Can't install a skill folder zipped as a .skill file

Hello ! 
I’ve been working hard to create a skill thad teach agents to work with some of the most importants UI guidelines at my company.
I’ve zipped it as a .skill file as it’s usually done to share and install skills.

Figma seems to not accept this format. Any way to fix that ?

Hey hey ​@Hugo-M 🤩 Great question. Thanks for including your screenshot.

Custom skills need to be uploaded as a single Markdown (.md) file. Zipped bundles, including .skill files, aren't supported.

So you shouldn't need to rewrite anything:

  • Unzip your .skill file. There's already a YOUR_COOL_SKILL.md inside it
  • In the chat prompt box, click +, then Skills, then Add skill
  • Use the Upload a file button and select that YOUR_COOL_SKILL.md You can also try dragging the file in, as a second test

One thing to check before you upload: if your instructions point to anything in a scripts/, references/, or assets/ folder, those directories aren't supported either. You'll need to add it into the SKILL.md itself, or trim it out.

Question — is this error happening when you are dragging files into the upload area? In my quick tests, this is how I triggered the same warning.

Let me know if you are able to get your non-zipped .md file to upload. Have fun prompting! — Jaycee

Hello,

Thanks for the answer! That's what I suspected.

Unfortunately, the whole point of that skill (at least what I was trying to achieve) was to leverage progressive disclosure to reference a huge references folder. Including everything in a single .md file doesn't make sense as a skill anymore…

Anyway, I now know Figma's limitations, so I can try working with simpler .md files instead.
