministic attack scenario in a security audit is a testing method that yields concrete, repeatable evidence of vulnerabilities. It ensures consistent results by surfacing reproducible flaws and returning findings with path:line evidence and impact rankings.

Does this security audit provide code remediation for discovered vulnerabilities?

No, this security audit does not provide code remediation. It operates within explicit discovery-only boundaries, returning prioritized risk reports, impact rankings, and hardening guidance to inform your team's remediation strategies without directly patching the code.

How do I get started with a discovery-only audit for my software system?

To get started with a discovery-only audit, select the appropriate module from the catalog to surface reproducible vulnerabilities. The audit will return concrete evidence, impact rankings, and hardening guidance without executing any remediation actions.
