siren_convert
Convert a plain Mermaid flowchart to Siren syntax by automatically adding @icon annotations based on node labels and IDs. Infers icons for 100+ technologies (react, postgresql, redis, kafka, nginx, kubernetes, etc.). Sequence diagrams are returned unchanged — they are already fully compatible. Returns the enriched Siren source and a list of icons that were added.
siren_url
Generate a shareable URL that opens a Siren diagram in the browser editor. Returns a URL the user can click to preview or share the diagram.
siren_validate
Validate Siren diagram syntax. Returns a success confirmation or a list of errors. Use this after writing any Siren diagram.
