Description

Used this for PR #592. Created the reference files, put them in a folder "references", then prompted with:

> Use #file:SKILL.md to make a new skill. Call skill folder "legacy-circuit-mockups" and
  follow #file:INSTRUCTIONS.md adding or moving folder #file:references to the new skill folder

The INSTRUCTIONS.md file basically said, use make-skill-template/SKILL.md to create new skill legacy-circuit-mockups, and move this reference folder with the markdown files to the new skill folder. Delete INSTRUCTIONS.md when done. I had the folder open in explorer so it wasn't properly moved, but copilot moved all the markdown files. I just had to mkdir references in legacy-circuit-mockups, then move the relevant markdown files to it.
