SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill helps engineers visualize and communicate complex technical interactions over time by generating Mermaid sequence diagrams that capture multi-service calls, authentication flows, and data exchanges.

Core Features & Use Cases

  • Sequence Diagram Types Supported: API interactions, microservice flows, authentication sequences, database transactions, message queue patterns, WebSocket communications, integration patterns, and error handling.
  • Mermaid Syntax Mastery: Demonstrates basic structure, participant types, arrow types, and advanced features like notes, loops, and parallel paths.
  • Tech-Specific Patterns: Includes REST and OAuth workflows, circuit breakers, event-driven messaging, distributed transactions, and saga-style orchestrations.

Quick Start

Provide a high-level description of the system interactions you want diagrammed, and I will generate the Mermaid sequence diagram accordingly.

FAQPage Schema
How do I generate a Mermaid sequence diagram for microservice communications?

To generate a Mermaid sequence diagram for microservice communications, provide a high-level description of the system interactions. The skill outputs accurate Mermaid syntax capturing participant roles, loops, and parallel paths for complex distributed transactions.

Can I visualize authentication flows and OAuth workflows using sequence diagrams?

Yes, you can visualize authentication flows and OAuth workflows using sequence diagrams. Provide the authentication sequence details, and the skill produces Mermaid syntax with clear participant roles, arrow types, and error-handling constraints.

What is the best way to document API call sequences and distributed transactions?

The best way to document API call sequences and distributed transactions is generating Mermaid sequence diagrams. By providing a high-level narrative of the interactions, you receive diagrams adhering to Mermaid syntax with timing constraints and saga-style orchestrations.

Does Mermaid syntax support advanced sequence diagram features like loops and alt paths?

Yes, Mermaid syntax supports advanced sequence diagram features like loops, alt, and par paths. The skill generates diagrams utilizing these advanced structures alongside notes and participant types to accurately map complex system interactions.

How do I map error handling and circuit breaker patterns in a sequence diagram?

To map error handling and circuit breaker patterns in a sequence diagram, describe the tech-specific integration patterns. The skill generates Mermaid syntax illustrating the sequence, error-handling logic, and fallback mechanisms across the participant roles.
