External Diagram Mermaid Generate

This generates Mermaid diagrams for Salesforce architecture with ASCII fallbacks when you need something that renders in plain text. It covers OAuth flows, ERDs, integration sequences, and Agentforce structure maps. The skill bundles templated flows for every OAuth grant type and pre-built ERD models for Sales Cloud, Service Cloud, and B2B Commerce, so you're not starting from scratch. It also includes a Python preview server and an org metadata query script to ground diagrams in real schema. The workflow is sensible: pick your diagram type, gather context, generate Mermaid, add ASCII if needed, then explain what you drew. Worth using if you document Salesforce integrations in markdown or need diagrams that live in GitHub issues without image uploads.

Files

external-diagram-mermaid-generate: Salesforce Diagram Generation

Use this skill when the user needs text-based diagrams: Mermaid diagrams for architecture, OAuth, integration flows, ERDs, or Agentforce structure, plus ASCII fallback when plain-text compatibility matters.

Scope

In Scope

Use external-diagram-mermaid-generate when the user wants:

Mermaid output
ASCII fallback diagrams
architecture, sequence, flowchart, or ERD views in markdown-friendly form
diagrams that can live directly in docs, READMEs, or issues

Out of Scope — Delegate elsewhere when the user wants:

non-Salesforce systems only → use a more general diagramming skill
object discovery before an ERD → platform-custom-object-generate or platform-custom-field-generate
