Choose and create the right diagram type (UML, C4, ER, BPMN, domain) in standard notation; Mermaid-compatible output. Use when: create diagram, draw diagram, which diagram, diagram this, visualize, sequence diagram, class diagram, flowchart, architecture diagram, ER diagram, state diagram, activity diagram, context diagram, swimlane.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Diagramming Skill

## Goal

Select the appropriate diagram type for the communication need, create it using correct
notation and standards, and produce output in Mermaid syntax (or PlantUML as fallback).
Diagrams are communication tools — choose based on what question the reader needs answered.

## Diagram Selection Guide

```
Question being answered → Diagram type

"What IS the system and who uses it?"           → System Context (C4 Level 1)

"What are the components inside a container?"    → Component Diagram (C4 Level 3)
"How are business objects structured?"           → Domain Class Diagram
"How are data tables related?"                   → Entity-Relationship Diagram
"What packages/modules exist?"                   → Package Diagram
"How does process X flow step by step?"          → Sequence Diagram
"What are all the paths through a use case?"     → Activity Diagram
"What states can object X be in?"                → State Machine Diagram
"Who does what in a process?"                    → Swimlane Diagram (BPMN or Activity)

How to install

The exact contents, by fingerprint

mdr add andreibesleaga/gabbe/diagramming@sha256:9c0cb86c2c92850d

The line at the top of this page pins the label git:20261014.de0823c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
