Can it generate visual diagrams for my documentation?

Absolutely. It generates Mermaid diagrams for ERDs, service dependencies, authentication flows, and deployment architectures that can be rendered in GitHub or other Markdown viewers.

Which frameworks is this skill optimized for?

It is optimized for the Grey Haven tech stack, which primarily includes TanStack Start (frontend) with Drizzle ORM and FastAPI (backend) with SQLModel.

What is ontological documentation in the context of this skill?

It is a systematic way of mapping out the fundamental concepts, entities, and relationships within a Grey Haven codebase to create a clear, documented domain model.

Does this skill support multi-tenant architectures?

Yes, it is specifically designed to detect and document tenant_id isolation patterns, RLS roles, and tenant-scoped repository filters.

Aprendizaje y Documentación

Generates comprehensive ontological documentation and semantic maps to visualize and document Grey Haven’s domain models and system architectures.

Acerca de

This skill empowers Claude to analyze Grey Haven's multi-tenant codebases, specifically those built with TanStack Start and FastAPI, to extract and organize fundamental business concepts. By identifying core architectural patterns—such as tenant-id isolation, the repository pattern, and service-layer logic—it creates structured documentation and visual Mermaid diagrams. It is an essential tool for developers needing to onboard quickly, design complex new features with domain-driven principles, or audit existing systems for multi-tenant consistency and architectural integrity.
