💡 This Skill includes scripts (resource) and references (resource) and examples (resource) and templates (resource) components.

What problem does it solve?

This Skill provides a systematic methodology to deeply understand unfamiliar codebases, enabling efficient security audits and vulnerability analysis by mapping architecture, data flows, and critical components.

Core Features & Use Cases

  • Architecture Mapping: Visualize system structure, components, and trust boundaries.
  • Data Flow Tracing: Track data movement through the application.
  • Critical Function Identification: Pinpoint security-sensitive code sections.
  • Use Case: When starting a security audit on a new project, use this Skill to quickly build a comprehensive understanding of its architecture, identify key modules, and pinpoint potential areas of risk before diving into detailed code review.

Quick Start

Use the code-recon skill to generate an architecture diagram for the provided codebase.

FAQPage Schema
How do I map an unfamiliar codebase for a security audit?

To map an unfamiliar codebase for a security audit, systematically analyze the system structure, trace data flows, define trust boundaries, and pinpoint security-sensitive critical functions using a phased reconnaissance approach.

What is data flow tracing in vulnerability assessment?

Data flow tracing in vulnerability assessment tracks data movement through an application to identify how inputs traverse system modules. This process highlights security-sensitive code sections and potential risk areas before detailed code review.

How do I identify critical functions and trust boundaries in source code?

Identify critical functions and trust boundaries in source code by visualizing the system architecture and tracking data movement. This architectural mapping highlights modules handling sensitive operations and separates trusted components from untrusted inputs.

Can I use architecture mapping to prepare for vulnerability analysis on any codebase?

Yes, architecture mapping supports vulnerability analysis on any codebase by systematically building deep architectural context. It maps system structure and components to pinpoint potential areas of risk efficiently.

What is the best way to start reconnaissance on a new codebase for security reviews?

The best way to start reconnaissance for security reviews is generating an architecture diagram. This visualizes system structure, maps data flows, and identifies critical components to build comprehensive project understanding quickly.

Why does code analysis fail to find vulnerabilities without architecture mapping?

Code analysis fails to find vulnerabilities without architecture mapping because it lacks deep architectural context. Without tracing data flows and trust boundaries, security reviews miss critical functions and systemic risk areas across unfamiliar modules.
