Overview
external-diagram-mermaid-generate is a Salesforce architecture diagram skill that generates professional diagrams using Mermaid syntax with ASCII art fallback for terminal compatibility.
Features
- OAuth Flows - Authorization Code, PKCE, JWT Bearer, Client Credentials, Device Flow
- Data Models - ERD diagrams with platform-custom-object-generate integration
- Integrations - Sequence diagrams for API patterns
- Architecture - System landscape overviews
- Role Hierarchies - Security model visualization
- Agentforce - Agent topic and action flows
- Accessible - Color-blind friendly palette
- Terminal Friendly - ASCII fallback for all diagrams
Quick Start
# Generate an OAuth diagram
"Create a JWT Bearer OAuth flow diagram"
# Generate a data model
"Create an ERD for Account, Contact, and Opportunity"
