Generate a shareable diagrammo.app URL for a DGMO diagram.

Open a DGMO diagram in the Diagrammo desktop app (macOS only). Falls back to browser preview if the app is not installed.

List all supported DGMO chart types with descriptions.

Get the DGMO language reference documentation. Optionally filter by chart type.

Render one or more DGMO diagrams and open an HTML preview in the browser. Supports theme toggle and optional source display. For DGMO syntax call get_language_reference (e.g. color a label with a trailing color name: "Sales red").

Generate a polished HTML report with multiple DGMO diagrams, table of contents, and optional source blocks. Opens in browser by default. For DGMO syntax call get_language_reference (e.g. color a label with a trailing color name: "Sales red").

Returns: confidence banner (high/medium/ambiguous), up to 3 ranked candidates with descriptions, matched trigger phrases, and pointers to get_examples for starter DGMO stubs.

Get example DGMO diagrams for a chart type. Returns real-world examples from the gallery that demonstrate syntax patterns. Use these as few-shot references when generating new diagrams.

Migrate legacy DGMO content (pre-0.18.0) to the unified §1.4 same-line metadata grammar. Input is the source of a .dgmo file or a single fenced ```dgmo block; output is the migrated source plus a unified-style diff. The | metadata delimiter was removed in 0.18.0 in favor of Foo k: v, k: v inline. Use this when you encounter a .dgmo file authored against 0.17.x that emits E_PIPE_OPERATOR_REMOVED diagnostics.
