sf-diagram-mermaid: 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.
When This Skill Owns the Task
Use sf-diagram-mermaid 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
Delegate elsewhere when the user wants:
- rendered PNG/SVG images or polished mockups → sf-diagram-nanobananapro
- non-Salesforce systems only → use a more general diagramming skill
- object discovery before an ERD → sf-metadata
Supported Diagram Families
| Type | Preferred Mermaid form | Typical use |
|---|
| OAuth / auth flows | sequenceDiagram | Authorization Code, JWT, PKCE, Device Flow |
| ERD / data model | flowchart LR | object relationships and sharing context |
| integration sequence | sequenceDiagram | request/response or event choreography |
| system landscape | flowchart | high-level architecture |
| role / access hierarchy | flowchart | users, profiles, permissions |
| Agentforce behavior map | flowchart | agent → topic → action relationships |
Required Context to Gather First
Ask for or infer:
- diagram type
- scope and entities / systems involved
- output preference: Mermaid only, ASCII only, or both
- whether styling should be minimal, documentation-first, or presentation-friendly
- for ERDs: whether org metadata is available for grounding
Recommended Workflow
1. Pick the right diagram structure
- use
sequenceDiagram for time-ordered interactions
- use
flowchart LR for ERDs and capability maps
- keep a single primary story per diagram when possible
2. Gather data
For ERDs and grounded diagrams:
- use sf-metadata when real schema discovery is needed
- optionally use the local metadata helper script for counts / relationship context when appropriate
3. Generate Mermaid first
Apply:
- accurate labels
- simple readable node text
- consistent relationship notation
- restrained styling that renders cleanly in markdown viewers
4. Add ASCII fallback when useful
Provide an ASCII version when the user wants terminal compatibility or plaintext documentation.
5. Explain the diagram briefly
Call out the key relationships, flow direction, and any assumptions.
High-Signal Rules
For sequence diagrams
- use
autonumber when step order matters
- distinguish requests vs responses clearly
- use notes sparingly for protocol detail
For ERDs
- prefer
flowchart LR
- keep object cards simple
- use clear relationship arrows
- avoid field overload unless the user explicitly asks for field-level detail
- color-code object types only when it improves readability
For ASCII output
- keep width reasonable
- align arrows and boxes consistently
- optimize for readability over decoration
Output Format
## <Diagram Title>
### Mermaid Diagram
```mermaid
<diagram>
```
### ASCII Fallback
```text
<ascii>
```
### Notes
- <key point>
- <assumption or limitation>

| 48–59 | functional but could be clearer |
| 35–47 | needs structural improvement |
| < 35 | inaccurate or incomplete |
