Architecture Diagram

Purpose

Turn an architecture description or inspected codebase into a self-contained HTML diagram with inline SVG that opens directly in any modern browser.

Routing

• Use when: Use when the user asks to create a technical architecture diagram, infrastructure map, deployment topology, security/data-flow visual, or a polished system diagram artifact they can open in a browser.
• Do not use when: Do not use for text-only summaries, requests that require Mermaid or another explicit diagram format, or non-technical visual design tasks such as UI mockups and marketing graphics.
• Outputs: A standalone HTML architecture diagram plus supporting plan and summary artifacts.
• Success criteria: The final HTML is readable, self-contained, faithful to the described or inspected system, and free of obvious layout collisions.

Trigger Examples

Positive

• Create an architecture diagram for this SaaS stack and give me an HTML file.
• Turn this codebase into a polished cloud architecture diagram.
• Make a system topology diagram showing services, databases, queues, and auth.
• Use the architecture-diagram skill for this request.

Negative

• Summarize this architecture in bullets only.
• Draw this as Mermaid so I can paste it into Markdown.
• Design a landing page hero illustration for our product.
• Create a wireframe for the settings screen.

Parameters

| Name | Type | Required | Description | | ------------- | ------ | -------- | ------------------------------------------------------------------------------------------------------------------------------- | | system_name | string | No | Short system or project name for the header | | diagram_brief | string | No | Structured architecture description | | diagram_type | select | No | Diagram emphasis: auto, system-overview, cloud-infrastructure, deployment, data-flow, security, network-topology, microservices | | output_path | string | No | Workspace-relative or absolute HTML output path |

Workflow Notes

• Start from `assets/template.html`. Do not freehand the outer page shell unless the request explicitly needs a very different composition.
• Read `references/full-guidance.md` before major layout work. It contains the spacing, legend placement, component taxonomy, and arrow-order rules that keep the diagrams readable.
• If the request is based on a local codebase, inspect the code first and derive components conservatively. Missing certainty is better than invented systems.
• Prefer a slightly taller or wider SVG over cramped placement. Expanding the `viewBox` is cheap; unreadable overlaps are not.
• When updating an existing diagram, preserve the established visual language unless the user asks for a redesign.
• In the final assistant response, include a standalone `::html{...}` directive that points at the generated HTML file so the main conversation view can render the diagram inline.

Reference Map

• `references/full-guidance.md`: design system, layout heuristics, and output checklist
• `assets/template.html`: starter HTML/SVG template to customize
• `LICENSE.txt`: upstream MIT license carried with the bundled port

Runtime Prompt

• Runtime prompt is defined directly in `../architecture-diagram.json`.
