# Purpose Materialise any Mermaid diagram source (`.mmd`) into a themed, interactive HTML viewer. Output is a single self-contained file; Mermaid 11.4.1 and svg-pan-zoom 3.6.2 are fetched from jsDelivr at runtime. Styling uses a dark-terminal design system (OKLCH CSS tokens, Inter + JetBrains Mono, dark mode, cyan-green accent) consistent with the `html-reporting` shell. **ER-specific features** (entity indexing, search filter) gracefully no-op for non-ER diagram types. # When to use this skill - `.mmd` file exists and user wants a browser viewer - User says: "convert mermaid to html", "make a viewer for X.mmd", "render this schema" - User says: "make this diagram easy to review / explore" - Default output path: same directory as `.mmd`, same basename, `.html` extension - Explicit override via `--out <path>` # When NOT to use this skill - **User wants to generate a new diagram from scratch** -- this skill requires an existing `.mmd` file as input. Use a Mermaid authoring workflow instead. - **User wants to export to PNG, PDF, or SVG** -- this skill produces interactive HTML only. - **Output must be embedded in a CI artifact pipeline** -- use `scripts/build.sh` directly from a CI job without the LLM orchestration steps. - **User wants to edit the diagram content** -- this skill renders existing content; it does not modify `.mmd` source. - **User asks to "create a diagram showing..."** without providing a `.mmd` file -- the prerequisite is an existing source file. # Requ
