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