Hope Agent's chat renders Mermaid blocks natively, so the diagram appears inline. version 1.0.0 author Hope Agent license MIT metadata {\"hermes\":{\"tags\":[\"office\",\"diagram\",\"visualization\",\"mermaid\",\"architecture\"],\"related_skills\":[]}} Mermaid Diagram When to Use Trigger phrases: \"draw a diagram\", \"flowchart for …\", \"sequence diagram\", \"architecture diagram\", \"ER diagram\", \"state machine\", \"gantt chart\", \"画一个流程图\", \"画个架构图\". Mermaid is rendered natively in Hope Agent chat (via Streamdown). Just emit a fenced ```mermaid block — the user sees the rendered SVG, no setup. For diagrams Mermaid can't express (organic shapes, custom illustrations, hand-drawn style) consider drawing-tool skills (e.g. excalidraw from Hermes Agent or drawio from Anthropic marketplace) — those need to be installed via Quick Import.

(process / structure / relationships / timeline) Who's the audience? (engineers / execs / customers) Level of detail? (high-level overview / fine-grained) Pick the simplest type that fits — flowchart > sequence > state. Don't reach for classDiagram if a flowchart works. Sketch nodes first, edges second — list the entities (boxes), then connect them. Avoid dense edge spaghetti. Iterate small — start with 5-7 nodes. Add detail only after the user confirms the structure. Verify renderability — if you reference Mermaid syntax that's iffy (e.g. classDiagram with annotations), keep it minimal. The user will see if it doesn't render. Style Rules One concept per diagram — if you're tempted to add a second flow, split into two diagrams Consistent shape vocabulary : [Square] = process / action (Round) = entity / data {Diamond} = decision ([Stadium]) = start / end [(Cylinder)] = database / storage ((Circle)) = external system Direction : TD (top-down) for hierarchies, LR (left-right) for pipelines / data flows Labels short — node labels ≤ 4 words. Detail goes in surrounding prose. Use Note over in sequence diagrams to explain non-obvious behavior, not for narration Multi-Diagram Output When asked for \"a few diagrams\" or \"show me the system from different angles\", output 2-3 separate ```mermaid blocks with prose between them explaining what each shows. Here's the system at three levels: **1. High-level data flow:** \\`\\`\\`mermaid flowchart LR ... \\`\\`\\` **2. Login sequence (zoom into auth):** \\`\\`\\`mermaid sequenceDiagram ... \\`\\`\\` **3. Database relationships:** \\`\\`\\`mermaid erDiagram ... \\`\\`\\` Common Pitfalls Mistake Fix Single diagram with 30+ nodes Split into 2-3 diagrams by concern Mixing types (flowchart with class fields) Pick one type; for hybrid views, do multi-diagram All boxes look the same Use shape vocabulary (decision = diamond, etc.) Long node labels Move detail to prose; keep nodes ≤ 4 words Unicode quotes ( \"smart quotes\" ) breaking syntax Use ASCII \" everywhere in Mermaid blocks Mermaid ; line endings forgotten when used Either use newlines OR ; consistently, not mixed Forgot fenced block tag Block must be mermaid (not just ) for HA chat to render Limitations to Surface to User No floating positioning / pixel-perfect layouts (Mermaid auto-lays out) Limited styling (colors via classDef but verbose) Some node shapes don't compose (e.g. cylinders inside subgraphs can be quirky) For organic / hand-drawn / heavily-styled diagrams, recommend a draw.io / excalidraw skill instead",
