When to Use This Skill

Use this skill when... Use d2-diagrams instead when...
Embedding a diagram directly in a GitHub README or wiki The output needs rich styling, custom themes, or icons
Authoring sequence diagrams or simple flowcharts The diagram has deeply nested containers or complex layouts
Targeting platforms that natively render Mermaid (GitHub, GitLab, Notion) Generating standalone SVG/PDF architecture diagrams
Diagrams must travel as plain text alongside the source A premium layout engine (tala) materially improves the result
