IBM ACE Message Flow to Mermaid Diagram Generator

Purpose

This skill analyzes IBM AppConnect Enterprise (ACE) message flows and automatically generates mermaid diagrams to visualize:

• Message flow structure and connections
• Node types and configurations
• Message routing paths
• Error handling flows
• Data transformation pipelines

Usage

Analyze a Message Flow File

@skill ibm-ace-mermaid "Analyze /path/to/messageflow.msgflow"

Generate Diagram with Custom Options

@skill ibm-ace-mermaid "Create mermaid diagram for ACE flow: include error handlers, color-code by node type"

Compare Multiple Flows

@skill ibm-ace-mermaid "Compare flows flow1.msgflow and flow2.msgflow, show differences in diagram"

Capabilities

Message Flow Parsing

• Supported Formats: .msgflow (XML), .xml, JSON representations
• Node Types: Input, Output, Filter, Compute, Database, HTTP Call, Message Broker, etc.
• Connections: Identifies message routing, success paths, error paths
• Configuration: Extracts node settings, properties, and parameters

Diagram Generation

• Graph Visualization: Flow structure with proper node positioning
• Color Coding: Different colors for different node types
• Path Highlighting: Success paths (solid), error paths (dashed)
• Annotations: Labels for transformations, conditions, and routing logic
• Legend: Includes node type definitions and path meanings

Analysis Output

• Flow complexity metrics
• Entry and exit points
• Error handling paths
• Data transformation steps
• External service integrations

Examples

Input: IBM ACE Message Flow (XML)

<messageFlow name="OrderProcessing">
  <nodes>
    <inputNode name="HTTPInput" nodeType="HTTPInputNode"/>
    <computeNode name="ValidateOrder" nodeType="ComputeNode"/>
    <databaseNode name="InsertToDB" nodeType="DatabaseNode"/>
    <outputNode name="HTTPOutput" nodeType="HTTPReplyNode"/>
  </nodes>
  <connections>
    <connection source="HTTPInput" target="ValidateOrder"/>
    <connection source="ValidateOrder" target="InsertToDB"/>
    <connection source="InsertToDB" target="HTTPOutput"/>
  </connections>
</messageFlow>

Output: Mermaid Diagram
