Diagram Maker
Create diagrams as artifacts, not prose. Choose one output mode:
clean-svg: educational concepts, physical systems, processes, lifecycle, simple data flow.architecture-svg: software/cloud/infra topology, services, databases, queues, trust zones.excalidraw: editable hand-drawn whiteboard, flowchart, sequence, architecture sketch.
Routing
- User wants editable/collaborative: choose Excalidraw.
- User wants polished standalone browser output: choose SVG/HTML.
- Software architecture with infra components: choose architecture SVG.
- Science, product, process, concept map, physical object: choose clean SVG.
- Unsure: ask one short question only if output format matters; otherwise choose clean SVG.
Workflow
- Extract nodes, groups, labels, and directed relationships.
- Pick layout first: left-to-right, top-down, hub-spoke, swimlanes, layered stack, sequence.
- Keep labels short. Prefer 5-9 main elements over dense diagrams.
- Generate the file at the requested path, or
./diagram.html / ./diagram.excalidraw.
- Verify syntax by opening/parsing when feasible.
SVG/HTML rules
- Single standalone
.html file with inline CSS and inline SVG.
- No external fonts, JS, images, gradients, glows, decorative blobs, or remote assets.
- Use semantic colors, not rainbow sequences: neutral, input, process, storage, external, risk.
- Draw connectors before nodes so arrows sit behind boxes.
- Every connector path has
fill="none" and a marker arrow when directed.
- Leave 24px text padding inside boxes; do not let text touch borders.
- Legend only when symbols/colors are not obvious.
SVG template
Use references/svg-template.md as the wrapper and replace <!-- SVG -->.
Excalidraw rules
- Save
.excalidraw JSON with type, version, source, elements, and appState.
- Use bound text for shape labels. Do not use a nonstandard
label property.
- Keep bound text immediately after its container in the elements array.
- Minimum labeled shape: 120x60. Minimum body text: 16px.
- Use roughness
1, fontFamily: 1, and simple fills.
For exact Excalidraw element snippets, read references/excalidraw-patterns.md.
PilotDeck Migration Note

- Review status: candidate for PilotDeck native skills pack.
- Platform-specific OpenClaw/Hermes metadata was removed or should be ignored during review.
