pasta-decompose

What problem does it solve?

This Skill addresses the complexity of understanding application architecture by systematically breaking it down into components, mapping trust boundaries, and classifying data sensitivity, which is crucial for effective threat modeling.

Core Features & Use Cases

• Application Decomposition: Identifies and inventories all functional units within an application.
• Trust Boundary Mapping: Visualizes where security perimeters exist between components and services.
• Data Classification: Assigns sensitivity levels (Public, Internal, Confidential, Restricted) to data entities.
• Role & Permission Analysis: Catalogs user roles and their associated permissions across components.
• Use Case: When performing a PASTA threat model, use this skill in Stage 3 to get a clear picture of your application's structure, data flow, and security posture before identifying specific threats.

Quick Start

Use the pasta-decompose skill to decompose the application and map trust boundaries with standard depth.
