Documentation

README

Excerpt

PlantUML Syntax Reference

A comprehensive reference for PlantUML diagram types with a focus on C4-PlantUML for architecture diagrams. This skill provides syntax documentation adapted from the SpillwaveSolutions/plantuml project, supplemented with ArcKit-specific C4 layout conflict rules and best practices.

This skill ships reference material, not runnable scripts. Read the relevant reference file with Read, apply the syntax, and write the diagram into the user's artefact. Do not Bash-execute anything from references/ — they are PlantUML/C4 syntax docs, not commands.

Supported Diagram Types

Select the appropriate diagram type and read the corresponding reference file:
