I built this last year because I noticed my coding agents would infer my database schema from migration files and code. Which seemed inefficient.

Its a simple tool that creates compact markdown schema doc(s). Which I could reference in my AGENTS.md or directly in my prompts. I keep the docs up to date by running it as a part of my migration command.

It's a single Go binary, MIT licensed, and works as a CLI or a library. Supports Postgres, MySQL and SQLite.
