I had installed compound engineering and cursor toolkit as well but none of the rules, skills and sub agents were installed. Neither commands. I have reloaded the window. I have installed them uninstalled plugins again and again. It is still not working. When I type / no skills appeared.
For anyone wanting to find a fix, I found temporary solution. What you have to do is go to the plugins’ GitHub and manually installing everything into cursor files. It takes a long time to do it normally so you can use PowerShell. For commands, you can ask the cursor ai using ask mode. Now I currently have sub agents, skills, commands and everything. Hope this helps you guys. Cursor devs still haven’t fixed so this should be temporary solution.
I checked the console from developer tools and it seems that my cursor fails to retrieve data from plugin servers or something like that. Currently I just have skills and rules manually installed
