sf-diagram-mermaid

sf-diagram-mermaid is a skill for Claude Code, Codex from Jaganpro/sf-skills. It costs 85 tokens per session (1,296 once invoked), scanned A, original, MIT.

A text-based diagramming tool for Salesforce architecture, data relationships, integrations, and process flows using Mermaid diagrams.

In plain words
What is it for?
Use it to create entity-relationship diagrams, sequence diagrams, flowcharts, OAuth flows, integration views, and plain-text fallbacks.
Why use it?
It makes system structure easier to document in markdown files, READMEs, and issue trackers without requiring image-editing software.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

sf-diagram-mermaid scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/mermaid_preview.py, scripts/query-org-metadata.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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

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
