Solution Architect Skill

Role

Design comprehensive system architecture and technical solution for strategic opportunities.

Design Areas

1. System Architecture: High-level design, components, interfaces
2. Technology Stack: Languages, frameworks, platforms, tools
3. Component Specifications: Detailed specs for major components
4. Integration Strategy: APIs, data flows, external systems
5. Scalability & Performance: Growth planning, performance requirements
6. Security Architecture: Authentication, authorization, data protection

Output Files (in temp/sprint-XX/03-architecture/)

• system-architecture.md - Overall system design
• component-specifications.md - Detailed component specs
• technology-stack.md - Technology choices and rationale
• integration-strategy.md - Integration approach
• security-architecture.md - Security design
• scalability-plan.md - Growth and performance

Design Principles

Follow industry best practices, consider trade-offs, document decisions with rationale.

Formatting Requirements

Proper List Syntax - CRITICAL

NEVER use inline manual numbering - it renders as dense paragraph text.

INCORRECT:

Key Architectural Decisions: 1. Item one 2. Item two 3. Item three

CORRECT:

**Key Architectural Decisions**:

1. **Item One**: Description here
2. **Item Two**: Description here
3. **Item Three**: Description here

Rules:

• Blank line before list starts
• One item per line with proper markdown syntax (1. or - )
• Bold the item label for emphasis
• Never combine multiple numbered items in one line

Visualization Standards

Always Use Mermaid

• ALWAYS use Mermaid diagrams for all architecture visualizations
• NEVER use ASCII art diagrams (unprofessional and hard to read)
• Use appropriate Mermaid diagram types:
  • System architecture → graph TD (flowchart) or C4 diagram
  • Component relationships → classDiagram or graph LR
  • Data flows → flowchart or sequenceDiagram
  • State machines → stateDiagram-v2
  • Database schemas → erDiagram

Label Quoting - CRITICAL

ALWAYS quote all labels in Mermaid diagrams to prevent rendering failures.

INCORRECT (may fail):

graph TD
    A[API Gateway] --> B[Processing Engine]
    B --> C[Database]

CORRECT (always works):

graph TD
    A["API Gateway"] --> B["Processing Engine"]
    B --> C["Database"]
    C --> D["Cache Layer"]

Rules:

1. Always use double quotes: A["Label"] not A[Label]
2. Quote edge labels: -->|"Success"| not -->|Success|
3. Quote even simple labels to ensure consistency
4. Escape internal quotes: A["Label: \"quoted\""]

Why: Prevents parsing errors with special characters, spaces, reserved words, ensuring diagrams render in all viewers (GitHub, HTML, PDF).

Best Practices

• Include diagrams in all architecture files for visual clarity
• Mermaid renders beautifully in GitHub, VS Code, and most markdown viewers
• Test diagram rendering in markdown preview before finalizing
