Diagram Design System
Professional diagrams in 41 types, on-brand and export-ready
- What
- Professional diagrams in 41 types, on-brand and export-ready
- Cost
- Free
- Needs
- none mandatory — the skill renders diagrams as HTML in the browser (free). Optional: Python 3.10+ with a CairoSVG-based stack only if you want direct PNG export; otherwise the skill falls back to SVG output. You may also import existing draw.io, Mermaid, Excalidraw files or a PDF as a starting point.
- Install
- Copy the installer prompt below into your Muse — your agent does the rest.
Curated by Skill Harbor — an editorial design system for technical diagrams: 41 diagram types (flowcharts, architecture, sequence, ER, swimlane, quadrant, radar, timelines, state machines and more), a structured intake interview, brand rules (color, typography, spacing), accessibility defaults, and layered HTML/SVG output with optional PNG export. Discovered via skills.sh. By @cathrynlavery, listed here with credit to its creator. Honest caveats: the default output is HTML rendered in the browser — direct PNG export needs a Python stack you may have to install; you can also import existing draw.io, Mermaid or Excalidraw files instead of starting from scratch. It's a design method, not a guarantee of taste: the intake answers you give determine the result. Skill Harbor never reviews the code, review it yourself before use. Not verified.

Install
Prerequisites: none mandatory — the skill renders diagrams as HTML in the browser (free). Optional: Python 3.10+ with a CairoSVG-based stack only if you want direct PNG export; otherwise the skill falls back to SVG output. You may also import existing draw.io, Mermaid, Excalidraw files or a PDF as a starting point. Install "Diagram Design System" for me. It gives Muse an editorial system for creating professional technical diagrams: a structured intake interview, 41 diagram types, brand and accessibility rules, layered HTML/SVG output, and optional PNG export. Repository: https://github.com/cathrynlavery/diagram-design 1. Fetch the SKILL.md file (and any helper files) from the repository path into a temporary folder and summarize what it does in one or two sentences. 2. Safety check: review the SKILL.md and scripts for anything suspicious (unexpected network calls, shell commands, credential harvesting). This repo should contain zero secrets in code, credentials only via the secure vault, allowed hosts declared in the SKILL.md. Verify that holds here; STOP on any red flag and tell me. 3. Install it as a skill: copy SKILL.md and its helper files into the agent's skills directory, in a folder named "diagram-design". 4. Verify with no network calls: frontmatter valid, files in place. 5. Report what was installed, where, and what I still need to do myself (e.g. decide whether I want the optional Python PNG-export stack, and share my brand colors/typography for on-brand output). GitHub is optional: if I have a GitHub account or the gh CLI, you may use it; otherwise public access is fine. Never require it unless it's in the prerequisites above. Rules: don't touch anything outside the temp folder and the install target. If anything looks off, stop and ask me.
Questions
How do I install a build?
Every product page includes a copy-paste install prompt. Paste it into your Muse and it sets the build up for you — no manual configuration.
Where does my money go?
Straight to the seller. Skill Harbor never processes payments: checkout happens on the seller’s own page, usually Stripe.
What does the ✓ next to a creator’s name mean?
It means we confirmed the identity of the person behind the listing. It says nothing about the code itself — always check a build before installing it.
