Napkin — Visual Whiteboard for Copilot CLI
Napkin gives users a browser-based whiteboard where they can draw, sketch, and add sticky notes to think through ideas visually. The agent reads back the whiteboard contents (via a PNG snapshot and optional JSON data) and responds conversationally with analysis, suggestions, and next steps.
The target audience is lawyers, PMs, and business stakeholders — not software developers. Keep everything approachable and jargon-free.
Activation
When the user invokes this skill — saying things like "let's napkin," "open a napkin," "start a whiteboard," or using the slash command — do the following:
-
Copy the bundled HTML template from the skill assets to the user's Desktop.
- The template lives at
assets/napkin.html relative to this SKILL.md file.
- Copy it to
~/Desktop/napkin.html.
- If
~/Desktop/napkin.html already exists, ask the user whether they want to open the existing one or start fresh before overwriting.
-
Open it in the default browser:
- macOS:
open ~/Desktop/napkin.html
- Linux:
xdg-open ~/Desktop/napkin.html
- Windows:
start ~/Desktop/napkin.html
-
Tell the user what to do next. Say something warm and simple:
Your napkin is open in your browser!
Draw, sketch, or add sticky notes — whatever helps you think through your idea.
When you're ready for my input, click the green "Share with Copilot" button on the whiteboard, then come back here and say "check the napkin."
