Curated by Skill Harbor — a free, open-source skill (MIT) from GitHub's awesome-copilot collection, listed here with credit to its creator. Turns a plain-language description into a ready-to-open Excalidraw diagram: flowcharts, relationship diagrams, mind maps, system architecture diagrams, data flow diagrams, swimlane business flows, class diagrams, sequence diagrams, and ER diagrams — generated as `.excalidraw` JSON files that open directly in the Excalidraw app or website, where every shape stays editable. It walks through understanding your request, picking the diagram type, extracting the structured information, laying it out, validating the output against a checklist, and handing you the file with instructions to open it. Includes example prompts, troubleshooting, element-count guidelines so diagrams stay readable, and an optional icon-library workflow for richer AWS-style diagrams. Discovered via skills.sh. Honest note: it produces the diagram data, not a rendered image — you open the `.excalidraw` file in Excalidraw to see and edit it; diagram quality depends on how clearly you describe what to visualize; very large diagrams with icon libraries can consume significant tokens (the skill itself warns about this). skills.sh Trust Hub: unverified. Skill Harbor never reviews the code, review it yourself before use. Not verified.

Install
Prerequisites: a clear description of what to visualize (the process, system, or relationships). To view and edit the result, open the .excalidraw file in the Excalidraw app or at excalidraw.com — no account or API keys required. Install "Excalidraw Diagram Generator Skill for Muse" for me. Turns plain-language descriptions into editable Excalidraw diagrams — flowcharts, mind maps, architecture diagrams, sequence/class/ER diagrams, swimlane flows — delivered as .excalidraw JSON files that open directly in Excalidraw. Repository: https://github.com/github/awesome-copilot 1. Fetch the SKILL.md file for the excalidraw-diagram-generator skill (and any helper files) from the repository 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 "excalidraw-diagram-generator". 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. describe the first diagram I want and open the .excalidraw output in Excalidraw). 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.
