NW-DIAGRAM: Architecture Diagram Generation

Wave: CROSS_WAVE | Agent: Morgan (nw-solution-architect) | Command: *create-diagrams

Overview

Generate architecture diagrams from design documents. Supports C4 model levels (context|container|component) in Mermaid|PlantUML|C4 format. Audience-appropriate: high-level context for stakeholders|component details for developers|deployment topology for operations.

Context Files Required

• docs/product/architecture/brief.md (SSOT — component boundaries, technology stack, design decisions)

Workflow

1. Read Context — Load docs/product/architecture/brief.md. Extract component boundaries, technology stack, and design decisions. Gate: architecture brief loaded.
2. Resolve Configuration — Determine diagram_type (component|deployment|sequence|data|context), format (mermaid|plantuml|c4), level (context|container|component), and output_directory. Gate: all configuration parameters resolved.
3. Invoke Agent — Delegate to @nw-solution-architect with *create-diagrams for {architecture-component}, passing context files and resolved configuration. Gate: agent invoked with all parameters.
4. Validate Output — Verify diagrams render without syntax errors and files exist in output_directory. Gate: all success criteria pass.
5. Handoff — Return deliverables to invoking agent. Gate: architecture diagrams available in configured format.

Success Criteria

• Diagrams accurately represent current architecture
• Audience-appropriate detail level applied
• Diagrams render without syntax errors
• Output files created in configured directory

Handoff To: {invoking-agent-returns-to-workflow} Deliverables: Architecture diagrams in configured format

Examples

Example 1: Generate C4 container diagram

/nw-diagram payment-service --diagram_type=component --format=mermaid --level=container

Morgan reads architecture docs and produces a Mermaid container diagram showing service boundaries, data stores, and external integrations.
