How does it visualize the database schema?

It generates code for Mermaid.js erDiagrams, which provides a clean, visual representation of your tables and relationships directly within your markdown files.

What database technologies are supported?

It detects common ORMs and drivers such as Prisma, Mongoose, Sequelize, and native drivers for PostgreSQL, MongoDB, and MySQL.

Will it overwrite my existing documentation?

No, the skill is idempotent; it checks for the existence of files like api_spec.md and skips them if they already exist to protect your manual updates.

Does this skill support GraphQL?

Yes, it is designed to detect and document various API types including REST, GraphQL, and gRPC based on the source code scan.

Learning & Documentation

Generates comprehensive OpenAPI specifications and Mermaid-based database ER diagrams automatically from project source code.

This skill automates the technical documentation process by creating standardized API specifications and database schemas. It acts as a specialized worker that detects backend frameworks like Express or FastAPI and database tools like Prisma or Mongoose to generate production-ready documentation. By producing OpenAPI 3.0 compliant specs and visual ER diagrams using Mermaid.js, it ensures that your system architecture is clearly mapped and easily accessible to all team members without manual overhead.
