Description
Use when users need Mermaid diagrams for Arduino code structure, state machines, timing diagrams, task architecture, or workflow documentation.

Mermaid Diagram Generator

Generate Mermaid diagrams from Arduino and embedded-system concepts without loading unnecessary detail up front.

Resources

  • scripts/generate_diagram.py - CLI generator for diagram output
  • references/diagram-templates.md - Mermaid templates by diagram type
  • references/code-patterns.md - code-to-diagram extraction heuristics
  • references/validation-checklist.md - rendering and syntax checks

When to Use

Use this skill when the request asks to:

  • visualize a state machine
  • turn code into a flowchart
  • document timing or protocol sequences
  • show FreeRTOS task relationships
  • add a diagram to project documentation

Do not use it for tiny code snippets where a diagram adds no clarity.

Workflow

  1. Identify the diagram type:
    • state flow -> open references/code-patterns.md
    • timing or protocol sequence -> open references/diagram-templates.md
    • task architecture -> open both code-patterns.md and diagram-templates.md
  2. Prefer the simplest diagram that explains the behavior.
  3. Use scripts/generate_diagram.py when the input is structured enough for automation.
  4. Run through references/validation-checklist.md before presenting the final Mermaid output.

Verification

  • Mermaid syntax parses without errors.
  • The diagram uses the correct abstraction level for the request.
  • State names, transitions, or signals match the source material exactly.
  • The output is readable without reverse-engineering the code.

Integration

  • Pair with freertos-patterns for task and synchronization diagrams.
  • Pair with arduino-code-generator when a generated sketch also needs visual documentation.
  • Pair with readme-generator when the diagram should ship in repository docs.
