Adding project rules becomes skills in 2.3.8

[meebox (昕暐 黃)]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Adding a project rule(custom rule) becomes a skill. It create a SKILL.md inside the .cursor/skills/<rule name>. I expect this new version fix the bug which creates old .mdc files for rules instead of creating RULD.md files.

Steps to Reproduce

Just add a new project rule(custom rule) will see.

Expected Behavior

It doesn’t create rules.

I found that it only happens with my cursor accout logging by Google accout [email protected]. I’ve tested on various machines. When log in with that account, there’s an Import Agent Skills option in the Rules and Commands settings, see bellow
