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
