SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Mermaid diagram generation helps teams visualize architecture, module relationships, data flows, and Pact 5 sequences, reducing miscommunication and onboarding time.

Core Features & Use Cases

  • Generate flowchart diagrams to map module dependencies, deploy orders, and capability hierarchies.
  • Create sequenceDiagram illustrations for transaction flows, cross-system interactions, and agent communications.
  • Render classDiagram, stateDiagram, and erDiagram to capture schema relationships and lifecycle states.
  • Enforce conventions such as one concept per diagram, consistent colors, edge labels, and optional annotations for gas costs.

Quick Start

Describe your architecture and I will generate the corresponding Mermaid diagram.

FAQPage Schema
How do I generate Mermaid diagrams for module relationships automatically?

You can generate Mermaid diagrams by providing text descriptions of module relationships and workflows. The tool automates rendering into flowcharts and sequence diagrams while enforcing consistent styling and edge labeling.

Can I visualize Pact 5 transaction flows using sequence diagrams?

Yes, you can visualize Pact 5 transaction flows using sequenceDiagram illustrations. The tool maps cross-system interactions and agent communications, applying optional gas-cost annotations to satisfy transaction sequence constraints.

What is the best way to document architecture with consistent diagram styling?

Documenting architecture with consistent styling requires enforcing one concept per diagram, uniform colors, and edge labels. This approach maps module dependencies and capability hierarchies into clear flowchart diagrams.

Does this diagram generation approach support state and entity-relationship diagrams?

Yes, the approach supports rendering stateDiagram and erDiagram formats. These capture schema relationships and lifecycle states, reducing miscommunication and onboarding time for teams visualizing complex architectures.

When do I need to use edge labeling and gas cost annotations in architecture diagrams?

Edge labeling and optional gas-cost annotations are needed when mapping data flows and transaction sequences across Pact 5 and related systems. These constraints ensure diagrams accurately reflect module dependencies, deploy orders, and capability hierarchies.
