Template Index

This skill indexes all available templates. Each template demonstrates the correct XML structure with the full <mxfile> wrapper, proper layers, edge routing, shadows, and containers.

Template Files

Template	File	Use For
Flowchart	`commands/create.md` (Template Library section)	Process flows, algorithms
Sequence	`commands/create.md` (Sequence Diagram Template)	API flows, request traces
ER Diagram	`commands/create.md` (ER Diagram Template)	Database schemas
C4 Architecture	`commands/create.md` (C4 Architecture Template)	System architecture
UML Class	`commands/create.md` (UML Class Diagram Template)	OO design
Kubernetes	`commands/create.md` (Kubernetes Diagram Template)	K8s topology
Swimlane	`commands/create.md` (Swimlane Diagram Template)	Cross-team flows
Mind Map	`commands/create.md` (Mind Map Template)	Brainstorming
Simple Flowchart	`skills/xml-generation/SKILL.md` (Example 1)	Quick processes
AWS Architecture	`skills/xml-generation/SKILL.md` (Example 2)	Cloud infra
UML Sequence	`skills/xml-generation/SKILL.md` (Example 3)	Detailed sequences

Template Requirements

Every template MUST include:

<mxfile> wrapper (never bare <mxGraphModel>)
background="none" on <mxGraphModel>
At least 2 layers (content + annotations)
Title annotation cell on the annotations layer
shadow=1; on primary shapes
html=1; with <b> tags on labels
edgeStyle=orthogonalEdgeStyle;rounded=1;jettySize=auto; on edges
strokeWidth=2; on primary flow edges
Explicit exitX/exitY/entryX/entryY on edges between non-aligned shapes
Containers for grouped elements
Legend if 3+ color categories
