Where does the skill store the generated documentation?

The skill creates a structured 'docs/' directory containing seven specific Markdown files ranging from system overviews to security and access control policies.

What kind of diagrams does this skill create?

It generates several types of Mermaid.js diagrams, including high-level system architecture, C4 context diagrams, deployment topologies, and business workflow flowcharts.

Can I use this for security audits?

The skill provides a specialized 'security-and-access.md' template to document authentication models, authorization roles, and data handling compliance requirements.

When is the best time to use the System Mapper?

It should be used after initial discovery phases, such as API exploration, script analysis, and entity relationship mapping, to synthesize that raw data into a readable format.

Does it document external service integrations?

Yes, it includes a dedicated integration map that details external providers, authentication methods, endpoints used, and data exchange patterns.

Learning & Documentation

Generates comprehensive system documentation and Mermaid architecture diagrams from discovered codebase and API metadata.

The System Architecture Mapper is a specialized tool for synthesizing technical discoveries into professional-grade documentation. By analyzing API schemas, script relationships, and entity data, it produces a structured suite of Markdown files including C4 context diagrams, data models, and integration maps. It is particularly valuable for developers and architects who need to create 'living documentation' that accurately reflects the current state of a complex system without the manual overhead of traditional diagramming tools.
