Hey, this is a known issue. Skills installed via third-party tools (Codex desktop, npx skills add, etc.) are currently being classified as Rules instead of showing up under Skills in Cursor settings. A few users have reported the same thing recently:
The ~/.codex/skills/ path is supported as a skills directory per the docs, so your setup looks correct.
Can you share the contents of one of the SKILL.md files from ~/.codex/skills/? I’m especially interested in the frontmatter at the top. That’ll help confirm whether the metadata is being parsed correctly or if Cursor is misclassifying them either way.
The team is aware. No ETA yet, but your report (and the others) helps us prioritize it.
