What it does
drawio-skill is a skill for AI coding assistants such as Claude Code, Cursor and Codex. Describe a diagram in plain words and it creates an editable draw.io file, checks the picture and fixes overlaps.
It can also build diagrams from real sources, such as a codebase, cloud setup files or database designs, and keep them up to date as things change without losing your manual tweaks.
Diagrams can be exported to an interactive web page, a PowerPoint deck and other formats.
Who it's for
Software developers and architects who want diagrams of their systems that stay accurate.
