erd-designer skillA

erd-designer is agent-read markdown (skill) from kajitiluna/erd-designer: Create and edit ERD Designer .erd files (database entity-relationship diagrams). Use when the user asks to design database tables, add or modify tables, columns, relations, indexes or memos in a .erd file, to export DDL from a .erd file, or to check whether a .erd design matches another revision or a live database..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add kajitiluna/erd-designer/erd-designer@git:20260906.8ba507e
Exact content
mdr add kajitiluna/erd-designer/erd-designer@sha256:637adfb7f3eeed42

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
