Learning & Documentation

Generates comprehensive domain understanding documentation by analyzing codebases to extract entities, business logic, and conceptual relationships.

This skill automates the complex task of reverse-engineering business logic and domain structures from existing code. By scanning source files, it identifies core entities, data models, and service layers to construct a structured overview of a project's domain. It is particularly useful for onboarding new developers, auditing legacy systems, or synchronizing technical implementation with business requirements through automated glossary generation and Mermaid ER diagrams. The skill supports multiple languages and frameworks, providing a standardized bridge between code and conceptual design.
