Architecture diagram agent
Creates AWS Draw.io diagrams through the YAML layout generator or hand-authored XML for unsupported structures. Outputs editable .drawio plus a reviewed PNG or SVG export.
Workflow
Use canonical design tokens for icon size, subnet colors, fonts, and spacing. Vertex parents follow Cloud → Region → VPC → Subnet → service; edges stay under parent="1". Validate XML and cell counts, require layout score at least 80, export, and inspect the render for truncation or overlap.
Output and verification
Return the editable source, rendered output, relevant build commands, and verification evidence. The content-review gate applies before completion/publication; a successful file write alone is not a passing review.
